Category 6 Cabling System City of Sunny Isles Beach <br />Request for Proposal Confidential and Proprietary <br />9 SYSTEM DESIGN REQUIREMENTS <br />9.1 HORIZONTAL CABLING <br />The Horizontal Subsystem is the portion of the telecommunications cabling system that extends from <br />the work area telecommunications outlet/connector to the horizontal cross - connect in the <br />telecommunications room. It consists of the telecommunications outlet/connector, the horizontal <br />cables, optional consolidation point, and that portion of the cross - connect in the telecommunications <br />room serving the horizontal cable. <br />9.2 BACKBONE CABLING <br />9.2.1 INTRABUILDING CABLING <br />All cable will be installed via a conduit system that will be in place prior to start of project. This system <br />will be used to connect the main equipment/computer (MDF) room to the (IDF) closets. Data <br />Backbone will consist of Multimode Fiber optic cabling, 12- strand 62.5/125um & 6- strand 9/125um <br />Single Mode fiber optic, manufactured by Commscope or approved equal. Voice riser shall consist of <br />100 or 50 pair category 5e. <br />9.2.2 INTERBUILDING CABLING <br />When a distribution system encompasses more than one building, the components that provide the <br />link between buildings constitute the Interbuilding Backbone Subsystem. This subsystem includes the <br />backbone transmission media, associated connecting hardware terminating this media, and electrical <br />protection devices to mitigate harmful voltages when the media is exposed to lightning and /or high <br />voltage power surges that pass through the building cable. It is normally a first -level backbone cable <br />beginning at the main cross - connect in the equipment room of the hub building and extending to the <br />intermediate cross - connect in the equipment room of a satellite building. <br />
