2024年11月4日 · CWDM与DWDM都是用多个不同的波长在同一根光纤中承载业务。 CWDM以扩大波长间隔，减少波长数量作为代价，从而大大降低了对激光器波长稳定性的要求，可以采用无制冷激光器作为光源（允许激光器的波长随温度变化，在波道内自由漂移），分波器的通道带宽也 ...

The built-in CWDM Multiplexing or De-multiplexing the 5-way optic, and transmit via one single fiber, which can transmit four-way SAT-IF signal of VL, VH, HL HH four polarizations and one-way CATV signal in one satellite with a high quality, flexible to install and convenient to use.

CWDM ITU-T standard wavelength Product overview Parameter Size chart Download Product overview Features: *Wide operating wavelength range *Low insertion loss *Ultra flat broadband *High channel isolation *High stability and reliability *Light path without epoxy resin Application: *WDM system *Cable TV system *FTTH 3-in-1 system Parameter ...

The standard type has 8 channels, mainly used in metropolitan network and access network for multiplexing/de-multiplexing. Low insertion loss. High channel isolation. Low Polarization …

Each channel carries data independently from each other, allowing network designers to transport different data rates. It’s protocol and rate transparent supporting such applications as 1G/10G Ethernet, SDH/SONET and 8/4/2/1G Fiber Channel across the same fiber link.

The CWDM module features wide channel bandwidth (13nm). Its isolation is greater than 30dB for adjacent channels,and greater than 40dB for non-adjacent channels. The module also has high thermal stability to ensure reliable performance under different environment. Features. Low Insertion Loss. High Isolation. Low PDL. Compact Design.
