FTCE8627E1PCM: frequently asked questions
What is the Finisar FTCE8627E1PCM?
The FTCE8627E1PCM is a Finisar OSFP transceiver for 800G VR8 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 FTCE8627E1PCM?
The FTCE8627E1PCM is specified for up to 50 m OM4 over Parallel MMF, MPO16. 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 FTCE8627E1PCM?
Per the Finisar family datasheet, the FTCE8627E1PCM transmits −4.6 to 4 dBm avg per lane and has a receiver sensitivity of −4.4 dBm (TECQ ≤ 1.8 dB) / −6.2 + TECQ dBm. Maximum receiver input is 5 dBm damage threshold.
Does the FTCE8627E1PCM support DDM / digital diagnostics?
Yes. I2C; CMIS 4.0 per MSA (8x100G default). Your switch can read live temperature, voltage, laser bias and Tx/Rx power.
Which fiber and connector does the FTCE8627E1PCM use?
The FTCE8627E1PCM works at 850nm VCSEL x8 over Parallel MMF, MPO16. Both ends of a link must use the same optical standard.
Will the FTCE8627E1PCM work in my Cisco, Juniper, Arista or HPE switch?
The FTCE8627E1PCM 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.
FTCE8627E1PCM vs FTCE8627E1PCA: what is the difference?
Both are in Finisar's FTCE8627 family. They differ in build / application (800G VR8 vs 2x400G VR4 (802.3db), closed top). Pick the variant that matches your temperature, latch and wavelength needs.
What temperature range is the FTCE8627E1PCM rated for?
The FTCE8627E1PCM is a commercial-temperature part. Choose an industrial (T) variant for outdoor or uncontrolled sites.
What does the FTCE8627E1PCM 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 FTCE8627E1PCM 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 FTCE8627E1PCM price in India and how do I order?
The Finisar FTCE8627E1PCM 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 FTCE8627E1PCM need?
It runs from 3.3 V (3.135–3.465 V) with power dissipation of < 16 W.
