Aruba JH231A (X142) 40GBASE‑SR4 QSFP+ Transceiver – 4‑Lane MPO/MMF, Up to 150 m

The HPE Aruba JH231A, also known as X142, is a genuine 40G QSFP+ transceiver tailored for 40GBASE‑SR4 over multimode fiber. It provides up to 150 m reach on OM4 and supports high-performance interconnects, especially suited for data centers and high-speed aggregation switching.

Features

Packing four 10 Gbps lanes aggregated into a single 40 GbE link, this module uses an MPO connector for compact fiber management. The Business suite includes DOM support compliant with.

Advanced Options

SFF-8472 for proactive diagnostics. Designed to be fully interoperable with HPE and Aruba switches (e.g., 5400R, 8320, 8400), it’s a reliable choice for high-throughput networks.

Product Key Features

  •  40 GBASE‑SR4 QSFP+: High-speed 40 GbE using 4 lanes × 10 Gbps over MMF

  •  MPO/MTP Connector: Compact 12-fiber MPO interface for streamlined connections 

  •  Up to 150 m Reach: Supports OM4 multimode fiber; roughly 100 m on OM3 

  •  Digital Diagnostics (DOM): Real-time monitoring of Tx/Rx power, temperature, voltage 

  •  Hot‑Swappable MSA-Compliant Module: Guaranteed compatibility with HPE/Aruba and standard QSFP+ ports
