34、cification 1 Scope This part of IEC 60876 applies to fibre optic switches possessing all of the following general features: they are passive in that they contain no optoelectronic or other transducing elements; they have one or more ports for the transmission of optical power and two or more states
35、in which power may be routed or blocked between these ports; the ports are optical fibres or fibre optic connectors. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application.

47、es: “Strict-sense non-blocking” refers to a switch matrix in which it is always possible to establish a connection between any free input port and any free output port, irrespective of previously established connections. “Wide-sense non-blocking” refers to a matrix in which it is always possible to
48、establish a desired connection provided that some systematic procedure is followed in setting up connections. Some multistage switching architectures fall into this category. “Rearrangeably non-blocking” refers to a switch matrix in which any free input port can be connected to any free output port
49、provided that other established connections are unconnected and then reconnected as part of making the new connection. 3.1.9normally on condition where a port pair is in a conducting state when there is no actuation energy applied for a non-latching switch 3.1.10normally off condition where a port pair is in an isolated state when there is no actuation energy applied for a non-latching switch 3.2
