Fiber Optic Isolator, Enhanced, 50 dB, 1550 nm, Bare Fiber Pigtails.

The ISS-1550 enhanced model features extremely low polarization mode dispersion and stable performance over a wide wavelength and temperature range. The standard version comes with bare fiber. Use option code 20 when ordering connectorized versions. Newport’s Fiber Optic Isolators are passive, fiber-pigtailed devices that reduce back reflections and backscattering of light (highly desirable in laser applications, for example).

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.

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.

Epoxy-free Optical Path

By utilizing an epoxy-free optical path, our fiber optic isolators exhibit increased isolation performance, stability and long-term reliability

Applications

Fiber optic amplifiers
Fiber optic ring lasers
High-speed and coherent fiber optic communication systems
Fiber optic links in CATV applications
Fiber optic gyro systems
Laser diode integrated optic modulator interfaces
Instrumentation and testing applications
