Copper design is fairly straight forward, as it is limited to the 100m channel, has a standard connector type, will predominantly be used in the horizontal, is likely only to be of one performance specification, and supports a single network type. Namely, Ethernet. Fiber design can be more complex as there are legacy connectors and interfaces, multiple performance demands, used from the EDA to HDA to MDA and Entrance and multiple networks. The design process phases should include: A. Calculate fiber requirements per cabinet. Also allowing for growth and redundancy. B. Determine the cable routes from each cabinet to each cabinet and each area to each area, including EDA to HDA, HDA to MDA, and MDA to Primary Entrance. In addition, consider any secondary or tie cable routes. Wiring standards limit the distance between the main cross-connect and closet. Distances may impact your choice of glass and application interface. C. Determine interconnect and cross-connect at each termination point, and any required splicing points. D. Determine the supporting structures required for additional lateral cable runs. Each of these key phases will require additional design considerations that we will now cover.

TIA/EIA942 notes that the horizontal media distance shall be a maximum of 90m link and 100m channel, independent of media type. See item (2) above. The maximum cabling distance in a Data Center not containing an HDA shall be 300m, including cords, for fiber. But, copper
