10 ns high-speed PLZT optical content distribution system having slot-switcn and GMPLS controller

Abstract

We have developed the high-speed PLZT ((Pb,La)(Zr,Ti) O3) optical content distribution system having slot-switch and GMPLS controller in the 1×8 distribution switch. The switching speed of our developed system is less than 10 nsec and the world fastest switching time in the optical switch with more than 8 outputs. The system can switch transparent time slot whose size can range from 10 nsec to 1 sec. Each slot is reserved very quickly by an extended Resource reSerVation Protocol (RSVP) message that is now being standardized for the GMPLS control plane. According to calculations, the proposed system can handle more than 500 users with minimum receiving power of -18dBm, which is about an 8 fold improvement over Passive Optical Network (PON). We consider that the system well supports content distribution in the access network. © IEICE 2008.
