Specialist skills are required for the installation of fiber optics, especially in the terminating and testing phase. ComKraft Telecom are specialist in this field; trained with the specialist skills required.
Cost of installation
Although prices are reducing all the time for much of the equipment, the cost are still higher than for copper cabling installations.
Cost of transmission equipment.
The cost of converting an electrical signal into an optical signal for transmission down a fiber, and the added cost of converting it back into an electrical signal is much more expensive than sending an electrical signal down a copper cable.
Fibers cannot carry power
Electrical power cannot be carried along a fiber. This has important implications for fiber to the subscriber , where at the moment the electricity needed to make the telephone work is provided down the wire from the exchange.
Vulnerable
Because of the enormous information carrying capacity of fiber, there is a tendency to ‘put all your eggs in one basket’. This means that a fiber fault can result in catastrophic loss of communications. Fibers are often though of as being very fragile, however they are in fact surprisingly strong, particularly under tension.
