FTLF1319F1HTL: frequently asked questions
What is the Finisar FTLF1319F1HTL?
The FTLF1319F1HTL is a Finisar SFF 2x5 transceiver for 2G/1G FC LW + GbE LX (2.125G) at up to 2.125 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 is the maximum distance of the FTLF1319F1HTL?
The FTLF1319F1HTL 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 FTLF1319F1HTL?
Per the Finisar family datasheet, the FTLF1319F1HTL transmits −9.5 to −3 dBm and has a receiver sensitivity of −22 dBm @ 1.0625/1.25 Gb/s; −21 dBm @ 2.125 Gb/s. Maximum receiver input is 0 dBm.
Which fiber and connector does the FTLF1319F1HTL use?
The FTLF1319F1HTL works at 1310nm over SMF. Both ends of a link must use the same optical standard.
Will the FTLF1319F1HTL work in my Cisco, Juniper, Arista or HPE switch?
The FTLF1319F1HTL follows the SFF 2x5 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.
FTLF1319F1HTL vs FTLF1319F1GTL: what is the difference?
Both are in Finisar's FTLF1319F1 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 FTLF1319F1HTL rated for?
The FTLF1319F1HTL is an industrial-temperature part rated −40 to 85 °C. Industrial grade suits outdoor cabinets, telecom huts and plant floors.
What does the FTLF1319F1HTL 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 FTLF1319F1HTL 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 FTLF1319F1HTL price in India and how do I order?
The Finisar FTLF1319F1HTL 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 FTLF1319F1HTL need?
It runs from 3.3 V (3.0–3.6 V) with power dissipation of < 700 mW (300 mA).
