Polarization-Maintaining Fiber Optical Circulator

Name: Polarization-Maintaining Fiber Optical Circulator
Brand: Lfiber Optic Limited
Availability: InStock

Description

LFIBER's polarization maintaining optical circulator with high extinction ratio is a passive component based on the Faraday effect, transmitting light signals from one port to the next sequential port with low loss, but at the same time blocking any light transmission to the previous port.

By using polarization maintaining fiber (PMF), it is able to maintain the same state of polarization (SOP) of the light signals. The 3-port polarization maintaining optical circulator (high extinction ratio) can work on both slow-axis and fast-axis linear polarizations, or just transmit one principal polarization state in only one direction and block the orthogonal state in both directions.

Features

Low Insertion Loss

High Isolation & Extinction Ratio

High Reliability & Stability

Notes:

High extinction ratio greater than 28dB is available only for the 3-port polarization-maintaining optical circulator.

Unless otherwise specified, the slow axis of the fiber is aligned with the key of the PM fiber connector.

Slow axis working and fast axis blocked as standard, while operating on both the slow and fast axis available on request.

Operating on both the slow and fast axis is available only for the 3-port PM optical circulators.

For the device with connector, IL is 0.3dB higher, RL is 5dB lower, and ER is 2dB lower.

This polarization-maintaining optical circulator (1064nm 1310nm 1550nm) is customizable, and above specifications are subject to change without notice.
