Product Description

Optical Fiber Coupler 2050nm Polarization Maintaining Taper Coupler Dual Core 1x2 2x2
 

Product Description

A 532-2050nm Polarization Maintaining Fused Coupler (1X2/2X2) is a fiber optic device that can split or combine optical signals.
These couplers are used in applications that require high reliability and performance, such as fiber optic sensing, power monitoring, and coherent communication systems. 

Fused couplers are made by fusing and tapering fibers together. This method creates a compact, rugged, and simple way to split or combine optical signals. 

These couplers have low insertion loss, high extinction ratio, and a robust design. They are also bidirectional and offer low backreflection. 

Features

• Low Insertion Loss
• High Stability & Reliability
• Wavelength 532 - 2100nm available

Applications

• Fiber Sensors
• Power Monitoring
• Coherent Communication Systems
