- Built-in digital diagnostic functions
- Metal enclosure, for lower EMI
FTLF1436P3BCL: frequently asked questions
What is the Finisar FTLF1436P3BCL?
The FTLF1436P3BCL is a Finisar SFP28 transceiver for 25GBASE-LR single-rate 0-70C at 25 Gb/s. Finisar is now part of Coherent Corp. (formerly II-VI), and the part number is unchanged. It is used for 25G Ethernet server and leaf links, 5G fronthaul (eCPRI) and 10G-to-25G upgrades.
What is the maximum distance of the FTLF1436P3BCL?
The FTLF1436P3BCL is specified for up to 10km over SMF. Long-reach optics may need an attenuator on short links; we can advise based on your link loss.
Which fiber and connector does the FTLF1436P3BCL use?
The FTLF1436P3BCL works at 1310nm over SMF. Both ends of a link must use the same optical standard.
Does the FTLF1436P3BCL support DDM / digital diagnostics?
Yes. Built-in digital diagnostic functions. Your switch can read live temperature, voltage, laser bias and Tx/Rx power.
Will the FTLF1436P3BCL work in my Cisco, Juniper, Arista or HPE switch?
The FTLF1436P3BCL follows the SFP28 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.
FTLF1436P3BCL vs FTLF1436P3BCV: what is the difference?
Both are in Finisar's FTLF1436P3 family. They differ in build / application (25GBASE-LR single-rate 0-70C vs 25GBASE-LR dual-rate (listing only)). Pick the variant that matches your temperature, latch and wavelength needs.
What temperature range is the FTLF1436P3BCL rated for?
The FTLF1436P3BCL is a commercial-temperature part. Choose an industrial (T) variant for outdoor or uncontrolled sites.
What does the FTLF1436P3BCL part number mean?
The FTLF prefix marks Finisar's SFP / SFP28 / SFP56 family (incl. Fibre Channel). The C letter in the suffix usually marks the commercial temperature grade. The remaining characters identify the optical design and build variant.
Is your FTLF1436P3BCL 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 FTLF1436P3BCL price in India and how do I order?
The Finisar FTLF1436P3BCL 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 FTLF1436P3BCL need?
It runs from 3.3 V with power dissipation of 1.5 W max with established link.
