The QSFP-40G-SR-BD Quad Small Form-Factor Pluggable (QSFP) bi-directional transceiver module is a high-performance module designed for 40Gbps connectivity over OM3 or OM4 multimode fiber (MMF). It utilizes two 20Gbps channels which transmit and receive on the same strand at the same time, allowing for 40Gbps of bidirectional connectivity over existing 10G duplex LC MMF cabling infrastructure. It supports link lengths of up to 100 meters over OM3 and up to 150 meters over OM4/OM5 MMF. The module is hot-swappable, compliant with QSFP+ SFF-8436 and IEEE 802.3ba standards, and features Digital Diagnostics Monitoring (DDM/DOM).
