TEST & MEASUREMENT


2. Less than one, but still delivers performance in terms of insertion and return loss


3. Less than two, but still delivers performance


4. Adequate, but poses a risk to other interfaces


Results 2-4 are considered


unacceptable and fall under the coin- toss category. Luckily, the uncomfortable coin-toss situation can be mitigated thanks to pass/fail software, available for advanced test equipment platforms and PCs. This software has the advantages of providing the technician with clear pass/fail criteria, which eliminate guesswork, as well as a diagnosis of why the connector has failed.


Conclusion Contamination can only be identified through video inspection. A skilled technician may be able to interpret an OTDR reading from a light source and power meter, but that kind of experience is not gained overnight. The need to deploy far-reaching


networks and high bandwidths is diluting the pool of skilled technical workers. The time required to train every technician on how to use new tools and proper inspection techniques is not always available. This lack of training leads to misconceptions about the best cleaning methods to use when opening or installing a new connection. The best way for a technician to handle connector contamination is


to implement a strict cleaning and inspection technique as well as learn to recognize the effects of cleaning on test results. In short, always inspect and clean prior to connecting; failing to inspect will only lead to repeat jobs. The last major issue operators


and carriers must contend with is cost control. The best way to reduce unnecessary truck rolls and delays is to employ the best practices at every step of the connector-handling process. In short, all connectors must be


inspected and cleaned through proper inspection. This is the best way to prevent network performance and quality issues.
