6 Major Factors Affecting Fibre Optic Cabling Performance

Fiber-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 Fiber Optic Cabling. Here are some of the key factors affecting the performance of fiber optic installations.

  • Incorrect specification of fibre optic cabling  Fibre 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 installation

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

Data Cabling — Hiding your AV Equipment

IT Cabling — Residential Audio Visual Installations

“To See or Not to See”

Is it a Mirror? Is it a TV? Is it Both?

On every Residential AV Installation you have the decision to make of how much equipment do I have and where to have your equipment.

Equipment such as Sky Boxes, DVD Players, Speakers ,Amplifiers, Music Servers, Movie Servers, and a whole lot more.

The standard method is a Television in each room with a Sky box and DVD linked directly to the television. On a stand this looks fine but with handing a flat screen TV do you still have an unsightly furniture piece under it and take away the effect of the flat screen. If there is to be no furniture where does all the equipment go? Also what if you have more than 3 televisions and Sky will only give you 3 boxes?

Then to speakers, do you have visible round speakers in your ceiling messing with your lighting design, do you have speakers on your wall, do you like the sight of them visible or not?

Some clever solutions we utilise to hide your AV equipment with great effect.

Picture Frame Televisions


Mirror TV installation — Is it a Television, a mirror, a family picture frame, an Aquarium? The choice is yours

Stealth Speakers


These speakers install flush with your walls.They are then painted with the wall so they disappear

Central Control System

Put all your Sky boxes, DVD players, Music and Movie servers all in a central location and cable to each location. All your equipment fully hidden, useable by all locations and fully functional

Then onto control. Do you have a separate control for everything you own or do you combine, can you control your house from one place or must you have separate control for each area.

Designing and Allocating Space for Communication Rooms- Cabling Solutions

Communication Room Design
When designing a communications room the space required needs to take into consideration, the current requirements and expected overall requirements should the tenant space have the ability to add additional data cabling solutions outlets in the future?

ANSI/TIA-569-D provides the outline for these spaces and the allowances that best practise should allow for.

Communication Room Size
The communications room should be built to provide enough space and cabinets for the largest amount of expected data outlets that the communications room will service. For example if the tenant space could potentially have 500 employees and 1200 data outlets the space should be built for that allocations even if 400 staff and only 1000 outlets are first installed.

General Requirements for Communication Room Design
The following general considerations for communication room design allow the room functional use, the ability to take and remove equipment and the flexibility of mounting equipment-
• Only equipment relevant to the communications room should be present in the room. No services for the rest of the tenant space should pass through the communications room
• Ceiling height should be a minimum of 2400mm with no obstructions. 3000m minimum is recommended to allow for overhead containment
• Overhead Containment should have a minimum of 200mm clearance from the finished ceiling
• Floor consideration (solid, tile) should be designed for the expected current and future floor loadings
• Access door should be a minimum of 900m wide and 2000m high. The door should hinge outwards. A double door 1800 wide and
• 2300mm high is recommended if large equipment is anticipated
• No external windows are recommended
• Allowance of 19mm fire retardant painted plywood to cover at least one communication room wall.
• Fire protection as per main building plan and code to apply

Mechanical and Electrical Requirements
• Lighting should be a minimum of 500 lux in horizontal plane and 200 lux in vertical plane. (measured 1m above finished floor level)
• Minimum of 2 dedicated un-switched power sockets on a dedicated circuit separate to the rest of the building sockets
• A dedicated cleaners socket should be installed to avoid the use of the cabinet power sockets
• Temperature range must be 18–27 Celsius (64–81F)
• Minimum dew point must be 5.5 Celsius (42F)
• Maximum dew point must be 15 Celsius (59F)
• Maximum relative humidity must be 60%
• The temperature and humidity are as the ASHRAE Class B standards

Data Cabinet Requirements
• A maximum cabinet height of 2100mm is recommended for installing and accessing top racked equipment
• Cabinets should be planned for future and present equipment to be installed. Depth is the main consideration and a minimum of
• 150mm space should be allowed for over the deepest equipment to be installed
• Cabinets should have front and rear rails and be recessed a minimum of 100mm to allow for cable management and patching
• PDU (power distribution units) should be installed in all cabinets containing active equipment. They should not be switched to avoid accidental switch off
• Cabinet clearances should be as follows
• 1000mm clearance at the front of the rack (1200mm preferred)
• 600mm clearance at the rear of the rack (1000mm preferred)
• Cabinet feet can either be solid feet or wheels. Wheels must be lockable if installed

Other General Considerations
The communication room should be a dedicated room for network cabling technology equipment and services for the network throughout the tenant space. The following considerations should be considered as general advice-
• Communications room should be a restricted access area by code / key or access control
• Sign in and sign out is recommended for troubleshooting should a failure occur
• The room should not be used for general storage
• The room should not be used as a general office area.
• When working in the room the door should be left open due to the presence of recirculated cooled air

What is a Fiber Optic Cable and What are Types of Fiber Optic Cables

A fiber optic cable defined in IEEE 802.8 is cable that contains optical fibers (usually glass) coated in plastic that are used to send data by pulses of light or in general term afiber optic cable is a cable that carries information in the form of light through optical fibers. In a cable, there can be a single or multiple strand of optical fiber. Optical fiber is internally made of glass and covered with plastic.

