Metropolitan area network is a computer communication network established within a city, referred to as MAN. It is a broadband local area network. Due to the local area network technology with active switching elements, the transmission delay in the network is small, and its transmission medium mainly uses optical cables, and the transmission rate is above 100Gbit/s. An important use of MAN is for...

At present, 5G has started the commercialization process, but the complex bearer scheme leads to the increase of the corresponding optical module types. For 5G forward transmission, in terms of speed, AAU has introduced the eCPRI protocol standard, and the forward 25G rate has become the standard of various equipment manufacturers. Because of this, the rate standard of the carrier network will be ...
