Description

The Arista 10GBASE-ERLBD SFP+ transceiver carries 10GbE up to 30km over a single strand of single-mode fibre. This is the downlink (-D) end of a bidirectional (BiDi) pair, suited to campus, metro and data centre interconnects where only one fibre strand is available.

It uses a simplex LC connector with a 1270 / 1330nm wavelength pair over G.652 single-mode fibre. Optical transmit power is 0 to 5.0 dBm with a receive range of 0 to -15 dBm. Maximum power consumption is 1.5W, drawn from the host switch port, and the module operates at a case temperature of 0 to 70 C in the standard SFP+ form factor of 8.55 x 13.7 x 56.5 mm.

The downlink (-D) module must be paired with an SFP-10G-ERLBD-U uplink module at the far end of the link. It fits Arista SFP+ ports, and proper optical attenuation is required on shorter links to protect the receiver.

FAQs

Q: Which module does this transceiver pair with?
A: The downlink (-D) module must be paired with an SFP-10G-ERLBD-U uplink module at the far end of the single-fibre link. Two matching -D modules will not link.

Q: Does it need external power?
A: No. It draws a maximum of 1.5W from the host switch port, so no external power is required.

Q: What fibre does it require?
A: It runs over a single strand of G.652 single-mode fibre with a simplex LC connector, using a 1270 / 1330nm wavelength pair, for links up to 30km.

Q: Can I use it on short links?
A: Proper optical attenuation is required on shorter links to protect the receiver, as the transmit power is designed for medium-reach runs.

Q: What is it used for?
A: It suits medium-reach 10GbE links of up to 30km where only one single-mode fibre strand is available, such as campus, metro and data centre interconnects.
