FWLF163252: frequently asked questions
What is the Finisar FWLF163252?
The FWLF163252 is a Finisar SFP transceiver for DWDM OC-48/STM-16 (2.7G), 100GHz C-band 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 FWLF163252?
The FWLF163252 is specified for up to 120km 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 FWLF163252?
Per the Finisar family datasheet, the FWLF163252 transmits 0 to +4 dBm and has a receiver sensitivity of −28 dBm (BER<10⁻¹²). Maximum receiver input is −9 dBm; damage threshold +6 dBm.
Does the FWLF163252 support DDM / digital diagnostics?
Yes. 2-wire serial digital diagnostics. Your switch can read live temperature, voltage, laser bias and Tx/Rx power.
Which fiber and connector does the FWLF163252 use?
The FWLF163252 works at 1535.82nm (195.2THz, ITU ch52) 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 FWLF163252 work in my Cisco, Juniper, Arista or HPE switch?
The FWLF163252 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.
FWLF163252 vs FWLF163217: what is the difference?
Both are in Finisar's FWLF1632 family. They differ in wavelength (1535.82nm (195.2THz, ITU ch52) vs 1563.86nm (191.7THz, ITU ch17)). Pick the variant that matches your temperature, latch and wavelength needs.
What temperature range is the FWLF163252 rated for?
The FWLF163252 is a commercial-temperature part rated −5 to 70 °C. Choose an industrial (T) variant for outdoor or uncontrolled sites.
What does the FWLF163252 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 FWLF163252 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 FWLF163252 price in India and how do I order?
The Finisar FWLF163252 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 FWLF163252 need?
It runs from 3.3 V (3.13–3.50 V) with power dissipation of 1.3 W max (Icc 380 mA).
