Arista QSFP-40G-SRBD (XVR-10066-20) 40G QSFP+ SR BiDi Multi-Mode Optical Transceiver Module (850nm, Duplex LC, 150m)

Basic Parameter Table

Core Product Features

1. Original Arista BiDi 40G parallel multi-mode QSFP+ module, native compatible with all Arista 40G leaf-spine data center switches without firmware recognition errors.
2. 4-lane 850nm BiDi VCSEL laser architecture, realizes bidirectional transmission over duplex LC dual fiber, eliminates expensive MPO-12 ribbon fiber cable.
3. Standard duplex LC interface, directly matches existing LC multi-mode patch cords, ideal for upgrading legacy LC cabling data centers to 40G without rewiring.
4. Stable transmission: 100m over OM3 multi-mode fiber, 150m over optimized OM4 multi-mode fiber.
5. Complete DOM real-time optical monitoring: remotely read TX/RX optical power of each lane, module internal temperature and supply voltage for centralized data center O&M.
6. Standard hot-swappable QSFP+ packaging, supports online plug/unplug without powering off the switch.
7. Cost-saving short-reach 40G uplink solution for medium-density leaf-spine data centers, ToR rack aggregation and HPC clusters with legacy LC fiber infrastructure.

Application Scenarios

• Medium-density data center rack-to-rack 40G short-reach interconnection (existing LC fiber wiring)
• Top-of-Rack (ToR) switch 40G aggregation uplink without MPO ribbon trunk
• Small high-performance computing cluster parallel fiber interconnection
• Enterprise core network 40G multi-mode upgrade with original LC cabling system
