Method of controlling transmission apparatus, transmission apparatus, and recording medium

A transmission apparatus including a plurality of ports capable of connection to an optical module, the transmission apparatus comprising:

• a memory;
• and
• a processor coupled to the memory and configured to:
• receive operating time information indicating information of operating time of the optical module, and monitor information including at least one of information on temperature of the optical module, optical output power of the optical module, and a bias current value of a semiconductor laser disposed in the optical module at predetermined time intervals, when the optical module is connected to any first port of the plurality of ports,
• calculate a deterioration point indicating a deterioration degree of the optical module based on the operating time information and the monitor information at the predetermined time intervals,
• calculate an accumulated deterioration point by adding the deterioration point calculated at the predetermined time intervals, and
• determine a deterioration degree of the optical module based on the accumulated deterioration point, when the optical module is recoupled to the first port, or when the optical module is coupled to a second port different from the first port among the plurality of ports.

A computer-readable recording medium storing a program causing a computer to execute a process, the process comprising:

• receiving operating time indicating information of operating time of the optical module, and monitor information including at least one of information on temperature of the optical module, optical output power of the optical module, and a bias current value of a semiconductor laser disposed in the optical module at the predetermined time intervals, when a module is coupled to any first port of a plurality of ports disposed on a transmission apparatus;
• calculating a deterioration point indicating a deterioration degree of the optical module based on the operating time information and the monitor information at the predetermined time intervals;
• calculating an accumulated deterioration point by adding the deterioration point calculated at the predetermined time intervals;
• and
• determining a deterioration degree of the optical module based on the accumulated deterioration point, when the optical module is reconnected to the first port, or when the optical module is connected to a second port different from the first port among the plurality of ports.
