When you upload work files via gigabit broadband while smoothly streaming 4K IPTV programs, you may not realize that behind these "simultaneous online" high-speed experiences lies an "intelligent dispatcher of optical signals" — the PON Coexistence Wavelength Division Multiplexer (CEx-WDM). It not only makes "one optical fiber for all services" a reality but also serves as the core driver for future 10G and beyond-10G broadband upgrades.
 
PON XGS-PON CATV Device

 

1. "Classify and Package" Optical Signals to Turn One Fiber into a "Multi-Lane Highway"

In optical fiber communication, optical signals for different services (such as internet access, TV viewing, and network testing) originally required separate fibers. The core of the CEx-WDM device is using Wavelength Division Multiplexing (WDM) to "attach wavelength labels" to optical signals: it classifies and packages data streams from GPON (gigabit broadband), XGS-PON (10G broadband), NG-PON2 (next-generation ultra-high-speed broadband), even RF signals for Cable Television (CATV) and maintenance signals for Optical Time-Domain Reflectometry (OTDR) by "wavelengths", enabling them to transmit simultaneously in a single fiber without interference.

 

To illustrate, it’s like assigning "dedicated lanes" (different wavelengths) to traffic bound for different destinations, creating a "multi-lane highway" within one optical fiber. This eliminates the need for duplicate fiber laying while allowing all services to "run at full speed".
 

2. Old Broadband Upgrades to New Broadband in Seconds Without Changing Fibers

For many households and enterprises, existing networks still operate at the GPON (gigabit-level) or even EPON (100 Mbps-level) stage. With CEx-WDM, operators can upgrade old networks "in one step" to XGS-PON (10G symmetric broadband) without laying new fibers, and smoothly transition to NG-PON2 (supporting over 40G ultra-high speed) in the future.

 

Imagine this: The optical fiber installed in your community years ago could only support gigabit speeds, but after adding this device, you can directly access 10G broadband without digging walls or rewiring. Transferring large files or hosting 8K video conferences becomes seamless — this is the magic of "upgrading without changing fibers".
 

3. From Households to Future Technologies, It Exists Everywhere

The application scenarios of this device have long permeated all aspects of our lives and industries:

 

  • Households & Communities: In a community’s optical distribution box, it distributes "multi-service signals" from the main fiber to each household, enabling simultaneous use of "gigabit broadband + IPTV + cable TV" with a seamless experience.
  • Operator Machine Rooms: On the side of OLT (Optical Line Terminal) devices in core machine rooms, it acts as a "central signal dispatching room", efficiently integrating GPON/XGS-PON signals from thousands of households with CATV and OTDR signals before connecting to the urban backbone network.

 

Future Scenarios: It also paves the way for "future demands" like 5G base station backhaul, industrial internet (e.g., low-latency networking for hundreds of devices in smart factories), and metaverse interaction — NG-PON2 technology allows a single fiber to carry over 40G bandwidth, sufficient to support technological evolution for a decade or more.

 

4. It is the "Invisible Driver" of Broadband Upgrades, Changing More Than Just Speed

For operators, CEx-WDM means cost savings and convenience: they can launch multiple services (gigabit broadband, 10G dedicated lines, high-definition TV, etc.) simultaneously without repeating fiber network construction. For users, it brings a leap in experience — from "merely accessing the internet" to "high-speed internet + simultaneous multi-services". In the future, watching 8K videos or playing metaverse games will no longer suffer from stutters due to "insufficient bandwidth".

 

In short, this tiny passive device is a crucial step for optical fiber broadband to move from "popularization" to "ultimate experience", silently propelling our digital lives toward higher speeds and richer possibilities.

In the wave of digitalization, high-speed data transmission and processing have become the core driving forces behind technological development. As a key carrier of information transmission, optical communication technology continues to evolve to meet the explosive growth in bandwidth demand. Among these advancements, the LPO optical module has emerged with unique technological advantages, standing out as a breakthrough technology in the field of optical communication.
 

I. Definition of LPO Optical Module

 
LPO stands for Linear-drive Pluggable Optics. Its core features lie in the combination of linear drive technology and pluggable characteristics.

