Aruba (HPE) JL310A Compatible 100GBASE-LR4 QSFP28 Module, 10km SMF (ArubaOS-CX)

EdgeOptic's JL310A compatible is an Aruba (HPE) coded 100GBASE-LR4 QSFP28 transceiver, built on our 100G-QSFP28-10 hardware platform. JL310A is the HPE Aruba Networking ordering code for the 100G QSFP28 LC LR4 10 km SMF 2-strand transceiver, also marketed as the HPE Networking X151 in some HPE catalogues. The module targets the ArubaOS-CX switching family, and each unit ships with Aruba-recognised EEPROM values pre-programmed so the optic identifies on Aruba CX chassis through the standard transceiver detection path. The JL310A is the spare-parts and new-port-build SKU for 100G LR4 client connectivity on these platforms; the JL275A is the separate HPE FlexNetwork-coded sibling and is not interchangeable against an Aruba CX BOM line.

Aruba lists JL310A against 100G QSFP28 ports on the CX 8320, CX 8325 and CX 8360 switching platforms. The exact set of qualified line cards and ArubaOS-CX releases varies by chassis and software train. Verify the JL310A reference against HPE's transceiver compatibility matrix for the specific ArubaOS-CX platform and software release before deployment. The Aruba-coded EEPROM identification means the standard transceiver detection path on ArubaOS-CX recognises the module without configuration of the third-party-optics override on these qualified hosts.

Optically the module conforms to IEEE 802.3ba 100GBASE-LR4 Clause 88. Four LAN-WDM channels at 1295.56, 1300.05, 1304.58 and 1309.14 nm each carry 25.78125 Gbps NRZ on a single duplex LC SMF pair for an aggregate 103.125 Gbps line rate. The optical path loss budget is 6.3 dB on G.652 single-mode fiber, supporting 10 km on typical metro and campus plant. The QSFP28 form factor follows MSA SFF-8665, with hot-plug operation on a live ArubaOS-CX chassis and DDM/DOM telemetry through SFF-8636 exposing per-lane TX and RX optical power, module temperature, supply voltage and laser bias current. Module power draw is roughly 3.5 W.

The JL310A and the JL275A are separate HPE ordering codes for different switch ecosystems. JL310A is coded for ArubaOS-CX (the modern HPE campus switching line: CX 8320, CX 8325, CX 8360). JL275A is coded for HPE FlexNetwork (the legacy AOS-S environment). The optical specification is the same 100GBASE-LR4 / 10 km / SMF profile, but the EEPROM identification is platform-specific and the modules are not substitutable across ecosystems. Confirm which HPE OS the target chassis runs before ordering. The duplex LC connector accepts standard SMF patch cords, and the commercial 0 to 70 °C operating temperature range covers typical campus and POP environments.
