Aruba JL737A | 10G SFP+ BiDi Transceiver, Single-Mode, 10km, LC

Q: What is the difference between the JL737A and JL738A transceivers?
A: The JL737A is the uplink variant transmitting at 1270nm and receiving at 1330nm, while the JL738A is the downlink variant with reversed wavelengths (TX 1330nm/RX 1270nm). A BiDi link requires one of each module deployed as a matched pair—one at each end of the fiber run—to enable bidirectional communication over a single fiber strand.

Q: What type of fiber cable does the JL737A require?
A: The JL737A requires standard single-mode fiber (SMF) 9/125 µm with LC simplex connectors. Because it is a BiDi transceiver, only a single fiber strand is needed per link, which reduces fiber infrastructure costs compared to traditional duplex transceivers.

Q: Which HPE devices are compatible with the JL737A?
A: The JL737A is designed for HPE Comware-based networking devices, including HPE FlexFabric and A-Series switches and routers that feature SFP+ slots. Always verify compatibility against your specific device's transceiver compatibility matrix before deployment.

Q: What are typical use cases for this BiDi transceiver?
A: This transceiver is ideal for campus and metro network uplink connections where fiber strand count must be minimized. Common applications include building-to-building connectivity, floor-to-core uplinks, and distributed enterprise campus networks requiring 10 Gbps throughput over distances up to 10 km.

Q: Does the JL737A support digital diagnostics monitoring?
A: Yes, the JL737A includes DDM/DOM (Digital Diagnostic Monitoring/Digital Optical Monitoring) support, enabling real-time monitoring of optical parameters such as transmit power, receive power, temperature, and voltage via the I2C interface for proactive network management.
