About the Finisar FCM-8519-1-T4
The Finisar FCM-8519-1-T4 (now a Coherent Corp. product, formerly II-VI) is a GBIC (copper) Copper GBIC copper module for 1 Gb/s links over Copper, with reach up to 100m Cat5 (1000BASE-T parts). It belongs to Finisar's FCM-85xx family, which has 4 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.
- Complies with GBIC Specification Revision 5.4
- Compatible with Gigabit Ethernet 1000BASE-CX
- Supports Fibre Channel FC-PH3
FCM-8519-1-T4: frequently asked questions
What is the Finisar FCM-8519-1-T4?
The FCM-8519-1-T4 is a Finisar GBIC (copper) transceiver for Copper GBIC 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 FCM-8519-1-T4?
The FCM-8519-1-T4 is specified for up to 100m Cat5 (1000BASE-T parts) over Copper. It is a copper module, so no optical power budget applies.
Which cable does the FCM-8519-1-T4 use?
It is a copper module with an RJ-45 jack, so standard twisted-pair cabling plugs straight in.
Will the FCM-8519-1-T4 work in my Cisco, Juniper, Arista or HPE switch?
The FCM-8519-1-T4 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.
FCM-8519-1-T4 vs FCM-8520-3: what is the difference?
Both are in Finisar's FCM-85xx family. They differ in build / application (Copper GBIC vs 1000BASE-T copper GBIC). Pick the variant that matches your temperature, latch and wavelength needs.
What does the FCM-8519-1-T4 part number mean?
The FCM- prefix marks Finisar's copper GBIC family. The remaining characters identify the optical design and build variant.
Is the FCM-8519-1-T4 still available?
The FCM-8519-1-T4 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 FCM-8519-1-T4 price in India and how do I order?
The Finisar FCM-8519-1-T4 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.
