Detailed Specifications
HPE 841717-B21 40GBASE-BiDi QSFP+ Transceiver Module
Overview
The HPE 841717-B21 is a QSFP+ optical transceiver module engineered for high-bandwidth Ethernet links. It supports full 40 Gbps data rate using bidirectional (BiDi) transmission over duplex fiber, enabling high-speed connectivity for data-centre uplinks and dense switch interconnects. The compact plug-in design allows integration into compatible HPE/Aruba switches and minimizes fiber-cable infrastructure by reusing duplex links. It is appropriate for deployments such as leaf-spine fabrics, server-rack aggregation, and cloud-scale high-throughput fabrics requiring cost-efficient 40 Gb links.
