Product Description

LGX Box FWDM Filter for 1310/1550/1650nm Wavelengths

This LGX Box FWDM Filter combines two FWDM filters with spliced reference legs to bypass 1650nm wavelengths. Designed for robust performance in network upgrades, this Filter Wavelength Division Multiplexer (FWDM) utilizes Thin Film Filter (TFF) technology for reliable operation in demanding optical network environments.

Product Overview

FTTX Filter WDM modules are extensively used in EDFA, Raman amplifiers, WDM networks, and fiber optics instrumentation. The device combines or separates light at different wavelengths across a wide range, expanding single fiber capacity for bi-directional communication. Ideal for optical network upgrades, expansion, and introducing comprehensive new business applications.

Application Diagram

The Filter WDM system employs a Multiplexer at the transmitter to combine multiple wavelengths (each carrying different signals up to 10G bite-rate) and a demultiplexer at the receiver to separate them. With low insertion loss, minimal polarization dependence, and high isolation, this filter is widely used in CATV systems, FTTx and PON systems, fiber communication networks, and test instrumentation.
