A field installable connector system for an optical cable includes a clamp, including a plurality of clamp members, cable guiding space in at least one of the clamp members, the cable guiding space configured to guide an optical cable in position in the clamp, connector receiving space in the clamp configured to receive at least part of a connector connected to the optical cable, a stop configured to block withdrawal of the connector from the clamp, and a housing having a clamp receiving space configured to receive at least part of the clamp and to urge clamp parts together to retain in the clamp at least part of the connector. A strain relief also may be provided. A method of assembling a field installable connector system for an optical cable includes placing an optical connector, optical cable and clamp in a hollow housing that holds the clamp relative to the optical connector and optical cable; and applying a strain relief.
