Optical isolators are vital devices for eliminating the undesirable effect of return beams in high-speed optical fiber transmittance routes and amplifiers. Optical isolation also protects your equipment from dangerous ground loops, spikes and surges.

Conoptics Model 715-I Polarization Independent Optical Isolator
The Model 715-I is designed to work with unpolarized or randomly polarized lasers. The product replaces the conventional Glan polarizer’s with calcite displacers at the input and output of the Faraday Rotator Assembly. Calcite crystals, when properly orientated, will generate two parallel beams with orthogonal polarizations.
The input calcite displacer splits the incident beam into two linear polarized beams. The separation of the two beams is determined by the length of the calcite displacer, and is designed to pass through the Faraday Rod.
The output calcite displacer recombines the two beams into one randomly polarized beam.
Conoptics offers two versions of the 715-I Optical Isolator.
Option 2: The non-tunable 2.1mm aperture Model 715-I.
