The nominal optical wavelength is 850nm, making the module suitable for multimode fiber-based short-reach data center links. :contentReference[oaicite:3]{index=3}

850nm Multimode Fiber

The module operates at a nominal wavelength of 850nm over multimode fiber. Cisco specifies 50-micron MMF with modal bandwidth requirements of 2000 MHz·km for OM3 and 4700 MHz·km for OM4 and OM5. :contentReference[oaicite:4]{index=4}

OM4 and OM5 fiber are particularly suitable when taking advantage of the module's full 100-meter reach.

100-Meter Reach over OM4

Cisco specifies a maximum distance of 100 meters over OM4 MMF. The module can also reach 70 meters over OM3 and 100 meters over OM5. :contentReference[oaicite:5]{index=5}

MPO-12 UPC Connector

The Cisco QSFP-200G-SR4-S uses an MPO-12 UPC optical connector. Cisco specifically states that connections use patch cords with PC or Ultra-Physical Contact (UPC) connectors. :contentReference[oaicite:6]{index=6}

When deploying the module, ensure that the fiber polarity, MPO connector type and patch-cord configuration are compatible with the connected optical equipment.

200G QSFP56 Form Factor

The QSFP-200G-SR4-S uses the QSFP56 form factor. QSFP56 provides a compact, high-density pluggable architecture suitable for modern 200GbE switching platforms.

Cisco states that its QSFP modules are supported across Cisco switches, routers and NICs as well as selected third-party host platforms and NICs, subject to the applicable compatibility matrix. :contentReference[oaicite:7]{index=7}

2×100G and 4×50G Breakout

The QSFP-200G-SR4-S supports flexible breakout configurations. Cisco specifies that the module can be used as a 2×100GBASE-SR2 breakout or as 4×50GBASE-SR connections. :contentReference[oaicite:8]{index=8}

This allows a single 200G QSFP56 port to provide connectivity to multiple lower-speed interfaces when supported by the host platform and network configuration.

200GAUI-4 Electrical Interface

The module uses a 200GAUI-4 / CEI-56G-VSR-PAM4 electrical interface. Cisco identifies the module as compliant with the relevant 200GAUI-4 and CEI-56G-VSR-PAM4 standards. :contentReference[oaicite:9]{index=9}

The PAM4-based architecture enables high data rates while maintaining a compact QSFP56 form factor suitable for high-density networking.
