HPE JH233A X142 40G QSFP+ MPO eSR4 300M XCVR

Detailed Specifications

The HPE X142 40G QSFP+ MPO eSR4 300M Transceiver is an optical module designed to deliver high-bandwidth 40 Gigabit Ethernet connectivity for data center and enterprise networking environments. Its primary purpose is to provide a reliable, short-to-medium-range link between switches, routers, and servers over multimode fiber, effectively addressing the need for higher-density aggregation and interconnects. This module is ideal for top-of-rack or end-of-row switch deployments where high-speed uplinks are critical for eliminating network bottlenecks and supporting bandwidth-intensive applications. This QSFP+ transceiver utilizes 850nm wavelength vertical-cavity surface-emitting laser (VCSEL) technology to transmit data reliably up to 300 meters over OM3 multimode fiber. It employs a standard MPO-12 connector, enabling a straightforward and high-density cabling infrastructure. The module's performance is optimized for 40GbE applications, providing the throughput necessary for modern server virtualization, cloud computing, and large-scale data transfer, ensuring consistent, low-latency performance for critical east-west traffic patterns within the data center. Engineered for seamless integration, this hot-swappable transceiver plugs into any QSFP+ compliant port, such as those found on the HPE FlexFabric switch series. Its plug-and-play design simplifies network upgrades and maintenance, allowing for rapid deployment without significant downtime. Management is handled by the host device's operating system, which provides diagnostic monitoring capabilities to track key performance metrics. The compact form factor allows for high port density, enabling scalable and cost-effective network expansion.
