Description
The Arista QSFP-40G-SRBD is a 40 Gigabit Ethernet (40GbE) QSFP+ (Quad Small Form-factor Pluggable Plus) transceiver module that employs Bi-Directional (BiDi) technology. This innovative approach allows for full-duplex communication over a single strand of multimode fiber (MMF) optic cable, utilizing different wavelengths for transmit and receive signals. It operates at 850nm and supports distances up to 100 meters, making it ideal for high-density data center interconnects. The module uses a duplex LC connector, but unlike standard SR transceivers, it transmits and receives on the same fiber pair, effectively doubling the fiber efficiency. This BiDi capability can simplify cabling infrastructure and reduce the number of fiber strands required for network deployments. Designed for Arista switches and other compatible networking equipment, the QSFP-40G-SRBD offers a high-performance and cost-effective solution for upgrading networks to 40GbE speeds. Its hot-pluggable design ensures ease of installation and maintenance without network downtime, supporting the dynamic needs of modern data centers.
