About the Finisar FTR-1621-59
The Finisar FTR-1621-59 (now a Coherent Corp. product, formerly II-VI) is a GBIC CWDM multi-rate (to 2.67G), APD rx (non-RoHS) optical transceiver for up to 2.67 Gb/s links at CWDM 1591nm over SMF. It belongs to Finisar's FTR-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.
- All Metro data protocols from 125 Mb/s to 2.7 Gb/s
- Extended link budget of 30 dB with APD receiver technology
- Uncooled CWDM-rated DFB laser transmitter
- Standard GBIC footprint
- Very low jitter
- Metal enclosure for lower EMI
FTR-1621-59: frequently asked questions
What is the Finisar FTR-1621-59?
The FTR-1621-59 is a Finisar GBIC transceiver for CWDM multi-rate (to 2.67G), APD rx (non-RoHS) 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 FTR-1621-59?
Share your link length and fibre type and we will confirm the reach of the FTR-1621-59 from the Finisar datasheet before you order.
What is the optical power budget of the FTR-1621-59?
Per the Finisar family datasheet, the FTR-1621-59 transmits +1.0 to +5 dBm (typ +3.0) and has a receiver sensitivity of −27.0 dBm @2.5 Gb/s, BER<10⁻¹² (−28.0 dBm @ BER<10⁻⁹). Maximum receiver input is −7 dBm (max input power).
Which fiber and connector does the FTR-1621-59 use?
The FTR-1621-59 works at CWDM 1591nm 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 FTR-1621-59 work in my Cisco, Juniper, Arista or HPE switch?
The FTR-1621-59 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.
FTR-1621-59 vs FTR-1621-47: what is the difference?
Both are in Finisar's FTR-1621 CWDM GBIC family. They differ in wavelength (CWDM 1591nm vs CWDM 1471nm). Pick the variant that matches your temperature, latch and wavelength needs.
What does the FTR-1621-59 part number mean?
The FTR- prefix marks Finisar's GBIC family. The remaining characters identify the optical design and build variant.
Is the FTR-1621-59 still available?
The FTR-1621-59 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 FTR-1621-59 price in India and how do I order?
The Finisar FTR-1621-59 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 FTR-1621-59 need?
It runs from 5 V (4.75–5.25 V) with power dissipation of Supply current 280–350 mA (as printed).
