FUSED FIBER COUPLERS/WDM COUPLERS
The single-mode broadband and narrowband fused fiber couplers are compact monolithic bidirectional multiport devices for splitting or combining light. Coupling ratios from 1% to 50% are available. Also available are fused fiber wavelength-division multiplexers that combine or separate light at 980, 1310, 1480, and 1550 nm. All couplers are designed to Bellcore standards.
