The first connection an optic makes is with the fiber end face. All too often we find that customers are cleaning their optics, reconnecting them, and still experiencing network downtime. Most of the time, it is because an optic was cleaned, but the fiber end face was never inspected.
If a fiber end face is dirty, the link will either not perform to the level it should, or it will read errors and the signal will not travel its full distance. Alternatively, if you have a dirty fiber end face, you will continue dirtying optics until the end face is 100 percent clean. In an industry all about uptime, dirty end faces are simply not an option. To ensure your network is running the way it is supposed to, it is important to inspect a fiber end face after you have successfully cleaned an optic. Let me tell you how to do that.
