FDK Corporation, represented by Tokyo Components , has developed the YS-1210 2x2 optical switch, considered to be the smallest magneto-optical switch in the world.
Along with a compact footprint, the new switch is also lower in price.
The optical switch is used to route the direction of transmission towards a back-up link when failures occur in an optical-communications network.
Recently, the optical switch has been used in all areas of the access and metropolitan networks and has seen the expansion of its application into OADM (Optical Add Drop Multiplexer) equipment and OXC (Optical Cross-connect) equipment.
In order to meet new demands, FDK utilised the magneto-optical technology that has been a core-competency for them for years, to develop a much smaller but highly efficient product.
Since the YS-1210 has no movable parts, it has higher reliability and faster response time compared with mechanical types. Moreover, a serious cost reduction is achieved by using a miller to miniaturise optical parts up to 60% compared to conventional products.
Required mounting space has been reduced by arranging the input and output ports on the same side. The switch latches into position, even when there is no current applied.
Overall, the YS-1210 is a highly efficient optical switch with outstanding performance.
