FTLF8524P2xNL: frequently asked questions
What is the Finisar FTLF8524P2xNL?
The FTLF8524P2xNL 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 does the 'x' in FTLF8524P2xNL mean?
FTLF8524P2xNL is Finisar's family / ordering name. The 'x' is replaced by a code to make the exact orderable part number. For this family the codes are: B, W. See the variants table and tell us which one you need, or share your switch and link details and we will pick the right one.
What is the optical power budget of the FTLF8524P2xNL?
Per the Finisar family datasheet, the FTLF8524P2xNL 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 FTLF8524P2xNL 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 part numbers are in the FTLF8524P2xNL family?
Orderable variants include: FTLF8524P2BNL, FTLF8524P2WNL. Next Gen Networks supplies the exact variant you need in bulk with a GST invoice.
What is the maximum distance of the FTLF8524P2xNL?
The FTLF8524P2xNL 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.
Which fiber and connector does the FTLF8524P2xNL use?
The FTLF8524P2xNL works at 850nm over MMF. Both ends of a link must use the same optical standard.
Will the FTLF8524P2xNL work in my Cisco, Juniper, Arista or HPE switch?
The FTLF8524P2xNL 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.
What temperature range is the FTLF8524P2xNL rated for?
The FTLF8524P2xNL 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 FTLF8524P2xNL 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 your FTLF8524P2xNL genuine Finisar?
Yes. Next Gen Networks supplies original Finisar / Coherent modules, not third-party lookalikes or grey-market stock, and shares serial numbers on request.
What is the FTLF8524P2xNL price in India and how do I order?
The Finisar FTLF8524P2xNL 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 FTLF8524P2xNL need?
It runs from 3.3 V (3.0–3.6 V) with power dissipation of Supply current 180 typ / 240 max mA.
