FTLC1121RDNL: frequently asked questions
What is the Finisar FTLC1121RDNL?
The FTLC1121RDNL is a Finisar CFP2 transceiver for 100GBASE-LR4 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 FTLC1121RDNL?
The FTLC1121RDNL is specified for up to 10km over SMF duplex (LC). Long-reach optics may need an attenuator on short links; we can advise based on your link loss.
Which fiber and connector does the FTLC1121RDNL use?
The FTLC1121RDNL works at LAN-WDM 1295-1310nm over SMF duplex (LC). Both ends of a link must use the same optical standard.
Does the FTLC1121RDNL support DDM / digital diagnostics?
Yes. Digital (MDIO). Your switch can read live temperature, voltage, laser bias and Tx/Rx power.
Will the FTLC1121RDNL work in my Cisco, Juniper, Arista or HPE switch?
The FTLC1121RDNL 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.
FTLC1121RDNL vs FTLC1121SDNL: what is the difference?
Both are in Finisar's FTLC1121 family. They differ in build / application (100GBASE-LR4 vs 100GBASE-LR4 + OTU4 dual rate Gen2). Pick the variant that matches your temperature, latch and wavelength needs.
What does the FTLC1121RDNL part number mean?
The FTLC prefix marks Finisar's 100G family (QSFP28 / CFP / CFP2 / CFP4). The remaining characters identify the optical design and build variant.
Is your FTLC1121RDNL 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 FTLC1121RDNL price in India and how do I order?
The Finisar FTLC1121RDNL 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 FTLC1121RDNL need?
It runs from 3.3 V.
