Network cabling infrastructure is the backbone of communications within your organisation. Without network cabling, you couldn’t use the telephone, internet/intranet or email, and database networks wouldn’t be possible. That’s why it’s Important to install a quality structured cabling system. Upgrading or investing in your network cabling will enhance your company’s ability to communicate. Improving communications has many tangible benefits which will save your organisation time and money. As well as enhancing working practices and procedures. A faster, more reliable computer network will increase productivity and reduce down-time. A custom-designed system will give you more flexibility. You’ll save time and money on maintaining and repairing dating equipment. You can make your organisation future-proof, to adopt new technology, expand and grow.


Merc Systems SA offers structured cabling services throughout Southern Africa. This includes the design, installation, maintenance and repair of data cabling and voice systems. Our services are bespoke, catering to your individual needs. We’ve worked in a diverse range of sectors, helping organisations to enhance their communications infrastructure for a more efficient future. We guarantee that we are one of the best structured cabling companies Mpumalanga has to offer! A fundamental decision in the design or upgrade of your network is the type or standard of cable to be installed. We are certified to install, test, maintain and repair the following cabling systems:


Copper cabling is defined by "category". This is a classification system based on the rate at which data can be transferred across. Category 3 / cat3 – Basic voice cabling for interconnectivity between telecom points (also known as multipair cable). Category 5e / cat5e - LAN support up to Gigabit Ethernet at 100Mhz. Category 6 / cat6 - Lan support up to Gigabit Ethernet at 250 Mhz. 10 Gigabit Ethernet is supported but only up to 55m. Category 6a / cat6a - Developed to support 10 Gigabit Ethernet, data can travel up to 100m which is twice as far as Cat 6 cable.


Supports Gigabit Ethernet, and 10 Gigabit Ethernet backbone technology. There are two types of fibre optic cables; multimode and singlemode. The first carries multiple signals, and the latter transmits a sole light signal. Single is used to get higher bandwidths over longer distances. For longer cable runs we recommend fibre optics.
