Finisar compatible FTCD4313E1PCL Description

The EDGE 400G-QSFP-DD-2.1 is a direct replacement for the Finisar FTCD4313E1PCL 400GBASE-FR4 QSFP-DD module. Finisar (now II-VI Coherent) is an OEM transceiver manufacturer whose modules ship as factory-installed optics by equipment vendors. Same duplex LC connector, same 2km single-mode reach.

The module transmits on four CWDM wavelengths (1271, 1291, 1311, 1331nm) using PAM4 modulation at 53.125 GBaud per lane for a 400 Gb/s aggregate data rate. An internal DSP performs gearbox adaptation between the electrical host interface and the four optical lanes. Rated for a 4dB maximum optical link budget, supporting 2km over OS2 single-mode fiber. Operating temperature 0 to 70°C.

Finisar lists two revisions in this family: FTCD4313E1PCL and FTCD4313E2PCL. Both share the same 400GBASE-FR4 optical specifications. The EDGE replacement is compatible with both. If your system identifies FTCD4313E1PCL via the EEPROM vendor field, this is the correct module.

The module conforms to IEEE 802.3cu for the 400GBASE-FR4 optical interface. Diagnostic monitoring via CMIS provides real-time per-channel transmit and receive power, temperature, voltage, and bias current through your platform management interface.

Frequently Asked Questions

What is the difference between FTCD4313E1PCL and FTCD4313E2PCL?

Both are Finisar (now II-VI Coherent) 400GBASE-FR4 QSFP-DD modules with the same optical specifications and 2km reach. The E1 and E2 suffixes denote different hardware revisions. The EDGE 400G-QSFP-DD-2.1 replacement is compatible with both variants.

Who manufactures the FTCD4313E1PCL?

The FTCD4313E1PCL is manufactured by Finisar, now part of II-VI Coherent. Finisar is an OEM transceiver supplier whose modules ship as factory-installed optics under other vendors' branding. If your switch reports FTCD4313E1PCL in the EEPROM vendor field, the EDGE 400G-QSFP-DD-2.1 is a direct replacement.
