Fujikura has released an optical siwtch for switching an optical fiber path between different sets of transmission equipment. A redundant network is configured by monitoring an optical power level down and automatically switching the main path to a standby path if an alarm generates in the main path. The redundant network configuration between different manufacture’s transmission equipment is also formed easily by using a coupler unit. Table 1, Fig.1 and Fig.2 show product specification, appearance and system configuration, respectively. New Products Redundant Optical Fiber Features 1. Compact size and scalability ·Up to 8 channels per (19 inch rack 1U size) ·Hot plug-in switch unit design and unit expansion per 2 channels 2. Safety design ·Connection keeps when power supply is failed. 3. Fast switching ·Switching speed : Less than 10ms 4. Easy operation ·Simple Network Management Protocol (SNMP) notification ·Centalized management by OPeration System (OPS) for all redundant optical switches Switch Fiber Optics Components Division Fiber Optics Network Product R&D Department Takamizawa Table 1.
