About this product
HPE 25Gb SFP28 SR 100m Transceiver (845398-B21)
The HPE 25Gb SFP28 SR 100m Transceiver (845398-B21) provides 25 Gigabit Ethernet optical connectivity for supported HPE infrastructure using multimode fibre. It is a single-lane short-reach optical module with an SFP28 form factor and an LC optical interface.
The module uses an 850 nm optical wavelength and the IEEE 25GBASE-SR physical-layer specification. HPE rates this module for up to 70 m on OM3 multimode fibre or up to 100 m on OM4 fibre when the relevant optical-link requirements are met. HPE specifies that the device operates at 25GbE and does not function as a 10GbE module.
This model is intended for use in compatible HPE adapter, switch and server environments that support the designated 25 Gb SFP28 SR optic. Fibre patching uses an LC connection and an appropriate multimode-fibre cable.
Key Features
- 25 Gb Ethernet SFP28 short-reach optical module.
- 850 nm optical wavelength for multimode-fibre connections.
- LC connection and support for OM3/OM4 fibre.
- Up to 70 m on OM3 or 100 m on OM4 according to HPE QuickSpecs.
- 25 GbE only; HPE states this module does not operate at 10 GbE.
