FWLF1524P2V51: frequently asked questions
What is the Finisar FWLF1524P2V51?
The FWLF1524P2V51 is a Finisar SFP transceiver for CWDM 4G/2G/1G FC + GbE (rate select) at up to 4.25 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 FWLF1524P2V51?
The FWLF1524P2V51 is specified for up to 30km @4G / 50km @1-2G 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 FWLF1524P2V51?
Per the Finisar family datasheet, the FWLF1524P2V51 transmits +1 to +5 dBm and has a receiver sensitivity of −16.5 dBm @4.25 Gb/s; −20.5 dBm @2.125 Gb/s; −22.0 dBm @1.0625 Gb/s; −22 dBm @1.25 Gb/s GbE. Maximum receiver input is 0 dBm.
Does the FWLF1524P2V51 support DDM / digital diagnostics?
Yes. Built-in digital diagnostics; A0h (AT24C01A EEPROM) and A2h monitoring. Your switch can read live temperature, voltage, laser bias and Tx/Rx power.
Which fiber and connector does the FWLF1524P2V51 use?
The FWLF1524P2V51 works at CWDM 1511nm over SMF. CWDM/DWDM optics must match the channel of your mux/demux port. Both ends of a link must use the same optical standard.
Will the FWLF1524P2V51 work in my Cisco, Juniper, Arista or HPE switch?
The FWLF1524P2V51 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.
FWLF1524P2V51 vs FWLF1524P2V47: what is the difference?
Both are in Finisar's FWLF1524P2V family. They differ in wavelength (CWDM 1511nm vs CWDM 1471nm). Pick the variant that matches your temperature, latch and wavelength needs.
What temperature range is the FWLF1524P2V51 rated for?
The FWLF1524P2V51 is a commercial-temperature part rated −5 to 75 °C. Choose an industrial (T) variant for outdoor or uncontrolled sites.
What does the FWLF1524P2V51 part number mean?
The FWLF prefix marks Finisar's CWDM / DWDM wavelength-specific SFP family. The C letter in the suffix usually marks the commercial temperature grade. The remaining characters identify the optical design and build variant.
Is your FWLF1524P2V51 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 FWLF1524P2V51 price in India and how do I order?
The Finisar FWLF1524P2V51 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 FWLF1524P2V51 need?
It runs from 3.3 V (3.1–3.5 V) with power dissipation of Supply current 300 mA max.
