HP compatible 455886-B21 Description
455886-B21 is HPE’s option part number for a BladeSystem c-Class 10Gb SFP+ LR transceiver, designed for Virtual Connect FlexFabric modules in c7000 blade enclosures. EdgeOptic’s compatible replacement is built on our 10G-SFP-10 platform, coded with the HPE vendor data that Virtual Connect firmware validates during module initialization. The compatible provides identical optical performance to the original HPE optic.
The transceiver uses a 1310 nm DFB laser and PIN photodiode receiver, providing 10 Gbps over up to 10 km of G.652 single-mode fiber through duplex LC/UPC connectors. It conforms to IEEE 802.3ae, SFF-8431, SFF-8432, and SFF-8472 (DDM). Maximum channel insertion loss remains within the standard 6.3 dB link budget. Commercial operating temperature range is 0°C to 70°C, and power consumption stays under 1 W per the SFP+ MSA.
HPE maintains two part numbers for this module: 455886-B21 is the option number used when ordering through HPE’s sales catalog, and 455888-001 is the spare part number referenced in hardware maintenance manuals, QuickSpecs documents, and Virtual Connect configuration guides. Both refer to the same physical transceiver with the same specifications. When searching HPE’s parts catalog, BladeSystem compatibility matrices, or third-party inventory systems, either number will return the correct SFP+ LR module. EdgeOptic’s compatible is listed under the 455886-B21 ordering code.
The 455886-B21 installs in Virtual Connect FlexFabric 10Gb/24-port and FlexFabric-20/40 F8 modules within the c7000 enclosure. These Virtual Connect modules provide 10GbE uplinks from the blade enclosure to the data center core or aggregation switching layer. The LR variant is used when the uplink fiber run exceeds the 300 m limit of short-reach multimode optics, typically connecting blade chassis in one row to top-of-rack or end-of-row switches in another part of the data center. In larger facilities, the 10 km reach covers connections between blade enclosures and core switches in different buildings or data halls.
HPE BladeSystem environments often run dozens or hundreds of SFP+ modules across multiple c7000 enclosures. EdgeOptic provides full DDM telemetry (Tx/Rx optical power, temperature, supply voltage, laser bias current) and a lifetime warranty on all HPE-compatible optics. DDM values are visible through Virtual Connect Manager and the Onboard Administrator. For BladeSystem deployment quantities or Virtual Connect compatibility verification, contact our sales team
Frequently Asked Questions
What is the relationship between 455886-B21 and 455888-001?
455886-B21 is HPE’s option part number for ordering. 455888-001 is the spare part number that appears in hardware maintenance manuals and QuickSpecs. Both refer to the same BladeSystem c-Class 10Gb SFP+ LR transceiver.
Which Virtual Connect modules accept the 455886-B21?
The 455886-B21 is listed for Virtual Connect FlexFabric 10Gb/24-port and FlexFabric-20/40 F8 modules in the c7000 enclosure. It installs in the SFP+ uplink ports that connect the blade chassis to the external switching infrastructure.
Can the 455886-B21 be used in HPE ProLiant rack servers?
The 455886-B21 is coded specifically for HPE BladeSystem Virtual Connect modules. For ProLiant rack servers with SFP+ NICs, HPE uses different part numbers (such as the 455883-B21 for SR or server-specific FRU numbers for LR). Check the ProLiant server’s QuickSpecs for the correct SFP+ LR part number.
