Industrial temperature CWDM module supplier,High isolation CWDM compact module

1. Product Introduction

This 1-to-4 wavelength division multiplexer (4CH WDM module) is designed for harsh environments and high-reliability optical communication requirements, supporting efficient multiplexing and demultiplexing of four center wavelengths: 1271nm, 1291nm, 1311nm, and 1331nm.

2. Product Features

4-channel wavelength division multiplexing, operating wavelengths covering 1271/1291/1311/1331nm

Industrial-grade ultra-wide operating and storage range (-55℃ to 85℃)

Low insertion loss (≤1.5dB) and excellent isolation between adjacent/non-adjacent channels (≥30dB/≥40dB)

Fiber optic cable protected by 2.0mm armored sheath, providing excellent physical protection

Ultra-compact module design (37.5×12.8×6.5mm)

Hybrid connector configuration (COM port ST/UPC, other ports LC/UPC)

100% passed insertion loss and isolation tests in three temperature zones: -55℃/25℃/85℃

3. Application Scope

Special optical communication systems for harsh environments (extreme cold/extreme heat and damage-resistant applications).

Multi-service video surveillance and sensor networks (e.g., single-fiber multiplexing transmission of visible light, infrared, and image signals)

Industrial-grade automation control and fiber optic access networks

CWDM network node expansion and optical path interconnection systems
