FTCE4517E1PxA-2N: frequently asked questions
What is the Finisar FTCE4517E1PxA-2N?
The FTCE4517E1PxA-2N is a Finisar OSFP (RHS) transceiver for 2x400G DR4, riding heatsink at 800 Gb/s. Finisar is now part of Coherent Corp. (formerly II-VI), and the part number is unchanged. It is used for 800G AI/ML back-end fabrics, hyperscale spine layers and 800ZR coherent DCI.
What is the maximum distance of the FTCE4517E1PxA-2N?
The FTCE4517E1PxA-2N is specified for up to 500 m over Parallel SMF, dual 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 FTCE4517E1PxA-2N?
Per the Finisar family datasheet, the FTCE4517E1PxA-2N transmits −2.9 dBm min (informative) to 4 dBm max avg per lane; OMAouter −0.8 to 4.2 dBm and has a receiver sensitivity of −4.4 dBm OMAouter (per lane); stressed −1.9 dBm. Maximum receiver input is 5 dBm damage threshold (per lane).
Does the FTCE4517E1PxA-2N support DDM / digital diagnostics?
Yes. I2C; CMIS 4.0 per MSA (CMIS 5.x optional on PxM). Your switch can read live temperature, voltage, laser bias and Tx/Rx power.
Which fiber and connector does the FTCE4517E1PxA-2N use?
The FTCE4517E1PxA-2N works at 1310nm EML x8 over Parallel SMF, dual MPO12. Both ends of a link must use the same optical standard.
Will the FTCE4517E1PxA-2N work in my Cisco, Juniper, Arista or HPE switch?
The FTCE4517E1PxA-2N follows the OSFP 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.
FTCE4517E1PxA-2N vs FTCE4517E1PCM: what is the difference?
Both are in Finisar's FTCE4517 family. They differ in form factor (OSFP (RHS) vs OSFP); build / application (2x400G DR4, riding heatsink vs 800G DR8). Pick the variant that matches your temperature, latch and wavelength needs.
What does the FTCE4517E1PxA-2N part number mean?
The FTCE prefix marks Finisar's 800G family. The remaining characters identify the optical design and build variant.
Is your FTCE4517E1PxA-2N 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 FTCE4517E1PxA-2N price in India and how do I order?
The Finisar FTCE4517E1PxA-2N 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 FTCE4517E1PxA-2N need?
It runs from 3.3 V (3.135–3.465 V) with power dissipation of < 17 W.
