Technology Development and Networking Application of a Mobile Passive Optical Access Network System
There are various emergencies including disaster relief, military actions, anti-terrorist and peace maintaining operation or occasional real-time information transmission in poor geological environments. Aiming at these, a mobile emergency optical access network system is proposed to achieve the seamless connection between mobile and fixed communications. After integrating various emergency demands, system technology indices, optical line termination (OLT) and optical network unit (ONU) technology indices are formulated. For systematic design, a PAS5001-NM3 chip is applied at OLT while a PAS6201-NM3 chip, multi-function interface technology fusing various device interfaces of links and dynamic bandwidth allocation (DBA) control technology are employed at ONU end. The test results show that the throughputs from the initiator to the target are 75.47 (transmission control protocol (TCP)) and 20.56 Mbps (user datagram protocol (UDP)), respectively. At different geographical locations in different areas, multi-service fulfillment trials such as voice, data, image and video are carried out separately at the transmission distances of 8, 10 and 18 km. The technology indices of the system all meet the design requirements with a stable network operation and normal signal transmission.
