SFP-10G-LR: frequently asked questions
What is the Arista SFP-10G-LR?
The Arista SFP-10G-LR is a SFP+ 10GBASE-LR 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-LR?
Arista specifies the SFP-10G-LR for 10 km on duplex G.652 single-mode fiber.
What are the transmit and receive power levels of the SFP-10G-LR?
Per Arista's published optics data sheet, the SFP-10G-LR transmits −8.2 to 0.5 dBm and receives −14.4 to 0.5 dBm.
Which fiber and connector does the SFP-10G-LR need?
The SFP-10G-LR uses a Duplex LC connector on single-mode (G.652), at 1310 nm. Both ends of the link must use the same optical standard.
Is the SFP-10G-LR 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-LR vs SFP-10G-LRL: what is the difference?
Both run 10GBASE-LR at 1310 nm on single-mode fiber and interoperate. SFP-10G-LR reaches 10 km; SFP-10G-LRL is the 1 km version for in-building and campus links.
Is your SFP-10G-LR 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-LR price in India and how do I order?
The Arista SFP-10G-LR 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-LR draw?
Arista lists maximum power of 1 W for the SFP-10G-LR. Check your switch's per-port power budget for dense deployments.
