1×2 PM1550 DWDM Polarization Maintaining DWDM Device

1. Product Introduction

The 1×2 Polarization Maintaining Dense Wavelength Division Multiplexer (PM DWDM) is a self-developed polarization-maintaining passive optical device from Gezhi Photonics. Designed in strict accordance with ITU standard wavelength grid, it adopts precision optical coating and polarization-maintaining fiber coupling technology to realize splitting/combining of single-channel optical signals while fully preserving the polarization state of incident light.

Featuring low insertion loss, high return loss, high extinction ratio and excellent thermal drift stability, the component supports three standard ITU channel spacings: 50GHz, 100GHz and 200GHz. It handles continuous wave power from 0.3W to 5W, with customized heat sink packaging available for high-power applications over 10W. Widely deployed in polarization-sensitive optical communication systems including CATV transmission, backbone WDM systems and EPON/GPON optical access networks.

2. Key Features & Typical Applications

Key Features	Typical Applications
Low Insertion Loss	CATV Optical Transmission Systems
High Return Loss	Backbone Dense WDM Transmission Systems
High Extinction Ratio	EPON / GPON Passive Optical Access Networks
Excellent thermal stability for both wavelength and insertion loss	Precision optical test systems requiring stable polarization
Multiple channel spacing options: 50GHz / 100GHz / 200GHz	Precision optical test systems requiring stable polarization
Multiple CW power handling grades; heat sink package for high-power use	Continuous & pulsed laser beam splitting/combining for industrial high-power scenarios
Compact standard metal package: Φ5.5×35mm, easy for system integration
Customizable pigtail, fiber length and fiber connectors; 1×N PM DWDM modules available on request
