10 Reasons we recommend Velcro

Datcom carries VELCRO® brand fasteners in both riser and plenum fire rated varieties as well as cable ties. Both are used for keeping cords, wires, and even hoses contained and yet there are several situations where we would recommend Velcro over the cable ties.

Within TIA 568C.0, it states that:
Cable stress, such as that caused by tension in suspended cable runs and tightly cinched bundles, should be minimized. Cable bindings, if used to tie multiple cables together, should be irregularly spaced and should be loosely fitted (easily moveable).
Additional guidance can be found in the BICSI Information Transport Systems Installation Methods Manual (ITSIMM), 5th edition, which reads:
Use hook and loop straps to secure the cables. The hook and loop straps should be evenly spaced throughout the dressed length. Hook and loop straps should be used to prevent a change in the physical geometry of the cable that typically results from use of nylon tie wraps.

Here are our Top 10 Reasons for recommending VELCRO® brand fasteners

  1. Velcro causes less cable stress
  2. Velcro has a wider footprint and therefore more support
  3. Velcro requires no tooling
  4. Velcro is available in Riser and Plenum versions
  5. Velcro is reusable and recyclable
  6. Velcro is available in multiple colours
  7. Velcro is easily movable and adjustable
  8. Velcro works with a variety of cable managers and enclosure holds
  9. Velcro is more flexible
  10. Velcro is available in "Cut as you require" lengths
Although you can ensure that cable ties do not cinch a bundle of cable using specified tension tools and applicators, to be safe we would advise using Velcro for any critical cabling medium.



How to deliver professional cable and network testing documentation


Professional cable installers want to exhibit the highest level of quality and standards in offering services to the customer. In doing so, maintaining proper documentation is best business practice that can pay off both during the job and after it’s completion. 


  • Makes sure the job is done right
  • No aspect is omitted
  • Provide the customer with printable documentation
Keeping detailed documentation ensures that the job is done right and that no aspect of the service installation is omitted. Documentation identifies each step of the entire installation project for both managers and clients. Documentation can be customized according to the site specifications and the type of installation being performed.

The Testing Process

Providing the customer with detailed documentation is a sign of a quality and professional install.  It demonstrates attention to detail and thoroughness which is the hallmark of a job well-done. Besides, modern handheld devices and software make it both quick and easy to record and report on the different facets of the installation, and they make it easy to print specifications when needed.
It is essential that results of each test be recorded as soon as the test is performed — avoiding loss of data and ensuring the results are included in the final report. Additionally, it is of the imperative to upload to your computer software all the data and readings that were taken during the testing process so that this information can be used to populate your report.

The Final Report

When the installation is complete and all the testing data from the installation has been uploaded from your test equipment to your computer, you can compile the final report.  Your cable test report will be organized in a logical user friendly format.
It is up to you to decide which values are relevant based on who the report is being distributed to. For example, a report that is sent to a non-technical client would be different from one that sent to an engineering firm or your main office.
It is recommended that detailed results be included in the final reports.  This detail can aid in future troubleshooting as well as satisfying the warranty requirement for some manufacturers.

Correct Labeling

Professional installers understand that detailed labeling is essential and it should map directly to your documentation. Remember…good documentation and cable labeling go hand in hand.
Each work area outlet is commonly labeled with the floor, room, patch panel and the port where it originates. If documentation or cable labeling is not provided, then a proper installation has not been completed.

Proof In The Reporting

Accurate reporting and labeling provides a means for quantifying the installation and documenting that it was done correctly. Furthermore, it provides an overview of the entire process that can be very useful in the future for troubleshooting problems, choosing upgrades, moving devices and/or adding or making hardware changes to the installation.
Handheld testing devices such as the Net Chaser™ which are used to troubleshoot signal, connectivity, and cabling issues, offer several printing options that can be presented to the client based on their needs.  Cable installers often bring portable printers allowing them to immediately print and provide the final report prior to leaving the job — further improving customer satisfaction.
Platinum Net Chaser™ handheld testing devices generate concise and informative deliverable reports that list all of the technical specifications that technology personnel and management would need for strategic planning and maintenance. The reports are easily customizable with your company logo and contact information giving your reports a professional look and feel.

10 Advantages of Emerson's Smart Rack PDUs

In the world of power management selecting the right product can sometimes prove to be difficult, but in the PDU market place the choice has never been simpler to make.

Emerson Network Power’s MPH2 is the most intelligent, high-availability line of managed rack PDUs. They offer remote monitoring and control capabilities as well as environmental input options, with multiple power input selections and output configurations along with best in class cost and time saving features.


10 Advantages of the MPH2 PDU Series from Emerson

The importance of testing structured cabling

As the data supported by the structured cabling we use in our businesses becomes more critical, so too does the need to test and ensure its performance. In general there are five categories of testers; each plays an important role in the health of the networking environment.


1. Trouble shooting testers – Tone and probe generators are a great example and are used to find unlabeled cable and breaks.

