Optical isolator

Features Minimize Feedback into Optical Systems Operating Ranges of 1290 - 1330 nm, 1530 - 1570 nm, 1540 - 1560 nm, or 1990 - 2010 nm At Least 0.8 m of Panda-Style PM Fiber on Both Sides Available with 2.0 mm Narrow Key FC/APC Connectors or Bare Ends Designed for CW Applications Each Unit is Individually Tested Custom Isolators Available (See Custom Isolators Tab) Fiber isolators protect light sources from back reflections and signals that can cause intensity noise and optical damage. Optical isolators, also known as Faraday isolators, are magneto-optic devices that preferentially transmit light in the forward direction while absorbing or displacing light propagating in the reverse direction (see the schematic below). Please see the Isolator Tutorial tab for an explanation of the operating principles of a Faraday isolator.
