FN-TRAN-QSFPDD-FR4 is Fortinet's 400GBASE-FR4 QSFP-DD module for 2 km single-mode links. It uses duplex LC and four wavelengths (1271/1291/1311/1331 nm) and operates from 0°C to 70°C.
FR4 is the 2 km duplex-LC option. LR4 extends to 10 km, while DR4+ uses an MPO-12 parallel-fiber interface. Confirm the connector and standard at both ends before ordering.
Record distance, connector/splice count and measured loss, including patch leads. Clean LC interfaces and confirm the far-end module is FR4-compatible.
Verify module identification, lane alarms, power diagnostics, FEC, errors and sustained traffic. Check host firmware and QSFP-DD support; form factor alone does not prove compatibility.
