Why you should insist on Structured Cabling Testing and what you should insist on

Structured Cabling Testing – Reasons to have your installation tested

  • If it’s not tested you won’t know if the installer has
    1. Terminated the data cabling correctly end to end
    2. Terminated the network cabling correctly in the right methods
    3. Terminated the structured cabling to the correct standards
  • Not all cabling terminations are equal. Poor terminations can result in the following
    1. Slower network speeds (i.e. only running at 100MB instead of 1 Gb)
    2. Interference on the data cable
    3. Interference onto neighbouring data cables
    4. Drop outs (i.e. phone calls drop or lost connection to servers)
  • Structured Cabling Testing checks that the correct patch panel ports go to the correct data module location. If the system isn’t tested this issue won’t be highlighted by the data cabling installer to rectify. Your system is then unusable from a management perspective
  • You have accountability! If you receive test results, it shows at a point in time that everything was installed correctly and working to the specified standard. This eliminates the blame culture later on
  • Testing checks that all the elements of the installation have been installed correctly
    1. Data cabling has been pulled in correctly, away from power, without and kinks and twists
    2. The minimum of exposed cable has been allowed for when terminating
    3. The cable is terminated in the correct format
    4. The modules are good and snugly fitting
    5. Without these steps done correctly the structured cabling link won’t pass
  • Structured Cabling Testing shows that the materials used are to standard as well as the data cabling installation. Poor modules, panels and cable will fail every time regardless so the quality of installation


What you should insist on from your Data Cabling Test Results

  1. That Structured Cabling Testing is done with Data Cabling Cable Analyser and not a cheaper mod tap tester


Structured Cabling Testing test sheet

Without 1 of these test results PER CABLE you are taking a risk that your data cabling installation is not fit for purpose.

Public Wifi for Covent Garden


NM Cabling in association with Digital Avenue have been tasked and completed the WIFI cabling for  Covent Garden Piazza in London.

The Wifi and cabling will be used for public cloud access throughout Covent Garden the popular London tourist location.  WIFI cabling at Covent Garden Piazza

The Covent Garden Wifi data cabling was required to be run externally and completed out of hours to minimise disruption.

The Wifi cabling had to be run between 11pm and 7am, externally on powered access platforms amongst the piazza buildings.

As an additional challenge the structured cabling for Covent Garden Wifi had to be installed while 7 other platforms were simultaneously installing the plaza Christmas lights.

Communications Room Data Cabinet


Comms room data cabinet Potential problems

A comms room cabinet, such as the above, is a regular sight we come across in the data cabling world. Quickly patching in that new network port with whatever colour, length or quality of patch cable to hand is certainly quick, but is it a recipe for disaster to your IT network.

Below we list some potential problems that you can encounter, if your comms room cabinet is looking like this or worse:

Potential problems from this haphazard patching system are;

  • Somewhere amongst all that mess of cabling is your incoming ISP / broadband line. One snag/tangle which causes the wrong lead to break or pull out, could take down your entire office.
  • If you have separate networks, there’s a very real DANGER that one stray cable can link 2 networks together allowing full access. (We have seen this in a school before, where the admin and pupil networks became linked and this led to the pupils having full access to all files, folders and un-restricted websites)
  • The situation can only get WORSE! Anyone adding to this system are only going to add to what’s there, rather than put everything new in nice and neat. It’s only a matter of time before one more is too many!
  • You’re WASTING MONEY on buying additional expensive hardware when it’s not needed. When the patching is this messy, you can’t see what ports on your switches are actually active and used; therefore when they are all full up you have to buy another expensive switch. If your patching was up to date the unused ports would be visible and these could be maximised.
  • They can become a FIRE hazard! Usually a comms room cabinet like this will go hand in hand with a power system of extension leads and multi block power leads. Extension leads plugged into extension leads in a cabinet are a high fire risk. Better to have full size cabinet PDU’s for all of your equipment.
  • Having a multitude of patch leads running across the front of a cabinet, does NOT allow the heat created by your active equipment to disperse. This can SHORTEN the lifetime of this networking equipment by causing OVERHEATING!
  • It’s costing you DOWNTIME! When a phone, WIFI, PC or any hardware goes down, instead of quickly being able to troubleshoot the situation; additional time is required to trace where ports go and where the source of the problem is.
  • It’s COSTING your people TIME and you MONEY! With a fully organised cabinet, Adds/Moves and Changes are almost instantly SAVING your IT technician or Support Company TIME and you MONEY.

Fixed testing in the Workplace


Checking the condition of your electrical systems on a regular basis is vital for detecting and preventing potential hazards.

Fixed testing, also known as Electrical Installation Condition Reporting or periodic inspection, is a systematic test of all of the various elements of your electrical services, including cabling, switches, lighting and outlet points.


Regulation and Responsibility

In the UK, workplace electrical installation maintenance is covered by several regulations including:Fixed testing in the Workplace

  • 1974 – Health & Safety at Work Act
  • 1989 – Electricity at Work Regulations
  • 1992 – Workplace (Health, Safety and Welfare) Regulations
  • 1999 – Management of Health & Safety at Work Regulations


The Electricity at Work regulation specifically states that “all systems shall be maintained so as to prevent, so far as is reasonably practicable, such danger.”

