PM 1310/1550 nm Fiber Optic Isolator
This PM 1310/1550 nm Fiber Optic Isolator is designed for applications requiring precise polarization control and high isolation. It features low insertion loss, high return loss, and operates on the slow axis while cutting off the fast axis to maintain signal integrity.
Available in single and dual stage configurations for 1310nm and 1550nm wavelengths, the isolator is ideal for CATV systems, fiber amplifiers, and telecommunications. Compatible with PM1550 and PM1310 fibers, it supports various connector types and fiber lengths to meet specific system requirements.
