HP compatible C8R25B Description
EdgeOptic's C8R25B compatible is an HPE-coded version of the EdgeOptic 10G-SFP-300 multi-vendor 10GBASE-SR SFP+ transceiver. C8R25B is HPE's part number for the MSA 10Gb Short Range iSCSI SFP+ used in HPE MSA storage controllers. Despite the C8R prefix that some HPE part numbers share with Brocade-derived FC SAN modules, C8R25B is an iSCSI-over-Ethernet transceiver, not an FC SAN optic. The EEPROM is coded for HPE MSA host bus recognition.
The OEM C8R25B is sold as a 4-pack PID intended for stocking redundant transceivers across an MSA controller pair. Engineers replacing a single failed module typically don't need four units, which is the procurement gap the EdgeOptic single-unit compatible fills. HPE's own single-unit variant uses the C8R25B-1PK suffix; the EdgeOptic compatible covers both ordering paths with HPE-recognized vendor identification.
Optical specs follow the 10G-SFP-300 root: 850 nm transmit and receive, 20 nm bandwidth (840 to 860 nm), 300 m over OM3 and 400 m over OM4 / OM5 multimode fiber, duplex LC/UPC connector, 6.1 dB average link budget. Transmit power is −5 to 0 dBm, receiver sensitivity is −11.1 dBm, and receiver overload is 0 dBm. The transmitter is a VCSEL laser, the receiver a PIN photodiode, and DOM/DDM is supported per SFF-8472 for monitoring TX bias, optical power, voltage and case temperature.
Standard target chassis are HPE MSA 2040, MSA 2050, and MSA 2060 storage arrays running iSCSI host ports over 10GBASE-SR optics. The 10GBASE-SR / iSCSI distinction matters: MSA controllers use Ethernet-framed iSCSI on these ports, not Fibre Channel. For comprehensive cross-generation MSA compatibility, including any newer MSA SKUs, verify against HPE's MSA transceiver compatibility list before deployment. Operating temperature is 0 to 70 °C commercial.

Frequently Asked Questions
HPE sells C8R25B only as a 4-pack. Can I buy a single replacement transceiver from EdgeOptic?
Yes. The HPE C8R25B PID ships from HPE as a 4-pack, intended for stocking redundant SFP+ optics across an MSA controller pair. The EdgeOptic compatible is sold as single units, so MSA administrators replacing one failed transceiver order one piece, not four. Vendor identification is coded for HPE MSA host bus recognition, the same as the OEM module.
Is C8R25B a Brocade Fibre Channel transceiver, or HPE iSCSI Ethernet?
HPE iSCSI Ethernet. The C8R prefix is shared by both HPE MSA storage iSCSI optics and some legacy Brocade-derived HPE FC SAN parts, which is the source of the confusion. C8R25B specifically is an HPE MSA 10Gb Short Range iSCSI SFP+ optic for 10GBASE-SR Ethernet links between MSA controllers and 10GbE iSCSI initiators. Brocade FC SAN modules use different HPE part numbers (the AJ716B / AJ718A series for 8GFC, for example), and they are not interchangeable with C8R25B.
