TECHNICAL DATASHEET

Mini Size PM Optical Isolator + WDM 2-in-1 Hybrid

Miniature 2-in-1 hybrid integrating a PM optical isolator and a WDM filter in a compact dia. 3.2 x 30 mm package. Combines pump light (980 nm or 1480 nm) into the signal path (1550 nm) while providing robust reverse isolation to protect upstream seed lasers from amplified spontaneous emission (ASE) and back-reflections.
