Passive connectivity optical module
A passive connectivity optical module (“PassCOM”) is disclosed. A PassCOM is a passive device without a switching functionality. A PassCOM connects links between a plurality of nodes using replaceable plugs. The device can be used for an internal inter-node switching system, where each node is capable of sending data to a destination using a specific link. A source node sends data through a particular link that is connected to a link from a destination node in the PassCOM. Data is first sent from a source node through a link connecting the source node and the PassCOM, then the data is transmitted, through a plug, to the destination node using a link connecting the PassCOM and the destination.
1. A passive network switching apparatus comprising:
a plurality of front-end connectors for coupling to a plurality of network elements;
at least one replaceable plug;
at least one back-end connector for receiving the at least one replaceable plug; and
a plurality of links passively coupling the plurality of front-end connectors to the at least one back-end connector;
wherein the at least one replaceable plug is configured to couple the plurality of network elements in full mesh such that each pair of network elements includes a direct passive link directly connecting that pair without any intervening switching or routing.
