Overview

Our fiber pigtailed isolators are passive, fiber-pigtailed devices that reduce back reflections in optical fibers and backscattering of light which is highly desirable in many laser applications.

Very low insertion loss, high isolation and high return loss
Minimal polarization dependent loss
Low polarization mode dispersion
Epoxy-free optical path
Compact lightweight assembly

Features

Standard Pigtailed Isolators

The standard ISC model isolator features typical peak isolation of >40 dB and very low polarization mode dispersion.

Enhanced Pigtailed Isolators

The enhanced ISS model isolators feature extremely low polarization mode dispersion and stable performance over a wide wavelength and temperature range with peak isolation greater than 50 dB.

Supreme Pigtailed Isolators

The supreme ISU model isolators feature extremely low polarization mode dispersion and stable performance over a wide wavelength and temperature range with peak isolation greater than 60 dB.

Compact Lightweight Assembly

Our fiber optic isolators are designed into a compact, lightweight assembly which allows easy integration in small laboratory, field, and system applications.
