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.
Notes:
- Above data are test results without connectors. The insertion loss of one pair of connector is less than 0.3 dB.
- These CWDM Modules (fiber optical multiplexer/demultiplexer) modules & devices are customizable and subject to change without notice.
- For product customization or special requirement, please contact our sales representative.
