Description

The Arista SFP-10G-ERBD-U is a 10GBASE-ERBD BiDi SFP+ transceiver engineered for extended-reach single-fiber deployments over OS2 single-mode fibre, achieving up to 40km. Designed as the uplink module in a matched BiDi pair, it transmits at 1270nm and receives at 1330nm over a single LC simplex interface — halving fibre consumption compared to conventional duplex transceivers. This makes it ideal for metro and campus interconnects, data centre links, and any environment where fibre strand availability is limited.

The SFP-10G-ERBD-U supports DDM/DOM for real-time optical monitoring and is hot-swappable for zero-downtime maintenance. It is MSA-compliant and requires Arista EOS 4.21.3 or later. This module must be deployed in a matched pair with the complementary downlink variant (SFP-10G-ERBD-D) at the far end; optical attenuation may be required on shorter links to protect the receiver.

Features

- Extended 40km reach over OS2 single-mode fibre for metro and campus links
- BiDi single-fiber design reduces fibre strand consumption by 50% vs duplex
- Uplink wavelength pair: Tx 1270nm / Rx 1330nm — must be matched with SFP-10G-ERBD-D at far end
- LC simplex interface simplifies patching and reduces cabling overhead
- DDM/DOM support enables proactive, real-time optical link health monitoring
- Hot-swappable for live insertion and removal without network disruption
- MSA-compliant for broad interoperability across compatible platforms
- Note: optical attenuation may be required on links shorter than the minimum launch power threshold

FAQs

Q: What is the difference between the SFP-10G-ERBD-U and SFP-10G-ERBD-D?
A: The SFP-10G-ERBD-U is the uplink module, transmitting at 1270nm and receiving at 1330nm. The SFP-10G-ERBD-D is the complementary downlink module with the opposite wavelength pair. They must always be deployed together at each end of the single-fibre link — one uplink module at each end would not function correctly.

Q: Can the SFP-10G-ERBD-U be used with non-Arista switches?
A: This transceiver is MSA-compliant, which means it is designed to meet industry-standard SFP+ specifications. However, Arista qualifies and supports it specifically within the Arista EOS ecosystem (minimum EOS 4.21.3). Compatibility with third-party platforms should be validated against that vendor's supported transceiver list.

Q: Why might I need optical attenuation with this transceiver?
A: On very short fibre runs, the transmitted optical power may exceed the receiver's maximum input power tolerance, potentially causing signal errors. In such cases, an inline optical attenuator should be inserted to reduce the power level to within the receiver's specified operating range.

Q: Does this transceiver support digital diagnostics monitoring?
A: Yes. The SFP-10G-ERBD-U supports DDM/DOM (Digital Diagnostics Monitoring / Digital Optical Monitoring), allowing network administrators to monitor real-time parameters such as transmit power, receive power, temperature, voltage, and laser bias current directly from the switch management interface.

Q: Can I purchase this transceiver in Australia through IP Trading?
A: Yes. IP Trading (iptrading.com.au) stocks Arista transceivers and ships across Australia. The SFP-10G-ERBD-U is backed by a 1-Year Limited Hardware Warranty, with optional Next Business Day and 4-Hour Advance Hardware Replacement support available. Contact the IP Trading team for volume pricing and availability.

Q: What type of fibre cable is required for the SFP-10G-ERBD-U?
A: This transceiver requires OS2 single-mode fibre (SMF) terminated with an LC simplex connector. Unlike standard duplex transceivers that use two fibre strands, the BiDi design uses only one strand per link, so a single LC simplex patch lead is all that is required between the two ends.
