FWLF16217D55: frequently asked questions
What is the Finisar FWLF16217D55?
The FWLF16217D55 is a Finisar SFP transceiver for CWDM multi-rate OC-48/STM-16, GbE, FC (to 2.67G), APD rx 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 FWLF16217D55?
The FWLF16217D55 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.
What is the optical power budget of the FWLF16217D55?
Per the Finisar family datasheet, the FWLF16217D55 transmits 0 to +5 dBm and has a receiver sensitivity of −28 dBm (BER<10⁻¹²). Maximum receiver input is −9 dBm.
Does the FWLF16217D55 support DDM / digital diagnostics?
Yes. Built-in digital diagnostics, 2-wire serial (AT24C01A 128-byte EEPROM). Your switch can read live temperature, voltage, laser bias and Tx/Rx power.
Which fiber and connector does the FWLF16217D55 use?
The FWLF16217D55 works at CWDM 1551nm 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 FWLF16217D55 work in my Cisco, Juniper, Arista or HPE switch?
The FWLF16217D55 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.
FWLF16217D55 vs FWLF16217D47: what is the difference?
Both are in Finisar's FWLF16217D family. They differ in wavelength (CWDM 1551nm vs CWDM 1471nm). Pick the variant that matches your temperature, latch and wavelength needs.
What temperature range is the FWLF16217D55 rated for?
The FWLF16217D55 is a commercial-temperature part rated 0 to 70 °C. Choose an industrial (T) variant for outdoor or uncontrolled sites.
What does the FWLF16217D55 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 FWLF16217D55 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 FWLF16217D55 price in India and how do I order?
The Finisar FWLF16217D55 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 FWLF16217D55 need?
It runs from 3.3 V (3.15–3.60 V) with power dissipation of Supply current 210 typ / 300 max mA.
