Automatic power reduction is a built-in safety mechanism in modern optical communication systems that detects abnormal conditions, such as a fiber break or accidental disconnection. It instantly reduces or cuts laser output to safe levels. The MR387 Series Emergency Stop Sensor Systems is a new, innovative emergency signaling system that can be deployed in hazardous environments or over long distances – beyond the capabilities of conventional electromechanical solutions. The MR387 E-STOP system employs a photo interrupt scheme. In a fiber-optic communications system, a shut-down apparatus in the event of a fiber-optic cable disruption includes a first optical fiber cable for propagating signals in a first direction and having a plurality of adjacent amplifiers disposed along the first cable. The MR380 fiber optic E-STOP system from Micronor Inc. This white paper will discuss how e-stops work, the standards that govern them and how fiber optic e-stops can provide increased safety in harsh and explosive environments.
