Questions & Answers

QSFP-100G-LR: Frequently Asked Questions

Q: What is the transmission distance of the QSFP-100G-LR?

A: The QSFP-100G-LR is designed for 100G transmission over single-mode fiber (SMF), with a typical reach of up to 10km when used with compatible duplex LC fiber cables. Actual reach depends on the module specifications, fiber quality, and link conditions.

Q: What is the maximum power consumption of the QSFP-100G-LR?

A: The QSFP-100G-LR has a maximum power consumption of 4.5W, making it suitable for 100G network deployments where power efficiency is an important consideration.

Q: What is the difference between the QSFP-100G-LR and QSFP-100G-LR4?

A: The key difference is the optical transmission architecture. A single-wavelength 100G LR module transmits the 100G optical signal over one wavelength, typically using PAM4 modulation. A conventional QSFP28 100G-LR4 module uses four optical wavelengths, each carrying approximately 25Gb/s using NRZ modulation. Both solutions can support long-reach 100G links over single-mode fiber, but their optical designs, interoperability requirements, and specifications differ. Always verify the exact module datasheet before selecting a replacement.

Q: How does single-wavelength 100G technology relate to 400G optical networking?

A: Single-wavelength 100G technology carries 100Gb/s over one optical wavelength. In a 400G system designed around four 100G optical lanes, this approach can help simplify the optical architecture compared with designs using eight 50G lanes. However, a QSFP-100G-LR is a 100G transceiver and does not automatically support 400G operation. Compatibility depends on the host interface, optical lane architecture, and system design.

Q: What are the advantages of single-wavelength 100G optical modules?

A: Single-wavelength 100G optical modules carry 100Gb/s over one optical wavelength, potentially reducing the number of optical wavelengths and simplifying the optical design compared with four-wavelength 25Gb/s solutions. Depending on the application, this architecture may help reduce component complexity and system costs. Actual power consumption, transmission distance, and interoperability depend on the module specifications and network equipment.
