Frequently Asked Questions
A polarization-maintaining fiber optical circulator is a passive component that transmits light signals from one port to the next sequential port with low loss, while blocking any light transmission to the previous port. It maintains the same state of polarization (SOP) of the light signals using polarization maintaining fiber (PMF).
The features of the polarization-maintaining fiber optical circulator include low insertion loss, high isolation and extinction ratio, and high reliability and stability.
Yes, the polarization-maintaining fiber optical circulator can work on both slow-axis and fast-axis linear polarizations, or it can transmit one principal polarization state in only one direction and block the orthogonal state in both directions.
Yes, the specifications include the type (3-port or 4-port), center wavelength (1310nm or 1550nm), operating wavelength range, insertion loss, isolation, extinction ratio, cross talk, return loss, optical power, tensile load, operating temperature, and storage temperature.
Yes, the polarization-maintaining fiber optical circulator is customizable. Customers can contact Lfiber's sales department for availability and product customization options.
