The Emcore Medallion 2100 Optical A/B Switch is a high-performance solution for network protection and optical redundancy. Packaged in convenient 1 RU housing, this line of optical switches provides an automatic or manual fiber switching function to protect the network from inadvertent service outages due to up-stream optical signal degradation. Each fiber’s optical signal power level is continuously monitored, as is an adjustable optical trip threshold for each channel. If the primary fiber’s optical signal power level falls below the desired optical trip threshold, the unit automatically switches to the secondary fiber, thus eliminating the need for intervention of a system operator. The Medallion 2100 is capable of manual switching or can be switched remotely via SNMP or via a WEB browser adding optical protection to many system applications.
