Fibre Optic Cable Networks
Turnkey Optical Outside Plant Networks
We have an extensive track record and tried and tested operational capabilities to design, install and maintain fibre optic cable networks. We have particular expertise in long haul optical cable infrastructure often referred to as Out Side Plant (OSP).
We can design and install all elements of a physical optical network including the construction of dark fiber routes to the activation of the network.
We have successfully completed hundreds of large scale OSP projects, including but not limited to:
- Multimode and Singlemode
- Long Haul Networks
- Metro Networks
- Campus Based Networks
- Access Networks.
Our Management Team has OSP expertise that spans more than a century and a half, with an average experience of our field engineering personnel of more than 13 years.
Our OSP services cover the following activities:
Project Life Cycle Capabilities
Fibre Characterisation Services – Wavelength Division Multiplexing
The competition to build higher speed optical transmission systems and to exploit the latent bandwidth within an optical network is increasing the requirements to support both Coarse Wavelength Division Multiplexing (CWDM) and Dense Wavelength Division Multiplexing (DWDM) transmission solutions. The requirements are now becoming standard practise in both long haul and metro networks.
Telecommunication network operators and service providers understand the need for a detailed analysis of their fibre cable plant to determine its ability to allow network migration to 10Gbps, 40Gbps or even 100 Gbps systems. Our Characterisation Service helps clients to understand their optical network capabilities and optimise the performance of their fiber networks by identifying the ‘optical fingerprint’ of each fiber.
Our Fibre Characterisation Service will evaluate each fibre and provide a comprehensive final report with detailed test results and recommendations, documenting; Insertion Loss Measurement (IL), Optical Return Loss (ORL), Optical Time Domain Reflectometer (OTDR) traces, Chromatic Dispersion (CD), Polarisation Mode Dispersion (PMD) and Attenuation Profile (AP), for each fibre tested.
Our engineers will assess the health of your fibre optic network, and provide you with invaluable data to allow you to determine your immediate and future network upgrade path.
Blown Fibre Solutions
Air Blown Fibre was conceived by British Telecom with the objective to establish a fibre cabling system that once installed, could then be upgraded, extended and even replaced without the expense of re-laying cable, disturbing the fabric of a building or digging-up the roads. The technology is a versatile and truly future proof for many application areas, such as fibre to the desk / home, Backbone, Horizontal, Campus, Access, Metro and Data Centre applications.
Benefits of Air Blown Fibre Solutions are:
- For Integrators, the clear advantage of blown fibre is that it reduces the number of optical fibre splices in a network. Thus, optical attenuation losses are significantly reduced.
- In a new build, the protected microducts can be installed early on in a project and the blown fibre introduced once the building project has progressed
- For the owner of a network or a commercial premise, the advantages of blown fibre are very tangible when the potential savings are considered against the whole lifecycle and associated costs of both premises cabling and conventional sheathed cable systems.
Passive Optical Networks (PON)
A Passive Optical Network (PON) is a point-to-multipoint optical access solution. Its main characteristic is the use of passive optical splitters in the fiber distribution network, enabling one single feeding fiber from the provider’s central office to serve multiple homes and small businesses.
Passive Optical Networks use passive components and architectures. PONs are called passive because, other than at the CO and subscriber endpoints, there are no active electronics within the access network. PONs use point to multipoint physical topology and their shared infrastructure result in lower cost per customer. PONs are based on ITU-T’s recommendation G.982. This recommendation generally addresses all types of PONs; however, GPONs are based on G.984.
A PON is associated with a single Optical Line Terminal (known as an OLT), which is usually placed at the Central Office or POP and Optical Network Units typically equal to the number of subscribers. These ONUs are placed inside or outside premises depending upon fiber termination configuration used in that setup. ONU’s provide several user interfaces to cater for multiservice needs, which include communication, entertainment, information and others.
