What is the difference between a Cat5 and a Cat6 RJ45 connector?
A major part of creating a viable network involves the installation of a cabling system. A solid cabling system is a good investment that will not only meet your current networking needs, but will last through your next-generation network as well.
No, it’s not ET calling home. “Alien Crosstalk” is defined as “unwanted signal coupling from one balanced twisted-pair component, channel, or permanent link to another”.
Alien crosstalk is not generally affected by common noise from motors, transformers, or florescent lighting fixtures. Alien crosstalk is specified as “a parameter for cabling to approximate the energy present when all cabling pairs are energized”.
Given that labor costs for installation are much higher than the material cost for cable; your first requirement is to use the highest grade cable available. Cat5e is the most common, but Cat6 is becoming the standard as it is rated for a higher frequency signal, a somewhat higher cable quality, and has tighter specifications for noise and crosstalk. Both Cat5e and Cat6 can handle gigabit speeds.
Both Cat5e and Cat6 use 10BaseT “twisted-pair” cabling, because it is ideal for either small, medium, or large networks that need flexibility and the capacity to expand as the number of network users grow. In a twisted-pair network, each PC has a twisted-pair cable that runs to a centralized hub. Twisted-pair is generally more reliable than thin coax networks because the hub is capable of correcting data errors and improving the network's overall transmission speed and reliability. Also known as “up linking” hubs, they can be chained together for even greater expansion.
Should you install the cabling yourself, or hire a contractor? The smaller the office network, the more tempting it is to install cabling in-house. While this will save installation costs, it is important to be sure that all the cabling is installed and tested to professional standards. If your network encompasses multiple rooms-and/or floors, then hiring a professional cable installer that has experience with data communications networks is the safest and most practical route. General electricians may not be familiar with all the requirements. Experienced cable installers such as Progressive Cabling will know the right grades of cables and connectors and have the knowledge and equipment to install and test a cabling system.
A 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.
VoIP phones have reduced costs for phone communications. The obvious benefit is that you no longer need to use Verizon for your business phone service. You can buy VoIP phones and plug them in to your office cabling and have a high-quality business phone system without the need of a high-priced PBX system in your office.
The side benefit to this solution is that you also do not need to have a dedicated cable to a VoIP phone. This is why. Modern VoIP phones plug into your Cat5 or Cat6 network connection and your computer plugs into the phone. That means that you simply don't need half of your cabling infrastructure.
So, if you want to save money on your phone bill and eliminate half of your cabling infrastructure, switch to VoIP immediately. This is especially important to consider if you are moving or considering a cabling upgrade. At $75 to $165 per drop, the savings are substantial.
I met with the General Manager of a Holiday Inn in Northern Virginia. She manages a 200-unit building in Arlington, Virginia, an affluent suburb of Washington, DC. Her property provides rooms and facilities to handle meetings and conferences for vacationers and business travelers. She told me that she is trying to get wireless access installed into her building because she is losing business and wasting money.
She said that her hotel is providing free Internet access but her competition is providing free wireless access. Clients and management prefer wireless because it is much easier to manage and access. Clients don't like having to plug in a cable and having to make changes to their network settings to enable network access. Management does not like having to deal with multiple failure points in managing the hundreds of routers spread throughout the building. There is one in each room.
So, they have a lot of complaints about Internet access. It is not convenient. Sometimes clients don't even have a patch cable. So, the problems are overwhelming for both sides. Additionally, they have Meeting and Conference Rooms that are not hard-wired. So, every time they schedule a Conference for a business client they also have to pay their Internet Service Provider (ISP) to extend a bundle of network cables into the Meeting and Conference Rooms. As you can imagine, this is a hassle and a large financial expense. It cuts into their profit margins. And it is also a major inconvenience for both the staff and the customers.
We have presented a proposal to install network cabling and I expect to get approval in the coming weeks. It will save them time, money and reduce their efforts in providing reliable and fast Internet to their clients. I will update this posting as things progress.
