4 Channel Compact CWDM MUX CCWDM Multiplexer for 10G or 25G Networks, Compact Size Saving Space

The 4 Channel Compact CWDM MUX (4-Channel Compact CWDM Multiplexer) is specially designed for 10G or 25G networks, with its core advantages focusing on size and loss control. It features an ultra-small size and adopts a unique integrated structural design, allowing it to be easily embedded in network cabinets or equipment enclosures with limited space. Meanwhile, it has excellent low insertion loss performance, with a typical insertion loss as low as 0.8dB, which greatly reduces the energy attenuation of high-speed signals during transmission. This ensures the stable transmission of 10G/25G signals and perfectly meets the dual requirements of high-speed networks for signal quality and space utilization.

This multiplexer has strong compatibility and can realize hybrid deployment with other brands of CWDM (Coarse Wavelength Division Multiplexing), DWDM (Dense Wavelength Division Multiplexing), LANWDM (Local Area Network Wavelength Division Multiplexing) and other equipment. There is no need to worry about adaptation issues caused by brand or type differences. Whether adding new equipment during the upgrade of existing networks or building a cross-brand hybrid wavelength division multiplexing system, it can achieve seamless connection. This greatly improves the flexibility of network construction and reduces the cost of equipment replacement and system reconstruction.

The equipment integrates the concept of energy-saving design, and the most intuitive manifestation is that no complex wiring is required. Its simplified interface layout and integrated structure reduce the redundant cables needed by traditional equipment. This not only lowers the difficulty of wiring during installation and shortens the construction time, but also reduces the additional energy consumption and signal interference caused by cables. At the same time, it cuts down the costs of cable procurement, laying and later maintenance, realizing the triple value of "cost reduction + energy saving + high efficiency".

The product adopts a lightweight design, with a weight of ≤150g, and the overall body is thin, light and compact. In practical applications, whether it is a single person installing and fixing in the cabinet, or disassembling, handling or adjusting the position of the equipment in the later stage, there is no need to use additional heavy tools, and the operation is convenient and labor-saving. This feature is especially suitable for scenarios such as data centers and base stations that require frequent adjustment of equipment layout, effectively improving the efficiency of installation and operation and maintenance, and reducing the input of labor costs.

• 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.

*Above specification are for device without connector.

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.

The compact CWDM is ultra low loss, super thermal stability, and excellent reliability, with smaller size compact design to save much space in the application. Applicable to CWDM system and optional special service

Compact coarse wavelength division multiplexers (CCWDM Mux) is the mini version of CWDM Mux. Compared with traditional CWDM technology, CCWDM technology uses free-space optics platform which can significantly improve optical performance, in a package less than 1/4 the size of conventional CWDM modules. Main advantages of CCWDM Mux are high wavelength accuracy and stability, low insertion loss, high isolation and low PDL(polarization dependent loss). It's protocol and rates transparent supporting such applications as the CWDM system, PON networks, and CATV Links.
