The 4CH Compact CWDM MUX DEMUX Combo (CCWDM Multiplexer/Demultiplexer Combo) adopts an innovative design. For adjacent channel processing, it realizes cascaded transmission in free space using parallel light beams. This design breaks the structural limitations of traditional multiplexer/demultiplexer equipment, effectively reducing interference and loss during light beam transmission. It allows signals of different channels to be stably transmitted in independent spatial paths, which not only improves the accuracy of signal transmission but also simplifies the internal structure of the equipment. This lays a foundation for subsequent miniaturized packaging and cost control, meeting the demand for efficient signal processing in fiber optic communication systems.

During the manufacturing process of this multiplexer/demultiplexer combo, high-quality optical materials and precision electronic components are selected. The core optical lenses are made of high-light-transmittance quartz material, which reduces the refraction loss of optical signals. The internal circuit components are industrial-grade temperature-resistant parts, which can adapt to temperature fluctuations in complex environments. At the same time, the equipment shell is made of corrosion-resistant and impact-resistant alloy material. This not only improves the physical protection capability of the equipment but also effectively shields external electromagnetic interference. From the material perspective, it ensures the long-term operation stability and reliability of the product and reduces the later maintenance cost.
The equipment incorporates the concept of energy-saving design. By optimizing the internal optical path structure and circuit power consumption control, it reduces the overall energy consumption while focusing on ensuring the consistency of signals in each channel. The built-in signal equalization module can adjust the optical power and wavelength stability of each channel in real time, avoiding transmission errors caused by signal differences between channels. Even under long-term high-load operation, the attenuation amplitude and phase shift of signals in each channel can still be kept within an extremely small range, providing strong support for the stable transmission of fiber optic communication systems.
This multiplexer/demultiplexer combo has excellent compatibility and can support the integration of various network devices and systems. Whether it is SDH/SDN equipment in the telecommunications field, servers and storage arrays in data centers, or switches and routers in enterprise campus networks, all can be seamlessly connected to this equipment through standard interfaces. In addition, its compact design is suitable for cabinet installation of different specifications, enabling flexible integration into the existing fiber optic communication architecture. It can improve the network bandwidth utilization without large-scale transformation, providing users with a cost-effective system upgrade solution.
Lower insertion loss makes CCWDM module have lower signaattenuation in operation, thus reducing the power requirement ofsignal transmitter.
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.
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.
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.
