Description

This 40GBASE-BiDi QSFP+ transceiver is the receiver-only (-R) variant of the QSFP-40G-SRBD from Arista's 40GbE optics range. It uses duplex LC multimode fibre with dual-wavelength BiDi technology, reaching 100m over OM3 or 150m over OM4. Because it reuses existing duplex LC cabling rather than requiring parallel MPO fibre, it suits 40G deployments in data centre and campus switching environments.

Enquire with XS Network Tech for new or used pricing and availability.

Features

- Reuses existing duplex LC multimode fibre instead of requiring parallel MPO cabling
- Interoperates with third-party 40G BiDi transceivers over standard OM3/OM4 duplex MMF
- Hot-pluggable QSFP+ form factor for 40G ports on Arista switches
- BiDi dual-wavelength design carries traffic in both directions over a single fibre

Warranty

All products sold by XS Network Tech include a 12-month warranty on both new and used items. Our in-house technical team thoroughly tests used hardware prior to sale to ensure enterprise-grade reliability.
