Hewlett Packard Enterprise JG325B 40G QSFP+ SR4 Transceiver

The Hewlett Packard Enterprise JG325B 40G QSFP+ SR4 Transceiver is a high-speed optical module that delivers 40 GbE uplink connectivity over short-range multimode fiber in HPE networks. Part of the X140 series, this QSFP+ SR4 transceiver uses an MPO/MTP connector and operates at 850 nm to support up to a 40 GbE data rate. It supports reach up to 100 m on OM3 multimode fiber and up to 150 m on OM4, with hot-swap capability for easy installation in compatible equipment. It is designed for compatibility with HPE switches, routers, and other network devices that provide QSFP+ ports, making it suitable for core and aggregation switches, data center racks, and enterprise network environments requiring low-latency, high-bandwidth optical uplinks. Applications include switch uplinks, server interconnects, and storage networking within enterprise data centers, cloud platforms, and campus backbone networks.
