While you were gathering information to recommend transmission media for the medical instrument manufacturer,?
you noticed that some of the telco
rooms were in disarray. For one thing you notice sloppy cable terminations.
Further, cables are pulled tightly around the corners of racks and intertwined.
You also suspect that the horizontal wiring spans exceed TIA/EIA 568 recommendations.
And to top it off, cables, ports on connectivity devices, and data
jacks arent labeled. However, the companys network manager tells you she
and her staff dont have time to attend to these oversights. What can you say
to convince her that the minor oversights could have a significant impact?
What do you consider the single most important reason to pay attention to
faulty terminations and excessive horizontal wiring spans? Why is it critical
to label patch cables, ports, and data jacks?
I would tell her that she was probably one of those people who did not do their own homework in school (HINT) and that while that may fly in the school it does not fly in the real world and then fire her for being lazy.
Proper Network Cabling for Your Office
Today's global economy is more competitive than ever, which means even the small details can make a huge difference if your company's productivity. One way to stay up to par with your competitors is to assemble your employees into separate teams to undertake different specific projects. This will most likely force you to relocate personnel within your work facility. As seating arrangements change, the layout of your office is likely to change as well. That means your Utah network cabling system will change as well.
There is a standard design for telecommunications and network cabling in an office building, a standard that the construction industry follows faithfully. It defines not only how the installed cabling should be constructed and how it should perform, but also how the cabling should be distributed throughout the building.
The horizontal cabling run that extends from a communications room located on the office floor to the wall outlet that serves a workstation or desk located on the same floor is commonly made with UTP copper cabling. The horizontal cabling is installed in a physical star typology. The star typology means that each work area is wired to a horizontal cross-connect. Its own dedicated copper cable serves every workstation, but the length of the cable run is limited to about 300 ft. This cabling extends horizontally along the floors, walls, or ceilings.
The original design standard was set up so that whenever a change is made in the layout of one or more workstations in an office, you could avoid the unnecessary expense of redoing the entire horizontal cabling from the telecommunications closet to each workstation. The standard was changed recently because the construction industry believed it shouldn't be necessary to rip out the existing conductors, install new ones, and re-terminate the wires at a workstation when conducting moves, additions, or changes.
Higher performance Utah network cabling has been developed, creating new ways to connect the cabling and higher-speed network switching. Because of these new cabling systems, there needed to be a new cabling layout design concept called zone cabling. This new layout design offers improved networking performance an attractive return on investment whenever moves, additions, and changes are necessary.
There are two different areas that zone cabling focuses on. The first is the insertion of a piece of equipment within the horizontal cabling run and placement of some active/powered network equipment within the office area. With this kind of project, the fiber backbone cabling would need to be extended into the work area before converting the network cabling to copper cabling for the horizontal run. The second zone cabling area involves inserting an intermediate point somewhere in the horizontal cabling run in the office area close to workstations that allows for reconnection or reconfiguration of conductors within that defined area. This allows the cabling network to serve six or eight workstations from one point
There is another standard out there that enables you to change an open-office layout without disturbing the horizontal cable. When this type of standard is used, multiple horizontal cables are terminated in a sturdy enclosure at a common location, such as within a furniture cluster or similar open area. It also allows you to use longer cords in a typical installation.
Companies are changing their office locations and office layouts more and more these days, which makes it more important for Utah network cabling managers to have a system for adapting the cabling to reduce the expenses involved.
