FTLC8221RFNM: frequently asked questions
What is the Finisar FTLC8221RFNM?
The FTLC8221RFNM is a Finisar CFP2 transceiver for 10x10GBASE-SR / extended-reach 100GBASE-SR10 at 100 Gb/s. Finisar is now part of Coherent Corp. (formerly II-VI), and the part number is unchanged. It is used for 100G Ethernet data-centre fabrics, DCI, metro aggregation and InfiniBand EDR.
What is the maximum distance of the FTLC8221RFNM?
The FTLC8221RFNM is specified for up to 300m over MMF parallel (MPO-24). 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 FTLC8221RFNM?
Per the Finisar family datasheet, the FTLC8221RFNM transmits SCNM: −7.6 to 2.4 dBm avg per lane; RFNM: max +0.5 dBm and has a receiver sensitivity of SCNM: −8.7 dBm OMA back-to-back; RFNM: −11.1 dBm b2b / −7.5 dBm stressed. Maximum receiver input is Damage threshold 5.5 dBm per lane.
Does the FTLC8221RFNM support DDM / digital diagnostics?
Yes. MDIO management interface with Tx/Rx optical power monitoring. Your switch can read live temperature, voltage, laser bias and Tx/Rx power.
Which fiber and connector does the FTLC8221RFNM use?
The FTLC8221RFNM works at 850nm over MMF parallel (MPO-24). Both ends of a link must use the same optical standard.
Will the FTLC8221RFNM work in my Cisco, Juniper, Arista or HPE switch?
The FTLC8221RFNM follows the CFP2 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.
FTLC8221RFNM vs FTLC8221SCNM: what is the difference?
Both are in Finisar's FTLC8221 family. They differ in reach (300m vs 100m); build / application (10x10GBASE-SR / extended-reach 100GBASE-SR10 vs 100GBASE-SR10 + OTN multirate). Pick the variant that matches your temperature, latch and wavelength needs.
What temperature range is the FTLC8221RFNM rated for?
The FTLC8221RFNM is a commercial-temperature part. Choose an industrial (T) variant for outdoor or uncontrolled sites.
What does the FTLC8221RFNM part number mean?
The FTLC prefix marks Finisar's 100G family (QSFP28 / CFP / CFP2 / CFP4). The C letter in the suffix usually marks the commercial temperature grade. The remaining characters identify the optical design and build variant.
Is your FTLC8221RFNM 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 FTLC8221RFNM price in India and how do I order?
The Finisar FTLC8221RFNM 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 FTLC8221RFNM need?
It runs from 3.3 V (3.13–3.47 V) with power dissipation of < 4 W.
