HPE 747698-B21 40GbE QSFP+ SR4 Optical Transceiver
Overview
The HPE 747698-B21 is a high-density, hot-pluggable QSFP+ (Quad Small Form-factor Pluggable) optical transceiver designed for 40 Gigabit Ethernet data links. This module is specifically engineered for reliable, short-range data communication over multi-mode fiber optic cables, making it an ideal solution for interconnecting switches, routers, and servers within data centers and enterprise campus networks. It addresses the need for increased bandwidth and port density, enabling the aggregation of multiple 10GbE links into a single, efficient 40GbE connection. At its core, the transceiver operates on the 40GBASE-SR4 standard, utilizing four parallel 10 Gb/s data lanes to achieve an aggregate data rate of 40 Gb/s. It employs a nominal wavelength of 850nm and an MPO connector interface, which is standard for multi-lane fiber applications. This technical design allows for dependable connectivity over distances up to 300 meters on OM3 multi-mode fiber and up to 400 meters on OM4 fiber, providing robust performance for top-of-rack, middle-of-row, or end-of-row switch deployments. Designed for seamless integration into compatible HPE networking hardware like the BladeSystem and c-Class platforms, the 747698-B21 simplifies network upgrades and maintenance. Its QSFP+ form factor is an industry standard for delivering 40GbE in a compact footprint, allowing for high port density on networking equipment. The module supports Digital Diagnostics Monitoring (DDM), giving network administrators real-time insight into critical operating parameters such as optical power and temperature.
