‌1. Ultra-Low Insertion Loss: <2.0dB for 18-Channel Configuration‌
Utilizing precision Thin-Film Filter (TFF) technology, the 18-channel system maintains insertion loss below 2.0dB, reducing optical power consumption by 30% compared to conventional solutions. The optimized optical path ensures bit error rates below 10^-12 over 40km transmission while significantly extending optical module lifespan.

‌3. Superior Mechanical Stability‌
The all-metal sealed housing passes MIL-STD-883G 2000G shock tests and 5G vibration tests. Its stress-relief structure maintains <0.1dB performance fluctuation after 1000 plugging cycles, ideal for harsh environments like vehicles and marine applications.

‌4. Data Center Interconnect Solutions‌
Supports multi-rate transmission (10G/25G/40G/100G) with 18 wavelength channels per fiber. Hot-swappable design enables 1:18 port multiplexing, reducing fiber usage by 80% versus point-to-point solutions.

‌5. Cost Advantage: Vertical Integration‌
HJY's end-to-end production from wafer processing to packaging achieves 90% self-sufficiency for optical components. Mass production reduces costs by 18% - e.g., 16-channel systems priced at 82% of market rates.

Unique Free-Space Technology

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.
