200Gbps High-Speed Connectivity
The QDD-200G-PSM8-O provides a 200Gbps optical network interface for environments where high bandwidth and port density are important.
Cisco's 200G QSFP portfolio is designed for applications including AI/ML data centers, server NIC connectivity, data center switches, enterprise core and distribution networks, high-performance computing and service-provider environments. :contentReference[oaicite:2]{index=2}
QSFP-DD Form Factor
QSFP-DD stands for Quad Small Form-Factor Pluggable Double Density. The form factor provides a high-density pluggable interface suitable for modern high-speed networking equipment.
The QSFP-DD architecture provides eight electrical lanes and supports high-speed optical modules in a compact form factor. Cisco's QSFP portfolio supports high-density 200G networking and provides compatibility with relevant QSFP-based networking platforms. :contentReference[oaicite:3]{index=3}
200G PSM8 Technology
The QDD-200G-PSM8-O uses 200G PSM8 parallel single-mode technology. PSM8 uses multiple parallel optical lanes over single-mode fiber rather than multiplexing multiple wavelengths onto a single fiber pair.
This architecture is suitable for high-bandwidth data center links where single-mode fiber infrastructure and longer reach are required.
10km Transmission Distance
The QDD-200G-PSM8-O is specified for transmission distances of up to 10km over single-mode fiber. This makes it suitable for longer data center interconnects, campus-scale links and other applications where a 200G connection must extend beyond typical short-reach data center distances.
Actual achievable distance depends on fiber quality, connector loss, splice loss, optical budget, installation conditions and the characteristics of the connected equipment.
1310nm Optical Wavelength
The transceiver operates at a nominal 1310nm wavelength. This optical window is widely used for single-mode fiber communications and is appropriate for medium- and long-reach Ethernet applications.
Single-Mode Fiber Support
The QDD-200G-PSM8-O is designed for single-mode fiber (SMF). Single-mode fiber provides the optical characteristics required for long-distance, high-bandwidth transmission.
Use the appropriate single-mode MPO-16 fiber infrastructure and verify connector polarity and lane mapping before deployment.
MPO-16 Connector
The module uses an MPO-16 optical connector. MPO-16 provides a multi-fiber interface suitable for parallel optical transmission.
Correct MPO polarity, fiber type, connector gender and lane assignment are important when installing PSM8 modules. Always verify the complete fiber assembly before connecting the transceiver.
DFB Laser Technology
The QDD-200G-PSM8-O specification identifies a DFB laser transmitter. Distributed Feedback lasers provide a controlled optical source suitable for high-speed fiber communications.
PIN Receiver
The module uses a PIN photodetector receiver. The receiver converts incoming optical signals into electrical signals for processing by the host networking equipment.
NRZ Modulation
The documented QDD-200G-PSM8-O configuration uses NRZ modulation. The optical interface uses multiple parallel lanes to achieve the aggregate 200Gbps data rate.
Digital Diagnostics Monitoring
The QDD-200G-PSM8-O supports DDM, allowing supported host equipment to monitor operational parameters of the optical module.
Digital diagnostics can provide useful information for network administrators when troubleshooting optical links and monitoring transceiver operating conditions.
Optical Performance
The documented QDD-200G-PSM8-O configuration specifies a minimum transmit power of approximately -5dBm per lane, maximum transmit power of approximately +2.2dBm, and receiver sensitivity of approximately -9.5dBm. The specified optical power budget is approximately 4.5dB. ([prooptix.se](https://portal.prooptix.se/en/fiber-optical-transceivers/4529-qdd-200g-psm8-o-cisco-qsfp-dd))
Actual link performance depends on fiber attenuation, connector loss, splice loss, patch-panel configuration and environmental conditions.
Power Consumption
The QDD-200G-PSM8-O is documented with power consumption of approximately 6.5W. ([prooptix.se](https://portal.prooptix.se/en/fiber-optical-transceivers/4529-qdd-200g-psm8-o-cisco-qsfp-dd))
Actual module power consumption may vary according to host platform, operating conditions, firmware and optical activity.
Operating Temperature
The documented operating temperature range is 0°C to 70°C, making the module appropriate for standard data center and controlled enterprise networking environments. ([prooptix.se](https://portal.prooptix.se/en/fiber-optical-transceivers/4529-qdd-200g-psm8-o-cisco-qsfp-dd))
Data Center and AI/ML Networking
200G optical connectivity is increasingly important in high-density data center architectures, AI/ML infrastructure and high-performance computing environments.
Cisco identifies its 200G QSFP portfolio for AI/ML data centers, server NICs, data center switches, enterprise core and distribution layers, HPC and service-provider applications. :contentReference[oaicite:4]{index=4}
High-Performance Computing
HPC environments require high-bandwidth and low-congestion interconnects between compute, storage and networking resources. A 200G optical interface can provide substantially higher aggregate bandwidth than 100G links while maintaining a compact pluggable form factor.
Data Center Interconnect
With its 10km reach and single-mode fiber design, the QDD-200G-PSM8-O can be considered for longer-reach data center connectivity where supported by the host platform and optical design.
Before deployment, perform an optical link-budget calculation that accounts for the complete fiber path, including patch panels, connectors and splices.
Hot-Pluggable Optical Networking
Cisco's 200G QSFP portfolio identifies QSFP modules as hot-swappable input/output devices that plug into supported QSFP ports. :contentReference[oaicite:5]{index=5}
Hot-swapping should only be performed on equipment and ports where the host platform explicitly supports the operation.
Compatibility
The QDD-200G-PSM8-O is a Cisco-compatible QSFP-DD transceiver. The exact host-platform compatibility should be verified using the Cisco transceiver compatibility matrix and the specific switch, router or NIC documentation before purchase.
Cisco states that its QSFP modules are supported across Cisco switches, routers and NICs as well as certain third-party host platforms and NICs, with detailed compatibility provided through the Cisco Transceiver Modules Compatibility Matrix. :contentReference[oaicite:6]{index=6}
