As discussed in Part 1, companies that have a limited budget for network infrastructure may end up buying copper clad aluminum (CCA) cabling to save money. Although marketed as a sufficient substitute for solid copper cabling, CCA cables are far from being the right answer for trimming budgets. Part 2 will continue discussing CCA cabling related issues and counterfeit copper cabling.

Shortened Cable Runs

As lengthier CCA cable runs approach the 100-meter maximum, there will be a decrease of signal strength in comparison to solid copper CAT5e cabling. Reduced signal strength can result in data loss because increased packets of data must be retransmitted.

Unsuitable for Power Over Ethernet (PoE)

Since CCA wires have a higher DC resistance (about 55% greater) than solid copper, its conductors may need to be 60% larger than solid copper to compensate. Without resistance compensation, the drop in voltage will be greater for any channel length.

Longer cable runs of 65 meters or more will surpass TIA’s channel DCR requirements, limiting the available voltage for the device. In addition, higher resistance will result in a faster buildup of radiant heat, which may damage the device.

How to Identify CCA Cabling

CCA wire is also much more brittle than solid copper wire. Identifying CCA is easy because all you need to find is the silver color of the tip of the conductor. Another way is scraping away the thin copper surface of the conductor to reveal the aluminum.

CCA cables also weigh much less than solid copper cables. Go to the CCCA website for the CableCheck™ mobile app (http://cccassoc.org/news/free-apps/), which provides the approximate correct box weights to help detect CCA conductors being used to fraudulently substitute for solid copper conductors.

When a CCA cable is labeled as a Category 5e, 6 or 6A cable or CMP or CMR rated, it is counterfeit cable. It will also be non-compliant with industry performance standards and will pose a hazard by being unable to pass UL fire safety testing.

After receiving the requirements for a network, it is common for designers to prioritize their implementation and integrate them into the format of the design. Occasionally, they initially rely on best practices, instead of focusing on planning. This is unfortunate because the planning process often leads to discovering multiple viable design solutions.

Designers should first make business-centric decisions determining either the solution or design that supports the company’s objectives or strategy. Although it is advisable to follow best practices for network design, reliance on them is more typical on occasions when a network is being designed from the ground up, which is usually not the case for large service providers and enterprises.

Let’s consider optimizing office buildings as a comparison. The standard procedure for civil engineers and architects is to perform an evaluation of a building by identifying existing problems, understanding the organization’s goals, and gathering business requirements. Afterwards, they begin optimizing the office building’s existing features. As examples, this may involve replacing the elevators or expanding the lobby.

The above is similar to the procedure for revamping network design. There will always be faulty designs that were poorly planned. Sometimes they are unable to scale, or adopt emerging technologies, or adapt to changing business conditions. Thus, designers must first make a comprehensive study of the existing business problems, IT requirements, and network design. Next, they should develop solutions that will optimize the present architecture. This may entail redesigning several components of the network. It can also require the addition of a new data center.

In order to choose the correct design choices and technologies, network designers must gather the necessary information that will allow them to make a sound analysis during the planning stage. This also lets them correctly determine the new requirements that will support the company’s business goals. At this point, network designers typically utilize the decision tree and the decision matrix for easing and simplifying the process.

The constraints of network design are existing factors that cannot be altered, often impacting architecture and functional requirements. These constraints can have a significant effect on network design and must be taken into account. Below are the most familiar design constraints that must be addressed by a network designer.

Cost

Cost is certainly a limiting factor that must always be considered during the design process.

Experienced & Expensive Staff

In order to quickly adapt to new technology, a company may decide to hire technical employees who are expert in the new technologies, but cost more in salary. The greater operational costs for their expertise may exceed the benefits from the decreased TCO (total cost of ownership) derived from the latest technology.

Expertise of Staff

It may be the case that the most efficient, cost-saving design with state-of-the-art technology was presented by the network design team. However, the current staff may not have the experience or know-how to implement this new technology.

Infrastructure Equipment

In cases where an organization has not planned how to replace legacy network devices, the situation can lead to severe limitations on network design. This is quite apparent when new protocols and features cannot be supported.

Location

This is a difficult kind of constraint because location involves limitations that have an indirect effect on design. To illustrate, a rural site might be in a region where fiber infrastructure is not present and wireless is the only connectivity.

Staff Training

Due to the lack of experience of technical staff in a newer technology, issues may take longer to detect and repair until they are adequately trained. This will lead to longer downtimes that render a data center nonfunctional, resulting in business losses.

Time

When choosing an architecture or technology, time becomes a constraint when the time frame plays a part in remaining on schedule for the completion of the project.

Structured cabling systems are so standardized that good practices should merely entail following ISO/IEC, CENELEC or Telecommunications Industry Association (TIA) documentation for panel and outlet standards, cable pathway standards, maximum cable and patch cord lengths, patch testing standards, etc. Strictly doing so will invariably result in an installation that is professional and trouble free. In addition, as data speeds grow faster and faster, following industry standards becomes even more crucial.

Improperly installed cabling made up of shorter runs, which do not overly stress the system, may function well enough. In addition, data speeds may be quite beneath the cable specification capacity. As an example, CAT5e carrying 100Mbps and capable of 1Gbps will have ample margin of error. However, structured cabling systems still need qualified technicians for proper installation supporting maximum data speeds over the entire network as required.

The following will discuss the five most common errors of structured cabling. Remember to call an experienced and expert cabling installation team to get the best results for your company’s project.

Error No. 1

Considering cables as merely wiring is the first error. They are actually very important electronic components that provide the pathway for data from point to point within a network. These points may be a desktop PC, a network switch, server, router, and wireless access point. When you consider that cables make these connections possible, then you can understand how important it is to make sure that the cabling is of high quality and properly installed.

Error No. 2

Running data cables near power cables is the second error. Even when cables are screened, this practice is unsound. When data cables are running near and parallel to   power cables, noise emitted by power cables may infiltrate data cables. As the load carried by power cables fluctuate, resulting spikes or surges may radiate into the data cables, creating undesired noise decreasing the quality of the data transmission.

Part 2 will discuss three more common errors of structured cabling.
