Optical Space Switch Technologies Optical space switches are a key component ofanyburst switch architecture that maintains the data in optical format throughout =-=[5]-=-. There are two principal options for optical space switching. One is based on lithium niobate electro-optic directional couplers. This is fairly mature technology and switches as large as 8 8have bee...

...utputs. For a burst with fanout f, we estimate that the time to perform the setup will increase by (f ; 1)=4 times the ATM switch's basic cell processing time (about 130 ns in the system of reference =-=[12]-=-). Thus, the added latency for a connection with fanout 16 is under 2 s. The blocking performance for this simple multicast burst setup strategy is strongly dependent on the average load on the extern...
