Description

This Arista 10GBASE-ERBD SFP+ transceiver is the uplink (-U) end of a bidirectional 10GbE link. It carries 10 Gigabit Ethernet up to 40km over a single strand of G.652 single-mode fibre, so it suits campus, metro and data-centre interconnects where fibre strands are scarce.

The module transmits at 1270nm and receives at 1330nm through a simplex LC connector. Transmit power is 0 to 5.0 dBm and receive power is -9 to -21 dBm. Maximum power consumption is 1.5W, which is higher than the 1W of standard SFP+ optics. No licence or subscription is required.

The -U module must be deployed as a matched pair with the SFP-10G-ERBD-D at the far end, which transmits at 1330nm and receives at 1270nm. It is supported on Arista EOS from release 4.21.3 in SFP+ ports on supported Arista platforms.

Features

- Single-fibre bidirectional (BiDi) operation halves the fibre strands needed compared with duplex optics
- Reaches 40km over a single strand of single-mode fibre
- Hot-swappable, to maximise uptime and simplify serviceability
- Deployed as a matched pair with SFP-10G-ERBD-D (Tx 1330nm / Rx 1270nm)
- Proper optical attenuation is required on shorter links to protect the receiver

Warranty

All products sold by XS Network Tech include a 12-month warranty on both new and used items. Our in-house technical team thoroughly tests used hardware prior to sale to ensure enterprise-grade reliability.

FAQs

Q: Which module do I need at the other end of the link?
A: Pair this -U module with an SFP-10G-ERBD-D at the far end. The -D module transmits at 1330nm and receives at 1270nm, which matches this module's 1270nm transmit and 1330nm receive.

Q: Does it need a licence or subscription?
A: No. No licence or subscription is required.

Q: How much power does it draw from the host port?
A: A maximum of 1.5W, drawn from the SFP+ port. This is higher than the 1W of standard SFP+ optics, so check the port power budget on your platform.

Q: Which Arista software release supports it?
A: The minimum EOS release is 4.21.3. It fits SFP+ ports on supported Arista platforms, so check the Arista Transceiver and Cable Guide for your model.

Q: Do I need attenuation on short links?
A: Yes. Proper optical attenuation is required on shorter links to protect the receiver from the module's transmit power.
