Compact CCWDM MUX DEMUX 4 or 8 Channel 1270 to 1610nm CWDM Passive Optical Network Component RoHS Compliant

1. Ultra-Compact Form Factor: 28x22.5x6.5mm Space-Saving Design
   Featuring chip-scale integrated packaging technology, this device reduces volume to 1/4 of traditional components (28x22.5x6.5mm), saving 80% installation space for optical modules. Its compact design is ideal for high-density data center racks, significantly improving thermal management while enabling parallel deployment of up to 16 ports within a 1U space.

3. Multi-Rate Hybrid Multiplexing: 1G-200G Full-service Support
   With wavelength-adaptive technology, a single port simultaneously carries 1G/10G/25G/40G/100G/200G Ethernet, SAN storage networks, OTN optical transport, and legacy SDH/SONET services. Its flexible wavelength allocation enables hybrid transmission of video surveillance and data services, making it ideal for 5G fronthaul and backhaul convergence scenarios.

4. Structural Innovation: 75% Volume Reduction
   Compared to 2D free-space optical designs, this 3D integrated optical path stacks waveguides and filters vertically. Maintaining identical channel count while reducing volume by 75%, it also achieves 40% lower insertion loss and enhanced mechanical stability with performance fluctuations <0.1dB under vibration.

5. Cost Advantage: Vertically Integrated Supply Chain
   HJY achieves end-to-end production from wafer dicing to device packaging, with 90% self-sufficiency for key optical components. Mass-produced laser chips and filters reduce total costs by 18% compared to industry standards. For example, an 8-channel system retails at just 82% of competitors' prices, making it perfect for large-scale PON network deployments.

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.

Insertion Loss <2.6 dB

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.
