This paper introduces the mid-span spectral inversion by four-wave mixing in a commercially available semiconductor optical amplifier (SOA) with a length of about 1.5 mm to optical label switching network based on combined frequency shift keying (FSK)-intensiy modulation (IM)/optical label-packet modulation to overcome the dispersion limitation of fiber.The 155 Mb/s-10 Gb/s combined FSK/IM signal is experimentally transmitted over a 100 km standard single mode fiber.10 10 and 10 9 BER (bit error ratio),or even better,is achieved for the FSK label and IM packet,respectively.The 19 dB power conversion efficiency is obtained for 1 nm wavelength detuning.
This paper introduces the mid-span spectral inversion by four-wave mixing in a commercially available semiconductor optical amplifier (SOA) with a length of about 1.5 mm to optical label switching network based on combined frequency shift keying (FSK) -intensiy modulation (IM ) / optical label-packet modulation to overcome the dispersion limitation of fiber. The 155 Mb / s-10 Gb / s combined FSK / IM signal was experimentally transmitted over a 100 km standard single mode fiber.10 10 and 10 9 BER error ratio), or even better, is achieved for the FSK label and IM packet, respectively. The 19 dB power conversion efficiency is obtained for 1 nm wavelength detuning.
