## Long description

The Cisco QSFP-100G-SR4-S is a 100G Ethernet network transceiver module with a QSFP interface designed for short-reach multimode fiber links. The module supports high-density 100 Gigabit Ethernet connections in data centers and enterprise aggregation layers, offering a compact form factor that fits QSFP ports and enables parallel fiber optics for multi-lane transmission up to 150 meters over compatible multimode fiber.
Advantages
This transceiver provides reliable 100G performance with a QSFP interface that supports hot-pluggable installation and easy integration into existing switches and routers that accept QSFP modules. The multimode fiber support and short-reach capability reduce latency and simplify cabling in densely populated rack environments. Its compact design helps preserve port density while offering consistent optical performance for high-throughput applications.
Suitable for
 Data center aggregation and top-of-rack uplinks
 High-performance computing clusters requiring 100G links
 Switch-to-switch or switch-to-server short-reach connections within large campuses
 Environments using multimode fiber for short-distance backbone links
Key specifications
 Interface type: QSFP (Quad Small Form-Factor Pluggable)
 Nominal data rate: 100 Gigabit Ethernet
 Optical medium: multimode fiber
 Maximum reach: up to 150 meters over compatible multimode fiber
 Form factor: QSFP compact transceiver
 Transmission: parallel multi-lane optics for aggregated 100G throughput
How to use
Install the module into a compatible QSFP port on a switch or router while the device is powered on or off, following the host equipment vendor's hot-plug guidelines. Connect the multimode fiber trunk cable with the appropriate MPO/MTP connector or patching arrangement that matches the module's parallel lanes. After physical installation, verify link status through the network device interface and configure port settings such as speed and VLANs as required by your network design. Monitor optical diagnostics and link statistics to confirm expected performance.
Usage recommendations
Use high-quality multimode fiber with the correct fiber type and connector polarity to achieve the specified reach; verify compatibility with the switch or router platform documentation. Keep transceiver optical interfaces covered when not connected and follow ESD precautions during handling. For optimal performance in data center environments, pair the transceiver with suitable patch panels and maintain fiber cleanliness to prevent signal degradation.
