Data Communication Services
We provide an array of voice and data services from the supply and installation of cabling, network switches, telephone systems and cable management.
Structured Cabling
Cat 5 Network Cabling Contractors are critical to the success of you network operation.
Cat 5 cabling contractors and installers RawApple ©ommunications are experienced in copper
cabling installations. Cat 5 cabling and Cat 5e cabling contractors are quite common but we would argue
that few are as capable of delivering a cat 5 cabling installation as quickly and efficiently as
RawApple ©ommunications! Copper cabling and in particular Cat 5 is in widespread use and for many
applications, departmental networks or for small business applications Cat 5 is the cabling solution of choice.
By choosing a reliable Cat 5 cabling contractors such as RawApple ©ommunications you can be assured of a
good value for money network that is installed on time and on budget.
Cat 6 cabling contractors RawApple ©ommunications can take your copper network installation
to a new level with our advanced Cat 6 cabling installation service. RawApple ©ommunications
will help you plan and implement your Cat 6 Cabling Network. With wide experience as cabling
contractors in all types of cabling including Cat 6 Networks RawApple ©ommunications will ensure
that your network cabling installation is a stress free process from planning right though to the
installation of the cabling.
Fibre Cabling
Fibre optic technology uses glass fibres to transmit data and voice. A fibre optic cable consists
of a bundle of glass fibres, each of which is capable of transmitting messages modulated into
light waves. Coupled with laser technology and state-of-the-art electronics, fibre optic cable can
transmit and receive vast amounts of data far in excess of traditional copper cables such as Cat5, Cat6 and Cat7.
Types of fibre optic cables
There are in the main two types of fibre optic cabling, single-mode and multimode.
The rise of 10Gigabit Ethernet has sparked a new wave of arguments within the fibre optics industry, and
as a result a new breed of standards has been introduced.
Four levels have been decided - OM1, OM2, OM3 and OS1. OM refers to optical multimode, while OS refers to optical singlemode.
Single-mode
Single-mode fibre cable allows only one mode (or wavelength) of light to propagate through the fibre.
It is capable of higher bandwidth and greater distances than multimode, and it is often used long for
distance connectivity. This type of fibre uses lasers as the light-generating method. Its maximum cable
length is more than 10 km.
Multimode
Multimode fibre cable allows multiple modes of light to propagate through the fibre. It is used for
workgroup applications and intra-building applications such as risers. It uses light-emitting diodes
as a light-generating device. The maximum cable length is 2 km.
Fibre optic technology is safe, secure and cost-effective. It has the highest level of reliability and
redundancy for transmitting audio, video and data information. The broad bandwidth provided by
fibre optics makes it the technology of tomorrow.
Fibre optics has several advantages over traditional copper cables:fibre optic cables have a much
greater bandwidth than copper cables. This means that they can carry more information.
fibre optic cables are less susceptible than copper cables to EMI and EMC interference, allowing
you to lay it where you need it, without having to worry about the proximity to electrical systems.
The transmission distance of copper cabling is 100 metres, compare this to 10km and 2km for single
and multimode fibre optics. Fibre optic cables are much thinner and lighter than copper cables. Data
can be transmitted digitally (the natural form for computer data) rather than analogically.
Where information security is the prime concern fibre optic is the only cabling technology guaranteed
to be immune from unauthorised eavesdropping.
RawApple Communications is highly experienced in the provision of fibre optic cable installation.
We offer complete design, installation testing and commissioning services with national coverage.
All fibre installations are tailored to individual’s current network requirements with expansion and
future proofing built in to the overall design.We offer a fibre optic termination and testing service to
corporate end users as well as partnering with other communication providers who prefer to use our
skilled services rather than invest in expensive test equipment and costly engineer training.Our
termination methods are fusion splicing of pre manufactured pigtail assemblies.
All fibre testing is carried out with our own calibrated test equipment with either stabilised light
source and power meters or optical time domain reflectometers (OTDR) for performance.
Fibre Optical backbone installations
We supply and install all types of communications optical fibre, whether it is single or multi modebackbone cabling systems. We can terminate fiber by using any specified ends .i.e. ST, SC LC etc.
to suit your infrastructure. All terminations are carried out by fusion splicing factory made and tested
pigtails which ensure low budget and db loss. All our installations are tested and the test results
supplied to you after the installations are complete.
We use state of the art technology, our splicing and testing equipment is of the highest standard and is
maintained and calibrated regularly. We supply any type of fiber cable or patch leads to suite your
requirements or specifications.
We specialise in fault finding and locating breaks in fibre cables. All of our fibre technicians are
specifically trained in fibre installations, maintenance and fault finding.
