HPE Aruba JL308A Compatible 40G QSFP+ LC BiDi 2-Strand Transceiver, 150m MMF

EdgeOptic's JL308A compatible is an HPE Aruba-coded version of the EdgeOptic BIDI-40G-QSFP-150 multi-vendor 40G BiDi QSFP+ transceiver. HPE markets the original part as the HPE Aruba Networking 40G QSFP+ LC Bidirectional 150m MMF 2-strand Transceiver, and the 2-strand label matters: the JL308A uses a duplex LC patch cable with two fibers, not the single-strand connection found on some 1GE BiDi optics. The link carries 40G Ethernet as two 20 Gbps full-duplex optical channels, one per fiber strand, at 850nm and 900nm, reaching up to 150m over OM3, OM4 or OM5 multimode fiber with a 2 dB average link budget. DDM and DOM diagnostics report per-lane launch power from -4 to 5 dBm and receiver sensitivity from -6 to 3 dBm through PIN photodiode receivers behind VCSEL transmitters. The module runs at 3.3V across a 0 to 70°C range and follows IEEE 802.3ba for the QSFP+ electrical and host interface, the QSFP+ MSA, SFF-8436, INF-8438i, CE and RoHS. The BiDi optical scheme itself is an industry MMF convention, not a distinct IEEE optical physical layer specification.

Aruba also sells the X142 40G QSFP+ MPO SR4 (JH231A) as a parallel-optics alternative to the JL308A. The X142 uses a 12-fiber MPO/MTP trunk and patch panel instead of duplex LC, so the choice often comes down to existing cabling: duplex-LC sites keep the JL308A path, while sites standardized on MPO trunking may prefer the X142. EdgeOptic's JL308A compatible is designed to match the OEM's form factor, wavelength plan and data rate, and carries EEPROM coded to register cleanly on Aruba switching hardware. Backed by 15+ years of EdgeOptic compatibility engineering across vendor optical platforms, it ships next business day from EU stock with a lifetime warranty.
