3 Ports FWDM (Multi-Mode)

Through three-port design and thin-film filter technology, it achieves multiplexing and demultiplexing of dual-wavelength signals with low insertion loss, high isolation and compact design, etc. It is widely used in the fields of fibre-to-the-home, cable TV, fibre-optic sensing, monitoring system, industrial communication and telecommunication network, etc., which improves the transmission efficiency and reliability of fibre-optic network.
