PURPOSE:To reduce the loss of an optical connector and to make the size of an optical wire box small by providing n-set of optical input ports and optical output ports and adopting the structure such that a signal made incident in the 1st optical input port is radiated from optical output ports of the (i+1)-th order or over. CONSTITUTION:A function is provided, in which the n-set of optical output ports O2-O5 and n-set of optical input ports I1-I4 are provided a signal made incident from the i-th order of optical input port is radiated from the optical output ports of the (i+1)-th or over. Since plural nodes are connected by using (3m+1) sets of optical accessors, the cost per one node is decreased, the optical loss between nodes is reduced and the size of the optical wire box accommodating the optical accessors is decreased. Then the multi-port optical accessors 3m with excellent reliability, extension of nodes, correspondence to transfer, economy and external appearance are obtained. |
