Product Description

Wide Operating Wavelength Range High Power PM Fiber Optical Circulator

Product Description

An optical circulator is a device that separates and directs light traveling in opposite directions through an optical fiber. It's a multiport device with three or more ports, where light enters one port and exits the next. For example, if light enters port 1, it exits port 2, but if some of the light reflects back, it exits port 3 instead of port 1

Features

• Low Insertion Loss
• High Return Loss
• High Extinction Ratio
• High Stability & Reliability

Applications

• Erbium-Doped Fiber Amplifiers (EDFA) & Raman Fiber Amplifiers
• Fiber Sensing
• Fiber Instruments
