Eye-Safe Data Transmission of 1.25 Gbit/S over 100-M Si-Pof Using Green Laser Diode
IEEE photonics technology letters(2012)
摘要
We report on 1.25-Gbit/s transmission over 100-m step-index polymer optical fiber (SI-POF) with 6.5-dB margin. Nonreturn-to-zero modulation with offline decision feedback equalization technique has been applied to an intensity modulated direct-detection optical channel. An edge emitting direct injection laser diode with 515 nm is used, which allows us to improve the system power budget due to a lower attenuation of the POF at this wavelength. The fiber-coupled optical power has been adjusted to 0 dBm which corresponds to eye-safety requirements.
