FTCD8633E1PCM: frequently asked questions
What is the Finisar FTCD8633E1PCM?
The FTCD8633E1PCM is a Finisar QSFP-DD transceiver for 400GBASE-SR4.2 BiDi (4x100G BiDi breakout) 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 FTCD8633E1PCM?
The FTCD8633E1PCM is specified for up to 70 m OM3 / 100 m OM4 / 150 m OM5 over Parallel MMF, 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 FTCD8633E1PCM?
Per the Finisar family datasheet, the FTCD8633E1PCM transmits −6.2 to 4 dBm per lane and has a receiver sensitivity of max(−6.6, SECQ − 8) dBm OMAouter. Maximum receiver input is 5 dBm damage threshold.
Does the FTCD8633E1PCM support DDM / digital diagnostics?
Yes. I2C management interface. Your switch can read live temperature, voltage, laser bias and Tx/Rx power.
Which fiber and connector does the FTCD8633E1PCM use?
The FTCD8633E1PCM works at 850/910nm over Parallel MMF, MPO12. Both ends of a link must use the same optical standard.
Will the FTCD8633E1PCM work in my Cisco, Juniper, Arista or HPE switch?
The FTCD8633E1PCM 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.
What temperature range is the FTCD8633E1PCM rated for?
The FTCD8633E1PCM is a commercial-temperature part. Choose an industrial (T) variant for outdoor or uncontrolled sites.
What does the FTCD8633E1PCM part number mean?
The FTCD prefix marks Finisar's 400G 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 FTCD8633E1PCM 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 FTCD8633E1PCM price in India and how do I order?
The Finisar FTCD8633E1PCM 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 FTCD8633E1PCM need?
It runs from 3.3 V (3.135–3.465 V) with power dissipation of < 9 W.
