8+1 CH Compact CCWDM MUX Module 1471-1611nm 1310nm Upgrade Port Free-Space CWDM Multiplexer SC APC
8+1 Channel Compact CCWDM MUX Module – Free-Space CWDM Multiplexer
The Huajiayu HJY 8+1 channel Compact Coarse Wavelength Division Multiplexer (CCWDM) is a high-performance passive optical module built on a free-space optics platform. Inside the device, adjacent signal channels are cascaded by parallel beams instead of fibers, which delivers ultra-low insertion loss, excellent channel isolation, and a remarkably compact aluminum housing less than one quarter the size of a conventional CWDM module.
This 8+1 channel CCWDM multiplexes eight CWDM channels on the ITU-T G.694.2 20 nm grid (1471–1611 nm) plus one independent 1310 nm upgrade port, making it an ideal choice for adding wavelength capacity to metro, access, broadband and data center networks while saving valuable rack space.
Key Features
- Ultra-low insertion loss ≤1.25 dB and low polarization dependent loss ≤0.2 dB
- Highly compact footprint – package dimensions only L44 * W25 * H6 mm
- Ultra stable and highly reliable free-space optical design
- Extended operating temperature range –40 to +85 °C
- Excellent channel isolation: ≥35 dB adjacent, ≥45 dB non-adjacent
- Polarization insensitive and protocol / data-rate transparent
Typical Applications
- Optical Add/Drop Multiplexing (OADM)
- Telecom backbone networks
- Metro and access networks
- Broadband and CATV networks
- Data center interconnect (DCI)
- Passive optical LAN (POL)
