About the Finisar FTLF1217P2WTL
The Finisar FTLF1217P2WTL (now a Coherent Corp. product, formerly II-VI) is a SFP 100BASE-FX / OC-3 MM / ESCON optical transceiver for 155 Mb/s links at 1310nm LED over MMF, with reach up to 2km. It is an industrial-temperature part rated −40 to 85 °C. It belongs to Finisar's FTLF1217P2 family, which has 2 orderable variants that differ by temperature grade, latch, receiver build or wavelength channel. Typical uses: Fast/Gigabit Ethernet, SONET/SDH OC-3/OC-12, campus and access links, and legacy network upgrades.
- Fast Ethernet long-wavelength SFP (1310 nm LED)
- Hot-pluggable SFP footprint
- Built-in digital diagnostic functions
- Metal enclosure, for lower EMI
- Single 3.3 V power supply
- Low power dissipation
FTLF1217P2WTL: frequently asked questions
What is the Finisar FTLF1217P2WTL?
The FTLF1217P2WTL is a Finisar SFP transceiver for 100BASE-FX / OC-3 MM / ESCON at 155 Mb/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 FTLF1217P2WTL?
The FTLF1217P2WTL is specified for up to 2km 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 FTLF1217P2WTL?
Per the Finisar family datasheet, the FTLF1217P2WTL transmits −20 to −15 dBm and has a receiver sensitivity of −31 dBm @ 125 Mb/s; −30 dBm @ 51.8/155 Mb/s; −29 dBm @ 200 Mb/s. Maximum receiver input is −14 dBm (printed as '-14 mW' in the extracted text).
Does the FTLF1217P2WTL support DDM / digital diagnostics?
Yes. Digital diagnostics per SFP MSA over 2-wire serial (temp, voltage, bias, optical power). Your switch can read live temperature, voltage, laser bias and Tx/Rx power.
Which fiber and connector does the FTLF1217P2WTL use?
The FTLF1217P2WTL works at 1310nm LED over MMF. Both ends of a link must use the same optical standard.
Will the FTLF1217P2WTL work in my Cisco, Juniper, Arista or HPE switch?
The FTLF1217P2WTL 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.
FTLF1217P2WTL vs FTLF1217P2BTL: what is the difference?
Both are in Finisar's FTLF1217P2 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 FTLF1217P2WTL rated for?
The FTLF1217P2WTL is an industrial-temperature part rated −40 to 85 °C. Industrial grade suits outdoor cabinets, telecom huts and plant floors.
What does the FTLF1217P2WTL 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 FTLF1217P2WTL 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 FTLF1217P2WTL price in India and how do I order?
The Finisar FTLF1217P2WTL 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 FTLF1217P2WTL need?
It runs from 3.3 V (3.0–3.6 V) with power dissipation of 300 mA max supply current.
