QSFP-40G-SR-BD=

This Cisco QSFP-40G-SR-BD= transceiver module enables high-speed 40 Gigabit Ethernet connections over multi-mode fiber. It's commonly used in data centers and enterprise networks where short-reach, high-bandwidth links are needed between switches, servers, or storage devices.

Built for environments that require fast, reliable optical communication, this module allows IT professionals to extend their network capacity without major infrastructure changes. Network engineers often find it valuable for upgrading existing fiber runs while maintaining compatibility with MPO cabling.

Key Features

• Designed for 40GBase-SR4-BiDi operation on multi-mode fiber
• Works with 850nm wavelength to optimize short-distance transmission
• Offers a maximum reach of 150 meters on OM4 fiber cables
• Compact QSFP+ form factor with MPO connector for easy integration
• Compatible with Cisco switches and other standard QSFP+ ports

These transceivers are typically deployed in busy data centers where space and speed matter. They help maintain fast data flows across racks and equipment closets without needing new fiber infrastructure. The module's ability to handle 40Gb/s speeds over multi-mode fiber suits it well for layering network capacity in existing setups.
