FWDM - Filter Wavelength Division Multiplexer Since the "optical telephone" device designed by Bell in 1880 was proved that light waves can transmit information, the era that truly brought optical communications came after the 1980s. A complete optical communication system should meet three conditions: light source, optical fiber, and photoelectric detection. In 1966, the United States borrowed from the Chinese Dr. Gao Kun to publish a thesis, pointing out that "quartz glass fiber is used to transmit optical signals for communication." In 1970, Corning Corporation of the United States successfully developed optical fiber, which provided an ideal transmission medium for optical communications. During this period, semiconductor lasers were also successfully developed, and light sources with wavelengths suitable for optical fiber low-loss transmission played a decisive role in optical fiber communications, all of which made the development of optical fiber communications extremely rapid.

Filter Wavelength Division Multiplexer (FWDM) is based on mature thin film filter technology. It has the characteristics of wide channel bandwidth, low insertion loss, high channel isolation, high environmental stability and reliability, and is widely used in single-mode optical fiber communications. System and DFA.
A key advantage of DWDM is that its protocol and transmission speed are irrelevant. The DWDM-based network can use IP, ATM, SONET/SDH, and Ethernet protocols to transmit data, and the processed data flow is between 100Mb/s and 2.5Gb/s. In this way, DWDM-based networks can transmit different types of data traffic at different speeds on a laser channel. From the point of view of QoS (Quality of Service), DWDM-based networks quickly respond to customer bandwidth requirements and protocol changes in a low-cost manner.
