Arista SFP-10G-ERLBD-U-Arista | 10G SFP+ Transceiver, BiDi Single-Mode, 30km, LC

Q: What is the difference between the SFP-10G-ERLBD-U and SFP-10G-ERLBD-D?
A: The SFP-10G-ERLBD-U is the uplink variant transmitting at 1270nm and receiving at 1330nm, while the SFP-10G-ERLBD-D is the downlink variant with reversed wavelengths (Tx 1330nm, Rx 1270nm). They must be deployed in pairs at opposite ends of a link.

Q: What type of fibre is required for this transceiver?
A: This transceiver requires single-mode fibre (SMF) compliant with ITU-T G.652 standard. It uses a single fibre strand with BiDi technology, reducing fibre infrastructure requirements by 50% compared to traditional duplex solutions.

Q: Is Digital Diagnostics Monitoring supported?
A: Yes, this module supports DDM/DOM (Digital Optical Monitoring), enabling real-time monitoring of transmit power, receive power, temperature, voltage, and other optical performance parameters for proactive fault management.

Q: What Arista platforms support this transceiver?
A: This transceiver is compatible with Arista SFP+ platforms running EOS 4.21.3 or later. It is hot-swappable and integrates seamlessly with Arista switches featuring SFP+ ports.

Q: Are there any precautions for deployment?
A: Yes, optical attenuation is required for shorter links to prevent receiver overload and permanent damage. Ensure the optical input power remains within the specified receiver sensitivity range of 0 to -15 dBm.
