About the Finisar FTLF1322P1WTR
The Finisar FTLF1322P1WTR (now a Coherent Corp. product, formerly II-VI) is a SFP OC-12 IR-1, STM S-4.1 (622M) optical transceiver for 622 Mb/s links at 1310nm FP over SMF, with reach up to 15km. It is an industrial-temperature part rated −40 to 85 °C. It belongs to Finisar's FTLF1322P1 family, which has 2 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: Fast/Gigabit Ethernet, SONET/SDH OC-3/OC-12, campus and access links, and legacy network upgrades.

FTLF1322P1WTR: frequently asked questions
What is the Finisar FTLF1322P1WTR?
The FTLF1322P1WTR is a Finisar SFP transceiver for OC-12 IR-1, STM S-4.1 (622M) at 622 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 FTLF1322P1WTR?
The FTLF1322P1WTR is specified for up to 15km 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 FTLF1322P1WTR?
Per the Finisar family datasheet, the FTLF1322P1WTR transmits −15 to −8 dBm and has a receiver sensitivity of −28 dBm (OC-12 and OC-3). Maximum receiver input is −8 dBm.
Does the FTLF1322P1WTR support DDM / digital diagnostics?
Yes. Digital diagnostics via 2-wire serial interface per SFP MSA (temperature, laser bias, Tx/Rx power, voltage; alarm/warning flags). Your switch can read live temperature, voltage, laser bias and Tx/Rx power.
Which fiber and connector does the FTLF1322P1WTR use?
The FTLF1322P1WTR works at 1310nm FP over SMF. Both ends of a link must use the same optical standard.
Will the FTLF1322P1WTR work in my Cisco, Juniper, Arista or HPE switch?
The FTLF1322P1WTR 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.
FTLF1322P1WTR vs FTLF1322P1BTR: what is the difference?
Both are in Finisar's FTLF1322P1 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 FTLF1322P1WTR rated for?
The FTLF1322P1WTR is an industrial-temperature part rated −40 to 85 °C. Industrial grade suits outdoor cabinets, telecom huts and plant floors.
What does the FTLF1322P1WTR 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 the FTLF1322P1WTR still available?
The FTLF1322P1WTR 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 FTLF1322P1WTR price in India and how do I order?
The Finisar FTLF1322P1WTR 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 FTLF1322P1WTR need?
It runs from 3.3 V (3.10–3.50 V) with power dissipation of <700 mW typical (Icc 165 typ / 300 mA max).
