About the Finisar FTLF8524P2WNL
The Finisar FTLF8524P2WNL (now a Coherent Corp. product, formerly II-VI) is a SFP 4G/2G/1G FC optical transceiver for up to 4.25 Gb/s links at 850nm over MMF, with reach up to 150m (OM2 @4G) / up to 550m lower rates. It is an extended-temperature part rated −10 to 85 °C. It belongs to Finisar's FTLF8524P2 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 4.25 Gb/s bi-directional data links
- Hot-pluggable SFP footprint
- Built-in digital diagnostic functions
- Metal enclosure, for lower EMI
- Single 3.3 V power supply
- Extended operating temperature range: −20 °C to 85 °C
FTLF8524P2WNL: frequently asked questions
What is the Finisar FTLF8524P2WNL?
The FTLF8524P2WNL is a Finisar SFP transceiver for 4G/2G/1G FC at up to 4.25 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 FTLF8524P2WNL?
The FTLF8524P2WNL is specified for up to 150m (OM2 @4G) / up to 550m lower rates 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 FTLF8524P2WNL?
Per the Finisar family datasheet, the FTLF8524P2WNL transmits −9 to −2.5 dBm and has a receiver sensitivity of −20 dBm @ 1.0625/1.25 Gb/s; −18 dBm @ 2.125 Gb/s; −15 dBm @ 4.25 Gb/s. Maximum receiver input is 0 dBm.
Does the FTLF8524P2WNL support DDM / digital diagnostics?
Yes. Digital diagnostics per SFP MSA over 2-wire serial (temp, bias, Tx/Rx power, voltage, alarms/warnings). Your switch can read live temperature, voltage, laser bias and Tx/Rx power.
Which fiber and connector does the FTLF8524P2WNL use?
The FTLF8524P2WNL works at 850nm over MMF. Both ends of a link must use the same optical standard.
Will the FTLF8524P2WNL work in my Cisco, Juniper, Arista or HPE switch?
The FTLF8524P2WNL 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.
FTLF8524P2WNL vs FTLF8524P2BNV: what is the difference?
Both are in Finisar's FTLF8524P2 family. They differ in build / application (4G/2G/1G FC vs 4G/2G/1G FC + GbE (rate select)). Pick the variant that matches your temperature, latch and wavelength needs.
What temperature range is the FTLF8524P2WNL rated for?
The FTLF8524P2WNL is an extended-temperature part rated −10 to 85 °C (per Finisar's part-number temperature code). Choose an industrial (T) variant for outdoor or uncontrolled sites.
What does the FTLF8524P2WNL 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 FTLF8524P2WNL still available?
The FTLF8524P2WNL 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 FTLF8524P2WNL price in India and how do I order?
The Finisar FTLF8524P2WNL 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 FTLF8524P2WNL need?
It runs from 3.3 V (3.0–3.6 V) with power dissipation of Supply current 180 typ / 240 max mA.
