Description
CWDM 器件
F-toneNetworks’s Coarse Wavelength Division Multiplexer (CWDM) devices demonstrate low loss and reliable performances.
These devices show broad passband and high isolation, making them ideal for operation with inexpensive, uncooled lasers. They are low cost products for the CATV and metro/access markets.
Easily customizable, F-toneNetworks’s CWDMs can be configured from a standard list of packaging and connector options
Features
● Low insertion loss
● High channel isolation
● Low polarization dependent loss
● Exceptional reliability and stability
Applications
● Access networks
● Metro WDM systems
● Enterprise network
