    摘要： An optical device includes a first and second lens group, an operation member, a first and second lens group position detection unit, a storage unit, a control unit. The control unit controls the movement of the second lens group based on positional information of the first lens group detected by the first lens group position detection unit and the positional relationship information stored in the storage unit, and determines whether a control state of the second lens group is abnormal based on control positional information during the control of the movement of the second lens group and the signal corresponding to the position of the second lens group detected by the second lens group position detection unit.

    摘要： In an access network using optical switches, communications between an OLT and ONUs are established without a photoelectric conversion performed at an optical switching unit.The OLT controls the downlink optical switch SW(DOWN) to sequentially select each ONU in slots arranged in a discrete manner, and transmits a Discovery Gate message. Upon receipt of the Discovery Gate message, each ONU consecutively transmits Register Request messages. The uplink optical switch SW(UP) sequentially switch signals from ONU#1 through ONU#128 in the slots arranged in a discrete manner, and outputs the signals to the OLT, Some of the Register Requests transmitted from the respective ONUs pass through the SW(UP), and reach the OLT. Based on the received Register Requests, the OLT determines the timing of transmission for the ONUS, and notifies the ONUS of the timing of transmission through a Gate message.

    摘要： There is provided a system that uses a network matrix to carry out a search for shortest paths from a starting node included in a network having a plurality of nodes to other nodes. The network matrix includes link costs of links and each link has a root end that is a node included in the network and a tail end that is another node connected to the root end. The system includes a processor that includes a circuit for subtracting a lowest value from link costs of the subject links being searched that are included in the network matrix, a circuit for setting tail end node of a link out of the subject links whose link cost has become zero due to the subtracting as a reached node, a circuit for changing link costs of links included in the network matrix whose tail end nodes are the reached node to a value indicating exclusion from further search, and a circuit for setting values after the subtracting of link costs of the subject links whose link costs do not become zero due to the subtracting as link costs of links for a continued search.
