The QSFP+ module adopts 12 Fibers MTP/MPO Male connectors, reaching a link up to 150m over OM4 MMF (100m over OM3). This transceiver is compliant with IEEE 802.3 40GBASE-SR4 standard. At the same time, it is completely interoperable with all standard 40GBASE-SR4 interfaces. Digital diagnostics functions are also available via the I2C interface, as specified by the QSFP+ MSA, to allow access to real-time operating parameters. With its easy installation and hot-swappable design, this transceiver is ideal for various applications, including campus, data center, cloud deployments, high-performance computing environments, and interconnections between switches, routers, servers, and transport equipment. Because the QSFP-SR4-40G does not support 4x10G breakout connectivity, see QSFP-4×10G-SR for such applications.
