ANSWERS) |ALREADY GRADED A+
When would a mid-entry splice in a fiber-optic network be used? - ANSWER- In a self-healing ring network that requires only two fibers to feed an optical fiber drop.
What is required of mechanical splices used for acceptance testing? - ANSWER- A mechanical splice used for acceptance testing should be simple to use and reusable.
What are some prerequisites before performing a fusion splice of optical fibers? - ANSWER- A controlled environment such as a splicing van, trailer or tent and a stable work surface that is large enough to accommodate the fusion splicer, tools, and the splice closure.

Why are Velcro straps preferred over standard plastic tie wraps when bundling pigtails for storage in a splice panel? - ANSWER- Because Velcro straps are removable and can hold the pigtails together without placing undue strain on the optical fibers
When preparing fiber-optic cable for connection to a patch panel, how much buffer tube and fiber slack should be provided? - ANSWER- Leave enough slack in the buffer tubes to allow the splice trays to reach the splicing equipment and enough fiber slack to store on individual trays for later additions, moves and changes
If tight-buffered distribution fiber optic cable is installed between the master splice panel in an optical entrance enclosure (0EE) and a rack-mounted fiber-optic distribution panel, where in the facility must the distribution panel be located? - ANSWER- The distribution panel can be located anywhere in the facility since the distribution cable complies with indoor code requirements for riser or plenum installations.
The quality and attenuation value of a mechanical splice of optical fibers is dependent on which tool during the preparation process? - ANSWER- The quality and attenuation value of the mechanical splice of optical fibers is dependent on the quality of the cleaving tool. 2 / 3

What step should be performed at the beginning of every fusion splicing operation? - ANSWER- Make a number of test splices to set up the fusion splicer and to verify the instrument's settings and calibration for both the environment and the type of fiber to be spliced.
Which fusion splicer alignment method uses a camera to align the optical fibers before splicing? - ANSWER- The profile alignment system (PAS) method.
The National Electrical Safety Code (NESC) provides guidelines concerning which portion of the fiber-optic cable network? - ANSWER- Minimum safety clearances between different conductors of overhead and underground electric supply and communications lines.
What is a safety concern when aerial fiber-optic cable is installed between poles, even though there are no high-voltage power lines? - ANSWER- The buildup of lethal amounts of static electricity on the fiber-optic cable that can discharge through a person on a ladder or some other conductor connected to ground.
