In this article we present methods of amplitude and phase (clock) recovery for burst mode fiber optic receivers. Using these methods it is possible to recover amplitude and clock phase using an 8 bit preamble, which contains two guard bits, a field of three `1s' for amplitude recovery, and a `0 1 0' sequence for clock recovery. The methods shown are application independent and can be used with bursts of varying length, thus will be applicable to a number of LAN and MAN systems, as well as telephony over passive optical networks. Experimental results are presented.© (1993) COPYRIGHT SPIE--The International Society for Optical Engineering. Downloading of the abstract is permitted for personal use only. |
