Abstract:
An optical crossconnect apparatus having a first terminal connected to a transmission path from a first optical transmission terminal station and a second terminal connected to a transmission path from a second optical transmission terminal station, and capable of switching said transmission paths when an optical signal is transmitted from said first optical transmission terminal station to said second optical transmission terminal station and from said second optical transmission terminal to said first optical transmission terminal station, comprising:an optical signal switching means having optical signal repeaters; a first optical signal monitoring means, connected between said first terminal and a first port of said optical signal switching means, for monitoring a transmission condition of the optical signal input to said optical switching means; and a second optical signal monitoring means, connected between said second terminal and a second port of said optical signal switching means, for monitoring a transmission condition of the optical signal output from said optical switching means.
