8 Hannel Demux 100GHz Grid DWDM Module

Based on thin-film filter (TFF) technology, the module provides a completely passive DWDM demultiplexing function, which can transmit 8 channels (C21–C28) strictly allocated in accordance with the ITU‑T G.694.1 standard on a coaxial fiber pair, with a channel spacing of 100GHz (about 0.8nm), no additional power supply is required, and the reliability is high (MTBF≈500 years), which is suitable for building high-density, low-power long-distance optical networks. The module is an FMU plug-in design that supports installation in a standard 2-slot 1U rack chassis, equipped with LC/UPC connectors, monitoring ports, expansion ports, and 1310nm bypass ports to meet future bandwidth expansion needs.

Fully Passive Design
Utilizes Thin-Film Filter (TFF) technology to operate without external power, enhancing system reliability and reducing O&M costs.

High‑Density 8‑Channel Demultiplexing
Precisely follows ITU‑T G.694.1 for channels C21–C28 with 100 GHz (≈0.8 nm) spacing to meet high‑density WDM requirements.

Ultra‑Low Insertion Loss
≤ 3.7 dB for main channels and ≤ 3.4 dB for expansion ports, minimizing link loss and ensuring extended reach.

Superior Channel Isolation
≥ 30 dB for adjacent channels, ≥ 40 dB for non‑adjacent channels, and ≥ 15 dB for expansion ports to suppress crosstalk.

Excellent Return Loss & Directivity
Return loss ≥ 45 dB and directivity ≥ 50 dB to maintain signal integrity and reduce reflection interference.

Wide Operating Temperature Range
–40 °C to +85 °C for reliable performance in both indoor and outdoor deployments.

Compact, Rack‑Mountable & Scalable
19″ 1U FMU pluggable module for standard 2‑slot chassis; expansion ports allow easy cascading for capacity growth.

High Reliability & Long Life
MTBF ≥ 500 years, compliant with Telcordia GR1221/GR1209, CE, RoHS, FCC, ensuring stable long‑term operation.

Versatile Bypass/Monitoring Port
1310 nm monitoring/bypass port for real‑time signal verification or traffic bypass-simplifying network maintenance.
