Claims Analysis
Total Claims: 21
Claim 1
Independent Claim
100 words
A fiber optic communications network for internal building data transmission having at least three data work station terminals which can communicate with each other but are not serially connected comprising: (a) at least three junction boxes each of which is connected to at least one work station terminal through no more than two fibers; (b) at least two floor distribution terminals to which at least two of said junction boxes are connected by fiber optic cable to different floor distribution terminals; and (c) nonadhesive connector and jumper cable means for changing the pattern of the network at said distribution terminals.
Claim 2
Dependent Claim
100 words
A fiber optic communications network for internal building data transmission having at least three data work station terminals which can communicate with each other but are not serially connected comprising: (a) at least three junction boxes each of which is connected to at least one work station terminal through no more than two fibers; (b) at least two floor distribution terminals to which at least two of said junction boxes are connected by fiber optic cable to different floor distribution terminals; and (c) nonadhesive connector and jumper cable means for changing the pattern of the network at said distribution terminals.
