What are CIS-QSFP-4X10G-AOC10M Cables?

CIS-QSFP-4X1?oG-AOC10M cables, also known as Copper InfiniBand Direct Attach Cables or Active Optical Cables (AOCs), are a type of high-performance cable designed for short-distance data transmission within a data centre. They combine the electrical connector standards of SFP+ (Small Form-factor Pluggable) with the data transmission capabilities of InfiniBand cables.

Here’s a breakdown of the key components in the cable name:

CIS: Copper InfiniBand – Indicates the cable uses copper conductors for data transmission.

QSFP: Quad Small Form-factor Pluggable – Refers to the connector type on each end of the cable. QSFP connectors are designed for higher data rates compared to SFP+ connectors.

4X10G: Represents four 10 Gigabit Ethernet lanes. This means the cable can support four independent 10GbE connections simultaneously.

AOC: Active Optical Cable – Indicates that the cable uses electronic components to amplify the signal for longer reach compared to passive copper cables.

10M: Represents the cable length, which in this case is 10 meters.
