FAQs

Q: What is the maximum transmission distance of the SFP-25G-LR-E?
A: The SFP-25G-LR-E supports up to 2km over single-mode fiber without FEC for low-latency applications, or up to 10km with Forward Error Correction (FEC) enabled for extended reach.

Q: Is this transceiver compatible with 10G networks?
A: While the SFP-25G-LR-E is primarily designed for 25G operation, Arista 25G SFP28 ports typically support backward compatibility with 10G SFP+ optical modules on compatible platforms. Check your specific switch model for multi-rate support.

Q: What fiber type is required for this transceiver?
A: The SFP-25G-LR-E requires single-mode fiber (SMF) with OS2 specification and uses a duplex LC connector. It is not compatible with multi-mode fiber.

Q: Does this module support Digital Optical Monitoring?
A: Yes, the SFP-25G-LR-E includes Digital Optical Monitoring (DOM) functionality, providing real-time visibility into temperature, voltage, transmit power, receive power, and bias current for proactive link management.

Q: What applications is this transceiver best suited for?
A: The SFP-25G-LR-E is ideal for 25G Ethernet data centre interconnects, enterprise campus backbones, spine-leaf fabric architectures, and any application requiring 25Gbps throughput over single-mode fiber up to 10km.
