SFP-10G-SR: frequently asked questions
What is the Arista SFP-10G-SR?
The Arista SFP-10G-SR is a SFP+ 10GBASE-SR module from Arista Networks for 10 Gbps links. It plugs into a SFP+ (or SFP25) port on an Arista switch and is used for server access, top-of-rack and campus uplinks, storage networks and metro links.
What is the maximum distance of the SFP-10G-SR?
Arista specifies the SFP-10G-SR for 300 m on OM3 and 400 m on OM4 multimode fiber (33 m / 66 m / 82 m on older OM1/OM2-grade fibre).
What are the transmit and receive power levels of the SFP-10G-SR?
Per Arista's published optics data sheet, the SFP-10G-SR transmits −7.3 to −1.0 dBm and receives −9.9 to −1.0 dBm.
Which fiber and connector does the SFP-10G-SR need?
The SFP-10G-SR uses a Duplex LC connector on multimode (OM3/OM4), at 850 nm. Both ends of the link must use the same optical standard.
Is the SFP-10G-SR compatible with my Arista switch?
It works in Arista switches with SFP+ (or SFP25) ports that support this optic. Send us your switch model and EOS version and we will check it against Arista's Transceiver and Cable Guide before dispatch, so you only receive a module that works in your port.
SFP-10G-SR vs SFP-10G-SRL: what is the difference?
Both are 10GBASE-SR optics at 850 nm and interoperate with each other. SFP-10G-SR reaches 300 m on OM3 / 400 m on OM4; SFP-10G-SRL is the short-reach version for 100 m on OM3 / 150 m on OM4, ideal inside a rack or row.
Is your SFP-10G-SR genuine Arista?
Yes. Next Gen Networks supplies original Arista Networks optics, not third-party lookalikes or grey-market stock. Every unit is checked before dispatch, and we share the serial numbers on request so you can verify them in EOS ('show inventory').
What is the SFP-10G-SR price in India and how do I order?
The Arista SFP-10G-SR price in India depends on quantity, delivery city and current stock. Next Gen Networks supplies it with a GST invoice (input tax credit ready) and pan-India dispatch from New Delhi. Send the part number, quantity and delivery city on WhatsApp +91-7827955775 or email Sales@nextgennetworks.in and we reply with a GST quote.
How much power does the SFP-10G-SR draw?
Arista lists maximum power of 1 W for the SFP-10G-SR. Check your switch's per-port power budget for dense deployments.
