780-1550nm PM Filter Coupler Module (1xN / MxN)
Modular polarization-maintaining filter coupler packaging multiple 1x2 or 2x2 PM filter units into an integrated ruggedized aluminum enclosure. Designed for multi-channel power splitting and monitoring across 780nm, 850nm, 980nm, 1064nm, 1310nm, and 1550nm with high extinction ratio (>20 dB) and superior thermal stability.
Technical Specifications
Values are specified without connectors. With connectors, IL increases by 0.3 dB, RL decreases by 5 dB and ER decreases by 2 dB. Custom channel counts and splitting ratios subject to engineering confirmation.
Configuration and ordering notes
Configuration parameters include input/output port counts (e.g. 1x4, 1x8), operating wavelength, and whether tap ports require equal splitting or asymmetric monitoring ratios (e.g. 1% or 5%).
Key Applications
Multi-channel fiber optic gyroscopes (FOG); Coherent optical testing; Distributed fiber sensing arrays; Biomedical photonics.
