Hybrid optical connector
Connector systems that carry electrical signals and optical signals in a single connector are provided. A male electro-optical connector can have an electrical insert portion that fits into a receptacle of a female electro-optical connector to provide a structural connection. The optical interface can be advantageously near a front of the connectors for easy maintenance. Optical connectors with a relatively large diameter for the optical interface are also provided. Optical connectors can include a collector for receiving optical signals at a large opening and providing signals to a photodiode at a small opening of the collector. Such optical connectors with a large diameter for an optical interface can advantageously provide reduced alignment tolerances. Adapters, cable adapters, docking stations, and other apparatus can also be provided.
