About the Finisar FTLC3351R3PL1
The Finisar FTLC3351R3PL1 (now a Coherent Corp. product, formerly II-VI) is a QSFP28 100G ZR digital coherent optics (DCO), Steelerton DSP - Standard Tx power optical transceiver for 100 Gb/s links at C-band DWDM tunable over SMF duplex (LC), with reach up to up to 300km (amplified). It is a commercial-temperature part. It belongs to Finisar's FTLC3351 family, which has 4 orderable variants that differ by temperature grade, latch, receiver build or wavelength channel. Typical uses: 100G Ethernet data-centre fabrics, DCI, metro aggregation and InfiniBand EDR.
- Built around Coherent Steelerton DSP
- Silicon photonics optical front-end
- Power-optimized tunable laser
- Typical power dissipation under 5W
FTLC3351R3PL1: frequently asked questions
What is the Finisar FTLC3351R3PL1?
The FTLC3351R3PL1 is a Finisar QSFP28 transceiver for 100G ZR digital coherent optics (DCO), Steelerton DSP - Standard Tx power 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 FTLC3351R3PL1?
The FTLC3351R3PL1 is specified for up to up to 300km (amplified) over SMF duplex (LC). 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 FTLC3351R3PL1?
Per the Finisar family datasheet, the FTLC3351R3PL1 transmits −8 dBm (standard Tx output power).
Does the FTLC3351R3PL1 support DDM / digital diagnostics?
Yes. Digital diagnostics; SFF-8636. Your switch can read live temperature, voltage, laser bias and Tx/Rx power.
Which fiber and connector does the FTLC3351R3PL1 use?
The FTLC3351R3PL1 works at C-band DWDM tunable over SMF duplex (LC). Both ends of a link must use the same optical standard.
Will the FTLC3351R3PL1 work in my Cisco, Juniper, Arista or HPE switch?
The FTLC3351R3PL1 follows the QSFP28 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.
FTLC3351R3PL1 vs FTLC3351S3PL1: what is the difference?
Both are in Finisar's FTLC3351 family. They differ in build / application (100G ZR digital coherent optics (DCO), Steelerton DSP - Standard Tx power vs 100G ZR digital coherent optics (DCO), Steelerton DSP - Tx variant S). Pick the variant that matches your temperature, latch and wavelength needs.
What temperature range is the FTLC3351R3PL1 rated for?
The FTLC3351R3PL1 is a commercial-temperature part. Choose an industrial (T) variant for outdoor or uncontrolled sites.
What does the FTLC3351R3PL1 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 FTLC3351R3PL1 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 FTLC3351R3PL1 price in India and how do I order?
The Finisar FTLC3351R3PL1 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 FTLC3351R3PL1 need?
It runs from the standard host supply with power dissipation of < 5 W typical.
