FTCD4533E3PCM: frequently asked questions
What is the Finisar FTCD4533E3PCM?
The FTCD4533E3PCM is a Finisar QSFP-DD transceiver for 400G DR4+ Gen3 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 FTCD4533E3PCM?
The FTCD4533E3PCM is specified for up to 2 km over Parallel SMF, MPO12. 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 FTCD4533E3PCM?
Per the Finisar family datasheet, the FTCD4533E3PCM transmits −3.1 (informative) to 4 dBm avg per lane; OMAouter max 4.2 dBm and has a receiver sensitivity of −4.5 dBm OMAouter (TECQ < 1.4 dB); −5.9 + TECQ dBm (1.4–3.4 dB). Maximum receiver input is 5 dBm damage threshold.
Does the FTCD4533E3PCM support DDM / digital diagnostics?
Yes. I2C-based diagnostics interface. Your switch can read live temperature, voltage, laser bias and Tx/Rx power.
Which fiber and connector does the FTCD4533E3PCM use?
The FTCD4533E3PCM works at 1310nm EML x4 over Parallel SMF, MPO12. Both ends of a link must use the same optical standard.
Will the FTCD4533E3PCM work in my Cisco, Juniper, Arista or HPE switch?
The FTCD4533E3PCM 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.
FTCD4533E3PCM vs FTCD4533E2PCM: what is the difference?
Both are in Finisar's FTCD4533 family. They differ in build / application (400G DR4+ Gen3 vs 400G DR4+ / 4x100G-FR1 (4x100G mode)). Pick the variant that matches your temperature, latch and wavelength needs.
What temperature range is the FTCD4533E3PCM rated for?
The FTCD4533E3PCM is a commercial-temperature part. Choose an industrial (T) variant for outdoor or uncontrolled sites.
What does the FTCD4533E3PCM 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 FTCD4533E3PCM 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 FTCD4533E3PCM price in India and how do I order?
The Finisar FTCD4533E3PCM 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 FTCD4533E3PCM need?
It runs from 3.3 V (3.135–3.465 V) with power dissipation of < 12 W c-temp / < 10 W limited temp (E2); < 8 W (E3, Gen3).
