200Gbps High-Speed Connectivity

The Cisco QSFP-200G-LR4 provides a 200Gbps network interface for high-bandwidth networking environments. It is designed for applications where higher port bandwidth and efficient optical connectivity are required.

200G connectivity is suitable for modern data center switching, aggregation, backbone and high-performance infrastructure where large volumes of network traffic must be transported efficiently.

QSFP56 Form Factor

The QSFP-200G-LR4 uses the QSFP56 form factor. Cisco identifies QSFP56 as its 200Gbps transceiver platform, with products such as the QSFP-200G-SR4-S and QSFP-200G-SL4 listed within the 200G QSFP56 family. :contentReference[oaicite:2]{index=2}

The compact QSFP56 design supports high-density network deployments by allowing multiple high-speed optical ports to be installed within a relatively small physical footprint.

LR4 Long-Reach Optical Technology

LR4 is intended for long-reach optical connectivity over single-mode fiber. The Cisco QSFP-200G-LR4 configuration provides up to 10km reach, making it appropriate for extended optical links where shorter-reach multimode solutions are insufficient.

LR4 optical modules use multiple wavelengths to transport the high-speed optical signal over a duplex single-mode fiber connection.

1295–1309nm Wavelength

The QSFP-200G-LR4 operates across the approximately 1295nm to 1309nm optical wavelength range. This wavelength region is commonly used for long-reach single-mode fiber Ethernet applications.

The exact optical characteristics and operating limits should be checked against the module's official Cisco documentation and the specific hardware platform before deployment.

10km Optical Reach

The Cisco QSFP-200G-LR4 is designed for optical links up to 10km over single-mode fiber. This extended reach makes it suitable for connecting network infrastructure across larger facilities and distributed data center environments.

Actual link distance depends on fiber characteristics, optical loss, connectors, patch panels, splices and the complete optical link budget.

Duplex LC Connector

The QSFP-200G-LR4 uses a duplex LC optical interface. Duplex LC connectivity uses separate transmit and receive paths over a pair of single-mode fibers.

Use compatible single-mode LC fiber cabling and ensure correct polarity when installing the transceiver.

Single-Mode Fiber Connectivity

The LR4 transceiver is designed for Single-Mode Fiber (SMF). SMF is appropriate for longer-distance optical networking because it supports substantially greater transmission distances than typical multimode fiber configurations.

For a reliable 10km deployment, use suitable single-mode fiber infrastructure and verify the total optical loss against the module's specified link budget.

PAM4 Modulation

The 200G QSFP56 LR4 architecture uses PAM4 signaling to achieve high data rates while maintaining a compact optical module form factor. PAM4 uses four signal levels to carry more information per symbol than conventional two-level signaling.

The use of PAM4 is an important characteristic of modern 200G optical networking technology.

200G Ethernet Applications

The Cisco QSFP-200G-LR4 is designed for high-bandwidth Ethernet networking. Typical applications include:

• Data center interconnects

• Distributed data center links
• Telecommunications infrastructure

Data Center Interconnect

The 10km reach of the QSFP-200G-LR4 makes it particularly suitable for data center interconnect applications where network equipment may be separated by significant physical distances.

It can provide high-bandwidth optical connectivity between compatible switches, routers or other network devices across a facility or interconnected infrastructure.

High-Density Networking

The QSFP56 form factor allows network equipment manufacturers to provide high port density while supporting 200Gbps per optical interface.

This makes the QSFP-200G-LR4 suitable for environments where rack space, switch port density and aggregate bandwidth are important considerations.

Optical Link Compatibility

Successful deployment requires compatible 200G optical ports, supported transceiver firmware and appropriate single-mode fiber infrastructure.

• Compatible 200G QSFP56 port
• Supported Cisco networking platform
• Single-mode fiber
• Duplex LC cabling
• Compatible optical wavelength
• Appropriate optical link budget

Always verify transceiver compatibility against the exact Cisco switch or router model before purchase.
