About the Finisar FTLF1519P1WNL
The Finisar FTLF1519P1WNL (now a Coherent Corp. product, formerly II-VI) is a SFP 1000BASE-ZX / 2G-1G FC (2.125G) optical transceiver for up to 2.125 Gb/s links at 1550nm DFB over SMF, with reach up to 80-90km. It is an extended-temperature part. It belongs to Finisar's FTLF1519P1 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: Gigabit Ethernet, 1/2/4G Fibre Channel SAN, SONET OC-48 / STM-16 and CWDM/DWDM metro links.
- Up to 2.125 Gb/s bi-directional data links
- Hot-pluggable SFP footprint
- Built-in digital diagnostic functions
- Uncooled 1550 nm DFB laser transmitter
- Duplex LC connector
- RoHS compliant and lead-free
FTLF1519P1WNL: frequently asked questions
What is the Finisar FTLF1519P1WNL?
The FTLF1519P1WNL is a Finisar SFP transceiver for 1000BASE-ZX / 2G-1G 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 FTLF1519P1WNL?
The FTLF1519P1WNL is specified for up to 80-90km over SMF. 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 FTLF1519P1WNL?
Per the Finisar family datasheet, the FTLF1519P1WNL transmits 0 to +5 dBm and has a receiver sensitivity of −21 dBm @ 2.125 Gb/s; −22 dBm @ 1.25/1.06 Gb/s. Maximum receiver input is 0 dBm.
Does the FTLF1519P1WNL support DDM / digital diagnostics?
Yes. Digital diagnostics over the SFP MSA 2-wire serial bus (temp, bias, optical power, voltage, alarms). Your switch can read live temperature, voltage, laser bias and Tx/Rx power.
Which fiber and connector does the FTLF1519P1WNL use?
The FTLF1519P1WNL works at 1550nm DFB over SMF. Both ends of a link must use the same optical standard.
Will the FTLF1519P1WNL work in my Cisco, Juniper, Arista or HPE switch?
The FTLF1519P1WNL 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.
FTLF1519P1WNL vs FTLF1519P1BCL: what is the difference?
Both are in Finisar's FTLF1519P1 family. They differ in temperature grade (extended vs commercial). Pick the variant that matches your temperature, latch and wavelength needs.
What temperature range is the FTLF1519P1WNL rated for?
The FTLF1519P1WNL is an extended-temperature part. Choose an industrial (T) variant for outdoor or uncontrolled sites.
What does the FTLF1519P1WNL part number mean?
The FTLF prefix marks Finisar's SFP / SFP28 / SFP56 family (incl. Fibre Channel). The E letter in the suffix usually marks the extended temperature grade. The remaining characters identify the optical design and build variant.
Is the FTLF1519P1WNL still available?
The FTLF1519P1WNL 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 FTLF1519P1WNL price in India and how do I order?
The Finisar FTLF1519P1WNL 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 FTLF1519P1WNL need?
It runs from 3.15–3.60 V with power dissipation of < 700 mW typ (200 typ / 300 max mA).
