About the Finisar FTCD8613E1PCM
The Finisar FTCD8613E1PCM (now a Coherent Corp. product, formerly II-VI) is a QSFP-DD 400GBASE-SR8 optical transceiver for 400 Gb/s links at 850nm VCSEL x8 over Parallel MMF, MPO16, with reach up to 70 m OM3 / 100 m OM4. It is a commercial-temperature part. It belongs to Finisar's FTCD8613 family, which has 3 orderable variants that differ by temperature grade, latch, receiver build or wavelength channel. This is a legacy Finisar part; we help buyers find remaining stock or a current Coherent alternative. Typical uses: 400G data-centre spine, AI/ML clusters and 400ZR / ZR+ coherent DCI.
- Hot-pluggable QSFP-DD form factor
- 8x50G PAM4 VCSEL transmitter
- MPO-16 APC connector
- I2C management interface
- Breakout: 2x200GBASE-SR4, 4x100GBASE-SR2, 8x50GBASE-SR (E2)
FTCD8613E1PCM: frequently asked questions
What is the Finisar FTCD8613E1PCM?
The FTCD8613E1PCM is a Finisar QSFP-DD transceiver for 400GBASE-SR8 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 FTCD8613E1PCM?
The FTCD8613E1PCM is specified for up to 70 m OM3 / 100 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 FTCD8613E1PCM?
Per the Finisar family datasheet, the FTCD8613E1PCM transmits −6.5 to 4 dBm per lane and has a receiver sensitivity of −3.4 dBm stressed OMAouter per lane. Maximum receiver input is 5 dBm damage threshold.
Does the FTCD8613E1PCM support DDM / digital diagnostics?
Yes. I2C management interface (CMIS 4.0). Your switch can read live temperature, voltage, laser bias and Tx/Rx power.
Which fiber and connector does the FTCD8613E1PCM use?
The FTCD8613E1PCM works at 850nm VCSEL x8 over Parallel MMF, MPO16. Both ends of a link must use the same optical standard.
Will the FTCD8613E1PCM work in my Cisco, Juniper, Arista or HPE switch?
The FTCD8613E1PCM 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.
FTCD8613E1PCM vs FTCD8613E2PCM: what is the difference?
Both are in Finisar's FTCD8613 family. They differ in reach (70 m OM3 / 100 m OM4 vs 100 m OM4); build / application (400GBASE-SR8 vs 400GBASE-SR8 (also 2x200G-SR4/4x100G-SR2/8x50G)). Pick the variant that matches your temperature, latch and wavelength needs.
What temperature range is the FTCD8613E1PCM rated for?
The FTCD8613E1PCM is a commercial-temperature part. Choose an industrial (T) variant for outdoor or uncontrolled sites.
What does the FTCD8613E1PCM 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 the FTCD8613E1PCM still available?
The FTCD8613E1PCM is a legacy Finisar part, so new production is limited or ended. Next Gen Networks helps source remaining genuine stock and can suggest a current Coherent alternative with the same reach and wavelength.
What is the FTCD8613E1PCM price in India and how do I order?
The Finisar FTCD8613E1PCM 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 FTCD8613E1PCM need?
It runs from 3.3 V (3.135–3.465 V) with power dissipation of < 10 W (E1); < 9 W (E2).
