Product overview

200G QSFP56 FR4 is designed for 2km 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.

  • QSFP56 FR4 form factor for the defined host-port direction.

  • Duplex LC interface for 2km links.

  • WDM 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 200G QSFP56 FR4, confirm the exact host, software, port mode, reach, fiber or cable, connector, FEC, temperature, quantity, compatibility coding and delivery version.

Selection FAQ

200G QSFP56 FR4 selection questions

What fiber and connector does 200G QSFP56 FR4 need?

Duplex single-mode fiber on Duplex LC, listed for 2km. It reuses ordinary structured single-mode cabling, which is usually why it is chosen over a parallel option at the same rate.

How does 200G QSFP56 FR4 differ from a parallel single-mode module at the same rate?

200G QSFP56 FR4 carries the full rate over a single fiber pair, so it drops into existing duplex cabling. A parallel variant needs an MPO trunk and is chosen when the plan is to break the link out to lower-rate ports. Reach targets also differ, so compare against the measured link budget.

What do I need to specify to request a quote for 200G QSFP56 FR4?

Give the host vendor, model and software version at both ends, the QSFP56 port or lane mode, the operating temperature range, the quantity per site and the target delivery date. For 200G QSFP56 FR4 also state the measured link distance and the number of patch points in the path. Compatibility is confirmed per platform, so the host details matter as much as the optical specification.
