525nm, 630nm, 780nm, 850nm, 980nm 1x2,2x2 Polarization Maintaining
Fused Fiber Optic Coupler
Product Overview
1x2,2x2 Polarization Maintaining Fused Fiber Optic Coupler uses
unique fusing technique and polarization maintaining fiber to build
the polarization maintaining fused standard coupler (PMC).The
coupling ratio could be selected according to customer’s request.
It features low excess loss, small size and high polarization
extinction ratio. PMC is widely used for optical sensors and
optical gyro, optical amplifier.
Application
Fiber Amplifier
Power Monitoring
Fiber Optical Instrument
FEATURES
Low Insertion Loss
High Return Loss
High Extinction Ratio

Note: 1. the PM fused coupler is both axis working, no axis can be
blocked; default test extinction ratio is on the slow axis.
Above specifications are for device without connector, If with
connector, IL will be 0.3dB higher, return loss with be reduce 5dB
and Extinction Ratio will reduce 2dB.
2. For >10W high power applications, we will use heat sink
package
3. If there is pulse application, please be sure to inform us of
pulse energy and peak power.
