HPE X142 40G QSFP+ LC LR4 SM Transceiver

Keep high-speed uplinks stable across longer fiber runs with the HPE X142 40G QSFP+ LC LR4 SM transceiver. Designed for single-mode deployments, it supports 40 GbE connectivity where distance, port density, and predictable optical performance are critical. The QSFP+ form factor fits modern aggregation and core switching environments, while the LC interface simplifies integration with existing fiber plant. This module is a strong fit for teams standardizing on Aruba infrastructure and looking to preserve throughput without moving to more expensive architecture changes. LR4 optics are commonly chosen for campus backbones, data center interconnects, and high-capacity switch-to-switch links where multimode options fall short. The result is a cleaner path to longer-reach connectivity with fewer compromises on link design. For procurement teams, this part earns its place by matching the performance profile expected in enterprise networks: 40G speed, single-mode reach, and a compact transceiver footprint that supports dense deployments. It is the kind of component that helps protect uptime, simplify expansion, and keep critical links aligned with the rest of the fabric.
