100G SR4 optics can be used by a QSFP28 port that can be "split" into four channels of 25G (available on select switch models/modules on identified ports).

The following optical breakout cables can be used with 100G SR4 to split into 4x 25G SR compatible streams. These cables are ordered from the HPE Compute and Server or Storage business units and may not be available to Aruba-only resellers.

Fiber breakout cables (from HPE Server products):

  • (Server SKU) R1N86A, HPE 12 Fiber MPO to 4xLC MM 3m Cbl
