What is Filter WDM Module?

LFO Filter WDM module is based on Thin Film Filter (TFF) technology. Our Filter-Based WDM product family covers following wavelength windows commonly used in optical fiber systems: 1310/1550nm (for WDM or DWDM optical communications), 1480/1550nm (for high-power DWDM optical amplifier/EDFA), 1510/1550nm (for DWDM multi-channel optical networks) and 980/1550nm (for high performance DWDM optical amplifier/EDFA) and 1310/1490/1550nm (for PON/FTTX/test instrument) .

Triplexer Filter WDM Module

1. PON Filter WDM Module
1310/1490/1550nm filter WDM module used single fiber triple operation wavelength transmission technology, the 1550nm wavelength is used for downstream analog CATV, the 1310nm wavelength is used for the upstream transmission to a large number of end users, the 1490nm wavelength is use for digital downstream transmission.

2. Network Test and monitor Filter WDM Module
1310/1550/1625nm (1310/1550/1650nm) filter WDM Module enables non-intrusive testing of any fiber path on a Remote Fiber Test System. This capability is ideal for testing active fibers in service.

3. 1310/1490/1550/1625nm Filter WDM Module
1310/1490/1550/1625nm FilterWDM Module is used to combine or separate 1625nm channel with three triplex wavelength 1310nm, 1490nm and 1550nm. Using this device, 1625nm channel can be added into the existing triplex FTTH system.
