About the Finisar FTRJ8519P1WNL
The Finisar FTRJ8519P1WNL (now a Coherent Corp. product, formerly II-VI) is a SFP 1G-2G FC / GbE (2.125G), non-RoHS optical transceiver for up to 2.125 Gb/s links at 850nm over MMF, with reach up to 500m. It is an extended-temperature part rated −20 to 90 °C. It belongs to Finisar's FTRJ8519P1 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: Gigabit Ethernet, 1/2/4G Fibre Channel SAN, SONET OC-48 / STM-16 and CWDM/DWDM metro links.
- Hot-pluggable SFP footprint
- Built-in digital diagnostic functions
- Very low jitter
- Metal enclosure, for lower EMI
- Single 3.3 V power supply
- Extended operating temperature range: −20 °C to 90 °C
FTRJ8519P1WNL: frequently asked questions
What is the Finisar FTRJ8519P1WNL?
The FTRJ8519P1WNL is a Finisar SFP transceiver for 1G-2G FC / GbE (2.125G), non-RoHS 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 FTRJ8519P1WNL?
The FTRJ8519P1WNL is specified for up to 500m over MMF. 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 FTRJ8519P1WNL?
Per the Finisar family datasheet, the FTRJ8519P1WNL transmits −9 to −3.5 dBm and has a receiver sensitivity of −20 dBm max (−22 typ) @ 1.0625/1.25 Gb/s; −18 dBm max (−20 typ) @ 2.125 Gb/s. Maximum receiver input is 0 dBm.
Does the FTRJ8519P1WNL support DDM / digital diagnostics?
Yes. Digital diagnostics over 2-wire serial (temp, voltage, bias, Tx/Rx power, alarm/warning flags). Your switch can read live temperature, voltage, laser bias and Tx/Rx power.
Which fiber and connector does the FTRJ8519P1WNL use?
The FTRJ8519P1WNL works at 850nm over MMF. Both ends of a link must use the same optical standard.
Will the FTRJ8519P1WNL work in my Cisco, Juniper, Arista or HPE switch?
The FTRJ8519P1WNL 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.
FTRJ8519P1WNL vs FTRJ8519P1BNL: what is the difference?
Both are in Finisar's FTRJ8519P1 family and share the same core optics; the suffix marks a different build option (latch, receiver or ordering variant). Pick the variant that matches your temperature, latch and wavelength needs.
What temperature range is the FTRJ8519P1WNL rated for?
The FTRJ8519P1WNL is an extended-temperature part rated −20 to 90 °C. Choose an industrial (T) variant for outdoor or uncontrolled sites.
What does the FTRJ8519P1WNL part number mean?
The FTRJ prefix marks Finisar's earlier-generation SFP / SFF 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 FTRJ8519P1WNL still available?
The FTRJ8519P1WNL 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 FTRJ8519P1WNL price in India and how do I order?
The Finisar FTRJ8519P1WNL 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 FTRJ8519P1WNL need?
It runs from 3.3 V (3.0–3.6 V) with power dissipation of < 750 mW (180 typ / 240 max mA).
