3 Ports FWDM Device

What is the origin of optical communication?

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.

FWDM Splitter, also known as Filter WDM Splitter and Filter WDM, along with dense WDM splitter and coarse WDM splitter, are the most commonly used WDM device in construction of PON.
