About the Finisar FTCD1324E1BCL
The Finisar FTCD1324E1BCL (now a Coherent Corp. product, formerly II-VI) is a CFP8 400GBASE-FR8 optical transceiver for 400 Gb/s links at 1310nm LAN-WDM x8 over Duplex SMF, LC, with reach up to 2 km. It is a commercial-temperature part. This is a legacy Finisar part; we help buyers find remaining stock or a current Coherent alternative. Typical uses: 400G data-centre spine, AI/ML clusters and 400ZR / ZR+ coherent DCI.
- Hot-pluggable CFP8 form factor
- Supports 425Gb/s aggregate bit rate
- Power dissipation < 16W
- Maximum link length of 2km on SMF
- 8x50G PAM4 DFB-based LAN-WDM transmitter
- 16x25G electrical interface
FTCD1324E1BCL: frequently asked questions
What is the Finisar FTCD1324E1BCL?
The FTCD1324E1BCL is a Finisar CFP8 transceiver for 400GBASE-FR8 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 FTCD1324E1BCL?
The FTCD1324E1BCL 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 FTCD1324E1BCL?
Per the Finisar family datasheet, the FTCD1324E1BCL transmits −3.5 to 5.3 dBm per lane and has a receiver sensitivity of −5.3 dBm OMAouter per lane. Maximum receiver input is 6.3 dBm damage threshold.
Does the FTCD1324E1BCL support DDM / digital diagnostics?
Yes. MDIO-based diagnostics per CFP MSA. Your switch can read live temperature, voltage, laser bias and Tx/Rx power.
Which fiber and connector does the FTCD1324E1BCL use?
The FTCD1324E1BCL works at 1310nm LAN-WDM x8 over Duplex SMF, LC. Both ends of a link must use the same optical standard.
Will the FTCD1324E1BCL work in my Cisco, Juniper, Arista or HPE switch?
The FTCD1324E1BCL follows the CFP8 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 FTCD1324E1BCL rated for?
The FTCD1324E1BCL is a commercial-temperature part. Choose an industrial (T) variant for outdoor or uncontrolled sites.
What does the FTCD1324E1BCL 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 the FTCD1324E1BCL still available?
The FTCD1324E1BCL is a legacy Finisar part, so new production is limited or ended. Next Gen Networks helps source remaining genuine stock and can suggest a current Coherent alternative with the same reach and wavelength.
What is the FTCD1324E1BCL price in India and how do I order?
The Finisar FTCD1324E1BCL 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 FTCD1324E1BCL need?
It runs from 3.3 V (3.2–3.4 V) with power dissipation of < 16 W.
