About the Finisar FTL-1621-55
The Finisar FTL-1621-55 (now a Coherent Corp. product, formerly II-VI) is a GBIC CWDM multi-rate (to 2.67G), APD rx optical transceiver for up to 2.67 Gb/s links at CWDM 1551nm over SMF. It belongs to Finisar's FTL-1621 CWDM GBIC family, which has 8 orderable variants that differ by temperature grade, latch, receiver build or wavelength channel. This is a legacy Finisar part; we help buyers find remaining stock or a current Coherent alternative. Typical uses: Gigabit Ethernet, 1/2/4G Fibre Channel SAN, SONET OC-48 / STM-16 and CWDM/DWDM metro links.

FTL-1621-55: frequently asked questions
What is the Finisar FTL-1621-55?
The FTL-1621-55 is a Finisar GBIC transceiver for CWDM multi-rate (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 FTL-1621-55?
Share your link length and fibre type and we will confirm the reach of the FTL-1621-55 from the Finisar datasheet before you order.
Which fiber and connector does the FTL-1621-55 use?
The FTL-1621-55 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 FTL-1621-55 work in my Cisco, Juniper, Arista or HPE switch?
The FTL-1621-55 follows the GBIC 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.
FTL-1621-55 vs FTL-1621-47: what is the difference?
Both are in Finisar's FTL-1621 CWDM GBIC family. They differ in wavelength (CWDM 1551nm vs CWDM 1471nm). Pick the variant that matches your temperature, latch and wavelength needs.
What does the FTL-1621-55 part number mean?
The FTL- prefix marks Finisar's GBIC family. The remaining characters identify the optical design and build variant.
Is the FTL-1621-55 still available?
The FTL-1621-55 is a legacy Finisar part, so new production is limited or ended. Next Gen Networks helps source remaining genuine stock and can suggest a current Coherent alternative with the same reach and wavelength.
What is the FTL-1621-55 price in India and how do I order?
The Finisar FTL-1621-55 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.
