The Cisco QSFP-40G-SR4-S is a 40GBASE-SR4 QSFP transceiver module designed for short-range optical network connectivity over multi-mode fiber. This hot-swappable module is ideal for data center and enterprise network deployments requiring 40 Gigabit Ethernet speeds across short distances. We offer this transceiver module as part of our comprehensive Cisco networking components inventory.

The QSFP-40G-SR4-S transceiver module uses multi-mode optical fiber with an MPO connector interface for 40GBase-SR4 connectivity. Multi-mode fiber is optimized for shorter transmission distances, making this module suitable for intra-datacenter and campus network applications. Contact us today to confirm compatibility with your specific network infrastructure.

Yes, the QSFP-40G-SR4-S is a hot-swappable transceiver module, allowing you to insert or remove it from compatible Cisco network equipment without powering down the device. This design minimizes network downtime during maintenance or upgrades. Visit barcodesinc.com or contact us today for installation guidance and compatibility verification with your equipment.

SR4 (short-range) modules like the QSFP-40G-SR4-S use multi-mode fiber and are optimized for distances up to approximately 100 meters, while LR4 (long-range) modules use single-mode fiber and support distances up to 10 kilometers or more. The choice depends on your network topology—use SR4 for short intra-datacenter links and LR4 for longer campus or metro area connections. We offer both types to support diverse network architectures.

The QSFP-40G-SR4-S transceiver delivers 40 Gigabit Ethernet performance, providing high-speed data transmission for demanding enterprise and data center applications. This speed class is ideal for server interconnects, storage area networks, and backbone connectivity where bandwidth efficiency is critical. Available from us with full technical support for your deployment.

The QSFP-40G-SR4-S is designed for Cisco equipment with compatible QSFP ports, but specific compatibility depends on your switch model and firmware version. We recommend verifying your equipment's specifications before purchasing to ensure proper operation.