Other types of fibers use electricity to carry data or information, whereas fiber optic cable uses light to transmit the data, due to which the data transfer capacity is far better than the tradition cables. As the outer layer of the fiber optic cable is covered with a protective material the electromagnetic interference is least. Fiber optic cable also have the bandwidth higher than other cables. Hence they are designed and used for long distance, very high performance data networking and telecommunications.

Different types of optic fiber cables are used for different types of application. Sometimes the signals need to be traveled a longer distance, sometimes for shorter distance but with higher speed or sometimes with minimal loss, etc. For all these different conditions, different types of optical fiber cables are used.


Innermost part of the optical fiber is called as core and the cover of it is called as cladding. They both have different refractive index which results in the total internal reflection of light with minimal losses and helps to transferred the signal as required. In most of the fibers, the cladding is coated with a layer of acrylate polymer or polyimide. Above that many different layers of protective sheathing are provided depending on the application.

Each end of the optical fiber relates to a special fiber connecter, so that it can be easily connected and disconnected from transmitting or receiving device. The lights are generated with the use of LEDs (Light Emitting Diodes), lasers or injection-laser diode (ILD), which on transmitting through optical fiber at anangle based on the refractive index travel through it.

Types of Optical Fibers:

Optical Fiber are broadly classified into following two types:

  • Single Mode Optical Fiber:

In this type of Optical Fiber, a single stand of glass fiber is used which has a diameter of 8.3 to 10 microns. It carries higher bandwidth than multi mode fiber, but it requires a light source like laser or ILD with a narrow spectral width. It uses the Wave Division Multiplexing (WDM) techniques so that the amount of data traffic that needs to be sent across the strand can be increased.

It is also called as mono-mode optical fiber,uni-mode fiber, single-mode optical waveguide.

  • Multi-Mode Optical Fiber:

Optical diameter of Multi-Mode optical fiber is larger than the single mode fiber. Multi mode fibers provide a higher bandwidth and hence the data transfers at higher speed. Normally LEDs are used as the source of light to transmit the signal.

Fiber optics cables were not available until 1970 and in 1977 it was the very first time when optical fiber was commercially used. After that the use of optical fiber has increased with a rapid rate and todays digital world, all are moving to optical fiber.

Fiber Optic Cable Precautions:

Following are few precautions that needs to be taken into consideration while using optical fiber.

  • Optical fiber connections and connectors should be capped when not in use so that it can be prevented from dust, dirt or other substances.
  • Fiber optical cabling should not be bend more than the diameter of the hand. Bending the optical cable more than that could cause physical damage to the cable.
  • The tip of the actual fiber cabling should not be touched.
  • A meter needs to be used to determine that the signal or pulse is being transferred or not.

Fixed Testing of Electrical Systems 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:


  • 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….Read More….evidence of fixed testing

How To Recognise A Pro SEO Company From An Inferior One

Search Engine Optimization (SEO) is important for companies who want high traffic and rankings for their website.  It is a web marketing strategy. Each company website is different and if taking up SEO, should have the SEO tailored to the company’s industry and needs.


The SEO company should have at least a few years of experience. With a few years of experience, they would have at least done SEOs for a multiple of industries. The SEO Company should have ready, portfolios to show you what they have done for customers previously. With experience comes knowledge as well. If an SEO company has had quite a number of years of experience, they would be better to advice customers on how to go about deciding on things. E.g. The right keywords and topics. Also, ask them to tell you stories. Ask more about the company to get a clearer image, their past clients, how they handle difficult clients and etc.



Proposals –

Get proposals from SEO companies you are interested in. There a few things to look out for before or when getting a proposal.

They ask many questions

Make sure the company asks you a decent amount of questions because this shows their sincerity in doing up a proposal for you. The questions that they ask should not be just about SEO activity but also more on your company, from how it runs, how the company makes money and also where opportunities would come.

Plan is created uniquely

Make sure the SEO Company coming up with your proposal does not use a template to do so. It would be excellent if they look at your company’s strengths and weaknesses before doing up a plan. Finding more about your company takes time but it also means that they will take time coming up with a unique proposal for you.

If the company comes up with a proposal fairly quickly without much communication with you or questions, they probably followed a template to come up with the proposal.

They show portfolios

Not many companies will readily show you their client list and the work they have done for them unless being asked for it. Ask for them to show you their portfolios so you get a better understanding on how they do their planning and also how they execute their plans. Bonus points to companies that show you their portfolios without having you to request for them.

Ask questions –

Make sure to always ask as many questions as possible when in doubt. Some of the questions you can ask are for their opinions on SEO, the future of online marketing and also some of their references.

Do not go for SEO companies who have bad service those who have bad reviews. It will just be a waste of time for you. So make sure to do substantial research and only hire an SEO company when you have absolutely no doubts that the SEO Company is the right one for you.

From these advices, we hope you will find a professional SEO Singapore Company!
