- Fiber Optic Isolator Dual Stage 1550nm Single Mode or PM

Description

Single Mode Fiber Isolator

CSRAYZER’S Single Mode Fiber Isolator SMI Series Products, are in-line fiber micro-optic components, which allows light to transmit only in the forward direction while blocking the backward transmission. It is widely used for fiber laser, fiber amplifier, fiber communication and fiber sensor, with features of high isolation, Low PDL and low insertion loss.
