"Structured cabling” is a complete system of cabling and associated hardware which creates a telecommunications infrastructure. This infrastructure can serve a range of tasks, such as providing telephone service or data transmission through a computer network.

Every cabling system is unique. Variations in the structure of the facilities housing the installation, the specific cabling and connections needs, use and function, as well as customer needs requires standardization to ensure acceptable system performance from increasingly complex systems. The American National Standards Institute (ANSI) is the responsible organization

The Good, the Bad, and the Ugly: Cabling Lessons Learned

14 Dec 2012

Cat5, Cat6 data cables ,connected to serversA magnetic field when running low voltages. Unfortunately, when this unshielded cabling creates a magnetic field created. Any electrical cabling bear by disrupts communication, slowing transmission or preventing Network cabling is a tricky. Even with a solid background, technicians without adequate knowledge and training can make mistakes that may shut down an entire system. Here are some typical mistakes seen in network cabling.


Plan for the Future.  Cat5 may be the cheaper option, but can cause problems when upgrading is needed. Install Cat5e or Cat6 cables with options for upgrades to save labor costs.


Don’t Mix and Match. Twisted pair cabling was often out of the price range for many companies, so priority was given to data, while voice had with cheaper cabling. Now, VoIP has made voice equal to data in importance and need. Fortunately, a typical VoIP phone has a built-in Ethernet connection or pass-thru that is compatible with almost any data cable, which decreases installation costs.


Don't put Electrical Cables Next to Data Cables. Data cables use twisted pairs of wires inside that help produce transmissions altogether. This generally happens when the cables are running parallel, so if your cable is near a power line, lay them perpendicular to the power line.


 Not Laying New Cable When You Need To. Ethernet switches are convenient, but can be misused. Mini-switches are often added to provide a few extra ports; but this can cause bottlenecks and instability. Add extra cable instead, if more network resources are needed.


Forgetting Cable Management. “Ladder racks” add extra cost to an installation, but they also make the installation look better, run better, and easier to maintain and update. Also, don't forget to color code or label your cables, so technicians can actually find the right cable later.

Project Objectives and Details based on site survey by Richard Elbe


Number of Drops: 110 total cable drops

  • 47 double network drops

  • 1 single network drop

  • 3 network printer drops

  • 3 media box wallplates with (2 HDMI, 2 VGA and 3 RCA Jacks)


Ceiling: Non-plenum, separate ducting allows for Cat6 PVC cable rather than the more expensive plenum cable.

Racks: 6' x 19" Relay Rack

Switches: Five 24,port Netgear Gigabit switches that will leave room for 4 ports per switch for future expansion of the network.

Do Not Use Basket Tray against a Tight Ceiling

8 Aug 2012

When a new office design is in its initial stages, it is critical to consider proper handling of utilities, power water and cabling inside the walls and ceiling. For cabling, it is necessary to use hooks to hold the cables above the drop ceiling. When the installation of cable involves large numbers of cables traversing lengthy expanses, it is normal to install cable ladder trays up in the ceiling to carry the bulk of the cable along the main corridors of the office. Cable ladders vary in quality and cable handling capabilities. The amount of cable and the budget of the project will determine the type of cable ladder that will be built.


A higher quality cable ladder will, in the long run, save time and money during the installation phase of a cabling project. The alternative to a cable tray is to install cable conduit. Considerations in choosing to use a cable ladder tray system include the following:

US Court of Appeals Veterans Affairs – Cabling Project Notes

18 Jun 2012

Project Objectives (Do not call, this project has been COMPLETED)




Number of Drops: 360 (140 duals, and 20 quads)

Ceiling: Non-plenum, separate ducting

Racks: Enclosed, 19”, will already be installed by customer

Switches: Provided by customer, 48 port

Patch cables: None necessary. They will provide patch cables from wall plate to computers and from patch panels to switches.

Labeling and documentation of all cabling is important. How this looks is important to them. Please provide a spreadsheet of all wallplates and rooms.

  • Location is behind elevators.

  • All workstation runs will terminate in wiring closet behind elevators.

  • We will mount patch panels in this closet on the wall. Use 24port, Cat5e, patch panels.

  • They will mount racks for switches.

  • 4 pairs of fiber will run from the closet to the server room on the same floor. We are to provide the cabling plant for the fiber.

















Office Cabling Network Cabling

Server Room:




  • 2, 24 port patch panels per rack.

  • Cabling plant for fiber to switch closet.


Existing server room


Click HereThey want cable management hardware to be part of the solution. What you see in this room is what they’re cleaning up and looking to make high end and professional in the new location. Photos here include existing fiber. Note the ceiling cable management rack. In the new location these will be in place in the server room and along the ceiling in the main hallways.












New server space - Roughed in area they’re moving to.




 

 

 

 

 

 

 

 


General Floor Space:



  • Quad drops in each office and cube in the technology area

  • Dual drops in all other offices

  • 6 drops for cable t.v.

  • Wall facing outside is already dry walled and insulated


Part of that wall has large window with wall space under it. Customer is unsure if drops will go there or anywhere along that outside wall.

Includes the outside wall. They’re not sure if there will be drops along this wall. If so it’ll be interesting because of the insulation. Also note that they MAY want drops under the windows along this wall.

There are some pictures of the ceiling details. Also note that the client will already have cabling runners ceiling mounted down the middle of the two main hallways to the server room.



























Special Fiber Optic Line Item Bid:


US Court of Appeals wants this as a line item so they can choose to add this work or not when they’re doing the budget.

Fiber runs between floors. The floor plan represents the 6th floor. 14 runs broken out as follows. A single 6-strand fiber cable will be run from the 6th to each floor in the table below. Three strands will be connected and three will be left as spares.



























# of Runs Floor
3 11th
3 10th
3 9th
3 2nd
2 Mezzanine

12’ ceilings, concrete floors.

Conduit already exists between the floors. We have to repack the conduit we use with fire stop putty to meet fire code. See photos of the “Switch closet” for conduit images.
