1.0 TELECOMMUNICATIONS CABLING INFRASTRUCTURE


1.1 OVERVIEW


The Telecommunications Cabling Infrastructure or Structured Cabling is designed to be a distributed star topology with all data, voice and video services originating from a Main Distribution Frame (MDF). From the MDF, cables shall extend to various Intermediate Distribution Frame (IDF) locations distributed throughout the campus. To the extent possible, all MDFs, IDFs shall be located in secured areas and/or enclosures; all such locations shall be subject to approval by OUSD technology and facilities departments. An extensive conduit system extends throughout most of the larger campuses and provides communication pathways to each of the buildings.

Connectivity between these facilities shall be via fiber optic and/or copper cables. For all new implementations, the following represents OUSD Standard:

  • 12-strand 9/125 microns, Single Mode ARMORED Plenum-rated Fiber Optic Riser Cables Indoor/Outdoor, Tight Buffer with SC-Duplex Connectors with ceramic ferrule, 9/125 microns. This is for connecting MDF to IDF.

  • Category 6a Unshielded Twisted Pair Copper Cables, with Category 6a RJ45 Connectors

  • B40-MB50 Multi-Band Antenna, The B40-MB50 Multi-Band Antenna shall be routed in a dedicated ½” minimum EMT conduit. The antenna shall be exterior wall mounted at roof level.

Alternate standards may be approved by OUSD on a case-by-case basis where existing cable will be supplemented by new cables.

Separate parallel systems exist only for the following: fire alarm, intrusion alarm, and building controls (e.g. BACnet). These parallel systems often interconnect with the data network for remote monitoring and intersite communication. The contractor shall take great care to not to disturb these systems in any way. The Technology Standards herein are intended to cover data, security cameras, audio/visual, voice and video (VOIP) connectivity provided as a service to the district as a whole and managed by the Technology Services Department.

Unspecified Equipment & Material
Any item of equipment or material not specifically addressed on the drawings or in this document and required to provide a complete and functional installation shall be provided in a level of quantity and quality consistent with other specified items.

This section provides a description of technical and/or performance specifications relative to OUSD’s installation pricing requirements. Specifically, this section has been arranged to present information in the following order:

1.5 PRODUCTS AND MINIMUM PROVISIONS


The Contract Documents generally outline industry standard components to be installed as part of OUSD’s installation requirements. Such identification is intended to be general in nature rather than exhaustive; all quantities, if stated, are subject to validation by Respondent. Respondent is reminded that differences between estimated quantities and those reasonably derived based from the Contract Documents (as well as through bid conferences, job walks, RFB addendums, and other distribution of information) shall be the responsibility of the Contractor; there shall be no additional cost incurred by OUSD for complying with the specifications and requirements of the Contract Documents.

Any variance from those components identified on the drawings and/or below shall be submitted to OUSD/OUSD’s Representatives for approval prior to ordering and installation; the risk for all costs incurred by the Contractor for materials ordered prior to such written approval shall be borne entirely by the Contractor. Nonetheless, it is imperative that the Contractor determine the availability of necessary materials and propose equivalent substitutes as necessary to meet all installation milestones; delays in installations due to lack of product availability are unacceptable. As catalog numbers change frequently, the Contractor must verify all part numbers prior to ordering materials. Clarifications will be issued in response to written Requests for Information (RFIs)
