FTCD4533E2PLM-4A: frequently asked questions
What is the Finisar FTCD4533E2PLM-4A?
The FTCD4533E2PLM-4A is a Finisar QSFP-DD transceiver for 400G DR4+ (400G mode preset) 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 FTCD4533E2PLM-4A?
The FTCD4533E2PLM-4A 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 FTCD4533E2PLM-4A?
Per the Finisar family datasheet, the FTCD4533E2PLM-4A 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 FTCD4533E2PLM-4A 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 FTCD4533E2PLM-4A use?
The FTCD4533E2PLM-4A works at 1310nm EML x4 over Parallel SMF, MPO12. Both ends of a link must use the same optical standard.
Will the FTCD4533E2PLM-4A work in my Cisco, Juniper, Arista or HPE switch?
The FTCD4533E2PLM-4A 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.
FTCD4533E2PLM-4A vs FTCD4533E2PCM: what is the difference?
Both are in Finisar's FTCD4533 family. They differ in build / application (400G DR4+ (400G mode preset) vs 400G DR4+ / 4x100G-FR1 (4x100G mode)). Pick the variant that matches your temperature, latch and wavelength needs.
What does the FTCD4533E2PLM-4A part number mean?
The FTCD prefix marks Finisar's 400G family. The remaining characters identify the optical design and build variant.
Is your FTCD4533E2PLM-4A 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 FTCD4533E2PLM-4A price in India and how do I order?
The Finisar FTCD4533E2PLM-4A 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 FTCD4533E2PLM-4A 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).
