About the Finisar FTL-8519-3D
The Finisar FTL-8519-3D (now a Coherent Corp. product, formerly II-VI) is a GBIC 1000BASE-SX / 1G FC optical transceiver for 1 Gb/s links at 850nm over MMF, with reach up to 550m. It is an extended-temperature part rated −10 to 85 °C. It belongs to Finisar's FTL-8519-3D family, which has 2 orderable variants that differ by temperature grade, latch, receiver build or wavelength channel. This is a legacy Finisar part; we help buyers find remaining stock or a current Coherent alternative. Typical uses: Fast/Gigabit Ethernet, SONET/SDH OC-3/OC-12, campus and access links, and legacy network upgrades.

FTL-8519-3D: frequently asked questions
What is the Finisar FTL-8519-3D?
The FTL-8519-3D is a Finisar GBIC transceiver for 1000BASE-SX / 1G FC at 1 Gb/s. Finisar is now part of Coherent Corp. (formerly II-VI), and the part number is unchanged. It is used for Fast/Gigabit Ethernet, SONET/SDH OC-3/OC-12, campus and access links, and legacy network upgrades.
What is the maximum distance of the FTL-8519-3D?
The FTL-8519-3D is specified for up to 550m over MMF. Long-reach optics may need an attenuator on short links; we can advise based on your link loss.
Which fiber and connector does the FTL-8519-3D use?
The FTL-8519-3D works at 850nm over MMF. Both ends of a link must use the same optical standard.
Will the FTL-8519-3D work in my Cisco, Juniper, Arista or HPE switch?
The FTL-8519-3D follows the GBIC 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.
FTL-8519-3D vs FTL-8519-3D-DD: what is the difference?
Both are in Finisar's FTL-8519-3D family. They differ in build / application (1000BASE-SX / 1G FC vs 1000BASE-SX / 1G FC, digital diagnostics). Pick the variant that matches your temperature, latch and wavelength needs.
What temperature range is the FTL-8519-3D rated for?
The FTL-8519-3D is an extended-temperature part rated −10 to 85 °C. Choose an industrial (T) variant for outdoor or uncontrolled sites.
What does the FTL-8519-3D part number mean?
The FTL- prefix marks Finisar's GBIC family. The E letter in the suffix usually marks the extended temperature grade. The remaining characters identify the optical design and build variant.
Is the FTL-8519-3D still available?
The FTL-8519-3D is a legacy Finisar part, so new production is limited or ended. Next Gen Networks helps source remaining genuine stock and can suggest a current Coherent alternative with the same reach and wavelength.
What is the FTL-8519-3D price in India and how do I order?
The Finisar FTL-8519-3D 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.
