Triple-Stone’s optical circulator is a compact, high performance component, with high isolation, low insertion loss, low PDL, high stability and reliability. It routes incoming signals from Port 1 to Port 2, and incoming Port 2 signals to Port 3,Port 3 to Port 4.So fiber optic circulators act as signal routers, transmitting light from an input fiber to an output fiber, but directing light that returns along that output fiber to a third port. They perform a similar function as an isolator, protecting the input fiber from return power, but also allowing the rejected light to be employed.
