200Gbps High-Speed Connectivity

The QSFP-200G-ER4 provides 200Gbps-class optical connectivity for modern high-bandwidth networking environments.

Its high data rate is suitable for network aggregation, data center interconnects, cloud infrastructure and other applications where large volumes of data must be transferred between high-performance network devices.

40KM Long-Distance Optical Reach

The ER4 optical configuration is designed for extended-distance transmission over single-mode fiber, with a reach of up to 40km.

This makes the module suitable for connecting network infrastructure across extended campus environments, metropolitan locations and geographically separated data center facilities where the optical budget and network equipment support the required distance.

QSFP-DD Form Factor

The QSFP-DD form factor provides a compact pluggable interface for high-density 200G networking equipment.

QSFP-DD technology is widely used for high-speed data center networking because it enables high bandwidth while maintaining a relatively compact physical footprint.

Single-Mode Fiber Connectivity

The 200G ER4 architecture is intended for single-mode fiber (SMF). Single-mode fiber is appropriate for long-distance optical transmission and provides substantially greater reach than conventional multimode-fiber solutions.

Before deployment, verify that the switch or router supports the required fiber type, optical module and connector configuration.

Duplex LC Connector

The 200G ER4 optical architecture uses a duplex LC connector interface. The LC connector provides a compact duplex optical connection suitable for high-density network environments.

Use compatible single-mode duplex LC fiber cabling and ensure that both ends of the optical link use compatible transceiver specifications.

4-Channel LAN-WDM Architecture

200G ER4 optical modules use multiple optical wavelengths to carry the aggregate 200Gbps signal. Industry-standard 200GBASE-ER4 implementations use four LAN-WDM channels and multiplex them onto a single fiber pair.

The exact wavelength, modulation, FEC and optical-budget characteristics depend on the specific module implementation and host platform. Confirm the manufacturer's technical documentation for the exact Cisco-labeled unit before deployment.

Data Center Interconnect

The QSFP-200G-ER4 is well suited to data center interconnect applications where high bandwidth and extended optical reach are required.

• Inter-building data center links
• Campus data center connectivity
• Metropolitan network aggregation
• Cloud infrastructure interconnects
• High-speed backbone links

Enterprise Network Applications

Organizations can use 200G ER4 optical connectivity to connect high-performance switches, routers and aggregation platforms across longer single-mode fiber paths.

The extended optical reach can reduce the need for intermediate active network equipment when the optical budget, equipment compatibility and physical network design permit a direct link.

Compatibility Considerations

The QSFP-200G-ER4 should only be installed in networking equipment that explicitly supports the required 200G QSFP-DD optical module.

• Verify host device 200G QSFP-DD support
• Verify Cisco software and firmware compatibility
• Verify optical module support matrix
• Use compatible single-mode fiber
• Use duplex LC connectivity
• Verify optical reach and link budget
• Confirm transceiver compatibility at both ends

Optical modules can be platform-specific even when they use the same physical form factor. Always check the exact switch or router compatibility matrix before installation.

200G ER4 vs 200G Short-Reach Optics

Advantages of 200G ER4

• High 200Gbps bandwidth
• Extended optical reach
• Single-mode fiber compatibility
• Compact QSFP-DD form factor
• Duplex LC connectivity
• Suitable for data center interconnects
• Suitable for enterprise backbone networks
• High-density network deployment

Installation Considerations

Before installing the QSFP-200G-ER4, confirm the host device's supported transceiver list and required software version.

Clean all optical connectors before connection and use appropriate single-mode fiber cabling. Poor connector cleanliness, excessive fiber loss or an incompatible optical budget can prevent the link from establishing correctly.

For a 40km deployment, calculate the complete optical budget including fiber attenuation, connector losses, splice losses and any required engineering margin.

High-Speed Data Center Networking

As network traffic continues to grow, 200Gbps optical connectivity provides additional bandwidth for high-density server, storage, cloud and data center infrastructure.

The ER4 configuration extends this bandwidth over significantly longer distances than short-reach multimode optical modules, making it appropriate for selected inter-building and data center interconnect applications.
