The QSFP-40G-SR-BD Transceiver is a Cisco 40GBASE-SR-BiDi optical module designed for high-speed data center and enterprise networks using multimode fiber. It enables bidirectional transmission over a duplex MMF link, which reduces fiber usage while maintaining full 40 Gbps throughput. Furthermore, this transceiver supports short-reach connections up to 100 m on OM3 and up to 150 m on OM4 or OM5 fiber, making it ideal for modern data center architectures. Additionally, the QSFP+ form factor is hot-swappable, allowing installation or replacement without network downtime. Consequently, maintenance becomes easier and operational efficiency improves. The module uses LC duplex connectors, ensuring compatibility with existing multimode fiber infrastructure. Moreover, it complies fully with IEEE 802.3ba and QSFP MSA standards, guaranteeing reliable interoperability across supported Cisco platforms. Power consumption remains low, which helps reduce heat generation in dense switch environments. However, despite its compact size, the module delivers stable and consistent optical performance under demanding workloads. The QSFP-40G-SR-BD Transceiver is commonly deployed in Cisco Nexus and Catalyst switches where scalable 40 Gigabit Ethernet connectivity is required.
