FTCE8627E1PCM-1Y: frequently asked questions
What is the Finisar FTCE8627E1PCM-1Y?
The FTCE8627E1PCM-1Y is a Finisar OSFP transceiver for 800G VR8, 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 FTCE8627E1PCM-1Y?
The FTCE8627E1PCM-1Y 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-1Y?
Per the Finisar family datasheet, the FTCE8627E1PCM-1Y 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-1Y 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-1Y use?
The FTCE8627E1PCM-1Y works at 850nm VCSEL x8 over Parallel MMF, MPO16. Both ends of a link must use the same optical standard.
Will the FTCE8627E1PCM-1Y work in my Cisco, Juniper, Arista or HPE switch?
The FTCE8627E1PCM-1Y 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-1Y vs FTCE8627E1PCA: what is the difference?
Both are in Finisar's FTCE8627 family. They differ in build / application (800G VR8, closed top vs 2x400G VR4 (802.3db), closed top). Pick the variant that matches your temperature, latch and wavelength needs.
What temperature range is the FTCE8627E1PCM-1Y rated for?
The FTCE8627E1PCM-1Y is a commercial-temperature part. Choose an industrial (T) variant for outdoor or uncontrolled sites.
What does the FTCE8627E1PCM-1Y 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-1Y 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-1Y price in India and how do I order?
The Finisar FTCE8627E1PCM-1Y 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-1Y need?
It runs from 3.3 V (3.135–3.465 V) with power dissipation of < 16 W.
