Arista compatible QSFP-100G-LRL4 Description
QSFP-100G-LRL4 is Arista’s part number for a reduced-power-budget 100GBASE-LR4 QSFP28 transceiver. Arista markets this as the “LR4 Lite” variant, intended for single-mode fiber links where the full 100GBASE-LR4 power budget is not needed. EdgeOptic’s compatible replacement is built on our 100G-QSFP28-10 platform and delivers the full 100GBASE-LR4 specification, providing the standard 10 km reach over G.652 single-mode fiber rather than the reduced distance Arista specifies for the LRL4 variant.
The 100GBASE-LR4 specification uses four LAN WDM channels at 1295.56, 1300.05, 1304.58, and 1309.14 nm, each carrying 25G NRZ modulation for an aggregate data rate of 103.1 Gbps. The optical interface is duplex LC/UPC per IEEE 802.3ba. The module conforms to the QSFP28 MSA and supports DDM monitoring of per-lane Tx/Rx optical power, module temperature, supply voltage, and laser bias current. Operating temperature range is 0°C to 70°C.
Arista’s QSFP-100G-LRL4 appears in transceiver compatibility matrices for the 7050X/X2/X3/X4 series, 7060X/X2/X4/X5 series, 7280R/R2/R3 series, and 7500R/R2/R3 series. These span Arista’s core data center leaf/spine, campus, and chassis-based switching platforms. EdgeOptic codes the module with Arista-recognized EEPROM, so EOS reports it as a supported transceiver without warnings. DDM telemetry is accessible through the “show interfaces transceiver” CLI command and through SNMP IF-MIB and ENTITY-MIB polling for integration with network monitoring systems.
Because EdgeOptic builds the QSFP-100G-LRL4 replacement on the full 100G-QSFP28-10 platform, the compatible exceeds the original Arista LRL4 power budget. Network teams replacing LRL4 modules get a drop-in optic that covers link distances from short intra-building runs up to the full 10 km, removing the need to stock separate LR4 and LRL4 inventory. Don’t confuse the QSFP-100G-LRL4 with the QSFP-100G-LR4; the latter is Arista’s full-budget LR4 SKU with a different ordering code. EdgeOptic produces separate compatible SKUs for each Arista part number, with distinct EEPROM profiles matched to the vendor’s transceiver database. In large data center fabrics where hundreds of 100G optics are deployed across leaf and spine tiers, consolidating on the full-specification EdgeOptic compatible simplifies procurement and spare management.
EdgeOptic backs this compatible with a lifetime warranty and CE/RoHS certification. For Arista platform questions or bulk pricing, contact our sales team
Frequently Asked Questions
Does the EdgeOptic QSFP-100G-LRL4 replacement exceed Arista’s original LRL4 reach?
Yes. Arista’s LRL4 is a reduced-power-budget variant of 100GBASE-LR4, intended for shorter single-mode links. EdgeOptic’s compatible is built on the 100G-QSFP28-10 platform with full LR4 optics, supporting the standard 10 km reach over G.652 single-mode fiber.
What is the difference between Arista QSFP-100G-LRL4 and QSFP-100G-LR4?
The QSFP-100G-LRL4 is Arista’s reduced-power-budget (“LR4 Lite”) version for shorter links. The QSFP-100G-LR4 is the full-budget LR4 with standard 10 km reach. Both use the same four LAN WDM wavelengths and 25G NRZ modulation. EdgeOptic produces separate compatible SKUs for each with distinct EEPROM profiles.
Which Arista platforms accept the QSFP-100G-LRL4?
The QSFP-100G-LRL4 is listed for the 7050X/X2/X3/X4, 7060X/X2/X4/X5, 7280R/R2/R3, and 7500R/R2/R3 series platforms. EdgeOptic’s compatible works across these same Arista switching families with full EOS support.
