882251-B21 is the HPE Synergy 100GbE/4x25GbE/4x32GbFC QSFP28 transceiver. It has one MPO 100-GbE port (IEEE 802.3 type 100GBASE-SR4) with an 850 nm wavelength and a QSFP28 form factor. HPE describes its spare, P00430-001, as a StoreFabric QSFP28 transceiver.
HPE gives link distances of 100 m on OM4 fibre at 1.0 dB loss and 85 m on OM4 at 1.5 dB loss, over OM3 or OM4 multimode cable. HPE advises ultra physical contact (UPC) polish on fibre patch cords and does not recommend angled physical contact (APC). Maximum power is 3.5 W from a 3.3 V supply. Operating temperature is 0 to 70 degrees C and operating humidity is 5% to 95% non-condensing. The module is 18.35 x 122.3 x 12.90 mm and weighs 44 g.
On the HPE Virtual Connect SE 100Gb F32 Module for Synergy it is one of the QSFP28 uplink transceivers. HPE supports 4x8Gb, 4x16Gb and 4x32Gb Fibre Channel modes with it, and does not support mixing Ethernet and Fibre Channel port types on it. HPE lists the 25Gb SFP28 SR 100m transceiver 845398-B21 in the same transceiver range. See more HPE adapters and transceivers, or the 25Gb SFP28 SR transceiver 845398-B21.
