FTCD4315E1PCL: frequently asked questions
What is the Finisar FTCD4315E1PCL?
The FTCD4315E1PCL is a Finisar OSFP transceiver for 400GBASE-FR4 at 400 Gb/s. Finisar is now part of Coherent Corp. (formerly II-VI), and the part number is unchanged. It is used for 400G data-centre spine, AI/ML clusters and 400ZR / ZR+ coherent DCI.
What is the maximum distance of the FTCD4315E1PCL?
The FTCD4315E1PCL is specified for up to 2 km over Duplex SMF, LC. Long-reach optics may need an attenuator on short links; we can advise based on your link loss.
What is the optical power budget of the FTCD4315E1PCL?
Per the Finisar family datasheet, the FTCD4315E1PCL transmits −3.2 to 4.4 dBm per lane and has a receiver sensitivity of −4.6 dBm OMAouter (SECQ < 1.4 dB). Maximum receiver input is 4.4 dBm avg receive power; 5.4 dBm damage threshold.
Does the FTCD4315E1PCL support DDM / digital diagnostics?
Yes. I2C management interface. Your switch can read live temperature, voltage, laser bias and Tx/Rx power.
Which fiber and connector does the FTCD4315E1PCL use?
The FTCD4315E1PCL works at 1310nm CWDM4 over Duplex SMF, LC. CWDM/DWDM optics must match the channel of your mux/demux port. Both ends of a link must use the same optical standard.
Will the FTCD4315E1PCL work in my Cisco, Juniper, Arista or HPE switch?
The FTCD4315E1PCL follows the OSFP MSA, so it fits any matching port. It carries Finisar's own EEPROM programming; switches that check the module vendor may need a configuration setting or a vendor-branded optic. Send us your switch model and we confirm before dispatch.
What temperature range is the FTCD4315E1PCL rated for?
The FTCD4315E1PCL is a commercial-temperature part. Choose an industrial (T) variant for outdoor or uncontrolled sites.
What does the FTCD4315E1PCL part number mean?
The FTCD prefix marks Finisar's 400G family. The C letter in the suffix usually marks the commercial temperature grade. The remaining characters identify the optical design and build variant.
Is your FTCD4315E1PCL genuine Finisar?
Yes. Next Gen Networks supplies original Finisar / Coherent modules, not third-party lookalikes or grey-market stock, and shares serial numbers on request.
What is the FTCD4315E1PCL price in India and how do I order?
The Finisar FTCD4315E1PCL price in India depends on quantity, delivery city and current stock. Next Gen Networks supplies it with a GST invoice (input tax credit ready) and pan-India dispatch from New Delhi. Send the part number, quantity and delivery city on WhatsApp +91-7827955775 or email Sales@nextgennetworks.in for a GST quote.
What power does the FTCD4315E1PCL need?
It runs from 3.3 V (3.135–3.465 V) with power dissipation of < 12 W.
