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
