FTLF1421P1BTL-3G: frequently asked questions
What is the Finisar FTLF1421P1BTL-3G?
The FTLF1421P1BTL-3G is a Finisar SFP transceiver for CPRI 3G wireless (3.07G) / OC-48 IR-1 at up to 2.67 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 FTLF1421P1BTL-3G?
The FTLF1421P1BTL-3G 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 FTLF1421P1BTL-3G?
Per the Finisar family datasheet, the FTLF1421P1BTL-3G transmits −5 to 0 dBm and has a receiver sensitivity of −18 dBm @ 3.07 Gb/s.
Does the FTLF1421P1BTL-3G 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 FTLF1421P1BTL-3G use?
The FTLF1421P1BTL-3G works at 1310nm over SMF. Both ends of a link must use the same optical standard.
Will the FTLF1421P1BTL-3G work in my Cisco, Juniper, Arista or HPE switch?
The FTLF1421P1BTL-3G 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.
What temperature range is the FTLF1421P1BTL-3G rated for?
The FTLF1421P1BTL-3G is an industrial-temperature part rated −40 to 85 °C. Industrial grade suits outdoor cabinets, telecom huts and plant floors.
What does the FTLF1421P1BTL-3G 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 FTLF1421P1BTL-3G 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 FTLF1421P1BTL-3G price in India and how do I order?
The Finisar FTLF1421P1BTL-3G 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 FTLF1421P1BTL-3G need?
It runs from 3.3 V (3.00–3.60 V) with power dissipation of <700 mW typical (Icc 200 typ / 300 mA max).
