FAQs

Q: What is the maximum transmission distance for the QSFP-200G-FR4?
A: The QSFP-200G-FR4 supports transmission distances up to 2 kilometers over single-mode fiber (SMF) with duplex LC connectors, making it suitable for data center interconnects and campus core networks.

Q: Is this transceiver compatible with 100G infrastructure?
A: Yes, the QSFP-200G-FR4 supports dual-rate operation at both 200GBASE-FR4 and 100GBASE-CWDM4, allowing backward compatibility with 100G CWDM4 optics using the same fiber type and LC connectors, enabling seamless network upgrades.

Q: What fiber type is required for this module?
A: The transceiver requires single-mode fiber (SMF) with duplex LC/UPC or LC/PC connectors. It operates over four CWDM wavelengths (1271nm, 1291nm, 1311nm, 1331nm) for optimal performance.

Q: Does the QSFP-200G-FR4 require Forward Error Correction?
A: Yes, Forward Error Correction (FEC) is required by the host system for the QSFP-200G-FR4 to achieve the specified 2km reach and ensure optimal link performance and reliability.

Q: Can this transceiver be used in QSFP-DD ports?
A: Yes, QSFP56 modules like the QSFP-200G-FR4 can be inserted into QSFP-DD ports when configured for 200G operation, providing backward compatibility with QSFP-DD infrastructure.
