25 Gbps SFP28 transceiver for Ethernet

The Mellanox MMA2P00-AS is a new SFP28 optical transceiver built for 25 Gbps Ethernet links. It uses an LC duplex interface to connect multi-mode fibre and presents an RJ-45 style electrical connector to the host. The module complies with IEEE 802.3bm and SFF-8402 standards. Operates at a nominal 850 nm wavelength over multi-mode fibre.

Suits 25 GbE links needing LC multi-mode

This transceiver fits switches or servers with SFP28 cages that require 25 Gbps operation over multi-mode fibre using LC patch cords. It is not for installations that need single-mode fibre, longer reach, or a different form factor such as QSFP28. Buyers needing copper RJ-45 twinax or direct-attach cables should look elsewhere.

IEEE 802.3bm 25 Gbps rate over MMF

The decisive specification is the IEEE 802.3bm 25 Gbps transfer rate over multi-mode fibre with LC connectors. Each optical channel runs at up to 25.78125 GBd and the module offers selectable retiming for the 25 Gbps rate. Confirm the host port supports SFP28 and 25GbE before purchase.

Questions about this item

Does the SFP28 module fit a standard SFP28 cage and use LC duplex connectors?

Yes, it plugs into any standard SFP28 cage and connects via dual LC connectors for multi-mode fiber.

How do I install the transceiver without damaging the LC ferrules?

Remove the dust caps, insert the module until it clicks, then connect the LC patch cables straight in — never force them at an angle.

When should I replace the 850 nm optics?

Replace the module if link errors rise or optical power drops below the receiver sensitivity for 25.78125 GBd operation.