Companies have a responsibility to their employees and the general public, to look after their health and safety while they are on site. That being said, the 1989 Electricity at Work regulations also recognise that employees must be co-operative in helping to prevent health and safety issues.

Beyond the official regulations, evidence of fixed testing may also be a requirement from your landlord, mortgage provider or insurer.


Testing Frequency

How frequently your electrical systems need to be checked varies depending on the type of equipment you have installed, how often it is used and who it is used by. Typically locations using high powered electrical machinery, or where the public is in close proximity to the technology, will require more rigorous and frequent checks.


In most normal settings it is recommended that a routine check is carried out annually, with formal inspections every five years, or whenever you move into a new property. These time-frames would be suitable for a typical office IT electrical installation.

One notable exception to this is fire alarms, which should be checked weekly, with a formal test at least once a year.

It goes without saying that fixed testing must be carried out by a registered electrician.


Minimising disruption

While this type of testing can seem invasive, Guidance Note 3 of IEE Wiring regulations states that tests should be conducted “in such a way as to minimise disturbance of the installation and inconvenience to the user”. This includes agreeing a convenient time to conduct the tests.

Precautions are also taken to ensure that no equipment is damaged during the tests.

Although every effort is made to minimise disruption, inevitably this requires careful scheduling and may require working out of hours.

On completion of the tests you will be issued with an Electrical Installation Condition Report, which details the results, including defects or dangerous conditions that will need to be immediately rectified.


Don’t leave it too late

With the influx of technology and computing into the workplace over the past decade, IT electrical installation has become a vital part of the office environment and the life blood of many companies. Failing to regularly check the condition of your systems not only puts your business at risk, but exposes your employees to unnecessary danger.

Dangers and Correct Usage of Extension Leads

The right and wrong way to use them in your office


Electrical Installations –  wall sockets, floor boxes  and extension leads are part of a standard office setup. However when is it a good idea to use an extension lead and when is it not. What are the correct safety procedures? What are the dangers?

Some problems that can be experienced with extension leads can be as follows

  • If an extension lead is not contained within desks and laying across access routes they can cause a dangerous trip hazard
  • If being continually walked on and pulled by catching chairs and feet then the cable may become damaged, the cable sheath damaged and exposure to electrical shock
  • Plugging one extension lead into another to create more sockets can cause the current to be exceeded and cause a possibly fire hazard
  • Using an extension lead in the coiled position can cause a fire hazard

Best practice when installing extension leads

  • Use manufacturer assembled extension leads and plug one lead into a dedicated socket or floor box.
  • Use surge protected extension leads
  • Use the correct rated extension lead for your application and equipment used
  • Install the extension lead so none of the lead is on the floor or exposed to tripping, catching or damaged (i.e. via containment in desks, cable spines from floor boxes)
  • Install additional wall / floor electrical sockets if you are overloading your existing sockets with large extension leads or joining them together

If you have any concerns with your electrical installation please call for free advice or a survey on 01923 888588 or

6 Major Factors Affecting Fibre Optic Cabling Performance

Fibre-optic cable has an amazing bandwidth and is often restricted by the hardware
either side of the cable rather than the bandwidth of the cable itself. However, performance can be affected by the installation of the Fibre Optic Cabling. Here are some of the key factors affecting the performance of fibre optic installations.

  • Incorrect specification of fibre optic cablingFibre Optic Cabling London - Fibre Optic Cabling - Fibre Optic London


If the speed you wish your network to run on doesn’t have the correct fibre optic cabling installed, it will never run at the desired speed. For example for 10Gig speeds the maximum cable length you can run ranges from OM1 (33metres), OM2 (82metres), OM3 (300metres) OM4 (400metres). Exceed this distances or pick the wrong fibre optic cable and your network will slowly


  • Poor connector terminations


If the fibre optic cabling connector ends are poorly terminated or the ends bent too sharply then the light passing through will either be limited or at too low a range for the transmission to be connected. With fusion splicing and correct terminations, standard optical fibre cabling speeds can be guaranteed.


  • Dirty connector ends


If the fibre optic cabling connector ends become dirty then the transmission can be intermittent or not work at all. Keeping the unused optical fibre cabling connectors covered when not in use goes a long way to alleviating this problem


  • Poor installationFibre Optic London -Fibre Optic Cabling London - Fibre Optic Cabling -


Fibre optic cabling has a specific bend radius and pulling tension guideline when installing the main cabling runs. If the cable becomes stretched or bent too tightly then the quality of light down the cable is compromised resulting in a poor or non-existent performance.


  • Patch Leads


With regular patching and un-patching the patch leads can become scratched or dirty. The weakest part of the link creates the overall quality of the link as a whole, which means a poor patch lead can create a poor link overall. Fibre optic patch leads should be cleaned each time they are re-patched


  • Crossed over patch leads


More of a cause of no performance than poor performance the biggest reason a fibre optic link doesn’t work after installation is the patch leads are not patched for the correct fibre optic cabling link. The first place to check when a link doesn’t come up is by swapping around the patch lead cores and testing the link
