HPE 720187-B21 BladeSystem C-Class 40 Gb QSFP+ MPO SR4 Transceiver Module
Overview
The HPE 720187-B21 is a QSFP+ (Quad Small Form-factor Pluggable Plus) transceiver module engineered to deliver reliable, high-speed 40 Gigabit Ethernet connectivity. Designed specifically for demanding data center and enterprise networking environments, this module is ideal for short-reach interconnects within and between racks, such as linking servers in HPE BladeSystem platforms to top-of-rack switches. It solves the critical need for a dense, high-bandwidth connection over multi-mode fiber infrastructure. At its core, the transceiver operates on the 40GBASE-SR4 standard, utilizing four independent 10 Gb/s data lanes in each direction to achieve an aggregate throughput of 40 Gbps. This parallel optics technology transmits over multi-mode fiber using an 850nm wavelength, providing a cost-effective solution for high-performance links up to 150 meters. The use of a standard MPO connector enables higher port density and simplifies cable management in complex, high-performance computing environments. This hot-swappable module integrates seamlessly into corresponding QSFP+ ports on compatible HPE switches and BladeSystem interconnects. Its plug-and-play design minimizes network disruption during installation or replacement. The unit supports Digital Diagnostics Monitoring (DDM), giving network administrators real-time visibility into critical operating parameters like optical power and temperature, which is essential for proactive network maintenance and troubleshooting.
