2. 6. Layered optical networks : implications to switching and transmission

   Author : Stefan Larsson; KTH; []
   Keywords : ;

   Abstract : With the aim of supporting and enhancing high-capacitycommunication networks, such as telephony, Internet and others,this work has investigated:· transmission gains withtime-slotted optical communication, · performance ofoptical add/drop multiplexers (OADMs) and optical crossconnects(OXCs), · OXC networks serving Internet Protocol(IP)-routers, · packet hop reductions in IP-controlledoptical networks, · a simple optical neighbour discoverymethod, · economics of complementing a client network withan optical express layer.Time-slotting was shown to enable bi-directionaltransmission at the same frequency and multiwavelengthtransmission over dispersion-shifted fibre.
