Arista Networks QSFP-40G-PLRL4 QSFP Transceiver

Arista QSFP-40G-PLRL4 is a QSFP+ 40 Gigabit Ethernet transceiver that delivers four 1310 nm lanes in parallel for 40GBASE-PLRL4 links, using an MPO/MTP interface to connect to single‑mode fiber. Identified as XVR-00013-02 in Arista’s part numbering, this PLRL4 module is designed for short‑reach to intermediate distances on SMF, with typical link lengths up to 1 kilometer. It is listed in Arista's transceiver portfolio alongside other 40G XVR modules and is documented in Arista data sheets as part of the QSFP-40G-PLRL4 family. Ideal for data-center uplinks that require high‑density 40G connections over a single fiber ribbon, the device supports four 1310 nm wavelengths to carry 40G data efficiently across compatible Arista switches. The MPO/MTP interface enables a single connection into the switch’s QSFP cage, simplifying cabling in spine-and-leaf architectures while preserving performance and interoperability with other QSFP+ PLRL4‑capable platforms.
