Description

The SFP-25G-MR-XSR-BCC is a drop-in compatible replacement for the Arista SFP-25G-MR-XSR. This dual-rate SFP28 transceiver operates at both 10G and 25G speeds and provides plug-and-play compatibility with Arista platforms running EOS 4.24.2 or later. - Complies with 10GBASE-CSR and 25GBASE-CSR standards, ensuring optical interoperability with 10GBASE-SR and 25GBASE-SR modules - SFP28 form factor with dual-rate operation: 25G up to 200m over OM3 or 300m over OM4, and 10G up to 300m over OM3 or 400m over OM4 - 850nm VCSEL wavelength with LC duplex connector for multi-mode fibre deployment - Digital Diagnostic Monitoring (DOM) support enables real-time access to transmit power, receive power, temperature, bias current, and supply voltage parameters - Extended reach capability designed for data centre spine-leaf fabrics, server connectivity, and network migration scenarios requiring longer MMF runs than standard SR optics

Features

• 10GBASE-CSR and 25GBASE-CSR compliance delivers optical interoperability with legacy 10GBASE-SR and standard 25GBASE-SR modules, enabling phased network upgrades without forklift replacement
• Extended reach architecture provides significantly longer MMF spans than standard 25GBASE-SR (70-100m limit), bridging the distance gap for existing data centre fibre infrastructure originally designed for 10G-SR
• Low-latency operation mode without Forward Error Correction (FEC) supports latency-sensitive workloads over short links up to 30m (OM3) or 50m (OM4), suited for high-frequency trading and HPC applications
• RS-FEC requirement at 25G for full-reach operation ensures robust link margins over extended MMF distances, with BASE-R FEC or no-FEC options available for shorter links
• Hot-swappable SFP28 interface allows field installation and replacement without system shutdown, with automatic rate negotiation when both ends support dual-rate operation
• Single-lane 25.78125 Gbps NRZ signalling at 25G and 10.3125 Gbps at 10G maintains backward compatibility with installed 10G SFP+ infrastructure while providing 2.5x throughput scaling path
• DOM functionality exposes real-time optical power budgets and module health telemetry via I2C interface per SFF-8472, enabling proactive link monitoring and troubleshooting without external test equipment

FAQs

Q: Will this work in place of the Arista SFP-25G-MR-XSR?
A: Yes. The SFP-25G-MR-XSR-BCC is a direct replacement based on the same 10GBASE-CSR and 25GBASE-CSR standards, SFP28 form factor, and dual-rate 10G/25G operation. It provides plug-and-play compatibility with Arista platforms and delivers identical reach and wavelength characteristics.

Q: Which Arista platforms support this transceiver?
A: This module is compatible with Arista platforms that feature SFP28 or SFP+ ports and run EOS version 4.24.2 or later. Arista's multi-rate SFP28 ports auto-negotiate between 10G and 25G operation. Consult Arista's Transceiver Module Group (TMG) Compatibility Matrix for specific platform support, as port capabilities vary across product families.

Q: What fibre types are required and what distances can I achieve?
A: This module requires OM3 or OM4 multi-mode fibre with LC duplex connectors. At 25G, reach is 200m over OM3 or 300m over OM4. At 10G, reach extends to 300m over OM3 or 400m over OM4. Low-latency mode (without FEC) reduces reach to 30m over OM3 or 50m over OM4. OM2 fibre is not supported.

Q: When is FEC required and how does it affect latency?
A: RS-FEC (Reed-Solomon Forward Error Correction) is required on the host port for full-reach 25G operation over OM3/OM4, adding approximately 250ns latency. For links under 30m (OM3) or 50m (OM4), low-latency mode disables FEC entirely. At 10G, BASE-R FEC adds 80ns or can be disabled depending on link margin. FEC selection impacts both reach and latency.

Q: Can I connect this module to legacy 10G-SR optics, and are there any precautions?
A: Yes, when operated at 10G this module optically interoperates with standard 10GBASE-SR SFP+ transceivers. However, on very short links (typically under 10m), optical attenuation may be required to prevent overloading the 10G-SR receiver, as this extended-reach module has higher transmit power than standard 10G-SR. Check the Arista Optics-to-Optics Interoperability Matrix for attenuation requirements on your specific link distance.
