LWDM is a wavelength division multiplexing LAN WDM technology based on Ethernet channel, also known as fine wavelength division multiplexing. The channel spacing is 200 ~ 800ghz, which is between DWDM (100GHz, 50GHz) and CWDM (about 3thz)
LAN WDM (LWDM) is based on TFF technology and adopts free space sealing structure, it is of compact size, low insertion loss, and high isolation. It is widely applied in the CFP module.
