Product Description
The Juniper QSFPP-40GE-SR4-B is a Quad Small Form-Factor Pluggable Plus (QSFP+) transceiver module designed to deliver high-speed 40 Gigabit Ethernet (40GbE) connectivity. It adheres to the 40GBase-SR4 standard, which specifies the use of parallel optics over multi-mode fiber. This standard employs four independent transmit and four independent receive lanes, each operating at 10Gb/s, to achieve the aggregate 40Gb/s data rate. The transceiver utilizes an MPO (Multi-fiber Push-On) connector, typically a 12-fiber connector, to accommodate the parallel optical lanes. This makes it ideal for short-reach applications within data centers, such as connecting switches, servers, and storage devices. The SR4 designation indicates its suitability for standard multi-mode fiber, with typical reach capabilities of up to 100 meters on OM3 fiber or 150 meters on OM4 fiber. This QSFP+ module is a critical component for high-density networking environments where bandwidth demands are rapidly increasing. Its pluggable form factor allows for easy installation and hot-swapping, simplifying network deployment and maintenance. The QSFPP-40GE-SR4-B provides a high-performance, cost-effective solution for data center interconnects and other applications requiring massive data throughput over short distances.
