HPEJH232

(X142) 40 GbE LR4 QSFP+Transceiver module

The HPEJH232A (X142) is a 40 GbE QSFP+Transceiver module designed for long-range (LR4) connections over single-mode fiber using LC duplex connectors. Operates at 40 Gbps aggregate data rate×ideal for high-throughput uplinks in campus backbones, data centers, or between Aruba/HPEswitches equipped with QSFP+ ports. With a maximum reach of 10 km over SMF, this module supports digital diagnostic monitoring (DDM), hot-swappability, and seamless plug-and-play installation. Suitable for Aruba3810M, 2930M uplink modules, and other HPEnetworking products.

Features

Compliant with 40GBase-LR4 standards, the JH232A employs four CWDM lanes (1271/1291/1311/1331 nm) to transmit 40 GbE over LC-terminated SMF with a reach of up to 10 km. It features a robust optical budget (typically ≥ 9.7 dB), supporting optical link integrity under varied fiber attenuation conditions. The module supports DDM/DOM for real-time monitoring of temperature, voltage, and optical power. Compatibility with Arubauplink modules (e.g., JL078A, JL079A) and stack support on switches like the 2930M and 3810M is documented in Arubacompatibility matrix.

Advanced Options

Engineered for data-center-grade fiber connectivity, the JH232A ensures robust 40 GbE LR4 transmission with low power draw (~3.5 W) and stable thermal performance across 0-70 °C environments. Each CWDM lane provides precise power levels (Tx: -7 to +2.3 dBm; Rx sensitivity: -13.7 to +2.3 dBm) for reliable error-
