SFP-10G-LRL Arista Compatible 10G SFP+ LR Lite Module

SFP-10G-LRL is Arista’s part number for a reduced-power-budget 10GBASE-LR SFP+ transceiver. Arista markets this as “LR Lite,” intended for short single-mode fiber runs where the full LR power budget is unnecessary. Some Arista documentation rates the LRL at 1 km reach. EdgeOptic’s compatible replacement is built on our 10G-SFP-10 platform and delivers the full 10GBASE-LR specification, meaning the module supports up to 10 km over G.652 single-mode fiber rather than the reduced distance Arista specifies for the LRL variant.

The transmitter uses a 1310 nm DFB laser paired with a PIN photodiode receiver. Electrical and optical parameters conform to IEEE 802.3ae 10GBASE-LR, with mechanical compliance to SFF-8431 and SFF-8432. Digital diagnostics monitoring follows SFF-8472, providing real-time telemetry for Tx optical power, Rx optical power, temperature, supply voltage, and laser bias current. The connector interface is duplex LC/UPC. Link budget supports approximately 6.3 dB channel insertion loss at the rated 10.3125 Gbps line rate. Operating temperature range is 0°C to 70°C (commercial grade). The 10G-SFP-10 platform also supports dual-rate Fibre Channel operation at 4GFC (4.25 Gbps) and 8GFC (8.5 Gbps), so the same underlying module covers both Ethernet and storage network use cases where the host port supports FC data rates.

Arista’s SFP-10G-LRL appears in transceiver compatibility matrices for the 7050 series (7050TX, 7050SX, 7050QX variants), 7060 series, 7150 series, 7280 series (including the 7280R and 7280R2 line cards), and 7500 series modular chassis. EdgeOptic codes the module with Arista-recognized EEPROM, so EOS reports it as a supported transceiver without any unsupported-optic warnings. DDM telemetry is accessible through the EOS CLI (“show interfaces transceiver” command) and through standard SNMP IF-MIB and ENTITY-MIB polling.

Because EdgeOptic builds the SFP-10G-LRL replacement on the full-specification 10G-SFP-10 platform, the compatible exceeds the original Arista LRL power budget by a wide margin. Network teams replacing LRL modules get a direct drop-in optic that covers any single-mode link distance from a few hundred meters up to 10 km, eliminating the need to maintain separate LR and LRL inventory. For campus networks where Arista 7050 or 7060 switches connect across multiple buildings, the full 10 km reach removes distance concerns that the LRL’s reduced budget might introduce on longer fiber runs.

EdgeOptic backs this compatible with a lifetime warranty and CE/RoHS certification. For bulk pricing or platform-specific questions, contact our sales team
