Product Description

1x2(2x2) Polarization Insensitive PM Fused Coupler-1940~2100nm

Product Description

A "1x2 Fused WDM" refers to a type of fiber optic component, specifically a Wavelength Division Multiplexer (WDM) that uses fused fiber technology to combine or separate optical signals at two different wavelengths, with one input port and two output ports ("1x2") - essentially allowing you to send or receive two distinct data streams on a single fiber simultaneously; "fused" indicates the manufacturing technique where fibers are joined together by heating them to create the coupling mechanism.

Features

• Low Excess Loss
• High Stability & Reliability
• High Extinction Rati & Low Excess Loss

Applications

• Fiber Laser
• Fiber Amplifier
