What are CS Connectors?

CS connectors are a new optical connector format which are physically similar to the tried and true LC format, while providing up to 40% higher density. It uses the same 1.25 mm ferrule but has a much tighter spacing, allowing for many more connections in the same physical space.

Advantages of CS Connectors

CS connectors are much smaller than LC connectors. They are small enough in fact to allow two CS connectors on  a single QSFP-DD module. This allows for doubling the port density in a typical switch.

 The smaller size also allows for much higher density on the patch panel side. A typical 1RU patch panel that can accommodate 256 LC fiber connections can fit 336 fiber connections when using CS connectors. 

That’s a 31% increase in capacity. The density advantages can become even more dramatic when comparing full racks which can be even more efficient in their spacing.


Who benefits the most from CS Connectors?

High density environments will benefit the most from CS connectors.

A single 400G 32 port QSFP-28 switch can accommodate 64 200G connections directly without using an MPO (MPO—Multi-fiber Push On) breakout connector.

When using eight to one MPO breakouts, a single 1RU 32 port QSFP-28 switch can accommodate a whopping 256 50G connections.

When density is a requirement, there is no beating the CS connector.

What about price?

At the moment the CS connector is more expensive than the ubiquitous LC connectors. That may change over time as more users adopt CS. We’ll have to wait to see how popular the new standard will be.
