Fixed Fibre Interface (FFI)
The FFI is a special optical module designed to achieve exceptional span distances without in-line amplification. It is assembled on the PCB, is not pluggable and equipped with an LC connector which provides the same management information as XFPs. FFI interfaces can reach up to 300 km without the need of mid-span (in-line) amplification or regeneration (and only with the use of booster, pre-amps and Raman amplifiers). The FFI optical interface is available with 1550 nm, ITU recommended DWDM wavelengths and tunable optics. New tunable optics simplify deployments and lower requirements as well as cost for spare parts and support full C-band (80 channels) with 50 GHz channel spacing. The tunable FFI can be assembled/integrated on all MICROSENS modules supporting a 10G interface.
