Connectors for composite fiber optic/coaxial cables and related connectorized cables and methods
A connector for a composite communications cable includes a connector body, a contact post mounted within the connector body, a compression sleeve that is received within a rear end of the connector body and an optical fiber passage at a front end of the connector.
1. A method of upgrading a coaxial cable cabling connection to a fiber optic cabling connection, the method comprising:
removing a coaxial connector from a first end of a composite communications cable, the composite communications cable including:
a cylindrical spacer;
a center conductor coaxially centered within the cylindrical spacer;
an outer conductor surrounding the cylindrical spacer;
an outer jacket surrounding the outer conductor; and
an unused optical fiber positioned within the outer jacket of the composite communications cable;
exposing a first end portion of the optical fiber of the composite communications cable at the first end of the composite communications cable;
inserting the first end of the composite communications cable into a compression connector so that the first end portion of the optical fiber extends through an optical fiber passage of the compression connector; and
compressing a compression sleeve of the compression connector to lock the composite communications cable in place inside the compression connector;
wherein the compression connector is optically connected to the first end portion of the optical fiber to convert a termination of the composite communications cable from a coaxial cable connection to a fiber optic connection without an electrical connection.
2. The method of claim 1 , wherein the compression connector includes:
a connector body; and
a contact post mounted within the connector body that is configured to receive both a first end portion of the center conductor of the composite communications cable and the first end portion of the optical fiber,
wherein the optical fiber passage extends from a front end of the connector body and the compression sleeve is received within a rear end of the connector body.
3. The method of claim 2 , wherein the front end of the connector body includes external threads, the method further comprising threading a jam nut onto the external threads to mount the compression connector on a mounting structure.
4. The method of claim 3 , wherein the optical fiber passage includes at least one external protrusion, the method further comprising mounting a furcation tube onto a front end of the optical fiber passage.
5. The method of claim 4 , the method further comprising installing a heat shrinkable material over the external protrusion of the optical fiber passage and over at least a portion of the furcation tube.
6. The method of claim 1 , wherein the outer conductor of the composite communications cable provides strain relief once the composite communications cable is locked in place inside the compression connector.
7. The method of claim 1 , wherein the optical fiber passage includes first and second channels, the method further comprising passing the first end portion of the optical fiber through the first channel and passing the center conductor of the composite communications cable through the second channel.
8. The method of claim 2 , wherein a furcation tube extends from a front end of the optical fiber passage, and wherein the center conductor of the composite communications cable extends through both the optical fiber passage and the furcation tube.
9. The method of claim 1 , wherein the first end portion of the optical fiber exposed is from about 18 to about 24 inches.
10. A method of upgrading a coaxial cable cabling connection to a fiber optic cabling connection, the method comprising:
removing a coaxial connector from a first end of a composite communications cable, the composite communications cable including:
a cylindrical spacer;
a center conductor coaxially centered within the cylindrical spacer;
an outer conductor surrounding the cylindrical spacer;
an outer jacket surrounding the outer conductor; and
an unused optical fiber positioned within the outer jacket of the composite communications cable;
exposing a first end portion of the optical fiber of the composite communications cable at the first end of the composite communications cable; and
installing a fiber optic connector to the composite communications cable, wherein the fiber optic connector is optically connected to the first end portion of the optical fiber to convert a termination of the composite communications cable from a coaxial cable connection to a fiber optic connection without an electrical connection.
