Abstract
The present invention discloses a low-cost high power optical adapter employed to reduce the effects of the contaminants in the high power fiber optical transmission systems. The high power optical adapter uses the exactly same housing of the standard plug style single mode optical attenuators. The attenuating fiber is replaced by a TEC fiber. The TEC fiber has an MFD of more than 25 um at one end and an MFD of about 10 um at the other end that is the same as a standard single mode fiber. In the high power optical adapter, the large MFD end of the TEC fiber is fixed at the male side of the ferrule and the small MFD end of the TEC fiber is fixed at the female side of the ferrule. When the high power optical adapter is employed, the original pair of the standard optical connectors are first disconnected from the standard mating sleeve. Then each of these connectors is mounted into the female sides of a pair of the high power optical adapters. Then the male sides of the pair of the high power optical adapters are connected together through the standard mating sleeve. During the system test, if the high power optical adapters are not needed, then the standard optical connectors can be …
