Arista SFP-50G-MR-SR-Arista | 50G SFP56 Dual-Rate Transceiver, 850nm MMF, 100m

Q: Is this transceiver backward compatible with 25G networks?
A: Yes, the SFP-50G-MR-SR is a dual-rate transceiver that can operate at both 50Gbps and 25Gbps, providing flexibility for network migration and mixed-speed environments. It can interoperate with standard 25GBASE-SR optics when operating at 25G.

Q: What fiber type is required for this transceiver?
A: This transceiver uses multimode fiber (MMF) with duplex LC connectors. It supports OM3 and OM4 fiber grades, with optimal performance on OM4 fiber achieving up to 100m reach at 50G and 400m at 25G.

Q: Can this transceiver be used in standard SFP28 ports?
A: This is an SFP56 transceiver designed for 50G-capable ports. While physically compatible with SFP28 ports, it requires 50G SFP or 50G-capable SFP-DD/DSFP ports to operate at the full 50Gbps data rate. Check your switch platform compatibility before deployment.

Q: Does this module support Digital Diagnostic Monitoring?
A: Yes, the transceiver includes DDM/DOM functionality, allowing real-time monitoring of key parameters including optical transmit and receive power, temperature, laser bias current, and supply voltage for proactive network management.

Q: What platforms support this 50G transceiver?
A: This transceiver is designed for Arista switches with native 50G SFP ports or 100G SFP-DD/DSFP ports operating in 50G mode. Refer to Arista's official transceiver compatibility guide for specific platform support and minimum EOS version requirements.
