SFP-10G-ER: frequently asked questions
What is the Arista SFP-10G-ER?
The Arista SFP-10G-ER is a SFP+ 10GBASE-ER 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-ER?
Arista specifies the SFP-10G-ER for 40 km on duplex G.652 single-mode fiber (links beyond 30 km are engineered links per IEEE 802.3ae). Arista notes that proper optical attenuation is required on shorter links to protect the receiver from damage.
What are the transmit and receive power levels of the SFP-10G-ER?
Per Arista's published optics data sheet, the SFP-10G-ER transmits −4.7 to 4.0 dBm and receives −15.0 to −1.0 dBm.
Which fiber and connector does the SFP-10G-ER need?
The SFP-10G-ER uses a Duplex LC connector on single-mode (G.652), at 1550 nm. Both ends of the link must use the same optical standard.
Is the SFP-10G-ER 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-ER vs SFP-10G-ZR: which reach do I need?
Both run at 1550 nm on duplex single-mode fiber. SFP-10G-ER covers up to 40 km; SFP-10G-ZR covers up to 80 km. Choose by your fibre length and measured link loss; both need attenuation on short links.
Is your SFP-10G-ER 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-ER price in India and how do I order?
The Arista SFP-10G-ER 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-ER draw?
Arista lists maximum power of 1.5 W for the SFP-10G-ER. Check your switch's per-port power budget for dense deployments.