 

  • Pluggable characteristics: Similar to USB devices, it supports flexible plug-and-play, greatly improving the convenience of equipment installation, maintenance, and upgrades, while significantly reducing operational costs and downtime in scenarios such as data centers.
  • Linear drive technology: This is the core difference between LPO and traditional optical modules. Traditional optical modules rely on DSP (Digital Signal Processing) chips for signal processing, which suffer from high power consumption and high costs. In contrast, LPO optical modules abandon DSP chips and adopt linear analog technology to directly drive optoelectronic devices, simplifying the signal processing and optimizing energy efficiency.

 

II. Working Principle of LPO Optical Module

 
The core function of an LPO optical module is to realize efficient conversion between electrical and optical signals, with its working process centered on "simplified processing":

 

  • Transmitting end: After receiving an electrical signal, it is processed by a high-linearity Driver chip with CTLE (Continuous Time Linear Equalization) function to compensate for high-frequency attenuation during transmission. Then, the laser is directly driven to convert the electrical signal into an optical signal, which is sent through an optical fiber.
  • Receiving end: The optical detector converts the received optical signal into a weak electrical signal, which is amplified and equalized by a TIA (Transimpedance Amplifier) with EQ (Equalization) function. After restoring the signal integrity, it is transmitted to the terminal equipment.

 

The entire process replaces the traditionally complex DSP processing with simple signal compensation, significantly reducing power consumption and costs while ensuring transmission quality.

III. Technical Advantages of LPO Optical Module

 
Compared with traditional optical modules, the advantages of LPO are concentrated in three dimensions: "low consumption, low cost, and high efficiency":

 

  • Low power consumption: After removing the DSP chip, the power consumption of a 400G LPO module can be reduced to below 4W, which is about 50% lower than traditional solutions, directly reducing electricity bills and cooling costs in data centers.
  • Low cost: Eliminating the high-cost DSP chip reduces material costs by 15-20%. At the same time, the simplified structure also lowers manufacturing costs, laying the foundation for large-scale applications.
  • Low latency: By skipping the DSP processing link, the delay is reduced from the nanosecond level to the sub-nanosecond level, a reduction of more than 30%, perfectly meeting the strict real-time requirements of AI training, high-frequency trading, and other scenarios.
  • Compatibility and flexibility: It retains the traditional pluggable package, enabling seamless compatibility with existing network hardware. Moreover, it supports data rates from 100G to 800G and even higher, adapting to diverse scenario needs.

 

IV. Application Scenarios of LPO Optical Module

 
With its unique technical advantages, LPO optical modules show strong competitiveness in the following scenarios:

 

  • Data center internal interconnection: In short-distance scenarios of 100 meters to 2 kilometers, its low power consumption and low cost can efficiently meet the connection needs between servers and switches, improving the overall operational efficiency of data centers.
  • AI computing power clusters: The low-latency feature precisely matches the intensive communication patterns in AI training, ensuring fast data transmission in 10,000-card-level clusters, avoiding network bottlenecks, and enhancing the overall computing power performance of the cluster.

 

V. Challenges and Countermeasures of LPO Optical Module

 
Despite its significant advantages, LPO optical modules still need to overcome the following bottlenecks:

 

  • Transmission distance limitation: Due to the lack of DSP processing, the communication distance is limited, and it is currently mainly applicable to medium and short distances. Countermeasures include: adopting silicon photonics integration technology and advanced packaging processes to improve signal stability, and introducing intelligent compensation algorithms to optimize transmission performance.
  • High precision requirements for craftsmanship: Strict requirements for the matching accuracy of optical devices and circuit parameters necessitate enterprises to improve precision manufacturing capabilities and strengthen cooperation across the industrial chain to unify standards.
  • Standardization issues: The lack of unified industry standards affects the compatibility and interoperability of products from different manufacturers. Currently, industry associations and standardization organizations are accelerating the formulation of relevant technical specifications to promote industrialization.

 

VI. Future Development Trends of LPO Optical Module

 
With technological iteration, the development direction of LPO optical modules is gradually becoming clear:

 

  • Continuous technological innovation: Developing higher-performance optical devices, optimizing circuit design and compensation algorithms, and integrating emerging technologies such as AI to realize intelligent management and adaptive adjustment of modules.
  • Expansion of application fields: Extending from data centers and AI clusters to 5G communication, high-performance computing, intelligent transportation, and other fields, helping various industries achieve digital transformation.
  • Multi-technical collaboration: Forming complementary advantages with technologies such as CPO (Co-packaged Optics) and coherent optical communication to build full-scenario optical communication solutions covering short, medium, and long distances, meeting diversified transmission needs.

