The two principal advantages of pre-terminated cabling are reduced time on site and improved quality of terminations.
Pre-connectorised, or pre-terminated, cabling are most popular when time on site is at an absolute premium. This may be in a new build, such as a data centre, where time scales are critical and many different trades are vying for the right to work on any particular bit of floor space.
Related to the ‘less time on site’ issue is the fact that less people are required on site. In a dense cabling installation, such as a data centre, it may be impractical to expect a large number of cable installers and all their specialist optical termination equipment to fit together in the same area.
This leads to long periods required on site and a high probability of delays. Other time critical areas are live sites that need additional cabling but where the costs and implications of downtime are unacceptable, such as a trading floor or call centre. Such a facility may need to have all its cabling upgraded or extended in one overnight operation. Busy city centre facilities will also suffer from a lack of parking and loading bays, along with on-site storage restrictions and security worries associated with cable installers needing weeks of access time to the site.
Pre-connectorised cabling should reduce time needed on site by around 75% compared to traditional installation.
Quality of the terminations should also be improved by allowing sophisticated optical fibre terminations to be made in a clean factory environment by skilled people. Each cable assembly can be 100% checked in the factory and whatever is sent to site is known to be of the highest quality.
Optical fibres can be pre-terminated using conventional LC or SC optical connectors. Each fibre has an individual connector on the end. For example, a twelve-fibre cable would have twelve optical connectors on the end. With an MTP array connector one connector terminates the cable. This is simply connected into the back of a standard 1U patch panel which contains the industry standard LC or SC connectors on the front.
