Open Cabling system is solution that provides to clients with the most complete cabling system and expendable in the future. Since it is open system, it can integrate with all IT and telecommunication equipments of all manufacturers in the world.

1. Sybsystems of Structured cabling

  • Work Area
  • Horizontal Cabling
  • Telecommunications Room
  • Backbone cabing
  • Equipment Room
  • Entrance Facilities
  • Administration

 

  • Work Area

Work area is where the horizontal cable terminates at the wall outlet, aslo called the telecommunication outlet. In the work area, users and telecommunications equipment (PC, Printer, and Telephone) connect to the structured-cabling infrastructure. The distance from outlet to equipment is recommended within 5 meter, this distance is limited with electric outlet less than 1 meter.

  • Horizontal Cabling

The horizontal cabling is typically connected into patch panels and switches/hubs in telecommunications rooms or enclosures. This distance is recommended within 90 meter.

  • Telecommunications Room

The equipment room, which is a centralized space specified to house more soohisticated equipment. This room is intermediate cross-connect and main cross-connect. There are two type of termination cable is using the termination subsystems cabling is that inter-connections and cross-connections

  • Backbone Cabling

Backbone cabling is also sometimes called vertical cabling, cross-connect cabling, riser cabling, or intercloset cabling.) Backbone cabling is necessary to connect entrance facilities, equipment rooms, and telecommunications rooms and enclosures. It is aslo cabling system to connect betwwen these building in a campus environment.

  • Equipment Room

The equipment room, which is a centralized space to stored the actived-equipment, the terminal equipment such as Patch Panel, optical rack … is the intermediate connection between the cable system from the Entrance Facility and the outlet

  • Entrance Facility

The entrance facility (building entrance) as defined by ANSI/TIA-568-C.1 specifies the point in the building where cabling interfaces with the outside world. All external cabling (campus backbone, inter-building, antennae pathways, and telecommunications provider) should enter the building and terminate in a single point.

  • Administration

Administration, which is a managed system, it is includes the labeling, documentation, and as-built drawing to be helped the system admin can manage all of equipment, easy in maintenance, and upgraded or extened the system.

2. The modeling in the structured cabling system

The structured cabling system is designed upon two models, which are Distributed Network Architecture (DNA) and Centralized Network Architechure (CNA).

2.1 Distributed Network Architecture (DNA). This model, the cables will be store at intermediate rack at floor of building or IDF. From this location will be connected to MDF via Backbone.

Advantages:

  • Ideal for large building and nulti-building campuses
  • Based on TIA/EIA & ISO Standard Architecture
  • Low fiber count backbone

Disadvantages

  • Electonics are distributed ( convert, switch)
  • MAC’s are more complicated
  • Administration time and costs are high
  • Port ultilization and efficiency typically poor

 2.2 Centralized Network Architechure

CNA is all of cabling system will be centralized to main rack at MDF room

Advantages:

  • MAC’s are much easier and less costly
  • Administration time and costs are lower
  • Increated port utilization and efficiency
  • Based upon TIA/EIA TSB-72
  • Less space utilized in Telecommunications closets
  • Quick path for network migration
  • Fewer points of failure switch

Disadvantages

  • Initial installation costs
  • Higher cost of optical electronics
  • Perceived single point of failure

3.Telecommunications Cabling Standard

The structured cabling system is designed and implemented based upon cabling system standard for commercial buildings and between buildings in campus environment. The public existing standard is TIA/EIA.

3.1 TIA/EIA-568B

The TIA / EIA-568B is the standard for telecom cabling connectivity for commercial buildings, commonly used in the Americas and Asia.

Purpose: Allows planning and installation of structured cabling systems for commercial buildings. Designate a common cabling system that supports multiple product environments with multiple vendors

3.2 TIA/EIA-569B

The TIA / EIA-569B is the standard for space and cabling for commercial buildings. Include pathways (cable paths) – and space (telecommunications).

Purpose: Standardize design and construction specifications within and between buildings, support signaling environment and connect telecommunications equipment.

3.3 TIA/EIA-606A

The TIA / EIA-606A is a standard for the management of telecommunications infrastructure in a commercial building.
Purpose: Provides a unified administrative support system, independent of the applications. Establishing guidelines for owners, users, manufacturers, consultants, contractors, installers, administrators, and others involved in the management (and labeling) of telecommunications infrastructure.

3.4.   ANSI-J-STD-607A

The TIA / EIA-606A is a standard for the management of telecommunications infrastructure in a commercial building.

Purpose: Provides a unified administrative support system, independent of the applications. Set up guidelines for owners, users, manufacturers, consultants, contractors, installers, administrators … that are involved in the management (and labeling) of telecommunications infrastructure.

3.5.   TIA/EIA-942

The TIA / EIA-942 is a standard for data center cabling.

Purpose: Standardize the design and installation of cabling systems for a data center infrastructure that optimizes the use of high density data centers. Designate a common cabling system that supports multiple product environments with multiple vendors in a data center.

3.6. TIA/EIA-862

The TIA / EIA-862 is a standard applicable to the design of an automated control system for a commercial building. Allows automatic control of all security systems, CCTV systems, fire alarm systems, environmental management systems, temperature, humidity, light management system inside and outside the building …

Purpose: The TIA / EIA-862 standard unifies cable technology, architecture, design, installation, and measurement testing for a full-service building automation system (BAS) in commercial buildings. The system allows to meet all equipment, cables, connection standards, different technologies in the same structured cabling system. Other important features of “low-cost” systems (audio / video paging, service / equipment alarms, non-data communications, wireless access points) supported by telecom infrastructure are also required of this standard.
