About the Finisar FTR-1631-18
The Finisar FTR-1631-18 (now a Coherent Corp. product, formerly II-VI) is a GBIC DWDM GBIC optical transceiver for up to 2.67 Gb/s links at 1563.05nm (191.8THz, ITU ch18) over SMF. It belongs to Finisar's FTR-1631 DWDM GBIC family, which has 45 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.
- Up to 2.7 Gb/s bi-directional data links
- Temperature-stabilized DWDM-rated DFB laser transmitter
- 100 GHz ITU Grid, C Band
- Wavelength controlled within ±0.1 nm over life and temperature
- Extended link budget with APD receiver technology
- OC-48 LR-2 compliant
FTR-1631-18: frequently asked questions
What is the Finisar FTR-1631-18?
The FTR-1631-18 is a Finisar GBIC transceiver for DWDM GBIC 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-1631-18?
Share your link length and fibre type and we will confirm the reach of the FTR-1631-18 from the Finisar datasheet before you order.
What is the optical power budget of the FTR-1631-18?
Per the Finisar family datasheet, the FTR-1631-18 transmits 0 to +4 dBm and has a receiver sensitivity of −27 dBm @ BER<10⁻¹² (−29 dBm @ BER<10⁻⁹). Maximum receiver input is −6 dBm max input; damage threshold +6 dBm.
Which fiber and connector does the FTR-1631-18 use?
The FTR-1631-18 works at 1563.05nm (191.8THz, ITU ch18) 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-1631-18 work in my Cisco, Juniper, Arista or HPE switch?
The FTR-1631-18 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-1631-18 vs FTR-1631-17: what is the difference?
Both are in Finisar's FTR-1631 DWDM GBIC family. They differ in wavelength (1563.05nm (191.8THz, ITU ch18) vs 1563.86nm (191.7THz, ITU ch17)). Pick the variant that matches your temperature, latch and wavelength needs.
What does the FTR-1631-18 part number mean?
The FTR- prefix marks Finisar's GBIC family. The remaining characters identify the optical design and build variant.
Is the FTR-1631-18 still available?
The FTR-1631-18 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-1631-18 price in India and how do I order?
The Finisar FTR-1631-18 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-1631-18 need?
It runs from 5 V (4.75–5.25 V) with power dissipation of Supply current 250–400 mA (as printed).
