In order to make full use of the huge bandwidth resources of the optical fiber and increase the transmission capacity of optical fiber, a new generation of optical fiber communication technology based on dense WDM (DWDM) technology has been produced.
As the connection bandwidth of the terminal device increases, the 10 Gigabit Ethernet deployment can continue to expand beyond the core of the network, thereby improving the scalability of the network.
The optical cable is a communication line that a certain number of optical fibers form the cable core in a certain manner, the outer is sheathed, and some outer cladding layers, to realize optical signal transmission.
10G PON is already modern, so what is the next generation of PON? Why not 25G PON but 50G PON? Dr. Wang Li said that in the past, the standard speed of PON was increased by 4-10 times.
