Frequently Asked Questions
What is a 25GBASE-LR SFP28 transceiver used for?
A 25GBASE-LR SFP28 transceiver is used to enable 25 Gigabit Ethernet connectivity over long distances (up to 10 kilometers) in data center networks, campus area networks, and carrier-grade infrastructure. The LR designation indicates long-reach capability, making it ideal for connecting remote switches, storage systems, and server clusters without requiring intermediate repeaters.
Is the ENET 25GBASE-LR SFP28 compatible with Arista switches?
Yes, the ENET JH992A-ENC module is fully certified compatible with Arista 7050, 7060, 7160, and other 25G-capable Arista platforms. This Arista-compatible SFP28 provides OEM-equivalent performance at a lower cost, with identical form factor and electrical specifications ensuring plug-and-play installation.
What does DOM (Digital Optical Monitoring) do?
Digital Optical Monitoring (DOM) enables real-time monitoring of transceiver health metrics including optical transmit/receive power levels, module temperature, and voltage. This diagnostic capability allows network administrators to proactively identify signal degradation, fiber issues, or component failures before they impact network performance.
Can this 1310NM SFP28 module work with multimode fiber?
No, the 1310NM 25GBASE-LR SFP28 is optimized exclusively for single-mode fiber (SMF) transmission. Using it with multimode fiber will result in severe signal loss and transmission errors. Ensure your infrastructure uses ITU-T G.652D standard single-mode fiber cabling for optimal performance and maximum 10-kilometer reach.
