Abstract

With the drastically growth in optical communication technology, a lossless, low-crosstalk and multifunction optical switch is most desirable for large-scale photonic network. To realize such a switch, we have introduced the new architecture of optical switch that embedded many functions on single device. The asymmetrical architecture of OXADM consists of 3 parts; selective port, add/drop operation, and path routing. The unique features offered by OXADM has extended its application to Fiber to-the Home Technology (FTTH), here the OXADM is used as a wavelength management element in Optical Line Terminal (OLT). Each port is assigned specifically with the operating wavelengths and with the dynamic routing management to ensure no traffic combustion occurs in OLT. Protection and restoration mechanisms have been applied in backbone networks, but access networks are not considered significantly in the scope of survivability. Towards that, this paper describes our recent approach toward advanced customer access network through the development of an access control system (ACS). The ACS focuses on providing survivability through the OXADM restoration scheme against failure by means of dedicated and shared protection that is applied in FTTH-EPON. A next feature is the high speed restoration achieved by automatic re-routing using fiber status monitoring. Each OXADM has a node controller which receives reports on the status periodically from access control system (ACS). When a failure is detected, The ACS will send a command to the related OXADM to be activated. The proposed restoration system is the first in its kind which covers the survivability in the drop section of FTTH access network.
