Product overview

100G QSFP28 DR1 is designed for 500m links using Duplex LC. Selection must confirm the host form factor, electrical interface, PMD, FEC, fiber mapping, power and thermal limits, software version and the remote endpoint; the model name alone does not establish interoperability.

  • QSFP28 DR1 form factor for the defined host-port direction.

  • Duplex LC interface for 500m links.

  • Parallel single-mode optical transmission; confirm the exact fiber or cable assembly before ordering.

  • Validate host coding, FEC, diagnostics, power, thermal behavior and long-duration stability.

Selection and deployment notes

  • Before ordering 100G QSFP28 DR1, confirm the exact host, software, port mode, reach, fiber or cable, connector, FEC, temperature, quantity, compatibility coding and delivery version.

Selection FAQ

100G QSFP28 DR1 selection questions

What fiber does 100G QSFP28 DR1 require?

Parallel single-mode fiber on Duplex LC, listed for 500m. Confirm the trunk type and lane order in the installed plant before ordering.

How does 100G QSFP28 DR1 differ from a duplex single-mode module at the same rate?

100G QSFP28 DR1 spreads its lanes across parallel fiber on Duplex LC, so it needs a parallel trunk and suits breakout planning. A duplex option carries the same rate over one fiber pair on LC, which fits structured cabling that was never built for parallel trunks. The two are not interchangeable even though both are single-mode.

What do I need to specify to request a quote for 100G QSFP28 DR1?

Give the host vendor, model and software version at both ends, the QSFP28 port or lane mode, the operating temperature range, the quantity per site and the target delivery date. For 100G QSFP28 DR1 also state whether the link stays at full rate or breaks out and which Duplex LC trunk is already installed. Compatibility is confirmed per platform, so the host details matter as much as the optical specification.
