Finisar compatible FTCD4313E2PCL Description
FTCD4313E2PCL is the second-generation (E2) 400GBASE-FR4 QSFP-DD from Finisar's FTCD4313 family -- now under Coherent after the Finisar > II-VI > Coherent acquisition chain. EdgeOptic's compatible matches this OEM module's optical and electrical interface for a direct drop-in replacement.
Finisar split the FTCD4313 into two generations and two temperature grades. E2PCL is second-gen, commercial temp (0 to 70 C). PCL = commercial, PXL = extended temperature (-5 to 85 C). The first-gen E1PCL uses the same 400G FR4 optical standard but may differ in power draw and internal DSP design. Don't swap part numbers between generations -- the E2 variant matters for inventory tracking even though optical output is identical. When replacing an installed FTCD4313E2PCL, order the E2 specifically.
Four CWDM wavelengths -- 1271, 1291, 1311, 1331 nm -- EML lasers, PIN receivers. PAM4 at 106.25 Gbps per lane, 400G aggregate. LC duplex into OS2 single-mode, 2 km reach, 4.0 dB link budget. TX -3.3 to +3.5 dBm, RX sensitivity -7.3 dBm. Under 11W. KP4 FEC (RS(544,514)) required on the host side. DOM through I2C per CMIS 4.0 provides per-lane visibility into optical power levels. More detail on the 400GBASE-FR4 product page.
Finisar was acquired by II-VI in 2019; II-VI rebranded to Coherent in 2023. OEM FTCD4313E2PCL modules can be difficult to source -- lead times through Coherent distribution vary and pricing tends to run higher than under the original Finisar name. EdgeOptic's compatible is coded with the correct EEPROM for the target platform, so Cisco, Arista, Juniper, and other vendors accept it without extra configuration.
Because the FTCD4313E2PCL started as an OEM part used across many switch vendors, EdgeOptic offers vendor-specific EEPROM coding. Specify the target platform when ordering -- Cisco, Arista, Juniper, Huawei, Nokia. On Cisco gear, EdgeOptic programs Cisco-recognized EEPROM so Nexus and Catalyst accept it without CLI workarounds. Every module ships pre-coded for the specified vendor.
Compliant with IEEE 802.3cu-2021, 100G Lambda MSA 400G-FR4, QSFP-DD MSA, CMIS 4.0. Class 1 Laser Product, RoHS-6 per Directive 2011/65/EU. Electrical side uses 400GAUI-8 with CEI-56G-VSR-PAM4 signaling between the module DSP and host ASIC. Operating temperature range is 0 to 70 C (commercial grade).

Frequently Asked Questions
What is the difference between Finisar FTCD4313E2PCL and FTCD4313E2PXL?
PCL = commercial temperature, 0 to 70 C. PXL = extended temperature, -5 to 85 C. Optically identical -- the only difference is the case temperature rating.
Will a compatible FTCD4313E2PCL work in a switch that originally shipped with the Finisar OEM module?
Yes. EdgeOptic programs the EEPROM for the specific switch vendor -- Cisco, Arista, Juniper, or others. Specify the platform when ordering.
