FAQs

Q: Is the Arista SFP-25G-LR compatible with 10G networks?
A: Some Arista 25G transceivers support dual-rate 10G/25G operation, but the standard SFP-25G-LR is typically a fixed-rate 25G module. Check your switch platform documentation for rate support and consider dual-rate models if 10G compatibility is required.

Q: What type of fiber cable is required for this transceiver?
A: The SFP-25G-LR requires single-mode fiber (SMF) with duplex LC connectors. It operates at 1310nm wavelength and supports distances up to 10km over OS2 single-mode fiber.

Q: Does this module support digital diagnostics monitoring?
A: Yes, the SFP-25G-LR features DDM/DOM functionality, allowing real-time monitoring of optical power levels, temperature, transmit bias current, and supply voltage for proactive network management.

Q: Can I use third-party compatible transceivers with Arista switches?
A: Yes, Arista switches support industry-standard MSA-compliant transceivers that meet IEEE specifications. Third-party modules coded for Arista compatibility will function seamlessly when properly programmed and tested.

Q: What is the typical power consumption of this transceiver?
A: The SFP-25G-LR typically consumes less than 1.5W, making it suitable for high-density deployments. It operates on a 3.3V power supply with maximum current of 300mA.
