Product Description
The Arista QSFP-SR4 is a high-performance 40 Gigabit Ethernet (40GbE) transceiver designed for short-reach (SR) applications within data centers. It employs the QSFP+ (Quad Small Form-factor Pluggable Plus) form factor, which allows for high port density and efficient cabling. This transceiver utilizes an 850nm wavelength and operates over multimode fiber (MMF) using parallel optics technology. The SR4 designation indicates that the transceiver uses four parallel transmit and four parallel receive lanes, each operating at 10Gb/s, to achieve the aggregate 40Gb/s data rate. This requires an MTP/MPO connector, which can accommodate the multiple fiber strands needed for parallel transmission. The QSFP-SR4 supports distances of up to 100 meters over OM4 multimode fiber, making it ideal for switch-to-switch or server-to-switch connections within a data center rack or across rows. Arista Networks provides the QSFP-SR4 as a reliable and cost-effective solution for high-bandwidth connectivity in modern data center environments. It is engineered to meet stringent performance requirements, ensuring stable and efficient data transfer for demanding applications. This transceiver is a key component for building scalable and high-performance network infrastructures.
