About the Finisar FTLF1419P1WCL
The Finisar FTLF1419P1WCL (now a Coherent Corp. product, formerly II-VI) is a SFP 1000BASE-EX / 2G-1G FC (2.125G) optical transceiver for up to 2.125 Gb/s links at 1310nm DFB over SMF, with reach up to 55km. It is a commercial-temperature part rated −10 to 70 °C. It belongs to Finisar's FTLF1419P1 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: Gigabit Ethernet, 1/2/4G Fibre Channel SAN, SONET OC-48 / STM-16 and CWDM/DWDM metro links.
- Up to 2.125 Gb/s bi-directional data links
- Hot-pluggable SFP footprint
- Built-in digital diagnostic functions
- Uncooled 1310 nm DFB laser transmitter
- Metal enclosure, for lower EMI
- No rate select needed
FTLF1419P1WCL: frequently asked questions
What is the Finisar FTLF1419P1WCL?
The FTLF1419P1WCL is a Finisar SFP transceiver for 1000BASE-EX / 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 FTLF1419P1WCL?
The FTLF1419P1WCL is specified for up to 55km 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 FTLF1419P1WCL?
Per the Finisar family datasheet, the FTLF1419P1WCL transmits 0 to +5 dBm and has a receiver sensitivity of −21 dBm @ 2.125 Gb/s; −22 dBm @ 1.25/1.06 Gb/s. Maximum receiver input is 0 dBm.
Does the FTLF1419P1WCL support DDM / digital diagnostics?
Yes. Digital diagnostics over 2-wire serial (A2h). Your switch can read live temperature, voltage, laser bias and Tx/Rx power.
Which fiber and connector does the FTLF1419P1WCL use?
The FTLF1419P1WCL works at 1310nm DFB over SMF. Both ends of a link must use the same optical standard.
Will the FTLF1419P1WCL work in my Cisco, Juniper, Arista or HPE switch?
The FTLF1419P1WCL 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.
FTLF1419P1WCL vs FTLF1419P1BCL: what is the difference?
Both are in Finisar's FTLF1419P1 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 FTLF1419P1WCL rated for?
The FTLF1419P1WCL is a commercial-temperature part rated −10 to 70 °C. Choose an industrial (T) variant for outdoor or uncontrolled sites.
What does the FTLF1419P1WCL 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 the FTLF1419P1WCL still available?
The FTLF1419P1WCL 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 FTLF1419P1WCL price in India and how do I order?
The Finisar FTLF1419P1WCL 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 FTLF1419P1WCL need?
It runs from 3.3 V (3.0–3.6 V) with power dissipation of < 700 mW (200 typ / 300 max mA).
