FTLF1323S2GTR: frequently asked questions
What is the Finisar FTLF1323S2GTR?
The FTLF1323S2GTR is a Finisar SFF 2x10 transceiver for OC-3 SR-1/IR-1 (155M) 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 FTLF1323S2GTR?
The FTLF1323S2GTR 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.
Which fiber and connector does the FTLF1323S2GTR use?
The FTLF1323S2GTR works at 1310nm FP over SMF. Both ends of a link must use the same optical standard.
Does the FTLF1323S2GTR support DDM / digital diagnostics?
Yes. Analog diagnostics (2x10 SFF pins). Your switch can read live temperature, voltage, laser bias and Tx/Rx power.
Will the FTLF1323S2GTR work in my Cisco, Juniper, Arista or HPE switch?
The FTLF1323S2GTR follows the SFF 2x10 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.
FTLF1323S2GTR vs FTLF1323S2HTR: what is the difference?
Both are in Finisar's FTLF1323S2 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 FTLF1323S2GTR rated for?
The FTLF1323S2GTR is an industrial-temperature part rated −40 to 85 °C. Industrial grade suits outdoor cabinets, telecom huts and plant floors.
What does the FTLF1323S2GTR 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 FTLF1323S2GTR 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 FTLF1323S2GTR price in India and how do I order?
The Finisar FTLF1323S2GTR 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 FTLF1323S2GTR need?
It runs from 3.3 V with power dissipation of <700 mW typical.
