200Gbps High-Speed Connectivity

The Cisco 200G SR4 optical module provides 200GbE connectivity for modern high-bandwidth network environments. It is designed for applications that require substantially greater bandwidth than conventional 100GbE links.

The 200G Ethernet signal is transmitted over four parallel fiber pairs, with each optical lane operating at 50Gbps. Cisco specifies the electrical interface as 200GAUI-4 / CEI-56G-VSR-PAM4. :contentReference[oaicite:4]{index=4}

850nm Multimode Optical Transmission

The Cisco 200G SR4 module operates at a nominal wavelength of 850nm and is designed for multimode fiber connectivity.

The SR4 architecture uses parallel multimode optical lanes, making it suitable for short-reach data center applications where multimode fiber provides a practical and economical cabling solution.

MPO-12 Connector

The Cisco QSFP-200G-SR4-S uses an MPO-12 UPC optical connector. The MPO interface accommodates the parallel optical lanes required for 200GBASE-SR4 transmission. :contentReference[oaicite:5]{index=5}

Use compatible MPO-12 multimode fiber cabling and ensure correct polarity and fiber-pair configuration when installing the module.

OM3, OM4 and OM5 Fiber Reach

Cisco's official documentation specifies 70 meters over OM3 and 100 meters over OM4 and OM5 multimode fiber for the QSFP-200G-SR4-S. :contentReference[oaicite:6]{index=6}

2 x 100G Breakout

The Cisco 200G SR4 module can be used for breakout applications. Cisco specifies support for 2 x 100GBASE-SR2 breakout links. This allows a single 200G port to connect to two compatible 100G interfaces where the host platform and network configuration support the breakout operation. :contentReference[oaicite:7]{index=7}

4 x 50G Breakout

The module can also support 4 x 50GBASE-SR breakout applications. This can be useful when connecting a high-density 200G interface to multiple 50G network ports. :contentReference[oaicite:8]{index=8}

Data Center Networking

200G optical connectivity is well suited to modern data center environments where server, switch and storage traffic increasingly requires higher aggregate bandwidth.

The SR4 architecture is particularly appropriate for short intra-data-center connections between switches, servers and other network devices using multimode fiber.

High-Bandwidth Storage Networks

High-speed optical modules can be used as part of storage networking infrastructure where large volumes of data must move between compute and storage systems.

The 200G bandwidth can provide substantial aggregate throughput for supported storage networking architectures, although actual application performance depends on the network equipment, protocols, cabling and endpoint capabilities.

High-Performance Computing

High-performance computing environments can benefit from high-bandwidth, low-distance optical interconnects between compute nodes, switches and aggregation infrastructure.

The 200G SR4 module is suited to short-reach multimode fiber environments where high aggregate bandwidth is required.

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 Cisco's Transceiver Modules Compatibility Matrix before deployment. :contentReference[oaicite:9]{index=9}

Because the exact designation QSFP-DD-200G-SR4 was not found in the current Cisco 200G portfolio documentation, customers should verify the exact Cisco PID printed on the module before ordering or installation.

Optical Link Planning

For reliable 200G SR4 operation, the transceiver must be paired with compatible multimode fiber, connector type, polarity and optical components.

• Use compatible OM3, OM4 or OM5 MMF
• Use MPO-12 compatible optical cabling
• Verify connector polish and polarity
• Stay within the specified link distance
• Verify transceiver compatibility on both endpoints
• Confirm supported breakout configuration where applicable

200G SR4 vs 200G FR4

Cisco's current 200G portfolio lists QSFP-200G-SR4-S for 100m OM4 MMF and QSFP-200G-FR4-S for 2km duplex SMF, illustrating the different reach and fiber requirements of SR4 and FR4 implementations. :contentReference[oaicite:10]{index=10}
