Single reel inspection work includes: checking, counting, appearance inspection and measurement of the specifications and quantity of optical cables and connecting equipment transported to the site, and measuring the main optoelectronic characteristics. Through inspection, it is confirmed whether. The process of testing any fiber optic cable plant during and after installation includes all the procedures covered so far. Finding the run faulty, you determine the problem is not with the terminations but with the cable, itself. Was the cable faulty to begin with--in which case you can invoke the cable manufacturer's guarantee--or was it. There are two reasons we may want to test bare fiber, by that we mean fiber that has not been terminated in connectors but is simply plain optical fiber, The first one is to ensure the fiber or cable being manufactured meets its specifications, as is done by every manufacturer.
