摘要： In order that the various ring-switching modes of 2-Fiber BLSR, 4-Fiber BLSR and UPSR may be switched merely by changing a software, space division switches are disposed across an add drop switch, and one output drop switch and one output of the second space division switch are connected with the input stage of a selector which can be selected at the unit of a time slot. As a result, the various ring-switching modes can be switched merely by changing the software while suppressing the scale of the switch. Moreover, the change from the ring switch to the linear switch and vice versa can be effected.

摘要： First stage and third stage four-input four-output space division switches are arranged before and after a second stage time division switch, and two outputs of the first stage space division switch and two inputs of the third stage space division switch are connected by bypassing the time division switch. The time division switch has n control memories. A first control memory stores connection information in a normal state of each path set in the transmission line, a second control memory stores connection information of a first alternative path when failures occur in a path, and an n-th control memory (n is any integer equal or greater than 3) stores connection information of an (n-1)th alternative path, and a control memory corresponding the a failure pattern is selected from the n control memories for each path.

摘要： A self-healing ring switch transmission system uses space division switches disposed upstream and downstream of an add drop switch in order to determine a correspondence with a plurality of ring-switch modes by merely changing the software. This is accomplished by having one output highway of the add drop switch and one output highway of a space division switch connected with an input stage of a selector for selecting one time slot of the two output highways.

The system also accomplishes the optical transmission to a short distance by directly connecting the linear terminals therebetween, with an electric-to-optic converter replaced by an electric-to-optic converter having a semiconductor amplifier, with an optic-to-electric converter by an optic-to-electric converter having an avalanche photodiode as light receiver, an with no use of any optical booster amplifier and optical preamplifier in the multiplexing line terminal. With these, the optical transmission system can be easily constructed depending on the transmission distance required.
