Polarization Maintaining Filter Coupler
850nm 1x2 Broadband
Optic Fiber Filter Coupler (Filter Coupler) is a device made with thin-film filters technology, is designed for power splitting tapping telecommunication system. It’s available individually or integrated into modules. It’s been used in many fields, such as optical communication system, CATV networks, fiber optic sensor, optical channel monitoring, Optical Amplifier, FTTH/PON, LAN, and test equipment. VFibre’s filter coupler features low insertion loss, low polarization dependent loss, wide bandwidth, environmentally stable and reliability.
