FTLF1721P2BTL: frequently asked questions
What is the Finisar FTLF1721P2BTL?
The FTLF1721P2BTL is a Finisar SFP transceiver for OC-48 LR-1 / STM L-16.1 multirate (2.67G) 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 FTLF1721P2BTL?
The FTLF1721P2BTL is specified for up to 40km 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 FTLF1721P2BTL use?
The FTLF1721P2BTL works at 1310nm DFB + APD over SMF. Both ends of a link must use the same optical standard.
Does the FTLF1721P2BTL support DDM / digital diagnostics?
Yes. Built-in digital diagnostic functions. Your switch can read live temperature, voltage, laser bias and Tx/Rx power.
Will the FTLF1721P2BTL work in my Cisco, Juniper, Arista or HPE switch?
The FTLF1721P2BTL 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.
FTLF1721P2BTL vs FTLF1721P2BCL: what is the difference?
Both are in Finisar's FTLF1721P2 family. They differ in temperature grade (industrial vs commercial). Pick the variant that matches your temperature, latch and wavelength needs.
What temperature range is the FTLF1721P2BTL rated for?
The FTLF1721P2BTL is an industrial-temperature part rated −40 to 85 °C. Industrial grade suits outdoor cabinets, telecom huts and plant floors.
What does the FTLF1721P2BTL 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 FTLF1721P2BTL 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 FTLF1721P2BTL price in India and how do I order?
The Finisar FTLF1721P2BTL 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 FTLF1721P2BTL need?
It runs from 3.3 V with power dissipation of <700 mW typical.
