XVR-10081-21 Overview

The  Arista Networks is a 100GBASE-LRL4 QSFP28 optical transceiver designed for medium-range transmission over single-mode fiber (SMF).It uses LRL4 (Long Reach Lite) technology, which transmits 4 optical wavelengths (each 25Gbps) over a standard duplex LC fiber pair, delivering full 100Gbps throughput.With support for distances up to 2 kilometers, this module is ideal for data center interconnects and campus networks where reach requirements exceed DR (500m) but do not require full LR4 (10km).
