FTCD4523E2PLM: frequently asked questions
What is the Finisar FTCD4523E2PLM?
The FTCD4523E2PLM is a Finisar QSFP-DD transceiver for 400GBASE-DR4 (default 4x100G mode) 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 FTCD4523E2PLM?
The FTCD4523E2PLM is specified for up to 500 m 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 FTCD4523E2PLM?
Per the Finisar family datasheet, the FTCD4523E2PLM transmits −0.8 to 4.2 dBm OMA per lane (E2); −2.9 dBm min avg (E3, informative) and has a receiver sensitivity of −4.4 dBm OMA per lane. Maximum receiver input is 5 dBm damage threshold.
Does the FTCD4523E2PLM 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 FTCD4523E2PLM use?
The FTCD4523E2PLM works at 1310nm EML x4 over Parallel SMF, MPO12. Both ends of a link must use the same optical standard.
Will the FTCD4523E2PLM work in my Cisco, Juniper, Arista or HPE switch?
The FTCD4523E2PLM 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.
FTCD4523E2PLM vs FTCD4523E2PCM-4A: what is the difference?
Both are in Finisar's FTCD4523 family. They differ in build / application (400GBASE-DR4 (default 4x100G mode) vs 400GBASE-DR4 (400G mode preset)). Pick the variant that matches your temperature, latch and wavelength needs.
What does the FTCD4523E2PLM part number mean?
The FTCD prefix marks Finisar's 400G family. The remaining characters identify the optical design and build variant.
Is your FTCD4523E2PLM 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 FTCD4523E2PLM price in India and how do I order?
The Finisar FTCD4523E2PLM 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 FTCD4523E2PLM 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).
