The FWDM is a kind of WDM technology based on TFF, which uses thin film filters with excellent performance to ensure high-quality optical performance, stability and reliability. It can realize the multiplexing and demultiplexing of 1310nm, 1490nm and 1550nm signals, so that the transmission capacity of a single optical fiber can be multiplicated. It is widely used in optical fiber upgrading, capacity expansion or the introduction of integrated new services, such as radio and television, telecommunications, Internet and so on.
