Cat5/5e Network Cabling Usage and Methods

27 Aug 2009

Category 5


Ethernet_RJ45_connectorCategory 5 cable includes four twisted pairs in a single cable jacket. This use of balanced lines helps preserve a high signal-to-noise ratio despite interference from both external sources and other pairs. It is most commonly used for 100 Mbit/s office computer networks, such as 100BaseTX Ethernet, although IEEE 802.3ab defines standards for 1000BaseT - Gigabit Ethernet over category 5 cable.

Category 5e


Cat 5e cable is an enhanced version of Cat 5 that adds specifications for far end crosstalk. Although 1000BaseT was designed for use with Cat 5 cable, the tighter specifications associated with Cat 5e cable and connectors make it an excellent choice for use with 1000BaseT. Despite the stricter performance specifications, Cat 5e cable does not enable longer cable distances for Ethernet networks: cables are still limited to a maximum of 100m (328 ft) in length.

Connectors and other information


quote iconThe cable exists in both stranded and solid conductor forms. The stranded form is more flexible and withstands more bending without breaking. Taking these things into account, building wiring (for example, the wiring inside the wall that connects a wall socket to a central patch panel) is solid core, while patch cables (for example, the movable cable that plugs into the wall socket on one end and a computer on the other) are stranded. Outer insulation is typically PVC or Plenum. Plenum cable is designed to go into drop ceilings that are used as air returns for the air-conditioning systems in modern office buildings.

Nearly always, 8P8C modular connectors, commonly referred to as "RJ-45", are used for connecting category 5 cable.

Michael Price and MarketUS.com Rip Off

2 Jul 2009

On April 9th of 2009, I hired MarketUS.com to get my firm onto the GSA schedule. I agreed to a do-it-yourself (DIY) solution. On March 9th of this year I worked with Jeff Connell in Sales and I agreed to the DIY service. I was told about Coaching Services that

MarketUS.com created a fake sales receipt

10 Jul 2009
I am fighting MarketUS.com and I finally, from my bank, got a copy of the fake sales receipt. They claim that I made 20 hours of support calls. I made one call that lasted about 20 minutes. Click here to see a copy of the fake invoice.

I wonder if Guy Trone is willing to lie about the number of calls I made to MarketUS.com. Are you, Guy?

Seeking MarketUS.com victims

15 Jul 2009
I hired MarketUS. It is owned by Michael Price. I hired them to get me onto the GSA schedule. They ended up stealing money from me and justifying it by saying I ordered "Coaching". They lied. I am out $9,000 with little to show for it. I could pursue the DIY GSA that cost me $5,000. But they are insisting that I ordered the Coaching and my anger and frustration is making it impossible to work with them. Have you worked with Mike Price, Deane Trone, Jeff Connell or Guy Trone at MarketUS.com?

Letter to Reporter at Sun Sentinel in Fort Lauderdale

27 Jan 2010

I wrote this letter to Cyndi Metzger, a business reporter at the Sun Sentinel in South Florida, the local newspaper of MarketUS.com. I wonder if Michael Price subscribes?


Dear Ms. Metzger -


My name is Stuart Kushner. I am a small businessman in Washington, DC. My company is www.ProgOffice.com. I have a story. I hired www.MarketUS.com to get my company on the GSA schedule and they ended up stealing $4,000 from me. They transferred funds from my bank account (I naively gave them access), created fake invoices, and kept $4,000 of my money. Since they stole from me, I was unable and unwilling to work with them. So, the initial (authorized) payment was a waste. So, I am out $9,000 and I am not on the GSA Schedule.

Bringing Innovation and Competition back to Windows

13 Jul 2009

 Data Cabling ,Cat5e,Cat6/6a CablingWould you consider using the cell phone you had in 2000? Think about it. Back in 2000, the early models of the Treo were hot products and by today standards they are very inadequate.


As for me, I am still using Word 2000 and even if you have the more current version, I doubt that there are any features in it that are compelling. Microsoft has a stranglehold on the PC industry. They dominate the operating system and the applications market. They don't have any formidable competitors. Test yourself. Who is Microsoft's biggest business software competition? It isn't Google because Google is giving away their Google Apps. It isn't Apple because Apple is a hardware manufacturer. They don't develop business applications that compete with Office.

Multi-tasking cell phones, the next wave

3 Jul 2009

Network Cabling,Washington DC, New York City palm_preThe golden age of PCs was DOS. Why? Because the OS made it very easy to write quick, powerful programs. DOS was a simple single-tasking operating system. It was easy to program on DOS because their were a lot of vendors with competing compilers that made writing applications relatively simple.


With the release of Windows, Microsoft made things much more complicated and then made it so complicated that Microsoft is now one of the ONLY company that can develop sophisticated applications on Windows. Unfortunately, Microsoft is not really very good at programming and does not need to innovate because they don't have any competition.
