FTCD1323E1PCL: frequently asked questions
What is the Finisar FTCD1323E1PCL?
The FTCD1323E1PCL is a Finisar QSFP-DD transceiver for 400GBASE-LR8 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 FTCD1323E1PCL?
The FTCD1323E1PCL is specified for up to 10 km over Duplex SMF, LC. Long-reach optics may need an attenuator on short links; we can advise based on your link loss.
Which fiber and connector does the FTCD1323E1PCL use?
The FTCD1323E1PCL works at 1310nm LAN-WDM x8 over Duplex SMF, LC. Both ends of a link must use the same optical standard.
Does the FTCD1323E1PCL support DDM / digital diagnostics?
Yes. Digital. Your switch can read live temperature, voltage, laser bias and Tx/Rx power.
Will the FTCD1323E1PCL work in my Cisco, Juniper, Arista or HPE switch?
The FTCD1323E1PCL follows the QSFP-DD 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 FTCD1323E1PCL rated for?
The FTCD1323E1PCL is a commercial-temperature part. Choose an industrial (T) variant for outdoor or uncontrolled sites.
What does the FTCD1323E1PCL 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 FTCD1323E1PCL 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 FTCD1323E1PCL price in India and how do I order?
The Finisar FTCD1323E1PCL 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 FTCD1323E1PCL need?
It runs from 3.3 V.
