10GBASE-SR SFP+ 850nm 300m DOM LC MMF Transceiver Arista SFP-10G-SR Compatible

10GBASE-SR SFP+ Transceiver for Arista SFP-10G-SR Ports

This 10GBASE-SR SFP+ transceiver is a hot-swappable 10G optical module built for multi-mode fiber links inside data centers, server rooms and campus backbones. It transmits at 850nm through an LC duplex MMF interface and reaches 300m over OM3 fiber and 400m over OM4 fiber, so one part number covers most short-reach 10G cabling plans. The module is coded with an Arista-compatible EEPROM, which means an Arista switch identifies it as SFP-10G-SR (cross reference XVR-00001-02) and brings the port up without any manual configuration. Digital optical monitoring is enabled on every unit, giving your NOC live readouts of Tx power, Rx power, temperature, voltage and laser bias. Every 10GBASE-SR SFP+ transceiver leaves our warehouse after a full test cycle covering eye diagram,center wavelength, receiver sensitivity and EEPROM read-back, and each unit carries a unique serial number for traceability.

Technical Specifications

Where It Fits and Why Buyers Choose It

• Data center top-of-rack uplinks: the 10GBASE-SR SFP+ transceiver links Arista leaf and spine switches over OM3 or OM4 patch cords at 300m and 400m, which keeps 10G port costs low in dense racks.
• Server to switch connections: pair it with 10G NICs and DAC-free cabling to move virtual machines, backup traffic and storage replication without touching single-mode optics.
• Campus and enterprise backbone: short 10G runs between floors or buildings run on existing MMF infrastructure, so no recabling budget is needed.
• Monitoring built in: DOM on the 10GBASE-SR SFP+ transceiver reports live optical levels, so technicians spot a dirty connector before the link drops.
• Low power, low heat: the module draws under 1W, which matters when 48 ports sit side by side in a switch.
• Coding that matches the switch: Arista EEPROM coding on this 10GBASE-SR SFP+ transceiver avoids the common support ticket of a port that stays down on a third-party optic.
• Tested, not just assembled: wavelength, eye margin, sensitivity and DDM calibration are verified unit by unit before packing.

Frequently Asked Questions

Is this 10GBASE-SR SFP+ transceiver coded for Arista switches?

Yes. The EEPROM is programmed with Arista SFP-10G-SR data, and the module also cross references XVR-00001-02. Arista switches read the module as a native short-reach 10G optic and bring the port up without extra commands. If you run a mixed fleet, we can supply the same hardware coded for Cisco, Huawei, Juniper or generic MSA use on request.

What distance can I expect on my existing fiber?

On OM3 multi-mode fiber the 10GBASE-SR SFP+ transceiver reaches 300m, and on OM4 it reaches 400m. For legacy OM2 fiber, plan short runs and check the link budget first, because modal bandwidth, not the module, becomes the limit.

Does it support digital diagnostics?

Yes. DOM follows SFF-8472, so temperature, supply voltage, Tx bias, Tx power and Rx power are readable from the switch CLI or your monitoring platform. That data is what makes predictive maintenance practical on a 10GBASE-SR SFP+ transceiver.

How is the module packed and shipped?

Each 10GBASE-SR SFP+ transceiver sits in an individual anti-static bag with an ESD foam insert, then in a carton with dust caps fitted. Stock orders leave in 3 to 5 working days; bulk production runs take 15 to 20 days. A 3-year warranty covers the module, and dead-on-arrival units are replaced directly.

Can you support OEM branding and volume pricing?

We are a distributor and wholesaler established in 2007, exporting about 40 to 50 percent of our volume. Label printing, private packaging and firmware coding for the 10GBASE-SR SFP+ transceiver are available from 100 pieces, and the price breaks are quoted per project.
