FTLF1428P2BNV: frequently asked questions
What is the Finisar FTLF1428P2BNV?
The FTLF1428P2BNV is a Finisar SFP+ transceiver for 8GFC longwave (Gen-1) at 8.5 Gb/s. Finisar is now part of Coherent Corp. (formerly II-VI), and the part number is unchanged. It is used for 8G Fibre Channel storage networks.
What is the maximum distance of the FTLF1428P2BNV?
The FTLF1428P2BNV is specified for up to 10km over Duplex SMF 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 FTLF1428P2BNV?
Per the Finisar family datasheet, the FTLF1428P2BNV transmits −8.4 to +0.5 dBm @8.5G; −8.4 to −3 dBm @2.125/4.25G and has a receiver sensitivity of 0.042 mW @8.5G, 0.029 mW @4.25G, 0.015 mW @2.125G (OMA). Maximum receiver input is +0.5 dBm.
Does the FTLF1428P2BNV support DDM / digital diagnostics?
Yes. Digital diagnostics via 2-wire serial interface (temperature, bias, optical power, alarms/warnings). Your switch can read live temperature, voltage, laser bias and Tx/Rx power.
Which fiber and connector does the FTLF1428P2BNV use?
The FTLF1428P2BNV works at 1310nm over Duplex SMF LC. Both ends of a link must use the same optical standard.
Will the FTLF1428P2BNV work in my Cisco, Juniper, Arista or HPE switch?
The FTLF1428P2BNV follows the SFP+ 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.
FTLF1428P2BNV vs FTLF1428P3BNV: what is the difference?
Both are in Finisar's FTLF1428 family. They differ in build / application (8GFC longwave (Gen-1) vs 8GFC longwave). Pick the variant that matches your temperature, latch and wavelength needs.
What temperature range is the FTLF1428P2BNV rated for?
The FTLF1428P2BNV is an extended-temperature part. Choose an industrial (T) variant for outdoor or uncontrolled sites.
What does the FTLF1428P2BNV part number mean?
The FTLF prefix marks Finisar's SFP / SFP28 / SFP56 family (incl. Fibre Channel). The E letter in the suffix usually marks the extended temperature grade. The remaining characters identify the optical design and build variant.
Is your FTLF1428P2BNV 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 FTLF1428P2BNV price in India and how do I order?
The Finisar FTLF1428P2BNV 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 FTLF1428P2BNV need?
It runs from 3.3 V (3.00–3.60 V).
