XVR-00013-02 Arista 40G 4x1310nm LR QSFP+ Optic Transceiver

XVR-00013-02 Overview

The is an Arista Networks 40GbE QSFP+ optical transceiver designed for long-range data transmission over single-mode fiber. It operates using four parallel optical lanes at 1310nm wavelength, delivering a total throughput of 40Gbps.This module follows the 40GBASE-PLR4/LR4 architecture, enabling transmission distances of up to 1 kilometer over SMF, making it suitable for data center interconnects and campus backbone deployments where longer reach is required beyond standard multimode solutions.Using an MPO-12 connector, the transceiver relies on parallel fiber transmission (4 transmit and 4 receive fibers), ensuring efficient high-bandwidth communication.t is commonly deployed in high-performance environments such as spine-leaf architectures, aggregation layers, and enterprise network backbones.
