Product Description

Grade P 1x2 2x2 980nm WDM 2000nm Wavelength Division Multiplexer Coupler 

Product Description

1x2 couplers are manufactured using the same process as our 2x2 fiber optic couplers, but have only one input port for simplified use and cable management. These couplers are ideal for applications where light is split from the input port into two output ports at the specified coupling ratio; unlike WDMs, they are generally not recommended for beam combining applications. The unused port is internally terminated within the coupler housing in a manner that minimizes back reflections 

Features

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

Applications

• Fiber Optical Laser
• Fiber Optical EDFA
