With the growth of IOT, cloud services, 4K video and 5G services, 

the processing capacity of global data centers is expected to grow by 

more than 35% CAGR per year. At the same time, the need to reduce 

latency requires data centers to be as close to users as possible, 

especially in delay sensitive applications such as unmanned driving. 

Starting from reducing size and reducing power consumption, data 

centers in the future need to be more compact and more 

energy-saving, SN connector is the next generation of higher density 

connector recently launched by Senko. SN and CS are both compact 

dual core connectors. Compared with high-density LC connector, the 

density of SN is increased by 40%. In order to facilitate the installation 

of pull tab with different length. CS supports four fiber application of 

QSFP, the installation density of LC is doubled. The pitch of SN is only 

3.1 mm, which is more compact and supports 8-fiber application.
