200Gbps High-Speed Networking

The Cisco QSFP-200G-FR4-S is designed for 200 Gigabit Ethernet connectivity, providing four times the nominal bandwidth of a 50GbE connection and twice the bandwidth of a 100GbE connection.

This high bandwidth makes the module suitable for modern data center networks where large volumes of east-west traffic, storage traffic, virtualization traffic and application data must be transferred efficiently.

200GBASE-FR4 Optical Technology

The QSFP-200G-FR4-S follows the 200GBASE-FR4 optical configuration. Cisco specifies four CWDM wavelengths that carry the 200GbE signal through the optical interface. :contentReference[oaicite:4]{index=4}

The four specified nominal wavelengths are 1270nm, 1290nm, 1310nm and 1330nm. Multiplexing and demultiplexing of these optical wavelengths are handled within the transceiver. :contentReference[oaicite:5]{index=5}

2km Transmission Distance

The Cisco QSFP-200G-FR4-S supports link lengths of up to 2km over duplex single-mode fiber. This makes it suitable for data center interconnects and other network deployments where a 200G link must extend beyond the shorter distances typically associated with multimode SR4 optics. :contentReference[oaicite:6]{index=6}

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

Duplex LC Connector

The module uses a duplex LC optical connector. Duplex LC connectivity provides separate transmit and receive optical paths through a compact connector design.

Cisco specifies PC or Ultra-Physical Contact (UPC) patch cords for supported connections. :contentReference[oaicite:7]{index=7}

Single-Mode Fiber Support

The QSFP-200G-FR4-S is designed for duplex single-mode fiber (SMF). Cisco identifies the supported fiber as SMF with a G.652 core specification in its optical documentation. :contentReference[oaicite:8]{index=8}

Using the appropriate single-mode fiber infrastructure helps maintain the optical characteristics required for reliable 200G transmission over the specified 2km distance.

Four CWDM Wavelengths

The 200G-FR4 optical architecture uses four wavelength channels at 1270nm, 1290nm, 1310nm and 1330nm. Each optical lane carries part of the overall 200GbE signal. :contentReference[oaicite:9]{index=9}

The wavelengths are multiplexed into the duplex fiber connection within the module, allowing a high-bandwidth 200G connection to operate over a standard duplex SMF infrastructure.

QSFP56 Form Factor

The Cisco QSFP-200G-FR4-S uses the QSFP56 form factor. QSFP56 is designed for high-speed 200G networking and provides a compact optical interface suitable for high-density switch and router deployments.

Its compact form factor allows network operators to deploy high-bandwidth interfaces without requiring the physical space of multiple lower-speed optical modules.

200GAUI-4 Electrical Interface

The module uses a 200GAUI-4 electrical host interface and supports CEI-56G-VSR-PAM4 electrical signaling. Cisco specifies 200GAUI-4/CEI-56G-VSR-PAM4 for the QSFP-200G-FR4-S. :contentReference[oaicite:10]{index=10}

This electrical architecture enables the host networking platform to communicate with the four-lane optical interface of the FR4 transceiver.

Host FEC

Cisco specifies that FEC is performed on the host platform for the QSFP-200G-FR4-S. :contentReference[oaicite:11]{index=11}

Therefore, the host switch, router, NIC or other networking platform must provide the appropriate FEC functionality for the supported 200G 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 the average receive power per lane is specified from -8.2dBm to 4.7dBm. :contentReference[oaicite:12]{index=12}

Optical link performance depends on the complete fiber path, including patch cords, connectors, splices and patch panels.

Data Center Interconnect

The 2km reach of the QSFP-200G-FR4-S makes it useful for connecting network infrastructure across data center facilities, equipment rooms and other locations where a 200G single-mode fiber link is required.

It can be used for switch-to-switch, router-to-switch and other compatible 200GbE optical connections.

Enterprise Network Applications

The Cisco QSFP-200G-FR4-S can be deployed in high-bandwidth enterprise networks where 200GbE connectivity is required between core, aggregation and data center networking devices.

• Core network uplinks
• Data center spine connections
• Leaf-to-spine links
• High-speed aggregation
• Storage network connectivity
• Cloud infrastructure

Operating Temperature

The Cisco 200G QSFP56 optical modules are specified for an operating temperature range of 0°C to 70°C. Storage temperature is specified from -40°C to 85°C. :contentReference[oaicite:13]{index=13}

The transceiver should be installed in a networking platform that provides appropriate airflow and environmental conditions within the specified operating range.

Mechanical Specifications

Cisco specifies the module dimensions with pull tab as approximately 8.5 x 18.4 x 78.3/93.3mm (H x W x D). The maximum weight for optical modules is 100g. :contentReference[oaicite:14]{index=14}

Cisco Platform Compatibility

Cisco states that its QSFP modules are supported on Cisco switches, routers and NICs as well as selected third-party host platforms and NICs. Compatibility should be checked against the Cisco Transceiver Modules Compatibility Matrix and the exact host platform before installation. :contentReference[oaicite:15]{index=15}

Optical transceiver compatibility can depend on the switch or router model, software release, port type and transceiver support policy. Always verify the exact Cisco platform before ordering.

Compatibility Considerations

Before installing the Cisco QSFP-200G-FR4-S, verify:

• Host device supports QSFP56 200G optics
• Host port supports 200GBASE-FR4
• Cisco software and firmware support the transceiver
• Duplex LC SMF infrastructure is available
• Fiber link budget is within the supported optical limits
• Host-side FEC is supported
• Operating temperature remains within specification

Do not assume that every QSFP56 port supports every 200G optical module. Confirm compatibility with the exact Cisco switch, router, NIC or other host platform.
