Abstract
Description
- This application is a Continuation of U.S. patent application Ser. No. 15/546,569, filed on Jul. 26, 2017, which is a National Stage Application of PCT/US2016/014955, filed on Jan. 26, 2016, which claims the benefit of U.S. Patent Application Ser. No. 62/107,886, filed on Jan. 26, 2015, the disclosures of which are incorporated herein by reference in their entireties. To the extent appropriate, a claim of priority is made to each of the above disclosed applications.
- The present disclosure relates generally to connection systems for telecommunications networks. Particularly, the present disclosure relates to connection systems capable of accommodating both optical signals and electrical power.
- In today's telecommunications market there is growing demand to support active devices such as fixed location transceivers for generating wireless communication coverage areas (e.g., Wi-Fi access points, macrocells, microcells, picocells, femtocells, other cell sizes, wireless hot spots, nodes, etc.), power-over-Ethernet extenders, and IP devices (e.g., digital cameras such as security cameras, computing devices, etc.). There is also desire to support such devices with faster transmission rates, higher power and longer spans. To achieve faster transmission rates, it is desirable to support such active devices using an optical fiber network. However, traditional fiber optic networks are generally passive (e.g., passive optical local area networks (POLAN), fiber-to-the-home (FTTH), fiber-to-the-desk (FTTD), fiber-to-the-node (FTTN), fiber-to-the-curb (FTTC) and other network architectures) and therefore do not provide ready access to power. Thus, there is a need to support active devices with both electrical power and optical signals in a cost-effective manner. There is also a need to integrate hybrid connectivity (e.g., both power and fiber optics) into existing fiber optic networks.
- One aspect of the present disclosure relates to a hybrid connection system capable of providing connectivity for both fiber optics and electrical power. In certain examples, systems in accordance with the principles of the present disclosure can utilize aspects of existing connector technology to enhance speed-to-market and to facilitate customer acceptance. In certain examples, connection systems in accordance with the principles of the present disclosure can build upon existing connector technology to reduce costs and enhance modularity and compatibility.
- One aspect of the present disclosure relates to a hybrid optical and electrical connection system. The system includes a fiber optic connector including a connector body defining a forward plug end. A ferrule is mounted within the connector body. The ferrule has a ferrule end face accessible at the forward plug end of the connector body. A spring biases the ferrule in a forward direction relative to the connector body and a rear piece is secured to a rear end of the connector body for retaining the spring within the connector body. The system also includes a connector contact holder that attaches to the fiber optic connector. The connector contact holder includes an attachment portion that attaches to the fiber optic connector, a lateral offset portion that extends laterally outwardly from the fiber optic connector and a forward extension structure that projects forwardly from the lateral offset portion toward the forward end of the connector body. The forward extension structure includes connector contact mounts. The system further includes connector electrical contacts held by the connector contact mounts. In certain examples, the connector electrical contacts can be held within the connector contact mounts by a snap-fit connection. In certain examples, the connector electrical contacts can include contact pins or contact sockets. In certain examples, the fiber optic connector is an SC-type connector.
