Even if the data center is developing at a high speed, such as 100G or 200G, 10G / 40G optical modules are still popular, because there are many scenarios that only need 10G or 40G. In today's tough competition, people have higher and higher requirements on quality, so to adapt to the development of this phenomenon, we must improve the quality of products. For this reason, ETU-Link does this. Opti...

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...
