Frequently Asked Questions

What is the primary application for the Cisco QSFP-100G-DR-S transceiver? +

The Cisco QSFP-100G-DR-S is designed for high-speed 100G Ethernet connectivity over single-mode fiber. It is primarily used in data center leaf-spine architectures for short-to-medium reach links, typically supporting distances up to 500 meters. It serves as an efficient solution for interconnecting high-density switches and routers where low power consumption and reliable 100G performance are required.

Does the QSFP-100G-DR-S module support interoperability with other 100G standards? +

Yes, this module is built to IEEE 802.3cu standards. It is fully interoperable with other 100G-DR interfaces that adhere to the same specifications. When deploying, ensure that both ends of the fiber link are configured for 100G-DR operation to maintain signal integrity and proper link synchronization across your existing optical network infrastructure.

What type of optical interface does this Cisco transceiver utilize? +

This transceiver utilizes a duplex LC connector interface. Unlike older 100G modules that may require MPO-12 connectors for parallel fiber, the DR-S utilizes a single-mode fiber pair. This simplifies your cable management and reduces the cost of fiber infrastructure, making it an excellent choice for modern data center environments requiring streamlined physical cabling.

Is the Cisco QSFP-100G-DR-S compatible with standard QSFP28 switch ports? +

Absolutely. The module follows the industry-standard QSFP28 form factor, ensuring physical and electrical compatibility with most Cisco switch and router platforms that feature QSFP28 ports. Always verify that your specific switch hardware and software version support the 100G-DR-S protocol before final installation to ensure optimal feature set recognition and link stability.

How does the power consumption of the QSFP-100G-DR-S compare to earlier 100G modules? +

This module is engineered for high energy efficiency, consuming significantly less power compared to legacy 100G optical transceivers. By reducing heat dissipation, it allows for higher port density in switches without exceeding thermal constraints. This efficiency is critical for maintaining a stable operating environment in high-density racks where thermal management is a primary operational concern.

Can I use the QSFP-100G-DR-S for breakout applications to 10G or 25G? +

The QSFP-100G-DR-S is strictly designed for 100G to 100G point-to-point single-mode connections. It does not natively support breakout configurations into 10G or 25G channels. If your network design requires breakout functionality, please review our inventory for specific QSFP28 modules that support channelized operations or consider using a different transceiver type optimized for multi-rate deployment.

What is the operational wavelength of the Cisco QSFP-100G-DR-S? +

The module operates at a wavelength of 1310 nm. This wavelength is ideal for single-mode fiber applications, providing excellent transmission characteristics over the specified 500-meter reach. Using 1310 nm optics ensures that you are utilizing standard industry practices for high-speed signal propagation, minimizing dispersion and attenuation in your fiber plant for a robust data link.

Are there specific maintenance or cleaning requirements for the LC interface? +

Maintaining a clean optical connection is vital for 100G performance. Because the DR-S utilizes sensitive single-mode LC connections, you should always inspect the fiber end-faces with a fiber microscope before insertion. Use standard fiber cleaning tools to ensure that dust or oil contaminants do not degrade the optical budget, which could otherwise lead to link errors or intermittent connectivity.
