FTCE4517E1PCA: frequently asked questions
What is the Finisar FTCE4517E1PCA?
The FTCE4517E1PCA is a Finisar OSFP transceiver for 2x400G DR4 (800G DR8), closed top 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 FTCE4517E1PCA?
The FTCE4517E1PCA 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 FTCE4517E1PCA?
Per the Finisar family datasheet, the FTCE4517E1PCA 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 FTCE4517E1PCA 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 FTCE4517E1PCA use?
The FTCE4517E1PCA works at 1310nm EML x8 over Parallel SMF, dual MPO12. Both ends of a link must use the same optical standard.
Will the FTCE4517E1PCA work in my Cisco, Juniper, Arista or HPE switch?
The FTCE4517E1PCA 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.
FTCE4517E1PCA vs FTCE4517E1PCM: what is the difference?
Both are in Finisar's FTCE4517 family. They differ in build / application (2x400G DR4 (800G DR8), closed top vs 800G DR8). Pick the variant that matches your temperature, latch and wavelength needs.
What temperature range is the FTCE4517E1PCA rated for?
The FTCE4517E1PCA is a commercial-temperature part. Choose an industrial (T) variant for outdoor or uncontrolled sites.
What does the FTCE4517E1PCA part number mean?
The FTCE prefix marks Finisar's 800G 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 FTCE4517E1PCA 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 FTCE4517E1PCA price in India and how do I order?
The Finisar FTCE4517E1PCA 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 FTCE4517E1PCA need?
It runs from 3.3 V (3.135–3.465 V) with power dissipation of < 17 W.
