摘要： The present paper examines availability and profit analysis of a system comprising four optical lines out of which two are operative (working paths) and the other two are hot-standby (protection paths). Each working line has its own hot standby. On the failure of the working path, signal is received from its own protection path and the failed unit is gone under repair immediately by a repairman. If a working path and its corresponding protection path both get failed then system is said to be failed. The system is analyzed by making use of regenerative point technique. Various measures of system effectiveness as well as expression for finding the profit have been obtained.
