The filter-type wavelength division multiplexer (FWDM) is based on mature thin film filter technology, with wide channel bandwidth, low insertion loss, and high channel isolation.
It is widely used in single-mode optical fiber communication systems and DFA.
FWDM wavelength division multiplexer: 3-port multi-mode filter type wavelength division multiplexer (1310/1550nm) can realize the multiplexing and demultiplexing of the optical signals of the two communication windows of 1310nm and 1550nm.
Excellent thin film filters are selected to ensure high High-quality optical performance, stable and reliable, can realize fiber bidirectional channel
