Arista QSFP-40G-PLR4 (XVR-10012-20) 40G QSFP+ PLR4 CWDM Single-Mode Optical Transceiver Module (1310nm, MPO-12, 10km)

Basic Parameter Table

Core Product Features

1.  Arista original 40GBASE-PLR4 CWDM single-mode QSFP+ optical module, native plug-and-play compatible with all Arista 40G core data center switches, no firmware recognition alarms.
2. Four-lane CWDM DFB laser design complying with 40GBASE-PLR4 standard, integrates four independent 10G channels to transmit total 40G traffic over one pair of OS2 single-mode ribbon fiber.
3. MPO-12 multi-fiber ribbon interface, optimized for high-density leaf-spine data center backbone cabling, greatly reduces cable volume in equipment racks.
4. Stable 10km long-distance transmission performance over OS2 single-mode fiber, ideal for cross-floor and inter-building 40G backbone links.
5. Complete DOM real-time diagnostic monitoring: remotely query each wavelength channel TX/RX optical power, module internal temperature and supply voltage for centralized data center O&M management.
6. Standard QSFP+ hot-swappable packaging, supports online hot plug/unplug without powering off the switch.
7. High-density long-reach 40G single-mode uplink solution for medium & large leaf-spine data centers with MPO trunk fiber wiring, multi-building campus core backbone construction.
