CWDM Modules

Name: CWDM Modules
Brand: Lfiber Optic Limited
Availability: InStock

Description

CWDM Modules (fiber optical multiplexer/demultiplexer) systems are considered as a cheaper and simpler alternative to DWDM systems for metro access network applications. Since CWDM Modules systems have wide channel spacing (20 nm), they do not require precise wavelength control for transmitter lasers. Thus, cost-effective non-cooled lasers as well as lower-cost passive components may be used for CWDM Mux or Demux systems. Lfiber supplies a variety of WDM devices and are promoting higher speed and more reliable optical network.
