Aruba compatible JL743A Description
JL743A is the HPE Aruba part number for a 100GBASE-ER4 Lite QSFP28 transceiver. This EDGE compatible module matches the original Aruba specifications with EEPROM coded for ArubaOS-CX recognition. It operates over duplex single-mode fiber at four LAN-WDM wavelengths (1295.56, 1300.05, 1304.58, and 1309.14 nm), reaching up to 40 km with host FEC or 30 km without FEC.
The module uses EML transmitters and APD (Avalanche Photodiode) receivers, carrying four lanes at 25.78125 Gbps each for an aggregate 103.125 Gbps line rate. DDM/DOM provides real-time readings of TX/RX optical power, laser bias current, temperature, and supply voltage. Maximum power consumption is 4.5 W from a single 3.3 V supply. Operating temperature range is 0 to 70 °C.
The JL743A is supported on Aruba CX 8325-32C and 8325-48Y8C (AOS-CX 10.04.0030+), Aruba 8360 series, and Aruba CX 10000 platforms. On the 8325-32C, it is limited to ports 29-32; on the 8325-48Y8C, to ports 49, 51, 53, 55. Maximum four modules per switch due to thermal constraints. Our compatible module is coded for plug-and-play operation in ArubaOS-CX.
The JL743A is Aruba's equivalent of the Cisco QSFP-100G-ER4L-S and Arista QSFP-100G-ERL4. All three are 100GBASE-ER4 Lite QSFP28 modules with the same LAN-WDM wavelengths and reach. They are interoperable on the same fiber link, provided FEC is configured consistently on both ends.
Our compatible JL743A is CE and RoHS certified, QSFP28 MSA-compliant, and conforms to the 100G Lambda MSA (100GBASE-ER4 Lite). Before delivery, every module undergoes optical parameter measurement, connector cleanliness inspection, and EEPROM data validation testing.

Frequently Asked Questions
Which Aruba switches support the JL743A?
The JL743A is supported on Aruba CX 8325-32C, 8325-48Y8C (firmware AOS-CX 10.04.0030 or later), Aruba 8360 series, and Aruba CX 10000. It is limited to specific port positions and a maximum of four modules per switch due to thermal constraints. The 8400X does not support ER4L optics. Check the Aruba Transceiver Guide for your model's port mapping.
What is the Cisco or Arista equivalent of the JL743A?
The Cisco equivalent is QSFP-100G-ER4L-S and the Arista equivalent is QSFP-100G-ERL4. All three are 100GBASE-ER4 Lite QSFP28 modules with the comparable wavelengths, link budget, and reach. They are interoperable on the same fiber link.
Why is the JL743A limited to specific ports on the Aruba 8325?
The JL743A consumes up to 4.5 W, which is higher than standard LR4 optics (3.5 W). Aruba restricts ER4 Lite modules to ports with adequate thermal headroom to prevent overheating. On the 8325-32C, use ports 29-32. On the 8325-48Y8C, use ports 49, 51, 53, or 55.
Does the JL743A require FEC for 40 km reach?
Yes. Without host FEC, the module reaches approximately 30 km. With FEC enabled on the Aruba switch, reach extends to 40 km. Configure FEC at the interface level in ArubaOS-CX and ensure the remote end matches.
