Patch Cord Knowledge
Cable General Management
Administration and Labeling for UTP and Fiber Optic Connecting Hardware and Cords should conform to TIA-606-B - Administration and Labeling Standard and Addenda. Cabling system administration, labeling and records are also covered in ISO/IEC 14763-1.
Labeling is the most important part of a System Administrator’s responsibilities. At any administration point in a cabling infrastructure, including patching panels, accurate labels are essential. These will identify pair modularity and tell technicians where the other end of the cable is terminated.
TIA-606-B requires that labels are visible and durable. They must be easily read by anyone carrying out work on the panel and have a design life at least as long as the patching hardware. Hand written labels are unacceptable; they must be printed by a mechanical device designed for the purpose.
Most patching panels have provision for inserting labels between the wiring blocks. These labels are color-coded to identify the origins of cables and include alphanumeric codes to provide additional information about the connections. On a port, for instance, they might identify the cabinet number, the shelf and the circuit board to which that particular set of patch cords is connected. TIA-606-B specifies the color-coding regime shown below
central office connection
user side of central office connection
connections to PBX, mainframe computer,
connections to key telephone systems
first level backbone
terminations of building backbone cable MC to ICs
Second level backbones
termination of building backbone
cable connecting ICs to HCs
termination of backbone cable between buildings
terminations of horizontal cable in TC’s
alarms, security, or energy management
Some Information may be preprinted on labels supplied with the patch panel, but the Installer is usually responsible for supplying additional data.
Labeling Optical Fiber Cross Connects
Unlike labels for copper cross connects, optical fiber labels are not color-coded. However, fiber connectors may be color-coded to avoid joining fibers of different core size or type, which dramatically reduces throughput. Refer to ANSI/TIA-568-C.3 and/or ISO/IEC 11801 for requirements and recommendations for color-coding of multi-mode and single mode connectors. Instead of being inserted in a plastic strip, fiber labeling is often affixed to nearby surfaces such as a module door.
Information on the labels may include:
location of the far end of the fiber, e.g. the closest point to the optical connection in question, where the fiber either appears on a cross connect, appears on a wall or floor connector, or is connected to a piece of wall equipment
building room number
The figure below gives an example of the information contained on a fiber cross-connect label found in Room 3K-326 in Building 3
Note: If the TR/FD does not have a formal room number within the building, the room number should reflect the
informal TR/FD numbering system, which is described in the permanent records kept for each site. The fiber type is
62µm (i.e., 62.5/125 micron), cable 15 is the optical fiber cable between Room 3K-326 Building 3 and Room
1A-313, Building 1, and it is identified by the color code for red.
The starting point for all MACs is the Change Request. The process for raising and recording this request must be simple, efficient and rigidly enforced. Fundamental to this is designing a plain, simple change request form. This is the basic input document for the change management system and if it suffers from omissions or errors the whole change process may fail.
Whether the form is paper-based or electronic, time spent on designing it to capture all the necessary information and minimize risk errors is a good investment. Key information includes: names of staff making and authorizing requests, date, unique identifier number, services involved and of work required and location of connections. The form can also provide space for information about the user’s current service or this data can be obtained from your records.
It is vital to keep records of all patching changes for reference during fault-finding and future moves, adds and changes. The records must include information on where cables go, what applications they support and how many pairs are available as spares. The labeling plan (see labeling section above) tells technicians the source of every cable by simply looking at the outlet or wiring block. In addition, the record system must allow users to track the equipment attached to those cables.
For horizontal links, TIA-606-B states that the following records may be kept:
a) Horizontal link identifier (primary indexing identifier, e.g. 1A-A47)
b) Cable type (e.g. 4-pair, UTP, Category 6, plenum)
c) Location of telecommunications outlet/connector (room, office, or grid location)
d) Outlet connector type (e.g. 8-position modular, T568-B wiring, Category 6)
e) Cable length (e.g. 51m/166ft)
f) Cross-connect hardware type (e.g. 48-port modular patch panel, T568-B wiring, Category 6)
Record systems can be set up using paper-based logbooks, spreadsheets or specialist software. The principles of completeness and clarity apply in all cases; it must always be easy to relate connectors and cords to the devices and services they support. The easier it is to search records of connections, the easier and quicker it is to manage patch cords. For larger systems, this gives a big advantage to software-based methods that allow machine searching of the records.
Intelligent Infrastructure Solutions
Network connections live or die in crowded data centers, wiring closets and telecom rooms, where a single misplaced patch cord can wreak havoc and increase downtime. Intelligent Infrastructure management solutions are designed to help manage patching and patch cords. They can help organizations respond to growing pressures to get MACs done more quickly with fewer resources.
The SOPTO Intelligent Infrastructure Solution integrates copper and fiber patching hardware with system control software to help monitor, document, and administer a complete communications infrastructure. Every port connection is continuously monitored, verified and logged in a central database, giving an immediate alert to any changes.
The system enables simple adherence to the best practices of planning, preparation, execution and validation of changes. Electronic work orders replace paper-based administration and improve productivity. Work is guided at each patch panel by electronic visual and audible prompts, helping to eliminate patching errors. Local and remote monitoring and information display further enhance productivity and ease of use.
