Suppose the following two optical signals are launched simultaneously into the fiber: an optical power of 150 µW at 1300 nm and an optical power of 100 µW at 1550 nm.
WebSOA, some of the 1310 nm data signal is also present at the 1550 nm output. These unwanted reflections may reduce available gain and therefore reduce the refractive index changes. The 1550 nm signal experiences high attenuation in the 1310 nm SOA. We measured the SOA attenuation at 1550 nm to be 13 dB at 0 mA SOA current and 20 dB at … Webpropagation, and therefore the measured attenuation was averaged over the modes and average attenuation measured using both methods. The lowest average attenuation at 1550 nm observed using the cutback method was 0.158 dB/ km, which is much lower than those of previously reported MCFs (0.177 dB/km in C-MCF,(11) 0.168 dB/km in uncou-
