FTRJ-8519-7D: frequently asked questions
What is the Finisar FTRJ-8519-7D?
The FTRJ-8519-7D is a Finisar SFP transceiver for 1000BASE-SX / 1G FC (early SFP) 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 FTRJ-8519-7D?
The FTRJ-8519-7D 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 FTRJ-8519-7D use?
The FTRJ-8519-7D works at 850nm over MMF. Both ends of a link must use the same optical standard.
Will the FTRJ-8519-7D work in my Cisco, Juniper, Arista or HPE switch?
The FTRJ-8519-7D 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.
What does the FTRJ-8519-7D part number mean?
The FTRJ prefix marks Finisar's earlier-generation SFP / SFF family. The remaining characters identify the optical design and build variant.
Is the FTRJ-8519-7D still available?
The FTRJ-8519-7D 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 FTRJ-8519-7D price in India and how do I order?
The Finisar FTRJ-8519-7D 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.
