Arista SFP-10G-LRL-Arista | 10G SFP+ Transceiver, Single-Mode, 1km, 1310nm, LC

Q: What is the difference between 10GBASE-LRL and 10GBASE-LR?
A: 10GBASE-LRL is designed for shorter reach applications up to 1km, while 10GBASE-LR supports up to 10km. Both use 1310nm wavelength and single-mode fiber, but LRL is optimized for lower-cost short-distance links with reduced optical budget requirements.

Q: Is this transceiver compatible with other vendor equipment?
A: While this is an Arista-branded SKU, 10GBASE-LRL transceivers using the same IEEE 802.3ae standard can optically interoperate with other vendors' LRL optics. However, for guaranteed compatibility and support, using vendor-approved transceivers is recommended.

Q: Does this module support Digital Diagnostic Monitoring?
A: Yes, the SFP-10G-LRL includes DDM/DOM functionality compliant with SFF-8472, allowing real-time monitoring of parameters such as temperature, voltage, transmit/receive optical power, and laser bias current through the network management interface.

Q: What type of fiber cable is required?
A: This transceiver requires OS2 single-mode fiber (SMF) with duplex LC connectors. Standard 9/125 micron single-mode fiber is appropriate for installations up to 1km distance.

Q: Can this transceiver be used in 25G SFP28 ports?
A: This is a 10G-only transceiver and is not dual-rate. It is designed for 10G SFP+ ports. When installed in 25G SFP28 ports on compatible platforms, it will typically operate at 10G speed if the port supports backward compatibility.
