Models, specifications, and compatibility

QSFP28 optical transceiver modules provide a transmission rate of 100 Gbps and use MPO connectors.

Table 5: Specifications for QSFP28 optical transceiver modules that use MPO connectors (1)
Product name (SKU) DOM - Digital Optical Monitoring (4x4 part #) Central wl (nm) Fiber mode Fiber diameter (µm) Modal bandwidth (MHz*km) Transmission distance
Aruba 100G QSFP28 MPO SR4 100m 12-fiber MPO MMF Transceiver (JL309A) YES

(1990-4680, 1990-4678)

850 MMF 50/125 2000 (OM3)

4700 (OM4)

70 m (229.66 ft)

100 m (328.08 ft)

NOTE:

SR4 is not supported for use over MMF OM1 or OM2 fiber. (The IEEE standard does not state a specification.) Use MPO Female connectors (no pins) with MPO transceivers.

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).

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

  • (Storage SKU) K2Q46A, HPE MPO to 4 x LC 5m Cable

  • (Storage SKU) K2Q47A, HPE MPO to 4 x LC 15m Cable

See Splitting of QSFP+ and QSFP28 ports.
