Arista QSFP-40G-SR4 40Gbps 40GBASE-SR4 Optical Transceiver Module
The Arista QSFP-40G-SR4 is a 40Gbps short-range optical transceiver designed for high-speed Ethernet connectivity over multimode fiber. It supports 40GBASE-SR4 applications and is suitable for compatible Arista switches and other networking equipment requiring high-density 40Gbps optical connectivity.
The module operates at a nominal 850nm wavelength and uses a compact QSFP+ form factor with an MPO/MTP optical interface. It is designed for short-distance connections within data centers, enterprise networks, and other high-speed networking environments.
40GBASE-SR4 High-Speed Connectivity
The QSFP-40G-SR4 provides 40 Gigabit Ethernet connectivity using four parallel optical channels. Each lane carries a portion of the aggregate 40Gbps data stream, providing high-bandwidth connectivity between compatible network devices.
The SR4 architecture is optimized for short-range multimode fiber applications such as switch-to-switch and switch-to-server connections within data center environments.
850nm Multimode Fiber Transmission
The transceiver uses 850nm optical transmission and is designed for multimode fiber (MMF). The supported reach depends on the fiber grade, with OM3 and OM4 fiber providing different maximum transmission distances.
Parallel Optical Transmission
The 40GBASE-SR4 design uses four optical lanes to transmit the 40Gbps signal. This parallel architecture provides high-speed connectivity through the module's MPO/MTP fiber interface.
QSFP+ and MPO/MTP Interface
The compact QSFP+ form factor provides a high-density, hot-pluggable interface for compatible 40Gbps networking equipment. The module uses an MPO/MTP connector for parallel multimode fiber connectivity.
Short-Range Data Center Connectivity
The module is suitable for high-density connections between switches, servers, storage systems, and other compatible network equipment located within the same data center or nearby network facilities.
