Abstract
The test-bed for multi-wavelength passive optical (POR) network requires many
independent signal sources as high-speed programmable networking testing platform.
Although commercial high-speed equipment is available, those equipments are typically
very expensive. The focus of this project is to build a networking test-bed is the design
and implement of the high-speed programmable networking testing platform. In the
continuation of this project, the testing platform will evolve to a networking node capable
to process 10-Gb/s Ethernet traffic. Currently, the testing platform is programmed in
Verilog and verified in a FPGA test broad. The FPGA is combined a Mux and DeMux
circuits. The FPGA for pattern generator and error counting can be re-programmed for
data processing
In additional to the testing platform, low-cost high-dispersion-tolerance 10-Gb/s
transceiver is also implemented. Based on directly-modulated of a simple distributedfeedback
laser with a narrow-band optical filtering, the signal can be transmitted for a
distance of 60-km with dispersion compensation as compared with a distance of only 20
km in conventional scheme. The low-cost transceiver can greatly lower the cost for POR
with small diameter without the requirement of costly externally modulated transceiver.
