FWDM Cassette

FWDM Cassette

The FWDM CASSETTE of PHX adopts thin-film filter with excellent performance to ensure high-quality optical performance, stability and reliability. The filtered wavelength division multiplexer can realize optical signal transmission and segmentation in 1310nm, 1490nm and 1550nm communication windows, and can also realize optical fiber bidirectional communication. It is widely used in optical fiber upgrading, capacity expansion or the introduction of new integrated services, such as radio and television, telecommunications, Internet and so on.
