HPE 746960-001

BladeSystem C-Class 40 Gb QSFP+ MPO SR4 Transceiver module

The HPE 746960-001 is a high-bandwidthQSFP+ Transceiver module crafted for HPE BladeSystem C-Class enclosures. Supporting 40GBASE-SR4 protocol, it operates over multimode fiber and provides full-duplex 40 Gb/s connectivity via four parallel 10 Gb channels, ideal for backbone links or Virtual Connect interconnects. Featuring compact hot-swappable design and MPO connector with integrated Digital Diagnostics Monitoring (DDM/DOM), it lets administrators observe real-time optical metrics like temperature, voltage, and signal power. Engineered for reliable, high-speed communication in blade and rack environments, this module delivers enterprise-class performance at a cost-effective price. 

Features

Built on 40GBASE-SR4 standards, the 746960-001 transceiver leverages four independent 10 Gb full-duplex lanes, aggregating to 40 Gb/s over multimode fiber. It supports reliable transmission up to 100 m on OM3 and up to 150 m on OM4 fiber using MPO connector technology—ideal for high-density interconnects within blade chassis or data center racks. Compatible with QSFP+ MSA and IEEE 802.3ba standards, the module integrates seamlessly into HPE Virtual Connect fabrics and BladeSystem interconnects, allowing safe hot-swappable installation—even under power—minimizing maintenance downtime.  Digital Diagnostics Monitoring (DOM) provides insights into key optical parameters like transmit/receive power, laser bias, voltage, and temperature—crucial for proactive network health checks. Manufactured to top safety standards, it meets CE, RoHS, and SFF-8436, with wide operating temperatures from 0 to 70 °C. Together with low-power consumption (roughly 1.5 W), it suits dense and eco-efficient setups. Refurbished units often come with a 90-day warranty, while new units may carry a lifetime warranty. 

Advanced Options

Despite its compact size, the HPE 746960-001 delivers robust 40 Gb performance for mission-critical environments. With four parallel lanes, it ensures full-line rate 40 Gb/s throughput—ideal for aggregating interconnects in blade or dense rack configurations. The inclusion of DOM allows continuous monitoring of optical power levels and device health, enabling network teams to identify and resolve degradation before it affects operations.  Compliance with key industry standards and wide thermal tolerance contribute to dependable long-term reliability.
