FTLC1155RGPLC: frequently asked questions
What is the Finisar FTLC1155RGPLC?
The FTLC1155RGPLC is a Finisar QSFP28 transceiver for 100G eCWDM4 extended 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 FTLC1155RGPLC?
The FTLC1155RGPLC 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.
What is the optical power budget of the FTLC1155RGPLC?
Per the Finisar family datasheet, the FTLC1155RGPLC transmits Avg max 2.5 dBm per lane and has a receiver sensitivity of −10 dBm OMA unstressed; −7.3 dBm stressed. Maximum receiver input is Saturation 2.5 dBm OMA; damage threshold 3.5 dBm per lane.
Does the FTLC1155RGPLC 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 FTLC1155RGPLC use?
The FTLC1155RGPLC works at CWDM 1271-1331nm over SMF duplex (LC). CWDM/DWDM optics must match the channel of your mux/demux port. Both ends of a link must use the same optical standard.
Will the FTLC1155RGPLC work in my Cisco, Juniper, Arista or HPE switch?
The FTLC1155RGPLC 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.
FTLC1155RGPLC vs FTLC1155RGPL: what is the difference?
Both are in Finisar's FTLC1155 family. They differ in reach (10km vs 2km); build / application (100G eCWDM4 extended temperature vs 100G CWDM4 Gen2). Pick the variant that matches your temperature, latch and wavelength needs.
What temperature range is the FTLC1155RGPLC rated for?
The FTLC1155RGPLC is an extended-temperature part. Choose an industrial (T) variant for outdoor or uncontrolled sites.
What does the FTLC1155RGPLC part number mean?
The FTLC prefix marks Finisar's 100G family (QSFP28 / CFP / CFP2 / CFP4). The E letter in the suffix usually marks the extended temperature grade. The remaining characters identify the optical design and build variant.
Is your FTLC1155RGPLC 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 FTLC1155RGPLC price in India and how do I order?
The Finisar FTLC1155RGPLC 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 FTLC1155RGPLC need?
It runs from 3.3 V (3.135–3.465 V) with power dissipation of < 3.5 W (extended/industrial-temp variants < 4.5 W).
