A micro-optical connector holder with an integrated mating system for an optical assembly, typically on a modem PCBA. The integrated mating system is used to hold the micro-optical connectors together during assembly and to apply constant pressure keeping the connectors fully mated. The invention also uses a spring-pin mechanism to keep the holder lid and connectors in place without the use of screws or glue to make assembly easier. The integrated mating system allows the micro-optical connectors to be easily installed and uninstalled for manufacturing and testing purposes. The connector plugs and connector receptacles are aligned and secured by the integrated connector holder.
