FWDM 1310nm 1490nm 1550nm optical filter
1. Description:
Three-port WDM specifically refers to three specific wavelength
division multiplexing devices. In fiber-optic communications
network, using three-port WDM can achieve two-way transmission of
voice, video, data, the three most common wavelengths of WDM are
1310&1490 & 1550nm. Three-port WDM filters use principle of
mutual collimator after binding the package, you can customize any
of three wavelengths. Such devices generally require 24 hours of
high temperature cycling and drop test to ensure products’
stability and reliability.
2.Features:
•Wide Wavelength Range
•Low Insertion Loss
•High Channel Isolation
•High stability and reliability
3.Application:
•System Monitoring
•WDM system
•Transmitters and Fiber
•Fiber optical amplifier
•Fiber optic lnstruments
