Product Description

1x2 Polarization Maintaining Filter Wavelength Division Multiplexer For CATV System

Product Overview

The polarization maintaining filter WDM series provides wavelength division multiplexing while maintaining signal polarization. The PM FWDM is based on environmentally stable thin film filters technology and is characterized with high extinction ratio, low insertion loss, and high return loss. They are ideal for high speed WDM network systems.

Applications

CATV System
CWDM/DWDM Module
EPON/GPON Networks

Features

Low Insertion Loss
High Return Loss
High Reliability & Stability
