200-km 10-Gbit/s NRZ repeaterless transmission over SSMF with fiber grating
2004
In this paper, a low-cost repeaterless transmission system is demonstrated at 10Gbit/s using two Sampled Chirped fiber Bragg gratings (SCBG) to realize the dispersion compensation of 210km transmission over G.652 single-mode fiber (SSMF). The two SCBGs are used as dispersion management components to mitigate the damage caused by the pulse broadening effort before the receiver terminal. Non-return-to-zero (NRZ) modulation format is adopted and EDFAs as boost amplifier and pre-amplifiers in this system. Low-gain Raman amplifier is used to improve the signal noise ratio (SNR) at the end of the transmission fiber.
