What cabling type is this HPE Synergy QSFP+ transceiver designed for?

This transceiver is categorized as a 40GbE or 4x10GbE or 4x8Gb FC SR4 MPO multimode fiber module. It is intended for use with multimode fiber cabling that terminates in MPO connectors, aligning with SR4 style short reach optical connections commonly deployed inside Synergy racks or rows.

Which connector and form factor does the HPE 817040-B21 use?

The product is an HPE Synergy QSFP+ Transceiver and is listed under a 40GbE or 4x10GbE or 4x8Gb FC SR4 MPO multimode fiber category. This indicates it uses a QSFP+ transceiver form factor with an MPO optical interface, suitable for Synergy switches and interconnects that expose QSFP+ ports expecting MPO multimode connectivity.

Can the HPE 817040-B21 be used for Fibre Channel connectivity?

Yes, based on the model designation, the HPE Synergy 40GbE or 4x10GbE or 4x8Gb FC QSFP+ Transceiver supports 4x8Gb FC operation. This allows the same QSFP+ optical module to participate in Fibre Channel configurations where 8Gb FC links are required alongside Ethernet capabilities.

Is the HPE 817040-B21 suitable for short reach optical links in Synergy environments?

The transceiver is identified as an SR4 MPO multimode fiber module within its category, which is typically used for short reach optical connections. This makes it appropriate for intra-rack or intra-row Synergy deployments that use MPO multimode fiber to provide 40GbE or split-link connectivity between Synergy modules.

Product overview

The HPE Synergy 40GbE or 4x10GbE or 4x8Gb FC QSFP+ Transceiver 817040-B21 is designed for Synergy infrastructures that require QSFP+ optical connectivity. This transceiver integrates a QSFP+ form factor and uses multimode fiber cabling to deliver 40GbE connectivity through an MPO interface. It supports deployment as a 40GbE uplink using an MPO to MPO cable or as breakout connections using MPO to 4x LC cabling for 4x10GbE or 4x8Gb FC configurations. With a compact physical profile and defined environmental operating ranges, it fits Synergy architectures that standardize on QSFP+ modules. This transceiver is suitable where MPO multimode cabling and 40GbE or split-link configurations are part of the network design. Procurement teams can align this module to Synergy switch and compute modules that specify QSFP+ MPO multimode connectivity at 40GbE line rate or equivalent split-channel operation.
