About the Finisar FTLF8519P2BCL
The Finisar FTLF8519P2BCL (now a Coherent Corp. product, formerly II-VI) is a SFP 1000BASE-SX / 1G-2G FC (2.125G) optical transceiver for up to 2.125 Gb/s links at 850nm over MMF, with reach up to 550m. It is a commercial-temperature part. It belongs to Finisar's FTLF8519P2 family, which has 6 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: Gigabit Ethernet, 1/2/4G Fibre Channel SAN, SONET OC-48 / STM-16 and CWDM/DWDM metro links.

FTLF8519P2BCL: frequently asked questions
What is the Finisar FTLF8519P2BCL?
The FTLF8519P2BCL is a Finisar SFP transceiver for 1000BASE-SX / 1G-2G FC (2.125G) at up to 2.125 Gb/s. Finisar is now part of Coherent Corp. (formerly II-VI), and the part number is unchanged. It is used for Gigabit Ethernet, 1/2/4G Fibre Channel SAN, SONET OC-48 / STM-16 and CWDM/DWDM metro links.
What is the maximum distance of the FTLF8519P2BCL?
The FTLF8519P2BCL 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 FTLF8519P2BCL use?
The FTLF8519P2BCL works at 850nm over MMF. Both ends of a link must use the same optical standard.
Will the FTLF8519P2BCL work in my Cisco, Juniper, Arista or HPE switch?
The FTLF8519P2BCL 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.
FTLF8519P2BCL vs FTLF8519P2BNL: what is the difference?
Both are in Finisar's FTLF8519P2 family. They differ in temperature grade (commercial vs extended). Pick the variant that matches your temperature, latch and wavelength needs.
What temperature range is the FTLF8519P2BCL rated for?
The FTLF8519P2BCL is a commercial-temperature part (per Finisar's part-number temperature code). Choose an industrial (T) variant for outdoor or uncontrolled sites.
What does the FTLF8519P2BCL 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 the FTLF8519P2BCL still available?
The FTLF8519P2BCL 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 FTLF8519P2BCL price in India and how do I order?
The Finisar FTLF8519P2BCL 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.
