200Gbps High-Speed Networking

The QSFP-200G-FR4-S provides a 200Gbps Ethernet interface for high-bandwidth data center networking. It is designed for environments where higher port density and greater bandwidth are required between switches, routers, servers and other network infrastructure.

Its 200GBASE-FR4 architecture is particularly useful for data center interconnects and high-speed switch-to-switch links where single-mode fiber is preferred.

200GBASE-FR4 Optical Technology

The Cisco QSFP-200G-FR4-S uses four CWDM optical wavelengths to transmit the 200Gbps Ethernet signal. Cisco specifies wavelengths of 1270nm, 1290nm, 1310nm and 1330nm. Multiplexing and demultiplexing of these four wavelengths are managed within the transceiver. Cisco

This architecture enables a 200Gbps connection over a duplex single-mode fiber pair rather than requiring a large parallel-fiber MPO connection.

2km Transmission Distance

The QSFP-200G-FR4-S supports link lengths of up to 2 kilometers over compatible single-mode fiber. This makes it suitable for many data center, campus and infrastructure interconnection scenarios where distances exceed the reach of short-range multimode optics.

Actual achievable distance depends on fiber quality, connector losses, patch panels, insertion loss and the complete optical link budget.

Duplex LC Connector

The transceiver uses a duplex LC optical connector. Cisco specifies PC or UPC connector types for supported patch cords and does not support APC patch cords for this module. Cisco

Duplex LC connectivity uses two optical fibers, with one fiber dedicated to transmission and the other to reception.

Single-Mode Fiber Support

The QSFP-200G-FR4-S is designed for single-mode fiber and Cisco specifies G.652 fiber for the module.

Single-mode fiber is appropriate for longer-distance optical networking and provides the optical characteristics required by the 200GBASE-FR4 implementation.

Optical Wavelengths

The four wavelengths operate on the CWDM grid and are multiplexed within the transceiver. Cisco specifies these four wavelengths for the QSFP-200G-FR4-S. Cisco

QSFP56 Form Factor

The QSFP-200G-FR4-S uses the QSFP56 form factor. QSFP56 is designed for high-speed 200Gbps networking and provides a compact optical interface suitable for modern high-density data center equipment.

The Cisco module has maximum dimensions of approximately 8.5 × 18.4 × 78.3/93.3mm, depending on the pull-tab configuration. Cisco lists a maximum optical-module weight of 100 grams. Cisco

200GAUI-4 and PAM4 Electrical Interface

The QSFP-200G-FR4-S uses a 200GAUI-4 electrical interface and supports the CEI-56G-VSR-PAM4 electrical standard. Cisco specifies the module for 200GE operation using this high-speed electrical architecture. Cisco

FEC Performed by Host Platform

Cisco specifies that FEC is performed on the host platform for the QSFP-200G-FR4-S. The networking device hosting the transceiver therefore handles the forward error correction function required by the link.

Optical Link Budget

Cisco specifies a maximum supported insertion loss of 4dB for the QSFP-200G-FR4-S. The documented average transmit power per lane ranges from -4.2dBm to 4.7dBm, while average receive power per lane ranges from -8.2dBm to 4.7dBm. Cisco

For reliable deployment, the complete optical path should be evaluated, including fiber length, patch cables, connectors, patch panels and other sources of insertion loss.

Operating Temperature

The QSFP-200G-FR4-S is specified for an operating temperature range of 0°C to 70°C. This makes it suitable for standard data center and controlled networking environments.

Storage temperature for Cisco's 200G QSFP56 optical modules is specified from -40°C to 85°C. Cisco

Data Center Applications

• 200G switch-to-switch connections
• Data center interconnects
• High-speed aggregation networks
• Core and distribution networking
• Server and network infrastructure
• High-performance computing environments
• Enterprise data center networks
• Short-distance metro or campus interconnection where supported

Compatibility

Cisco states that its QSFP modules are supported on Cisco switches, routers and NICs as well as third-party host platforms and NICs, subject to the applicable transceiver compatibility matrix. Cisco

Before purchasing, verify that the target Cisco device specifically supports QSFP-200G-FR4-S and that the required software and firmware versions are compatible with the module.

QSFP-200G-FR4-S vs QSFP-200G-SR4-S

The two modules serve different optical environments. Cisco specifies the FR4 module for 2km duplex SMF, while the SR4-S module is intended for shorter multimode-fiber connections. Cisco
