Product Description

633nm 1550nm Optic Fiber Fused Pm Coupler for Pump Laser

Product Description

A fused PM coupler, or polarization maintaining fused fiber coupler, is a device that splits or combines optical signals between multiple fibers.

Fused PM couplers are made by fusing and tapering two or more optical fibers together, creating a coupling region where the cores of the fibers are close together.

 

Features

• Low Insertion Loss
• High Return Loss
• High Stability & Reliability
• High lsolation

Applications

• EDFA
• Pump Laser
• Optical Cutting
• Research
