FTLC1156SDPL: frequently asked questions
What is the Finisar FTLC1156SDPL?
The FTLC1156SDPL is a Finisar QSFP28 transceiver for 100G LR4 / OTU4 / EDR multirate 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 FTLC1156SDPL?
The FTLC1156SDPL 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 FTLC1156SDPL?
Per the Finisar family datasheet, the FTLC1156SDPL 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.
Does the FTLC1156SDPL support DDM / digital diagnostics?
Yes. Digital diagnostics via I2C. Your switch can read live temperature, voltage, laser bias and Tx/Rx power.
Which fiber and connector does the FTLC1156SDPL use?
The FTLC1156SDPL works at LAN-WDM 1295-1310nm over SMF duplex (LC). Both ends of a link must use the same optical standard.
Will the FTLC1156SDPL work in my Cisco, Juniper, Arista or HPE switch?
The FTLC1156SDPL 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.
FTLC1156SDPL vs FTLC1156RDPL: what is the difference?
Both are in Finisar's FTLC1156 family. They differ in build / application (100G LR4 / OTU4 / EDR multirate vs 100GBASE-LR4). Pick the variant that matches your temperature, latch and wavelength needs.
What temperature range is the FTLC1156SDPL rated for?
The FTLC1156SDPL is a commercial-temperature part. Choose an industrial (T) variant for outdoor or uncontrolled sites.
What does the FTLC1156SDPL 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 FTLC1156SDPL 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 FTLC1156SDPL price in India and how do I order?
The Finisar FTLC1156SDPL 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 FTLC1156SDPL need?
It runs from 3.3 V (3.135–3.465 V) with power dissipation of 3.5 W max.
