FTLC1154RDPLD: frequently asked questions
What is the Finisar FTLC1154RDPLD?
The FTLC1154RDPLD is a Finisar QSFP28 transceiver for 100G 4WDM eLR4 industrial temperature 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 FTLC1154RDPLD?
The FTLC1154RDPLD is specified for up to 20km 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 FTLC1154RDPLD?
Per the Finisar family datasheet, the FTLC1154RDPLD transmits −4.3 to 4.5 dBm avg per lane and has a receiver sensitivity of −8.6 dBm OMA per lane. Maximum receiver input is Damage threshold 5.5 dBm per lane.
Does the FTLC1154RDPLD support DDM / digital diagnostics?
Yes. I2C management/diagnostics interface. Your switch can read live temperature, voltage, laser bias and Tx/Rx power.
Which fiber and connector does the FTLC1154RDPLD use?
The FTLC1154RDPLD works at LAN-WDM 1295-1310nm over SMF duplex (LC). Both ends of a link must use the same optical standard.
Will the FTLC1154RDPLD work in my Cisco, Juniper, Arista or HPE switch?
The FTLC1154RDPLD 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.
FTLC1154RDPLD vs FTLC1154RDPL: what is the difference?
Both are in Finisar's FTLC1154 family. They differ in reach (20km vs 10km); build / application (100G 4WDM eLR4 industrial temperature vs 100GBASE-LR4 Gen2). Pick the variant that matches your temperature, latch and wavelength needs.
What temperature range is the FTLC1154RDPLD rated for?
The FTLC1154RDPLD is an industrial-temperature part. Industrial grade suits outdoor cabinets, telecom huts and plant floors.
What does the FTLC1154RDPLD part number mean?
The FTLC prefix marks Finisar's 100G family (QSFP28 / CFP / CFP2 / CFP4). The I letter in the suffix usually marks the industrial temperature grade. The remaining characters identify the optical design and build variant.
Is your FTLC1154RDPLD 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 FTLC1154RDPLD price in India and how do I order?
The Finisar FTLC1154RDPLD 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 FTLC1154RDPLD need?
It runs from 3.3 V (3.135–3.465 V) with power dissipation of < 3.5 W (RDPL4 / RDPLC: < 4.5 W).
