| Abstract: | Based on free space optical interconnection
technology, a broadband optical ATM switch system is introduced. Its line interface (LI) to SDH
networks can fulfill most functions of PL and ATM layer. A digital Phased Locked Loop (PLL)
controlled by a single chip microcomputer is designed to recover timing signal from SDH links
in order that the switch can receive and route data correctly. Being ideally suitable for building
reconfiguratable hardware system, Field Programmable Gate Array (FPGA) chips are used to
carry out the LI. Pipeline technique helps to handle timing problems in header processing FPGA
chip. |
