Generic Compatible 200GBASE-SR8 QSFP-DD 8x25G NRZ 850nm 100m MMF DOM MPO-16/APC Optical Transceiver Module

The Generic Compatible 200GBASE-SR8 QSFP-DD optical transceiver is designed for high-density, short-reach 200G Ethernet connectivity in modern data center networks. Operating at an aggregate data rate of 200Gb/s, it features an eight-channel parallel optical architecture, with each lane supporting 25.78Gb/s NRZ signaling. This architecture provides efficient 200G connectivity for high-performance servers, switches, and data center interconnects.

Operating at a nominal wavelength of 850nm, the module supports transmission distances of up to 70m over OM3 multimode fiber and 100m over OM4 multimode fiber. It uses an MPO-16/APC optical connector to accommodate the parallel optical channels in a compact QSFP-DD form factor. Digital Diagnostic Monitoring (DDM) provides access to key operating parameters, helping network operators monitor module status and maintain link reliability.

On the host side, the transceiver uses a 200GAUI-8 electrical interface, with eight electrical lanes supporting the 200G aggregate data rate. It is designed for integration into compatible QSFP-DD networking equipment and supports applications requiring high-density 200G optical connectivity. The module is designed in accordance with the QSFP-DD MSA and applicable CMIS and IEEE specifications.

This product is based on the QDD-400G-SR8 hardware platform and supports downshift operation in compatible 200G Ethernet environments. This provides additional flexibility for network deployments that require 200G connectivity using a 400G hardware platform. Actual operation depends on the module’s firmware, configuration, and host-device support.

For network migration and port optimization, the module can support 2x100G breakout applications when the host platform and optical lane mapping are compatible. With an appropriate MPO-16-to-dual-MPO-12 breakout cable, it can connect to two 100GBASE-SR4 optical interfaces, subject to correct fiber polarity and connector specifications.

Combining eight-lane NRZ signaling, short-reach multimode optics, and the QSFP-DD form factor, this 200GBASE-SR8 transceiver provides a flexible connectivity option for data center switching, server aggregation, and high-performance computing networks.

Highlights

Flexible 200G to 2x100G Network Connectivity

The QDD-200G-SR8 supports network architectures that require both 200G aggregate connectivity and flexible 100G link deployment. In compatible breakout configurations, one 200G port can provide two independent 100G connections, helping network operators connect multiple 100G devices while improving switch port utilization. This capability is particularly useful when upgrading server access networks or integrating existing 100G infrastructure into a 200G environment.

Ideal for High-Density Data Center Switching

Designed for QSFP-DD platforms, this transceiver is suitable for high-density switch-to-server and switch-to-switch connections. It helps data center operators expand bandwidth capacity while making efficient use of available front-panel ports, supporting scalable network designs for enterprise data centers, cloud infrastructure, and high-performance computing environments.

Practical Multimode Fiber Deployment

The 850nm SR8 optical architecture is well suited to short-reach connections within equipment racks and across nearby data center rows. OM3 and OM4 multimode fiber provide practical cabling options for different link-distance requirements, helping reduce the complexity of short-distance optical deployment.

A Flexible Option for 100G Infrastructure Migration

The 2x100G breakout capability provides a migration path for environments where 100G SR4 interfaces remain in service. With compatible host ports and correctly specified MPO breakout cabling, the module can support connections to two 100G optical links, allowing network operators to adapt port configurations to changing bandwidth requirements.

Hardware Platform Flexibility

Based on the QDD-400G-SR8 hardware platform, the product supports downshift operation in compatible 200G environments. This approach provides an additional deployment option for networks using different port speeds. Host compatibility, firmware support, and operating-mode configuration should be verified before installation to ensure the intended link operation.

Simplified Network Monitoring and Troubleshooting

DDM support helps engineers monitor key optical and module operating parameters during deployment and daily operation. This visibility can assist with link diagnostics, preventive maintenance, and troubleshooting in high-density data center environments.

Suitable for Evolving Data Center Architectures

The QDD-200G-SR8 is suitable for data center switching, server aggregation, HPC clusters, and network environments transitioning from 100G to 200G connectivity. Its parallel optical design and breakout flexibility help support evolving bandwidth requirements without requiring every network connection to operate at the same speed.

A: The QDD-200G-SR8 supports link distances of up to 70m over OM3 multimode fiber and 100m over OM4 multimode fiber, using an 850nm optical wavelength under specified operating conditions. Actual link performance depends on fiber quality, connector cleanliness, cable polarity, and the optical specifications of the connected equipment.

Q: What is the operating temperature range of the QDD-200G-SR8?

A: The typical commercial operating temperature range is 0°C to 70°C. Within this range, the module is designed to maintain stable operation under its specified electrical and optical conditions. For deployment in environments with special temperature requirements, please confirm the exact operating-temperature specification of the selected module.

Q: What is the difference between the QDD-200G-SR8 and the Q56-200G-SR4?

A: The main differences are their form factors, lane configurations, and modulation formats. The QDD-200G-SR8 uses a QSFP-DD form factor with eight 25G NRZ optical lanes, while the Q56-200G-SR4 uses a QSFP56 form factor with four 50G PAM4 optical lanes. Both provide an aggregate 200Gb/s data rate, but they use different optical architectures and host interfaces. Make sure the selected module matches the port type and optical connectivity requirements of your equipment.

Q: What are the typical applications of the QDD-200G-SR8?

A: The QDD-200G-SR8 is designed for short-reach 200G Ethernet links in data centers, high-performance computing environments, and high-density switch interconnections. It can also support 2x100G breakout applications connecting compatible 100GBASE-SR4 equipment through an appropriate MPO-16-to-dual-MPO-12 breakout cable. The host switch must support the required port breakout configuration, and the optical lane mapping, connector polarity, and cable specifications must match the module.

Q: Can the QDD-200G-SR8 connect to two 100GBASE-SR4 optical transceivers?

A: Yes, in a supported 2x100G breakout configuration. The QSFP-DD module’s optical lanes can be connected to two compatible 100GBASE-SR4 interfaces using a suitable MPO-16-to-dual-MPO-12 multimode breakout cable. Successful operation requires compatible optical lane mapping, fiber polarity, connector configuration, and host-side breakout settings. Verify the cable and equipment specifications before deployment.

Q: Why is the delivered module labeled QDD-400G-SR8 when I ordered a 200G SR8 transceiver?

A: This product is based on the QDD-400G-SR8 hardware platform and is configured to support operation in a 200G Ethernet mode. As a result, the physical module may carry a QDD-400G-SR8 model label even when supplied for a 200G application. Before installation, confirm that the module firmware, operating mode, and host port configuration support 200G operation. The supported performance and interoperability should be evaluated against the specified 200G operating mode.
