Product Description

Polarization Maintaining Fused Coupler

Description:

OF uses FBT technique with polarization maintaining (PM) fiber to build the PM coupler (PMC). The coupling ratio can be easily adjusted according to customer’s request. It features low excess loss, small size and high polarization extinction ratio (PER). PMC is widely used for optical sensors and optical gyro..

Features:

l Low insertion loss and excess loss

l Excellent stability and reliability

l Working wavelength and coupling ratio flexible adjusted

Applications:

l Fiber gyro

l Fiber Sensors

l PM amplifier
