Optical passive device product identification apparatus and connectivity determination apparatus

A connectivity determination apparatus comprising:

• an optical input output monitor section monitoring an optical input and an optical output, respectively, of an optical passive device product inside an optical transmission apparatus connected to an optical fiber transmission line;
• a loss calculation section calculating a loss in said optical passive device product based on a monitoring result of said optical input output monitor section;
• and
• a connectivity determination section in which loss characteristic information of said optical passive device product has been stored in advance, and which determines a connectivity of said optical passive device product by comparing said stored loss characteristic information and the loss calculated by said loss calculation section.

An identification apparatus comprising:

• means for monitoring an optical input and an optical output, respectively, of an optical passive device product inside an optical transmission apparatus connected to an optical fiber transmission line, to thereby provide a monitoring result;
• means for calculating a loss in said optical passive device product based on the monitoring result;
• and
• means for identifying said optical passive device product by comparing the calculated loss and stored product information indicating a correspondence between a loss characteristic and a product.
