Use it to extend high-speed links between switches and routers.

## Long description

Cisco QSFP-100G-LR-S is a QSFP28 optical transceiver module engineered for 100 Gigabit Ethernet links over single-mode fiber. The module supports 100GBase-LR transmission up to 10 km and offers a four-lane 25 Gbps electrical interface in a compact, hot-pluggable QSFP28 form factor. It is intended for data center and metro network deployments where reliable, high-bandwidth connectivity is required between switches, routers and aggregation equipment.
Advantages
The transceiver provides high-density 100GbE connectivity with low power consumption and hot-pluggable operation for minimal service disruption during installation or replacement. It supports long-reach single-mode fiber links up to 10 km and is designed for compatibility with Cisco networking equipment, ensuring predictable interoperability and system-level performance. The QSFP28 form factor delivers four 25 Gbps lanes for flexible lane mapping and efficient use of port density in modern network architectures.
Suitable for
 Data center spine-to-leaf and switch-to-switch interconnects
 Metro aggregation and high-capacity uplinks
 Core router interconnections requiring 100GbE links
 Network upgrades aiming to extend single-mode fiber links up to 10 km
Key specifications
 Form factor: QSFP28, hot-pluggable
 Data rate: 100 Gigabit Ethernet (100GbE)
 Interface: four-lane 25 Gbps electrical
 Optical standard: 100GBase-LR for single-mode fiber
 Maximum reach: up to 10 km over single-mode fiber
 Wavelength: single-wavelength serial optics compatible with LR specification
 Power consumption: low-power QSFP28 class (typical values depend on operating conditions)
 Operational temperature: industrial data center ranges (refer to vendor documentation for exact values)
How to use
Install the module into a compatible QSFP28 port on a Cisco switch or router while the port is powered; the hot-pluggable design allows insertion and removal without shutting down the system. Connect single-mode fiber using appropriate LC duplex patch cords and ensure correct transmit/receive orientation. After installation, verify link status and speed through the device management interface and monitor optical parameters such as receive/transmit power to confirm proper operation.
Usage recommendations
Use certified single-mode fiber and high-quality LC patch cords, maintain proper fiber cleanliness, and follow equipment vendor guidance for transceiver compatibility and firmware versions. For optimal performance, verify link budgets and MPO/LC connector types when planning deployments up to 10 km and perform optical power checks during commissioning.
