Network Cabling Systems

Voice and Data Cabling - Network cabling carries the lifeblood of your organization - information. To minimize expensive data network problems and to add value to your business, River Valley Communications follows strict installation and testing guidelines adhering to EIA/TIA and BICSI.

Coax Cabling - A critical piece of the infrastructure puzzle for our legacy customers. Coax has been the medium of choice for high fidelity audio, television, satellite and broadband communications and is till used widely even though in most arena's they have been replaced by modern solutions.

Video Cabling
- Video cabling can be closely associated with coaxial cable, because most video applications require
coax, but we also install twisted pair cable for certain video applications based on the complexity at site and requirements.

Twisted Pair Cabling
– Unshielded Twisted Pair has been designed for use in voice applications and local area networks. Because of the relatively low cost, this cable is widely used and is available in several different performance categories adhering to EIA/TIA standards.

Fiber Optic Cabling
- We install, terminate and test multi-mode and single-mode fiber. We've kept abreast of
advances in the manufacture, termination and testing standards of fiber optic cabling systems and use advanced splicing techniques for our installations.

Data Center Cabling
- Because the server room is the centralized brain of your structured cabling system, we take special care to design and install it according to the highest standards. We are the leading industry solutions provider in the DATA Centre arena and have wide levels of experience and expertise to understand customers needs and to put them to work.

Network Cabling Systems - Fiber Optic Cabling

Your Fiber Specialist - With more than 15 years of experience on fiber from when it all started

Fiber Optic cabling provides a far greater bandwidth than copper and is typically used for backbone connection between localized networking equipment and is increasingly becoming the preferred choice for high quality and reliable analog and digital communications.

Although its higher cost can be prohibitive for desktop applications, fiber optic cabling provides a high security link, with immunity from electromagnetic interference (EMI). It is also the solution for inter-building links and other connections beyond the maximum 90m for Category 5e, Category 6 and Category 7 copper cabling.

Fiber Optic Cable Design & Installation
River Valley Communications carries out the design, installation, testing & maintenance of Fiber Optic systems including Fusion Splicing & Termination of multimode & singlemode fiber cables, including repair work. The same applies to Indoor as well as Outoor Fiber Installations.

All types of fiber optic cabling systems are offered including:

Multimode 62.5/125 (OM1) Datacommunications
Multimode 50/125 (OM2) Video & Datacommunications Systems
Multimode 50/125 (OM3) Gigabit Ethernet an 10 Gig Ethernet for up to 300m
Singlemode 8/125 (OS1) Gigabit Ethernet and 10 Gig Ethernet for up to 2km.
All cables are internal/external grade.

Fiber Optic Termination & Testing
Our Fiber Optic termination and testing service is offered to corporate end users as well as other communication providers who prefer to use our skilled services rather than invest in expensive test equipment and costly engineer training. Both methods of termination are offered either direct termination or fusion splicing of pre-manufactured pigtail assemblies.

Fiber Optic Advantages

Increased Bandwidth
A fiber optic system may have very high bandwidth, sometimes operating at data rates of 10Gb/s, equivalent to more than 120,000 standard telephone calls over one pair of optical fibers (one transmitting and one receiving).

Under Lab conditions, data rates as high as 10 terabits per second have been demonstrated (150 million telephone calls).

Datacommunications type fibers have a lower information carrying capacity but are capable of 1Gb/s with some 10 Gigabit systems now in use.

Increased Distances
Due to the low attenuation (or signal loss) exhibited by optical fibers, signals can be transmitted through very long distances. In subsea or under water telecommunications, distances of up to 280km have been used without the requirement for repeaters or boosters. Repeatered systems can span as much as 10,000 to 15,000km, where optical amplifiers are used to boost the signal levels typically around every 80km or so.

Datacommications optical fibers have higher losses but can easily cope with the longest cable runs likely to be encountered in LANS.

Lightweight and Compact
An optical fiber is extremely light, a 2km bobbin would only weigh approx. 0.5 Kg, therefore it is ideal for use in applications where weight is critical. Equally, a coated optical fiber is only 250 microns (a quarter of a millimeter) in diameter; a 12 core (12 fiber) cable may be less than 8mm in diameter for indoor use.

Fiber Optic Cabling Is Secure
Operational fibers do not radiate any signal, the optical signal is completely contained in the middle of the fiber. This means that fibers are frequently used for applications where data security is important such as military and government communications. Even if attempts are made to ‘tap into’ a fiber optic cable by isolating a bare fiber and putting a tight bend onto it so that some of the signal escapes, this intrusion can be detected by monitoring the power of the transmitted signal, and located using an OTDR technique (Optical Time Domain Reflectometry).

Fiber Optic Cabling Is Safe
A fiber optic communications cable does not need to carry any electrical current. It is possible to construct completely non-metallic cables so that full electrical isolation can be achieved, particularly important in the Electric supply industry. There are no risks of short circuits generating sparks which may ignite explosive gases etc.

Non-metallic cables are not prone to lightning strikes in exposed areas.

All these intrinsically safe characteristics have led to the widespread use of fiber optics in hazardous environments such as oil refineries, chemical works, coal mines, etc.

Fiber Optic Cabling Is Environmentally Friendly
When compared to copper communications cables, there is little use of resource in manufacturing, transporting and installing fiber optic cables because of the lightweight, compact nature of optical fibers.

Fiber Optic Cable Has No Scrap Value
Fiber optic cable is worthless as scrap and therefore not worth stealing unlike copper telecoms cable.

Fiber Optic Cabling Is Future-proof
Any fiber optic system currently installed will only be using a very small fraction of the potential information carrying capacity of the fiber. Therefore, as demand for communications capacity increases the system can be upgraded by attaching more sophisticated transmission equipment.

Fiber Optics Are Cost Effective
Many people view fiber optics as being very expensive, but for any application where there is a lot of data to move over long distances then fiber is likely to provide the cheapest solution.

There is a general downward trend in prices of fiber optics cabling, components, tools and installation equipment. However, the transmission equipment which converts electricity into light and back again is still relatively expensive. As prices continue to fall, and the price of copper continues to rise, fiber optics will become the most cost-effective solution for more and more applications – bringing all the other benefits as well.

The only disadvantage on fiber would be that it required skilled engineers and expensive tools for installing and indepth knowledge for testing the systems. An installation done without proper expertise would not be able to provide you the best of results and lead to revenue leakage.
