Facing 400G, the challenge we are facing is how to provide, add 

and support applications with high density and large bandwidth in 

the super large data center. These applications need a lot of space 

to accommodate a large number of cables. Low insertion loss, high 

fiber density, easy installation and stable performance are all 

necessary considerations for the next generation of 400G data 

center. 400G network transmission for MTP/MPO connector as the 

connection interface, we can use 32, 16 or 8 cores optical fiber 

transmission, while CS connector brings higher density fiber 

connection application scheme for 400G. The maximum capacity of 

1U is 320 ports, and the panel density is 2.65 times higher than LC 

dual core connector.
