CWDM Mux / DeMux Module

CWDM multiplexer / demultiplexer modules for cost-effective wavelength expansion.

Four form factors: ABS Compact Module (two sizes), 1U Rack Equipment, and LGX Module
Supports 4, 8, and 16 channel configurations across the CWDM grid from 1270 nm to 1610 nm
Low insertion loss: ≤1.6 dB (4ch), ≤2.8 dB (8ch), ≤4.5 dB (16ch) for ABS Compact Module
High adjacent channel isolation >30 dB; non-adjacent channel isolation >40 dB
Low passband ripple ≤0.40 dB and polarization dependent loss <0.30 dB across all variants
Return loss >45 dB and directivity >50 dB for excellent signal integrity
