## Summary description

The Cisco QSFP-100G-SR1.2 is a fiber optic transceiver module designed for high-speed data transfer at 100000 Mbit/s. It features a QSFP interface and is ideal for data centers and high-performance computing environments.

## Long description

The Cisco QSFP-100G-SR1.2 is a 100 Gbit/s fiber optic transceiver module with a QSFP form factor designed for short-reach multimode fiber links. It supports high-density port deployments in data centers and high-performance computing environments, providing a compact solution for aggregation and spine-leaf topologies. The module is engineered to meet industry-standard electrical and optical interfaces for seamless interoperability with compatible switches and optical equipment.
Advantages
This QSFP transceiver delivers 100 Gbit/s throughput in a small, hot-pluggable QSFP package, enabling high port density and simplified cabling. It is optimized for short-reach multimode fiber applications, offering stable optical performance and predictable power consumption. The module supports vendor interoperability and standard management features via the QSFP interface, making it suitable for rack-scale deployments where space and energy efficiency are important.
Suitable for
Data center aggregation and spine/leaf fabric links
High-performance computing clusters requiring high bandwidth
Top-of-rack switch uplinks over multimode fiber
Short-reach connections within campus or enterprise wiring closets
Key specifications
Nominal data rate: 100 Gbit/s
Form factor: QSFP (quad small form-factor pluggable)
Optical medium: multimode fiber (short-reach)
Wavelength and optics class: short wavelength for multimode operation
Interface: four-lane electrical and optical aggregation
Operational temperature range suitable for standard data center environments
Hot-pluggable design for in-service installation and replacement
How to use
Install the transceiver into a compatible QSFP port on a switch or router while the host device is powered on or off, following the equipment manufacturer’s instructions for hot-pluggable modules. Connect appropriate multimode fiber cables with matching connectors (for example, MPO/MTP where applicable) and verify link status through the host device management interface. Monitor module diagnostics and performance counters provided by the host to ensure optical levels and lane alignments are within expected ranges.
Usage recommendations
Use certified multimode fiber with proper patching and polarity to achieve optimal short-reach performance. Ensure the transceiver’s optical specifications match the fiber type and link distance. For reliable operation, observe handling precautions such as using dust caps when the module or cables are unplugged and avoiding excessive bending of fiber cables.
