HPE JL308 

Aruba JL308A 40 Gb QSFP+ LC BiDi Transceiver module

The HPE Aruba JL308A is a bi‑directional QSFP+40 GbE Transceiver module designed to support high-density, short-reach multimodefiber connectivity (150 m over OM4 or ~100 m over OM3). Utilizing LC duplex connectors and dual-wavelength VCSEL optics (850 nm upstream, 900 nm downstream), it transmits full-duplex at 40 Gbps using only two fiber strands. Ideal for Aruba switch environments requiring high-speed links without needing MPO cabling, the JL308A is optimized for data center uplinks, spine-leaf switches, or high-speed aggregation layers—delivering robust performance in space-constrained fiber infrastructure

Features

The module supports 40GbE via XLPPI electrical interface and operates using dual bi-directional channels: 20 Gbps transmit and receive on each fiber strand using two distinct wavelengths. This approach avoids the need for traditional MPO patch cords, working instead with standard duplex OM3/OM4 fiber cabling—simplifying upgrade paths in legacy 10G fiber plants Built-in Digital Optical Monitoring (DOM) gives administrators real‑time insight into transmit/receive power, voltage, and temperature. With power consumption at +3.3 V and compliance to QSFP+ MSA and 40GBASE‑SR‑BD standards, it provides a compact yet reliable solution for short-range high-bandwidth links.

Advanced Options

Engineered for dependable high-throughput connectivity, the JL308A ensures full-duplex 40 Gbps performance using standards-based bi-directional optical technology. Each fiber strand handles 20 Gbps in each direction utilizing wavelength multiplexing, avoiding MPO cabling complexity while maintaining cable plant efficiency