 

By simplifying technology to balance performance and cost, LPO optical modules are reshaping the technical landscape of the optical communication field. With the gradual resolution of existing challenges, they are expected to become the core solution for high-speed short-distance communication in the future, providing key support for the development of the digital economy.
 

In advanced electronic drive systems, precise frequency control is the foundation of reliable operation. Oscillator circuits generate the timing signals that govern switching actions in power electronics, synchronize digital control units, and maintain steady communication between components. Without accurate oscillator performance, even well-designed motor drive systems can suffer from instability, increased losses, or reduced efficiency.

 

As motor technologies evolve, the requirements placed on oscillators have become increasingly demanding. In electric vehicle (EV) drive motors, switching frequencies must remain consistent under rapidly changing load conditions. Robotics and servo applications depend on precise oscillation to achieve exact positioning. Unmanned aerial vehicles (UAVs) require stable timing sources to maintain responsive motor control during flight. Similarly, industrial frequency inverters rely on oscillator circuits to regulate high-power motors with minimal harmonic distortion.

                      oscillator frequency stability

The role of oscillators in motor drive systems

Motor control requires accurate timing signals to regulate voltage, current, and switching frequency. Even minor frequency drift can lead to inefficiencies, higher heat generation, or unstable operation. For example, in electric vehicle drive motors, the precise coordination between the inverter and motor ensures smooth torque delivery and higher energy efficiency. Oscillators serve as the backbone of this synchronization by providing stable clock references.

 

In robotics and servo motors, frequency stability directly affects positioning accuracy. Industrial robots executing repetitive tasks rely on synchronized control loops. A fluctuation in oscillator frequency may cause delays or errors, resulting in reduced precision. Similarly, servo systems that require microsecond-level accuracy depend on oscillators with low jitter and excellent temperature stability.

 

Crystal oscillators as the preferred solution

While various oscillator technologies exist, crystal oscillators are widely adopted in motor drive applications because of their superior stability. Quartz crystals exhibit a highly consistent resonance frequency, which is far less affected by temperature, vibration, or aging compared to LC oscillators or RC oscillators. This reliability makes them an essential component in demanding fields such as:

Unmanned aerial vehicle (UAV) motor control: where flight stability and navigation systems demand consistent timing references to avoid control instability.

Industrial frequency inverters: which regulate large motors in factories. These systems require oscillators that can operate accurately across wide temperature ranges while minimizing electromagnetic interference.

High-precision robotics: where every small deviation in frequency can influence servo accuracy and process efficiency.

 

Challenges to frequency stability

Despite their inherent advantages, oscillators can still face challenges in maintaining frequency stability under real-world conditions. Key factors include:

Temperature variations – Wide environmental ranges, especially in automotive and outdoor applications, can shift oscillator frequency.

Mechanical stress and vibration – In UAVs and EVs, constant vibration can degrade timing accuracy.

Aging effects – Over long operational periods, crystal parameters gradually change, which can affect resonance frequency.

Power supply noise – Fluctuations in supply voltage may induce jitter or frequency instability.

Addressing these challenges requires careful design considerations and advanced oscillator technologies.

Methods to improve oscillator frequency stability

Several techniques are employed to enhance stability and ensure reliable motor drive performance:

Temperature-compensated crystal oscillators (TCXO): By integrating temperature sensors and compensation circuits, TCXOs minimize frequency drift across broad thermal ranges, making them suitable for EV inverters and outdoor robotics.

Vibration-resistant packaging: Specialized oscillator housings reduce sensitivity to mechanical shocks, enhancing reliability in UAVs and industrial machinery.

Low-jitter differential oscillators: Essential for servo control systems, these oscillators provide clean timing signals that support precise motion control.

Redundant oscillator designs: In safety-critical systems such as autonomous vehicles, dual or redundant oscillators ensure continuous operation even in case of failure.

 

Application case studies

  •       In new energy vehicle drive motors, crystal oscillators ensure consistent inverter switching, allowing maximum energy conversion efficiency and extending battery life.
  •       In robotics, they enable stable synchronization of multiple servo axes, resulting in smoother motion and higher productivity.
  •       In UAV motor control, frequency stability supports rapid flight adjustments, enabling drones to maintain stable navigation even in turbulent environments.
  •       In industrial variable-frequency drives, oscillators stabilize switching frequencies, reducing harmonic distortion and improving overall system efficiency.

