Frequently Asked Questions

What is the primary application for the Cisco QDD-400G-DR4-S transceiver? +

The QDD-400G-DR4-S is designed for high-density 400G Ethernet connectivity in data center environments. It utilizes single-mode fiber to support reach distances of up to 500 meters, making it ideal for interconnecting leaf-and-spine switches or aggregating high-bandwidth traffic within large-scale enterprise network infrastructures.

Does the QDD-400G-DR4-S support breakout configurations? +

Yes, this module supports 4x100G breakout applications. By utilizing the MPO-12 connector interface, the transceiver allows network administrators to break out a single 400G port into four individual 100G parallel links, providing significant flexibility for connecting to 100G-DR-based switch ports or high-density server clusters.

What type of optical interface does this module utilize? +

The QDD-400G-DR4-S features an MPO-12 optical interface. This standard interface is specifically engineered for parallel single-mode fiber applications, ensuring precise alignment and reliable signal integrity when transmitting data across short-reach fiber runs within the data center.

Is the Cisco QDD-400G-DR4-S compatible with standard QSFP-DD switch ports? +

This module is fully compliant with the QSFP-DD (Quad Small Form-factor Pluggable Double Density) multi-source agreement. It is built to operate seamlessly in any networking hardware that supports standard QSFP-DD 400G slots, ensuring integration into existing Cisco switching and routing architectures.

What are the power consumption characteristics of this 400G module? +

As a high-performance 400G transceiver, the QDD-400G-DR4-S is optimized for power efficiency within thermal constraints typical of high-density chassis. It operates within the standard power envelope defined by the QSFP-DD MSA for DR4 modules, helping maintain optimal thermal management in high-port-density switch deployments.

What fiber cabling is required to achieve the full performance of the QDD-400G-DR4-S? +

To achieve peak performance and meet link budget requirements, you must use single-mode fiber (SMF) with an MPO-12 connector. This setup ensures the module operates at its rated 400G throughput over the specified 500-meter reach, maintaining the high signal-to-noise ratio necessary for error-free data transmission.

How does the DR4 variant differ from other 400G transceiver standards? +

The DR4 standard is specifically optimized for parallel single-mode fiber. Unlike FR4 variants that utilize WDM technology to multiplex signals onto a single duplex fiber, the DR4 transmits four parallel lanes over MPO cabling, providing a cost-effective and low-latency solution for high-density, short-reach intra-data center connections.

Can the QDD-400G-DR4-S handle standard industrial temperature ranges? +

The module is designed to operate reliably within the standard commercial temperature ranges typical of climate-controlled enterprise data centers. It is essential to ensure that your switch airflow and cooling systems are properly configured to keep the module within its specified operating thermal envelope for maximum reliability.

How can I obtain a bulk quote for multiple QDD-400G-DR4-S units? +
