HP compatible JL437A Description
JL437A is HPE's ordering code for the x130 10G SFP+ LC SR transceiver, a 10GBASE-SR module rated for 850 nm multimode operation. HPE lists the JL437A in the Aruba networking portfolio, where it replaces the older JD092B part numbers. The module carries the same optical parameters across all three SKUs: 850 nm VCSEL transmitter, PIN photodiode receiver, duplex LC/UPC connector, and a minimum 6.1 dB optical power budget.
Reach follows standard 10GBASE-SR geometry: 300 m over OM3 and 400 m over OM4 multimode fiber at 10.3125 Gbps. The data rate range spans 1.25 Gbps through 10.3125 Gbps, so the module also negotiates at 1G Ethernet on dual-rate ports common in Aruba CX switches. The operating temperature is 0°C to 70°C, consistent with commercial-grade indoor switch deployments.
Target platforms for the JL437A include Aruba CX 6300M, 6300F, 6400, and 8325 series switches, as well as legacy HPE FlexNetwork 5130, 5700, and 7900 platforms that accept x130-series optics. On Aruba CX (AOS-CX firmware), transceiver identification is reported through show interface transceiver with vendor name, part number, and serial stored in the SFF-8472 EEPROM fields. The CX 8325 in particular is common in campus and leaf/spine designs where 10G SR links serve as server uplinks or inter-switch trunks.
DDM diagnostics per SFF-8472 expose Tx power, Rx power, laser bias, temperature, and Vcc readings to the switch management plane. These metrics integrate with AOS-CX monitoring and can be polled via SNMP or REST API for proactive link health tracking. The Aruba CX REST API (v10.x firmware) also exposes transceiver diagnostics as JSON endpoints, making automated inventory and health checks straightforward in scripted environments.
EdgeOptic's compatible JL437A is manufactured on the 10G-SFP-300 platform, meeting IEEE 802.3ae 10GBASE-SR and SFF-8431/SFF-8432 MSA requirements. The EEPROM is coded with HPE-recognized vendor identifiers for seamless acceptance on Aruba CX and FlexNetwork hardware. The module reports correctly in show interface transceiver detail, populating vendor name, part number, and calibrated DDM fields without triggering unsupported-optic warnings.
Frequently Asked Questions
Does the JL437A replace the older JD092B on Aruba CX switches?
JL437A is HPE's current x130 10G SFP+ LC SR ordering code and supersedes the JD092B. Both carry the same 10GBASE-SR optical parameters (850 nm, 300 m OM3, 6.1 dB budget). The JL437A EEPROM profile is qualified for Aruba CX 6300, 6400, and 8325 platforms as well as legacy FlexNetwork hardware. EdgeOptic's compatible uses the JL437A EEPROM coding, so it is recognized on both current CX and older FlexNetwork switches.
Is the JL437A compatible supported on Aruba CX 6300 and CX 6400 series?
Yes. The CX 6300M, 6300F, and 6400 accept x130-series SFP+ modules in their 10G slots. AOS-CX firmware reports the transceiver identity through show interface transceiver, reading vendor name, part number, and calibrated DDM fields from the SFF-8472 EEPROM. EdgeOptic's compatible is coded to match HPE's expected JL437A vendor identifiers, so no unsupported-optic warnings appear on these platforms.
