QSFP-100G-SRBD: Frequently Asked Questions

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

A: The QSFP-100G-SRBD can support transmission distances of up to 70m over OM3 multimode fiber and 100m over OM4 multimode fiber, depending on the module specifications and link conditions. If you plan to use OM5 fiber, verify the supported reach in the manufacturer’s datasheet before deployment.

Q: What is the difference between 100G SRBD, 100G SWDM4, and 100G SR4?

A: The main differences are their optical lane architectures and fiber interfaces. A typical 100G SR4 module uses parallel optical lanes and an MPO/MTP interface, while 100G SRBD and SWDM4 modules typically use duplex LC multimode fiber. SRBD uses two bidirectional optical channels, whereas SWDM4 uses four wavelengths with wavelength multiplexing. Both LC-based solutions can reduce the number of fibers required in the cabling plant compared with SR4, but reach and interoperability depend on the exact module specifications.

Q: What type of fiber connection does the QSFP-100G-SRBD use?

A: The QSFP-100G-SRBD typically uses a duplex LC connector with multimode fiber (MMF). Select compatible fiber cabling based on the module’s specified reach, supported fiber grade, and optical requirements.

Q: What are the key features of the QSFP-100G-SRBD?

A: The QSFP-100G-SRBD is a 100G QSFP28 bidirectional multimode optical transceiver designed for short-reach data center connectivity. It uses duplex LC multimode fiber and bidirectional optical transmission to send and receive data over two fibers, with an aggregate data rate of up to 100Gb/s. Its maximum power consumption is 3.5W, making it suitable for high-density network environments where power efficiency is important. Confirm the exact lane rate, wavelengths, and supported fiber distances in the product datasheet.

Q: Can the QSFP-100G-SRBD interoperate with a QSFP-100G-SWDM4?

A: Direct interoperability should not be assumed. SRBD and SWDM4 use different optical channel and wavelength architectures. Even if both modules use duplex LC multimode fiber, their transmit and receive wavelengths, optical specifications, and encoding requirements may differ. Before connecting them, confirm that the specific module datasheets explicitly support interoperability at both ends of the link.
