Arista QSFP-40G-SRBD (XVR-10066-20) 40GBASE-BiDi QSFP+ Transceiver, Refurbished
Warranty: Lifetime
Quick answer: The Arista QSFP-40G-SRBD (XVR-10066-20) is a genuine Arista 40G QSFP+ BiDi optic that runs 40 Gigabit Ethernet over a single pair of multimode fibers with a duplex LC connector, up to about 100 m on OM3 and 150 m on OM4. Resilient Tec sells it refurbished, with a lifetime warranty and free US shipping from Knoxville, TN.
Condition: Refurbished
The Arista XVR-10066-20 (QSFP-40G-SRBD) is a genuine Arista 40GBASE-BiDi (Bi-Directional) QSFP+ optical transceiver. It enables full-duplex 40Gb/s (2x 20Gb/s per fiber) over a single pair of duplex multimode fiber using LC connectors, ideal for short-reach data center links where fiber reuse saves time and cost.
Great for Arista switches in enterprise data centers, campus backbones, and high-bandwidth aggregation needing reliable 40G performance without infrastructure changes.
Key Features:
- 40 Gigabit Ethernet throughput (40GBASE-SR BiDi / 40GBASE-SRBD)
- Bi-Directional design: Transmit and receive on the same duplex LC pair (no parallel MPO required)
- Reach: Up to 150m over OM4 multimode fiber (or ~100m on OM3)
- Wavelength: 850nm / 900nm (BiDi wavelengths for bidirectional operation)
- Hot-pluggable QSFP+ form factor with digital diagnostics monitoring (DOM)
- Low power consumption for efficient, high-density deployments
- Compliant with QSFP+ MSA and IEEE 802.3ba standards
Compatibility:
- Arista 7000 Series switches (e.g., 7050X, 7060X, 7280R, 7500 series) and other platforms with 40G QSFP+ ports
- Standard duplex LC multimode fiber (OM3/OM4 recommended for max reach)
- Interoperable with compatible 40G BiDi modules from other vendors in mixed environments (verify per switch EOS version)
- Often used for 40G links in legacy cabling setups or as an upgrade path from 10G/25G
Frequently Asked Questions
Why choose BiDi over 40G SR4?
BiDi runs 40G over existing duplex LC multimode cabling from 10G links, so you avoid installing MPO trunks.
Does the far end need the same optic?
Yes. Use a 40G BiDi optic on both ends of the link; it will not link with a 40G SR4.
Is it genuine Arista?
Yes, an Arista-branded module (part XVR-10066-20), sold refurbished.
What warranty and shipping come with it?
Resilient Tec's lifetime warranty. US standard shipping is free with no minimum, and orders typically arrive in 3 to 5 days.
