## Summary description

The Cisco QSFP-100G-LR4-S is a high-performance network transceiver module designed for long-range data transmission. It features a QSFP interface and supports data rates of up to 100 Gbps over distances of up to 10 km using single-mode fiber. This module is ideal for data centers and enterprise networks requiring high bandwidth and reliability.

## Long description

The Cisco QSFP-100G-LR4-S is a network transceiver module engineered for long-range 100 Gigabit Ethernet links over single-mode fiber. With a QSFP form factor, the module supports aggregated data throughput of up to 100 Gbps and is intended for use in environments where reliable high-bandwidth connectivity between switches, routers and transport equipment is required across distances up to approximately 10 km.
Advantages
This QSFP transceiver offers long-reach capability on single-mode fiber with compact QSFP packaging that enables high-density port deployment. It supports standardized 100G-LR4 optical line rates and is designed for interoperability with compatible networking equipment. The module delivers predictable optical performance and low power consumption relative to older multi-module solutions, simplifying rack-level cabling and reducing the number of required interfaces for high-capacity links.
Suitable for
Data center interconnects between aggregation and core switches
Enterprise campus backbone links requiring 100 Gbps bandwidth
Metro and campus fiber runs up to 10 km over single-mode fiber
High-density switch or router ports where QSFP form factor is needed
Key specifications
Interface type: QSFP (Quad Small Form-Factor Pluggable)
Nominal data rate: 100 Gbps
Optical type: LR4 for single-mode fiber
Maximum reach: up to 10 km on standard single-mode fiber
Wavelength configuration: four-channel coarse wavelength division multiplexing
Connector type: duplex LC (requires appropriate patching)
Form factor: QSFP for high-density installations
Typical power consumption: optimized for QSFP-class modules (varies by system)
How to use
Install the module into a compatible QSFP slot on the host switch or router while the device is powered according to the equipment vendor’s instructions. Connect single-mode fiber using LC duplex patch cords and ensure correct polarity. Verify the link status via the host device management interface and confirm optical power and diagnostics if supported. When removing the module, follow hot-swap procedures if supported by the chassis and handle the transceiver by the housing to avoid contamination of optical interfaces.
Usage recommendations
Use clean, certified single-mode fiber and LC patch cords to maintain optical performance; inspect and clean connectors before mating. Confirm compatibility with the host device and check link parameters (power, BER, and diagnostics) during commissioning. For long-term reliability, operate the module within the equipment’s thermal and power specifications and avoid excessive mechanical stress on fiber cables.
