What Ethernet speeds does the HPE 882251-B21 transceiver support?

The HPE Synergy 100GbE, 4x25GbE, 4x32GbFC QSFP28 Transceiver 882251-B21 supports 100GbE Ethernet connectivity and can also be used for 4x25GbE operation. This allows it to serve both as a 100GbE uplink and as a breakout option for 25GbE links in Synergy environments using the same QSFP28 MPO multimode module.

Can this transceiver be used for Fibre Channel storage connectivity?

Yes. The 882251-B21 transceiver supports 4x32Gb Fibre Channel operation, in addition to Ethernet capabilities. This makes it suitable for environments that require high-speed Fibre Channel connectivity for storage fabrics while using the same QSFP28 MPO multimode form factor deployed for Ethernet links.

What type of connector and fiber does the 882251-B21 use?

The HPE Synergy 100GbE, 4x25GbE, 4x32GbFC QSFP28 Transceiver 882251-B21 uses an MPO multimode optical interface. This means it is designed for use with multimode fiber cabling terminated in MPO connectors, which is common in high-density data center and Synergy cabling infrastructures.

Which form factor does the HPE 882251-B21 transceiver use?

The transceiver is specified as a QSFP28 module. This form factor is widely used for 100GbE and related breakout configurations, making the 882251-B21 suitable for deployment in Synergy modules and switches that expose QSFP28 ports for high-bandwidth connectivity over MPO multimode cabling.

Is the 882251-B21 specific to HPE Synergy deployments?

The product name identifies it as the HPE Synergy 100GbE, 4x25GbE, 4x32GbFC QSFP28 Transceiver. This indicates it is intended for Synergy environments where 100GbE, 4x25GbE and 4x32Gb Fibre Channel connectivity is required over MPO multimode fiber using a QSFP28 form factor.
