How to handle dust getting into the optical port of a switch
The switches, once filled with dust, can't be cleaned. The finer the dust, the greater the damage it can do to your brand-new devices if you install them too early. Here are a few ways that a little construction dust can have. Dell engineering teams have verified cases in which a fully functional port appears to be a bad port because dirty optical connectors manifest as a port failing loop testing with acceptable power measurement levels. Cable connectors should be cleaned and when stored must be protected from dust. Fiber optic networks are designed to carry light with minimal loss. The truth is simple: dust is the number one enemy of fiber. Ferrule cleaners, when adding liquids to clean the ferrule, but not properly removing the residues. Even when the name gives the idea that they can prevent dust getting in contact with the connector end face, this actually may work in the opposite way depending on the handling and the. Anybody know the best way tooo remove or replace the dust cap/cover of/on a/the optical IN port¿ (so as not tooo bust it¡) thanx dude (s) In the past, I have gently pried the dust cover off. Even tiny contaminants—such as dust, oils, moisture, or other residues—can cause significant signal loss, increased reflectance, and permanent damage when connectors are mated. -

Intelligent Relay Protection Device T and R
The REB670 IED (Intelligent Electronic Device) is designed for the protection and monitoring of busbars, T-connections, and meshed corners from medium to extra high voltage levels in up to six zones. Key highlights Due to its extensive I/O capability, REB670 protects single . To achieve information sharing and interoperability among intelligent electrical equipment in intelligent substations, the author proposes research on relay protection and security technology for the expansion project of intelligent substations. In view of this, this article proposes an enhanced Faster R-CNN algorithm to diagnose the relay protection devices based on image monitoring. The proposed algorithm uses RestNet50 as the main tool o recognize features from input. IRIG-B output is dependent on external clock source, only access to GPS or external IRIG-B source, the Tester's IRIG-B output is effective. -
