Should we upgrade to Cat6a or to Cat7 cabling?

10 Nov 2023


Cat6a is a much more established standard than Cat7. It is easier to install and has less connectivity issues. We are not going to recommend or bid on a Cat7 solution. Cat6a can run at speeds of up to 10-Gigabit so if that is acceptable for the next 10 years, than we recommend Cat 6a or go to fiber.

We were asked to bid on a cabling project that was fairly straight-forward. It involved replacing the existing Cat5e cable with either Cat6a, Cat7 or fiber cable. The site was an open, standard modern office with a drop ceiling and hollow office walls. The client needed 64 single drops to existing faceplates, three new 24-port patch panels and patch cables.


The need for higher speeds by the client was created by a demand for faster access to larger files from the Server. This potential client was involved with heavy drafting and multimedia applications that require more bandwidth through the cabling system. Cat5e yields up to 1000Base-T, 1-Gigabit, data transfer speed.


The challenge is in deciding on which type of cable to use. Cat6a and fiber are very standard solutions. But Cat7 is not  at all a standard installation yet (and might not ever be one). The problems with Cat7 are that the cable is very heavy,

Microsoft is Ma Bell

12 Jan 2014

Remember the 60s? I do. We had a rotary phone and it made phone calls. Our number was Whitehall 6-4990. And it was an amazing device that allowed us to talk to our friends and family by simply spinning the dial for each number and waiting for someone to pick up the phone on the other end. Back then, Ma Bell had a monopoly and most people probably thought that was fine. Phone service was reliable. The technology seemed like a blessing. The service was affordable although long-distance calls were very, very expensive.

Abandoned Cable Liability Issue

17 Oct 2013
Cabling,Data Cabling Cat5e Cat6/6a Cabling

As tenants come and go in a commercial building, the cabling infrastructure sometimes leaves behind abandoned Cat5, Cat6 and coax cabling. All that needs to happen is for the new tenant to request a reconfigured layout that relocates the main wall closet. Or, sometimes the old tenant will cut away the cabling in order to take the patch panels with them. If possible, keep the wall closet location. And always offer to buy the patch panels from a departing tenant.

How to Install a Patch Panel

27 Jun 2013

The process of installing a patch panel onto a wall begins with the preparing the wall to hold the rack. Most offices have drywall walls. Sometimes the walls are concrete if they lie along the structural boundaries of the building. This installation involved mounting the patch panel onto a wall that is drywall on top of concrete.


The photos below will illustrate what is involved in mounting a rack that holds the patch panel and switch.

Perfect Patch Panel Installation

4 Jun 2013
This project involved installation of 28 double drops into two 48-port patch panels. Each wall plate has two connections with one dedicated to data and the other dedicated to voice. Price Benowitz has a lovely office at 409 7th Street, NW. The building is historic but renovated into a modern office. So, the drop ceilings and hollow walls facilitated a straight-forward installation of the Cat5e network cabling system.

RJ-45 Connectors Made Easy

18 Apr 2013
Network Cabling, Data Cabling ,Cat5e, Cat6/6a CablingWhat is the difference between a Cat5 and a Cat6 RJ45 connector?

The easy answer is:  they are both cable connectors with a standard network plug and socket, often called an “Ethernet jack”.

Cat 5 and Cat 6 are UTP, or Unshielded Twisted Pair cables.  The difference defines the cables as Category (Cat) 5 or Cat 6 UTP cable. Both are terminated by RJ45 connectors.

Cabling Issues

11 Apr 2013

data cabling,,DCOne of the most important things about cabling is to purchase cable not just for what you’re using now but for what you may run in the future.   A rule of thumb is to install the highest-grade cable that your budget allows.


The standard is Ethernet. That means there are two basic types of cables to use: copper Ethernet and fiber optic Ethernet. Copper Ethernet cabling is generally used to connect the data center equipment to the end-user, while fiber optic cabling is used to network the infrastructure and to

"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

A Guide to Network Cabling

Cat 6While WI-Fi and other wireless network technologies have improved greatly over the years, nothing beats the reliability and performance of a wired network in your home or business. One challenge that people face is what kind of cable they need for their needs.


Although there are dozens of network cable types, the fact is only 3 types of network cable is commonly used in home and small business networks: Category 3 (Cat3), Category 5 (Cat5), and Category 6 (Cat6).
