Cisco 100G QSFP28 100GbE Multi-Mode Transceiver Module

The Cisco QSFP-100G-SR1.2= is a QSFP28 optical transceiver that brings 100 Gigabit Ethernet connectivity to switches, routers, and network interface cards equipped with compatible ports. It delivers high throughput over multimode fiber, giving data centers, campus backbones, and high-performance computing clusters a straightforward way to scale bandwidth without re-architecting the network.

The module moves data at up to 100 Gbps through an LC/UPC connector and supports both OM4 and OM5 cabling. Two operating wavelengths, 855 nm and 908 nm, enable bidirectional transmission over distances up to 328 feet, making it well suited for rack-to-rack or row-to-row links. Because it is hot swappable, you can install or replace it without powering down equipment, which keeps critical applications online during maintenance or upgrades.

Digital Optical Monitoring provides real-time visibility into temperature, optical power, and signal quality, allowing administrators to identify issues before they affect performance. An operating range of 10 °C to 60 °C covers most controlled environments, and Cisco’s durable construction helps ensure long service life. Whether you are expanding a spine-and-leaf fabric, refreshing aggregation links, or connecting next-generation servers, this transceiver offers a reliable, manageable path to higher bandwidth.
