Industrial Grade 4CH Compact CWDM MUX CCWDM Multiplexer, High Reliability for Fiber Optic Links

The Industrial Grade 4CH Compact CWDM MUX (Industrial-Grade 4-Channel Compact CWDM Multiplexer) excels in controlling signal transmission loss, with a typical insertion loss as low as 0.8dB. Low insertion loss means that when signals pass through the multiplexer, the amplitude of energy attenuation is extremely small, which can effectively reduce signal distortion and attenuation during transmission. This ensures that signals maintain high quality from the input end to the output end, providing solid support for long-distance and high-stability signal transmission in fiber optic links, and is particularly suitable for industrial communication scenarios sensitive to signal loss.

As an industrial-grade device, this multiplexer has excellent environmental temperature adaptability and can operate stably within a wide temperature range of -40℃~85℃. Whether in cold outdoor communication base stations or high-temperature industrial workshops, the device can effectively resist the impact of extreme temperature changes, avoiding performance degradation or shutdown due to temperature fluctuations. This strong environmental adaptability allows it to easily cope with diverse and complex working environments in industrial scenarios, ensuring the continuous smoothness of fiber optic links.

The device integrates the concept of energy-saving design, and one of its core advantages is extremely low transmission loss—the typical transmission loss of the 4-channel CCWDM MUX is ≤1.6dB. Low transmission loss not only reduces the ineffective consumption of signal energy and lowers the additional energy consumption during device operation, in line with the industrial development trend of green energy conservation, but also further reduces the cumulative loss of signals in multi-channel transmission. This ensures that signals in each channel can maintain stable transmission efficiency, improving the energy utilization rate and operational economy of the overall fiber optic link.

This industrial-grade CWDM multiplexer has excellent support capabilities for high-speed signal transmission and can adapt to a variety of high-speed communication protocols and signal types. Whether it is 10Gbps Ethernet signals or traditional high-speed transmission signals such as SDH/SONET, the device can achieve stable multiplexing and transmission. Even in high-speed transmission scenarios, it can still maintain low loss and low interference performance. This feature enables it to meet the transmission needs of high-speed data such as high-definition monitoring data and real-time control signals in the industrial field, providing strong support for the high-speed upgrade of industrial fiber optic communication systems.

• Lower insertion Loss

  Lower insertion loss makes CCWDM module have lower signaattenuation in operation, thus reducing the power requirement ofsignal transmitter.

• High lsolation

  The higher isolation value enables sufficient signal isolation duringmulti-signal transmission in the CcWDM module, effectivelypreventing crosstalk between signals and causing distortion of thetransmission signal.

• Mature Production Process

  The CCWDM module of HJY has mature production technology,stable and reliable performance, supports the work in the harshenvironment of -40~+85 'C,and ensures the stable transmissionof signals.

The CCWDM Mux adopts Free-Space technology, which uses light propagating in free space to wirelessly transmit data. Inside the device, adjacent signal channels are cascaded by parallel beam instead of the fiber. This saves a lot of space for package box, and the unique workmanship also helps CCWDM Mux Demux with low insertion loss.

The insertion loss of CCWDM Mux is about half of the conventional CWDM Mux. This reduces the overall loss of the whole link, and leaves more choices for the design of the solution.

CCWDM Mux uses the parallel beam for cascading instead of the fiber, which saves significant space. The minimum dimension of CCWDM aluminum box module is less than the 1/4 size of minimum CWDM ABS pigtailed module.

1. Telecommunications Applications
   • Fiber Optic System Capacity Boost: CCWDM modules in fiber optic networks multiplex diverse wavelength optical signals into one fiber. In metro network access, operators use them to combine users' signals like Ethernet and voice onto different wavelength carriers in one fiber, enhancing fiber utilization and cutting new fiber installation costs.
   • Long-Distance Transmission Aid: In long-haul links, while DWDM leads in high-capacity, CCWDM serves auxiliary roles. It transmits monitoring, backup data with lower bandwidth needs cost-effectively.
2. CATV Network Use
   • Program Transmission Expansion: In CATV headends, CCWDM modules modulate multiple TV channel signals to different wavelengths for fiber transmission to sub-headends or users. Operators adding HD channels can use it to expand capacity by multiplexing new and old signals.
3. Data Center Interconnection Role
   • Connecting Different Data Centers: As data center scale and number grow, CCWDM modules interconnect them. They multiplex internal network signals like server data and storage backups via fiber, improving connection efficiency, bandwidth use, and reducing costs. In cloud service providers' data center interconnections, it enables high-speed data transfer.
