The recent development of 4G mobile communication system has led to the rapid technology shift from conventional repeater systems using coaxial cable links towards new fiber optic repeater systems using fiber-optic links between the base station and the outdoor fiber optic repeater. The technical changes have brought up the increasing needs of robust optic links that can be used in harsh environments. Based on the most demanding requirements, a new outdoor optical connector employing 2-channel fiber optics, uplink and downlink, has been developed for the applications where the rugged environmental protection is essential. This paper describes the development of the new connector along with the design criteria and performance results. In summarizing, the prototype optical connectors have undergone extensive laboratory and field test, and they have shown exceptional optical and mechanical characteristics under extreme environmental conditions. The connectors have also exhibited capabilities of providing fast and easy installation while maintaining high performance fiber optic connections.
