FTLF1523P1xTL: frequently asked questions
What is the Finisar FTLF1523P1xTL?
The FTLF1523P1xTL is a Finisar SFP transceiver for OC-3 LR-2, STM L-1.2 (155M) at 155 Mb/s. Finisar is now part of Coherent Corp. (formerly II-VI), and the part number is unchanged. It is used for Fast/Gigabit Ethernet, SONET/SDH OC-3/OC-12, campus and access links, and legacy network upgrades.
What does the 'x' in FTLF1523P1xTL mean?
FTLF1523P1xTL is Finisar's family / ordering name. The 'x' is replaced by a code to make the exact orderable part number. For this family the codes are: B, W. See the variants table and tell us which one you need, or share your switch and link details and we will pick the right one.
What is the optical power budget of the FTLF1523P1xTL?
Per the Finisar family datasheet, the FTLF1523P1xTL transmits −5 to 0 dBm and has a receiver sensitivity of −34 dBm. Maximum receiver input is −10 dBm.
Does the FTLF1523P1xTL 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 part numbers are in the FTLF1523P1xTL family?
Orderable variants include: FTLF1523P1BTL, FTLF1523P1WTL. Next Gen Networks supplies the exact variant you need in bulk with a GST invoice.
What is the maximum distance of the FTLF1523P1xTL?
The FTLF1523P1xTL is specified for up to 80km 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 FTLF1523P1xTL use?
The FTLF1523P1xTL works at 1550nm DFB over SMF. Both ends of a link must use the same optical standard.
Will the FTLF1523P1xTL work in my Cisco, Juniper, Arista or HPE switch?
The FTLF1523P1xTL 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 FTLF1523P1xTL rated for?
The FTLF1523P1xTL is an industrial-temperature part rated −40 to 85 °C. Industrial grade suits outdoor cabinets, telecom huts and plant floors.
What does the FTLF1523P1xTL 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 FTLF1523P1xTL 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 FTLF1523P1xTL price in India and how do I order?
The Finisar FTLF1523P1xTL 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 FTLF1523P1xTL need?
It runs from 3.3 V (3.10–3.50 V) with power dissipation of <700 mW typical (Icc 300 mA max).
