## Summary description

Cisco QSFP-100G-DR-S is a QSFP28 100GBASE-DR optical transceiver designed for 100 Gbps Ethernet over single-mode fiber. It supports duplex LC connections and reaches up to 500 meters on SMF. Intended for data center and campus links, it enables high-speed uplinks and interconnects with low power consumption and hot-pluggable operation.

## Long description

The Cisco QSFP-100G-DR-S is a QSFP28 optical transceiver engineered for 100GBASE-DR Ethernet links over single-mode fiber. This module provides 100 Gbps throughput using a duplex LC interface and supports distances up to 500 meters on standard single-mode fiber. Designed for data center and campus interconnects, the transceiver is hot-pluggable and optimized for low power consumption and compact port density in switches and routers that accept QSFP28 form factors.
Advantages
The module offers high-bandwidth 100 Gbps connectivity in a compact QSFP28 form factor, enabling efficient uplinks and inter-rack connections. With support for duplex LC single-mode fiber and a 500 m reach, it simplifies short-range data center cabling while maintaining interoperability with standard 100GBASE-DR interfaces. Hot-pluggability reduces service disruption during replacement or upgrades, and the low power profile helps minimize thermal load in dense equipment racks.
Suitable for
 100 Gbps uplinks between switches and aggregation devices in data centers
 Interconnects within campus network buildings over single-mode fiber
 High-density port deployments requiring compact QSFP28 transceivers
 Replacement or expansion of existing 100GBASE-DR links
Key specifications
 Data rate: 100 Gbps (QSFP28)
 Interface: Duplex LC optical connector
 Fiber type: Single-mode fiber (SMF)
 Maximum reach: Up to 500 meters on SMF
 Standard: 100GBASE-DR Ethernet compatible
 Form factor: QSFP28 hot-pluggable
 Power: Low-power design suitable for dense deployments
How to use
Install the transceiver into a compatible QSFP28 port on a switch, router or network device while the host is powered on, using the hot-pluggable insertion procedure recommended by the equipment vendor. Connect duplex LC single-mode fiber patch cords to the module ensuring correct transmit/receive orientation. Verify link status on the host device and confirm that the interface negotiates 100 Gbps operation and the expected Ethernet standard. Monitor module temperature and optical alarm or diagnostic counters through the host’s management interface as needed.
Usage recommendations
Use clean, APC/PC-polished duplex LC connectors and follow proper fiber handling procedures to avoid signal loss. Ensure the host hardware supports 100GBASE-DR and QSFP28 transceivers. For optimal reliability, operate within the manufacturer’s recommended temperature and power specifications and perform link validation after installation.
