HP compatible 720190-B21 Description
EdgeOptic's 720190-B21 compatible is an HPE-coded version of the EdgeOptic 40G-QSFP-10 multi-vendor 40GBASE-LR4 transceiver. It is a QSFP+ module built to IEEE 802.3ba Clause 87, carrying 40 Gigabit Ethernet over four CWDM lanes at 1271, 1291, 1311 and 1331 nm, reaching 10 km over single-mode fiber through a duplex LC interface.
The DFB transmitter holds each lane between −6 and +3 dBm. A PIN photodiode receiver delivers −12.6 dBm per-lane sensitivity with a +3 dBm overload point, giving a 6.6 dB link budget across the full 10 km span. The module runs over the 0 to 70 °C commercial range with full DOM telemetry for live optical monitoring.
This compatible is coded for HPE BladeSystem c-Class server blade infrastructure. Verify the specific interconnect module and enclosure against the HPE transceiver compatibility guide. EdgeOptic writes HPE-recognized EEPROM so the interconnect accepts the optic as a qualified module. Don't confuse the 720190-B21 with HPE's FlexFabric or Aruba campus-switch LR4 part numbers, which carry different HPE ordering codes. Verify the port assignment against the enclosure transceiver table during commissioning.
Backed by 15+ years of EdgeOptic compatibility engineering across vendor optical platforms. Ships next business day from EU stock with a lifetime warranty.
Frequently Asked Questions
How does the HPE 720190-B21 differ from JG661A and JH232A?
All three are HPE 40GBASE-LR4 QSFP+ optics with the same four-lane CWDM optics, LC duplex and 10 km reach, but they carry different HPE ordering codes tied to different platform families. The 720190-B21 is the BladeSystem c-Class ordering code, while JG661A and JH232A are different HPE 40GBASE-LR4 codes tied to other HPE platform families. Order against the code your HPE platform's port list specifies.
