FTLF1619P1BCL: frequently asked questions
What is the Finisar FTLF1619P1BCL?
The FTLF1619P1BCL is a Finisar SFP transceiver for 1000BASE-EZX / 2G-1G FC (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 FTLF1619P1BCL?
The FTLF1619P1BCL is specified for up to 110-115km 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 FTLF1619P1BCL?
Per the Finisar family datasheet, the FTLF1619P1BCL transmits 0 to +5 dBm and has a receiver sensitivity of −28 dBm @ 2.125 Gb/s; −30 dBm @ 1.25/1.0625 Gb/s. Maximum receiver input is −9 dBm.
Does the FTLF1619P1BCL support DDM / digital diagnostics?
Yes. Built-in digital diagnostics over 2-wire serial. Your switch can read live temperature, voltage, laser bias and Tx/Rx power.
Which fiber and connector does the FTLF1619P1BCL use?
The FTLF1619P1BCL works at 1550nm DFB + APD over SMF. Both ends of a link must use the same optical standard.
Will the FTLF1619P1BCL work in my Cisco, Juniper, Arista or HPE switch?
The FTLF1619P1BCL 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.
FTLF1619P1BCL vs FTLF1619P1WCL: what is the difference?
Both are in Finisar's FTLF1619P1 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 FTLF1619P1BCL rated for?
The FTLF1619P1BCL is a commercial-temperature part rated −10 to 70 °C. Choose an industrial (T) variant for outdoor or uncontrolled sites.
What does the FTLF1619P1BCL part number mean?
The FTLF prefix marks Finisar's SFP / SFP28 / SFP56 family (incl. Fibre Channel). The C letter in the suffix usually marks the commercial temperature grade. The remaining characters identify the optical design and build variant.
Is your FTLF1619P1BCL 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 FTLF1619P1BCL price in India and how do I order?
The Finisar FTLF1619P1BCL 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 FTLF1619P1BCL need?
It runs from 3.3 V (3.0–3.6 V) with power dissipation of < 700 mW typ (230 typ / 300 max mA).
