Intel E25GSFP28SR — 10/25GbE SFP28 SR Optic

10/25 GbESFP28 SR850 nmIntel E810

The Intel E25GSFP28SR is Intel’s Ethernet SFP28 SR optic: an 850 nm short-reach multimode transceiver that runs at 25 or 10 Gbps over a duplex LC connection, with digital diagnostics. Intel lists it for its Ethernet 800 Series adapters such as the E810-XXVDA2 and E810-XXVDA4, so it is the optic to order when an Intel 25G server card needs a fibre link to the switch. In practice, multimode optics are the cheaper choice for links inside one building: most server rooms and floor risers already carry OM3 or OM4 fibre, and the module plus a short patch cord is all a port needs. Before you order, check the fibre grade printed on the cable jacket and the real length of the run, including patch panels.

Compatibility — check before buying:
It is a multimode optic and will not work over single-mode fibre. Intel lists it for the E810-XXVDA2, E810-XXVDA4, E810-CQDA1 and E810-CQDA2; other adapters are not in the list we checked. The switch end needs its own SR optic at the same speed. Keep the dust cap on until you connect the fibre, and clean both connector ends before every mating — dirt is the most common cause of a link that will not come up. Not sure? Send us your device model and the cable run and we check it before you order.

Best For

✓ Intel E810 25G server adapters
✓ Server-to-top-of-rack switch links
✓ 10G or 25G over OM3 / OM4
✓ Keeping optics and adapter from one vendor
✓ Replacing a failed Intel optic
✓ Data rooms with multimode cabling

Key Features

 
Dual-rate 10/25GbE
Runs at 25 or 10 Gbps, so the same optic serves a 10G switch today and 25G later.
 
Short-reach multimode
An 850 nm SR optic for the short runs between a server adapter and its top-of-rack switch over OM3 or OM4 multimode fibre.
 
Monitoring you can read
Digital diagnostics (SFF-8472) let the host report temperature, laser power and received light, so a dirty connector or a failing link shows up before users call.
 
Hot-swappable
Modules plug into a live port without shutting the switch down, so a link can be added or replaced during working hours. Seat it until it clicks and use the latch to remove it.

Frequently Asked Questions

Does it run at 10G?
Yes. Intel publishes it as a 10/25GbE optic. Both ends of the link must run the same speed.
Which adapters take it?
Intel names the E810-XXVDA2, E810-XXVDA4, E810-CQDA1 and E810-CQDA2. Send us your adapter model if it is not on that list.
Are fibre patch cords included?
No. You get 1 optic (Intel does not publish a contents list). The patch cord for the Duplex LC connector, a matching module for the far end of the link and a fibre cleaning tool are bought separately. Tell us the distance and the fibre type and we quote the right cord.
Will it work in a switch from another brand?
Intel lists this optic for its own Ethernet adapters. Operation in switches or other brands’ network cards is not something Intel publishes, so we do not promise it — send us the model and we check it.
Singular Expert Insight
We order the E25GSFP28SR for customers who want an Intel optic in an Intel E810 adapter, so support stays with one vendor. Match it with an SR optic at the switch and keep the run short on OM3 or OM4. Every order is backed by Singular’s local support in Cyprus — if a link will not come up, send us the port status and we help you find out whether it is the module, the cable or the configuration. Browse all transceivers and DAC cables or the switches they plug into.

Buyer’s Guide