 

Improving frequency stability in oscillator circuits is not simply a matter of enhancing component specifications; it is about enabling reliable, precise, and energy-efficient operation across diverse high-performance applications. From electric vehicles to industrial robotics and UAVs, crystal oscillators form the timing foundation that makes advanced motor control possible. As industries continue to demand higher precision and efficiency, further innovation in oscillator design—especially in temperature compensation, vibration resistance, and low-jitter performance—will remain essential to advancing the capabilities of modern electronic systems.

A defining feature of the IsoClad 917 material is its innovative non-woven reinforcement structure. Unlike traditional woven glass substrates, this unique architecture, comprised of longer random fibers and created through a proprietary manufacturing process, grants the laminate remarkable dimensional stability and unparalleled uniformity of dielectric constant across the board. This consistency is critical for maintaining impedance control and preventing signal degradation in sensitive high-frequency designs. Furthermore, this construction makes the final PCB assemblies surprisingly pliable, suitable for applications where the board must be bent or formed, such as in conformal or wrap-around antenna systems.

 

Detailed Electrical Characteristic


IsoClad 917 PCB features

 

The IsoClad 917 PCB exhibits a exceptionally stable dielectric constant of either 2.17 or 2.20, with an impressively tight tolerance of±0.03 when measured at 10 GHz. This precision allows designers to achieve accurate impedance matching and predictable circuit behavior.

 

Complementing its stable Dk is an ultralow dissipation factor of just 0.0013 at the same 10 GHz benchmark. This remarkably low loss tangent ensures minimal signal attenuation, preserving signal integrity and enhancing overall system efficiency, which is crucial for power-sensitive applications like radar and communications infrastructure.

 

Adding to its reliability, IsoClad 917 demonstrates highly isotropic behavior across its X, Y, and Z axes.

What Makes Kappa 438 High Frequency PCB a Superior Alternative to Standard FR-4 Materials?


In today’s rapidly evolving wireless landscape, the surge in data consumption and the rollout of next-generation networks demand circuit materials that deliver enhanced RF performance, reliability, and signal integrity. Traditional FR-4 substrates, while cost-effective, often fall short in meeting these stringent requirements. This is where Rogers Corporation’s Kappa 438 high-frequency PCB material stands out—a purpose-engineered laminate designed to bridge the gap between standard epoxy-glass materials and high-performance RF substrates.


Originally developed to address the escalating needs of the wireless industry, Rogers Kappa 438 offers a unique combination of superior dielectric properties, reduced signal loss, and exceptional thermal stability. Its innovative formulation uses a glass-reinforced hydrocarbon ceramic system that not only enhances high-frequency performance but also allows for cost-efficient fabrication using standard FR-4 manufacturing processes. This means designers can achieve elevated electrical performance without completely overhauling their existing production setups.


Key Features of Kappa 438 Laminates


Key Features of Kappa 438 Laminates


One of the most critical attributes of Kappa 438 is its consistent dielectric constant (Dk) of 4.38 at 2.5 GHz. This value aligns closely with common FR-4 standards, enabling seamless integration into designs that require better RF characteristics without drastic impedance mismatches or redesign efforts.


Moreover, Kappa 438 PCB provides tighter tolerances on both Dk and thickness compared to conventional FR-4. This allows for more accurate impedance control, minimizes signal distortion, and improves overall signal integrity—a crucial advantage in high-speed digital and RF circuits.


The material also exhibits a low coefficient of thermal expansion (CTE) across all axes: 13 ppm/°C in the X direction, 16 ppm/°C in Y, and 42 ppm/°C in Z. This dimensional stability under temperature fluctuations ensures greater reliability of plated through-holes and reduces the risk of failure in thermal cycling scenarios.


With a high glass transition temperature (Tg) exceeding 280°C (as measured by TMA), Kappa 438 performs reliably in high-temperature environments, making it suitable for lead-free soldering processes and applications exposed to thermal stress. Furthermore, it complies with UL 94-V0 flammability standards, adding an extra layer of safety for use in critical electronic systems.
