CS optical connector.

The CS connector is a duplex FO connector in an extremely compact design. It belongs to the VSFF connectors

with a

Very Small Form Factor

(VSFF), to which the

MDC connector

and the SN connector also belong.TheVSFF connectors have the advantage that they can be used to significantly increase the connection density in data centers. Compared to LC

connectors, which belongs to the SFF connectors, Small Form Factor (SFF), the port density can be doubled.

Compared in size, the LC connector occupies an area of 11 mm x 13 mm and the CS connector an area of 5.3 mm x 7.8 mm. The two optical fibres are guided in a ceramic ferrule

with a diameter of 1.25 mm and a spacing of 3.8 mm. TheCS connector can be stacked extremely densely, which helps to increase the connection density.

The CS connector was developed for 200 Gigabit Ethernet (200GbE) and 400 Gigabit Ethernet (400GbE). Compared to the classic LC connectors, it is characterized by good insertion loss and return loss.
