Finisar compatible FTCD4313E1PCL Description
FTCD4313E1PCL is the first-generation (E1) 400GBASE-FR4 QSFP-DD from Finisar's FTCD4313 family -- now under Coherent after the Finisar > II-VI > Coherent acquisitions. EdgeOptic's compatible matches this module exactly. Don't confuse it with the second-gen FTCD4313E2PCL -- different internal design, same optical output.
Two generations exist in the FTCD4313 family. E1PCL is first-gen, the FTCD4313E2PCL is second-gen. Same 400GBASE-FR4 optical standard -- same CWDM wavelengths, same 2 km reach, same LC duplex connector. The E2 brought improved power efficiency and updated internal electronics, but optical performance is identical. Both PCL variants are commercial temp (0 to 70 C). When replacing an installed E1PCL, the E1 compatible is the exact match. No reason to move to E2 unless platform firmware specifically requires the newer generation.
Four CWDM wavelengths (1271/1291/1311/1331 nm), EML lasers, PIN receiver. PAM4 at 106.25 Gbps per lane, 400G aggregate throughput. LC duplex over OS2 single-mode fiber, 2 km maximum reach. Budget: 4.0 dB (TX -3.3 to +3.5 dBm, RX -7.3 dBm). Under 11W power consumption. KP4 FEC (RS(544,514)) required on the host side. DOM supported via CMIS 4.0. Full parameters on the 400GBASE-FR4 product page.
Finisar was acquired by II-VI in 2019; II-VI became Coherent in 2023. As a first-gen product, the E1PCL may no longer be in active OEM production -- the E2PCL has likely superseded it in Coherent's product catalog. EdgeOptic's compatible is in stock and ships immediately regardless of Coherent's production decisions.
The FTCD4313E1PCL was an OEM component used across equipment from multiple switch vendors. EdgeOptic codes the compatible with vendor-specific EEPROM -- Cisco, Arista, Juniper, Huawei, and others. On Cisco platforms, Cisco-recognized EEPROM is programmed so Nexus and Catalyst accept it without CLI workarounds. Every module ships pre-coded for the specified vendor. Specify the switch platform when ordering.
IEEE 802.3cu-2021, 100G Lambda MSA 400G-FR4, QSFP-DD MSA, CMIS 4.0 compliant. DOM covers TX/RX optical power per lane, temperature, bias current, supply voltage. Electrical interface: 400GAUI-8 or 400GAUI-4 (depends on module generation) using CEI-56G-VSR-PAM4 signaling. 0 to 70 C commercial operating temperature. RoHS compliant.

Frequently Asked Questions
What is the difference between the Finisar FTCD4313E1PCL and FTCD4313E2PCL?
E1 = first gen, E2 = second gen of the FTCD4313 FR4 family. Identical optical specs -- CWDM4, 2 km, LC duplex. E2 has improved internal electronics and likely lower power draw. Both PCL variants are commercial temp (0 to 70 C).
Will a compatible FTCD4313E1PCL work in any 400G FR4-capable QSFP-DD port?
Yes, as long as the EEPROM is coded for the target switch vendor and the host enables KP4 FEC (RS(544,514)). EdgeOptic codes for the specific target platform.
