Optical networks may be deployed within hospitals and other structures for permitting bi-directional optical communication. The networks include couplers that permit the network to branch out into multiple sub-networks and hubs. Each of these couplers functions as a junction box and can be used to couple with other networks, such as the Internet or other third party service providers, and can also be used to branch off signals off o main backbone. Furthermore, these couplers may be used to couple signals off of the backbone or a subnetwork toward a specific individual unit. The networks include bi-directional optical amplifiers which compensate for losses associated with the various couplers dispersed throughout the network.
