QSFP Breakout Capability and Module Interoperation

Some of Cisco’s QSFP modules have the capability to be operated in breakout mode on specific platforms. This allow the QSFP port to be configured as if it were two 100G or four 50GE ports. This function provides users the ability to use the latest 200G or 400G ports platforms with the latest features while still providing connectivity to existing 50GE or 100GE platforms that are already in the network. This eases the migration to higher speeds on a port-by-port basis while providing very-high density Ethernet interfaces. These modules will interoperate with Cisco as well as 3rd party modules that comply with the same standards. Tables 7-10 provides brief overview of the various optical breakout options, compatibility and reach to 100GE modules. Module optical interoperability can also be verified with the Cisco Module Interoperability Matrix.
