About the Arista SFP-10G-ERBD-D
The Arista SFP-10G-ERBD-D is a hot-swappable SFP+ 10GBASE-ERBD (downlink) optical transceiver for 10 Gbps Ethernet over single strand single-mode, with a LC (single fibre) interface and reach of up to 40 km SMF. Bi-directional optics halve fibre usage, which matters on leased dark fibre and long metro routes. Typical uses: server access, top-of-rack and campus uplinks, storage networks and metro links.

SFP-10G-ERBD-D: frequently asked questions
What is the Arista SFP-10G-ERBD-D?
The Arista SFP-10G-ERBD-D is a SFP+ 10GBASE-ERBD (downlink) 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-ERBD-D?
Arista specifies the SFP-10G-ERBD-D for 40 km over a single strand of G.652 single-mode fiber. 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-ERBD-D?
Per Arista's published optics data sheet, the SFP-10G-ERBD-D transmits 0 to 5.0 dBm and receives −21 to −9 dBm.
Which fiber and connector does the SFP-10G-ERBD-D need?
The SFP-10G-ERBD-D uses a LC (single fibre) connector on single strand single-mode, at 1270 / 1330 nm (BiDi). BiDi optics must be installed as a matching pair.
Is the SFP-10G-ERBD-D 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-ERBD-U vs SFP-10G-ERBD-D: do I need both?
Yes. Fit the -U (uplink) at one end and the -D (downlink) at the other end of the single fibre strand. ERBD reaches 40 km; the ERLBD pair is the 30 km version.
Is your SFP-10G-ERBD-D 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-ERBD-D price in India and how do I order?
The Arista SFP-10G-ERBD-D 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-ERBD-D draw?
Arista lists maximum power of 1.5 W for the SFP-10G-ERBD-D. Check your switch's per-port power budget for dense deployments.
