FTLF1318P3BTL: frequently asked questions
What is the Finisar FTLF1318P3BTL?
The FTLF1318P3BTL is a Finisar SFP transceiver for 1000BASE-LX / 1GFC at 1 Gb/s. Finisar is now part of Coherent Corp. (formerly II-VI), and the part number is unchanged. It is used for Fast/Gigabit Ethernet, SONET/SDH OC-3/OC-12, campus and access links, and legacy network upgrades.
What is the maximum distance of the FTLF1318P3BTL?
The FTLF1318P3BTL is specified for up to 10km 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 FTLF1318P3BTL?
Per the Finisar family datasheet, the FTLF1318P3BTL transmits −9.5 to −3 dBm and has a receiver sensitivity of −19 dBm @ 1.25 Gb/s; −21 dBm @ 1.0625 Gb/s. Maximum receiver input is 0 dBm.
Does the FTLF1318P3BTL support DDM / digital diagnostics?
Yes. Internally calibrated digital diagnostics over 2-wire serial (temp, voltage, bias, Tx/Rx power). Your switch can read live temperature, voltage, laser bias and Tx/Rx power.
Which fiber and connector does the FTLF1318P3BTL use?
The FTLF1318P3BTL works at 1310nm over SMF. Both ends of a link must use the same optical standard.
Will the FTLF1318P3BTL work in my Cisco, Juniper, Arista or HPE switch?
The FTLF1318P3BTL 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 FTLF1318P3BTL rated for?
The FTLF1318P3BTL is an industrial-temperature part rated −40 to 85 °C. Industrial grade suits outdoor cabinets, telecom huts and plant floors.
What does the FTLF1318P3BTL part number mean?
The FTLF prefix marks Finisar's SFP / SFP28 / SFP56 family (incl. Fibre Channel). The I letter in the suffix usually marks the industrial temperature grade. The remaining characters identify the optical design and build variant.
Is your FTLF1318P3BTL 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 FTLF1318P3BTL price in India and how do I order?
The Finisar FTLF1318P3BTL 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 FTLF1318P3BTL need?
It runs from 3.3 V (3.0–3.6 V) with power dissipation of < 600 mW typ (300 mA max).
