About Aruba 100G QSFP28 LR4 Optical Transceiver in Bangladesh
The Aruba 100G QSFP28 LR4 is a high-performance 100Gbps optical transceiver designed for long-reach Ethernet connectivity over single-mode fiber. The official Aruba product number is JL310A, identified by HPE Aruba Networking as the HPE Aruba Networking 100G QSFP28 LC LR4 10km SMF 2-strand Transceiver.
Using the QSFP28 form factor and 100GBASE-LR4 optical architecture, the JL310A provides 100Gbps Ethernet connectivity through four wavelength-multiplexed optical lanes. The optical channels operate across the 1294.53nm to 1310.19nm range and are carried over a duplex single-mode fiber connection.
The Aruba 100G LR4 uses a duplex LC UPC connector and supports a maximum transmission distance of 10 kilometers over compatible 9/125µm single-mode fiber. This makes it suitable for data center interconnects, campus backbones, enterprise aggregation, long-distance switch-to-switch connectivity, and other 100GbE applications requiring substantially greater reach than SR4 or CWDM4 optics.

Overview
The Aruba 100G QSFP28 LR4 optical transceiver provides 100Gbps Ethernet connectivity through a compact QSFP28 interface. It is designed for long-reach network links where conventional multimode 100G SR4 optics or shorter-reach CWDM4 solutions are not sufficient.
The LR4 architecture uses four optical wavelength channels that are multiplexed onto a duplex single-mode fiber connection. HPE Aruba specifies wavelength ranges of approximately 1294.53–1296.59nm, 1299.02–1301.09nm, 1303.54–1305.63nm, and 1308.09–1310.19nm for the four optical lanes.
With a maximum specified distance of 10 kilometers, JL310A is suitable for longer data center links, data center interconnects, campus backbone connections, enterprise network aggregation, and long-distance switch-to-switch connectivity.
The module uses a duplex LC UPC connector and 9/125µm single-mode fiber. Proper fiber polarity, connector type, optical budget, and link loss must be verified before deployment.
HPE Aruba specifies Digital Optical Monitoring (DOM) support and a 3.5W power requirement for JL310A.
