Product Description –

Nest Coupler 45/55 is a 1×2 optical coupler. One input port simplifies the use and cable management. Nest couplers are ideal for applications where light is split from the input port into two output ports at the specified coupling ratio. Nest Coupler 45/55 has a wide operating wavelength, wide operating temperature, low insertion loss and low-cost light distribution solution. The higher side will have more distribution and have more signal loss and the lower side (10) will have less distribution and less signal loss. Among other applications, Nest Coupler 10/90 is used for FTTX Systems, CATV Network, Fiber Sensors and Fiber optic Instruments  .