2. Continuity testers – These are usually used to ensure that the wiring and pinning configuration is correct.

3. Verification testers – These testers are generally digital units which may or may not provide test results and primarily ensure wiring and pinning configuration as well as speed performance of the installed cabling.

4. Diagnostic testers – These testers have a variety of features which may include subnet mapping, Bit error rate testing, PoE testing and may include other traffic analysis tools.

5. Certification testers – These are industry recognized testers which are rated with levels according to the standards for the submission of test results to a manufacture of premise wiring connectivity in exchange for an extended manufacturer warranty.

In structured cabling networks, copper cable certification is achieved through a thorough series of tests in accordance with Telecommunications Industry Association (TIA) or International Organization for Standardization (ISO) standards. This level of certification is usually obtained in order to submit test results to a manufacture of premise wiring connectivity in exchange for an extended manufacturer warranty. Contractors through whom this type of warranty is provided are usually responsible for such testing; however sometime 3rd parties have been contracted by the end user in order to verify a contractors work independently. Generally these tests are done using a certification-testing tool, which provide “Pass” or “Fail” information. 

The ANSI/TIA-568-C.2 standard specifies electrical performance requirements for installed UTP cable and connecting hardware for each recognized category, and field test parameters are listed in the table below.


There are two types of field tests; one called the permanent link test and the other channel link test.

The permanent link test configuration includes a length of horizontal cable and one connector attached to each end. One optional consolidation point connection is also permitted. The permanent link runs from the cross-connect panel in the TR to the work station outlet. The permanent link overall length must not exceed 90m (295ft).

The channel test configuration includes a length of horizontal cable up to 90 meters, a work area cord, and two patch cord cross connections. One optional consolidation point connection is also permitted in the channel. The channel overall length must not exceed 100m (328ft).

Performance tests and their procedures have been defined in the ANSI/TIA/EIA-568-B.1 standard and the ISO/IEC 11801 standard. The TIA standard defines performance in categories (Cat3, Cat5e, Cat6, Cat6A, Cat8) and the ISO defines classes (Class C, D, E, EA, F and FA). These standards define the procedure to certify that an installation meets performance criteria in a given category or class.

IEC 61935-1 ed 4.0: Testing of Balanced Communications Cabling in Accordance with ISO/IEC 11801


Part 1: Installed cabling, specifies requirements for field test equipment used to certify class D, E, EA, F and FA cabling as defined in ISO/IEC 11801.


Level IIE test equipment or better is required to test class D cabling (100 MHz)
Level III test equipment or better is required to test class E cabling (250 MHz)
Level IIIe test equipment or better is required to test class EA cabling (500 MHz)
Level IV test equipment or better is required to test class F cabling (600 MHz)
Level V test equipment or better is required to test class FA cabling (1000 MHz)

Patch Cables – The Good, The Bad and The Ugly.



I have been in the Datacom/Telecommunications industry for over 20 years now and I can hardly believe how fast the time has flown by. When I first started at Datcom I was working in the production area making both fiber and copper cable assemblies. So I know quite a bit about the history and evolution of connectivity.
 Much has changed since then and many of the cables we made are no longer used and have been replaced by the most common of cables the humble Ethernet patch cord.
 Despite its appearance a lot of R&D has gone into its components and specifications over the years. Soon these cables and components will be adjusted again to support the emerging Cat8 cabling standard. But despite this change there is one thing I know should never change and that is quality.
 Certainly I understand that our economy is now global and that our industry is now hyper-competitive; however when it comes to connectivity quality matters. Too many times I have spoken with clients who chose to go with the lowest price when it comes to installs and cable assemblies and I would say that 90% of the time they end up spending more money in the long run replacing products that just don’t meet operational specifications.
 This issue has been well documented in our industry and we now have an industry watch dog in the CCCA which is helping us be informed when it comes to fake or substandard products in the market place. This article on patch cables is one example:
 Testing by CCCA Finds High Failure Rate in Electrical Performance of Imported Category 6 Copper Patch Cords - See more at: http://cccassoc.org/news/press-releases/testing-ccca-finds-high-failure-rate-electrical-performance-imported-category-6-copper-patch-cords
For this reason I felt compelled to give my customers and others a dissection of what makes a patch cable good and what to look for when buying products. The points below high light what would be considered bad and the linked photos show what would be good.
 1) There is no mfg name on the jacket. (Bad)
  2) There is no UL or CSA mentioned on the jacket. (Bad)
 3) There is no TIA standard listed on the jacket. (Bad)
 4) There is no mfg name on the components. (Bad)
 5) The connector looks to like C5 not C6. (Bad)
  6) Connector does not have an insert or technology designed to reduce cross talk. (Bad)
 7) The jacket material itself, especially within the connector looks either kinked or twisted (Bad)
 8) The actual lack of twists in the conductors in the upper portion of the connector looks to long as defined by the standard. (Bad)
9) The plating on the pins looks a little tarnished. (Bad)
10) The front view of the conductors also looks like the cable may be Copper Clad Aluminum. (Bad)
  And last but not least the ugly.
