Residential Cabling Topologies and Standards
Residential cabling standards are largely the same as commercial cabling installations standards.
The differences come mainly from the lower level of usage in residential installations.
Cable Grades
Unlike commercial cabling, there are two grades of cable recognized for residential cabling.
Grade 1
Grade 1 cable provides a generic cabling system that meets the minimum requirements for telecommunications services. These include telephone, satellite, community antenna television (CATV) and data services.
Acceptable cables for this grade are category 5e and above, 4-pair unshielded twisted pair cable and one 75-ohm coaxial cable.
Figure 8.1.1
Introduction to Network Cabling Fiber Optic-Based Systems

5. Introduction to Fiber optic-Based Systems and Safety8
Grade 2
Grade 2 cable provides a generic cabling system that meets the requirements for basic, advanced and multimedia telecommunications services. It should handle current and developing telecommunications services. Acceptable cables for this grade are two category 5e or higher, 4-pair unshielded twisted pair cables, two 75-ohm coaxial cables and optionally 2-pair Fiber Optic cable
New Term
Grade 1 Cable - Provides a generic cabling system that meets the minimum requirements for telecommunications services.
Grade 2 Cable - Provides a generic cabling system that meets the requirements for basic, advanced and multimedia telecommunications services. Fiber Optic is grade 2 cable.

Structured Cable
The various cables needed for different telecommunications services can be bundled together in a single sheath and placed all at once. You pull the entire bundle once and then unbundle the various components and connect them to the various system outlets.
Structured cabling can often contain elements like Fiber Optic cable that are not needed in the current installation, but that could be needed in the future. This is referred to as future-proofing an installation.

The Smart Home
Structured cabling can be an important factor in the "smart home" technologies being installed in many new homes. Smart Home technology involves a number of systems performing household maintenance functions in addition to the traditional voice, video and data functions. Such systems require extensive cabling, the sort of cabling that structured cable provides.
Some of the systems that can be run by smart home technologies are:
computer networks
video distribution
security/alarms
automation systems telephone systems

Elements of Residential Cabling
Residential cabling is made up of the following elements:
the gateway.
the auxiliary disconnect outlet.
outlet cabling. outlets.
The Gateway
The entrance point to a residence is called a gateway. It serves the same purpose as a commercial entrance point. Cables from the outside world are connected to cables on the inside of the building at this location. The cables from the outside offer services from various outside providers, such as telephone, tv and data services. This location is sometimes referred to as the demarcation point. These connections are accomplished in a cabinet or other distribution device.

Gateway - The entrance point of outside cables into a single-family residence. Often called the point of demarcation.
auxiliary Disconnect outlet (ADO) - An outlet for the cable from each service provider to allow for disconnecting that service.
The auxiliary Disconnect outlet (ADO)
Somewhere close to the gateway should be an outlet for the cable from each service provider to allow for
disconnecting that service. Often this outlet is right in the distribution device. This outlet is referred to the auxiliary Disconnect outlet

Activity 1.1 The Tools of Termination
Outlet Cabling
outlet cabling runs from the distribution device (usually at the gateway) to the outlets for the various devices the cabling serves. In a commercial installation, this would be called horizontal cabling.
outlets
A point of connection between the outlet cabling and the devices it serves is the outlet. Usually the outlet is a faceplate in the wall. Outlets should accept at least two terminated fibers. Standards recommends at least one outlet location in each of the following rooms:
Kitchen
Each bedroom
Family/great room
Den/study
Other standards also apply concerning the spacing of outlets. Connections to the devices are normally made with patch cords.
Figure 8.5.1

14. Residential Cabling Topologies and Standards
Introduction to Fiber optic-Based Systems and Safety 8
Residential Cabling Topologies and Standards
Topology
The cabling topology recommended by standards for residences is the star (home run) topology, where cabling for each device is connected to a central core or distribution area. Because of the shorter cabling distances in residences, this central core is usually the gateway.
This makes it easier to MAC (Move, Add or Change) the topology. After a cabling system is in place, the majority of the technicians job will involve MAC. 1
The Star Topology
New Term 14
outlet cabling - Cabling that runs from the distribution device to the outlet, comparable to
horizontal cabling in commercial installations. outlet - Provides a point of connection between the outlet
cabling and the devices it serves. 16 8 13 12 6

Recommended Cables
The three types of Fiber Optic cable recommended by the standards are:
two-fiber 50/125 multimode cable.
two-fiber 62.5/125 multimode cable. two-fiber single-mode cable.
two-fiber single-mode cable.
Due to the short distances involved, it would be rare to see single-mode cable in a residential installation. Color coding for cable hardware is the same as in commercial installations: beige for multimode; blue for single-mode.

16. Residential Cabling Topologies and Standards Cabling Distances
Introduction to Fiber optic-Based Systems and Safety 8
Residential Cabling Topologies and Standards
Cabling Distances
The standards set 90 meters as the maximum
distance for each outlet cable (from the
distribution device to the outlet). Another 10
meters is allowed for patch cords and cross-
connects, giving an operational distance of 100 meters
There should be an outlet in each room and an additional outlet for every 3.7 meters (12ft) of unbroken wall space.
Figure 8.6.1

17. Residential Cabling Topologies and Standards
Introduction to Fiber optic-Based Systems and Safety 8
Residential Cabling Topologies and Standards
Outlets should be arranged so that nothing that has to be connected would be more than 7.6 meters (25ft)from an outlet.
Backbone cabling should not exceed 2000 meters and should be free of splices and unnecessary connections.
Cable Slack
When installing a cable run, it's good practice to provide additional slack at both ends, to accommodate future cabling system changes. Allow about 1m (3ft) at the distribution device and .25m (8in) at the outlet. Once the cable is terminated these lengths will be reduced. Use cable management devices in both the distribution device and outlet as needed.

entrance Facility (EF)
As in commercial structures, the entrance facility is the place where outside cables meet inside cables. The EF is often called the demarcation point. This facility could be a cabinet or a closet or a room, depending on the size of the building and the level of cabling required
main Terminal Space
The main terminal space contains the cross-connects from outside cable to the building's cable system. This area could be at the Entrance Facility or it could be some distance away, depending on the layout of the building.
Backbone Cable
Backbone cable runs from the main terminal space vertically up to the various floors of the building.

Floor Serving Terminal
Backbone cable runs to various floor serving terminals from which cabling is sent to the floors served by the terminals. Floor service terminals serve the same function as telecommunications rooms in commercial buildings, except that one terminal can serve up to
three floors.
DD and ADO
Each tenant space has its own Distribution Device (DD) and auxiliary disconnect outlet.

Estimating the Job
When considering a cabling job, it's always a good idea to estimate the amount of materials needed and the cost of these materials. Here are some guidelines:
The amount of cable you need depends on the topology you choose. For example, for the recommended star topology, you need enough cable to reach from the distribution device to each of the outlets you are going to install, plus the recommended slack for each of those runs.
Remember the standards concerning unbroken wall space when deciding how many outlets to install in each room. There should be at least one for every 12ft.
For twin fiber cables, which the standard specifies, each termination requires two connectors or one duplex connector.
It is wise to add a cushion of 10% to your cable length estimates to be sure they are adequate.
