Description

This 10GBASE-ERLBD BiDi SFP+ transceiver from Arista is built for 10GbE links of up to 30km over a single strand of single-mode fibre. It suits metro backhaul, campus and WAN interconnects, and data centre links where only one fibre strand is available between sites.

This is the uplink variant, transmitting at 1270nm and receiving at 1330nm over an LC simplex connector on G.652 single-mode fibre. Transmit power is 0 to 5.0 dBm and receive power is 0 to -15 dBm, with a maximum power draw of 1.5W supplied by the host SFP+ port. No licence or subscription is required.

It works in Arista switches with SFP+ ports running EOS 4.21.3 or later. The far end must use the matching SFP-10G-ERLBD-D downlink module (Tx 1330nm / Rx 1270nm). It is not interoperable with the 40km ERBD variants.

Enquire with XS Network Tech for new or used pricing and availability.

FAQs

Q: Which module do I need at the other end of the link?
A: You need the matching SFP-10G-ERLBD-D downlink module, which transmits at 1330nm and receives at 1270nm. Two uplink modules cannot be paired together.

Q: Does this transceiver need a licence or subscription?
A: No. It requires no licence or subscription and is powered by the host SFP+ port.

Q: Which switches and software versions does it work with?
A: It works in Arista switches with SFP+ ports running EOS 4.21.3 or later. Refer to the Arista Transceiver Guide for the per-platform compatibility matrix.

Q: How many fibre strands does it use?
A: It uses a single strand of G.652 single-mode fibre with an LC simplex connector, rather than a duplex pair.

Q: Is it interoperable with the 40km ERBD modules?
A: No. The 30km ERLBD modules are not interoperable with the 40km ERBD variants, so use matched ERLBD uplink and downlink modules.
