Section 16711
2002-02-08 Voice and Data Cabling
This section includes requirements for cabling systems for voice and data, primarily for projects which use primarily Unshielded Twisted Pair (UTP) wiring with some Optical Fibre cabling for backbone connections.
This Section is primarily for data and vice cabling. Use this section in conjunction with 16712 for cable testing. For projects involving other cable types and extensive electrical work, use section 16972 from the Infrastructure master specification.
Where a limited amount of other electrical work is included, use this Section in conjunction with Sections 16005 and 16050.

Data Sheet – Voice and Data Guidelines
Section 16711
2002-02-08 Voice and Data Cabling
Following are voice and data cabling guidelines for Infrastructure projects which must be considered when designing communication cabling installations.
Workstation Cable Installation
.1 Use 4-pair Category 5 enhanced UTP for data wiring unless special conditions exist. Use the same cable type for voice wiring.
.2 Dual strand fiber multimode cable may be considered for long-term or special needs occupancy.
.3 When installing cabling in interior wall to outlets, flexible or EMT conduit should be used. However, where existing partitions do not permit the installation of raceway, cable pulled into the partition and plaster rings are acceptable.
.4 Size boxes and housings to accommodate cable population and minimum bending radii, particularly when fiber is being installed or future installation is anticipated.
.5 For long-term occupancy, use modular type outlets having inserts that can be changed by plugging in a new insert otherwise, use outlets and jacks where the cable is directly connected to the jack.
Backbone Cable Installation
.1 The type of cable used for data backbones should be determined by the User's needs. UTP and Fiber are acceptable for use as data backbones and may be used in combination as necessary. Fiber is the preferred choice in long-term occupancy situations.
Telecommunication Closet Installation
.1 Terminate data cables on patch panels and outlets. All panels, outlets and jacks are to be Category 5 enhanced data-grade.
.2 Arrange terminations in numerical or alphanumerical order.
.3 Label cables, panels, and ports.
