Abstract

The present disclosure relates generally to a fiber optic jumper including a fiber optic cable that extends between first and second cable ends. The fiber optic cable includes a cable jacket containing at least first and second optical fibers. The fiber optic jumper also includes an optical transceiver module directly terminated at the first end of the fiber optic cable, and at least one fiber optic connector directly terminated at the second end of the fiber optic cable. The fiber optic jumper is outdoor rated for temperatures ranging from minus 40 to 75 degrees Celsius.

First claim

What is claimed is:

1. A fiber optic jumper comprising:
a fiber optic cable that extends between first and second cable ends, the fiber optic cable including a cable jacket containing at least first and second optical fibers;
an optical transceiver module directly terminated at the first end of the fiber optic cable, the optical transceiver module comprising a printed circuit board including an edge defining a card edge connector electrical interface configured to receive a first electrical signal through a first electrical contact, and to transmit a second electrical signal through a second electrical contact, the printed circuit board further including an optical transmitter for converting the first electrical signal into a first optical signal, and an optical receiver for converting a second optical signal into the second electrical signal; and
at least one fiber optic connector directly terminated at the second end of the fiber optic cable, the at least one fiber optic connector being a hardened fiber optic connector;
wherein the fiber optic jumper is constructed of materials configured to enable operation of the fiber optic jumper at temperatures ranging from −40 to 70 degrees Celsius.

2. The fiber optic jumper of claim 1 , wherein the optical transceiver module includes a connector body having a SFP form factor.

3. The fiber optic jumper of claim 2 , further comprising an outer housing that at least partially surrounds the connector body.

4. The fiber optic jumper of claim 3 , wherein the outer housing is adapted to fasten with respect to a connector receiver including a port for receiving the connector body to provide an electrical connection with the optical transceiver module.

5. The fiber optic jumper of claim 4 , wherein an environmental seal is formed between the outer housing and the connector receiver.

6. The fiber optic jumper of claim 4 , wherein the outer housing fastens to the connector receiver by a threaded connection, a bayonet-style connection, or a push-pull connection.

7. The fiber optic jumper of claim 1 , wherein the fiber optic cable is environmentally sealed with respect to a rear end of the optical transceiver module.

8. The fiber optic jumper of claim 7 , further comprising a shape-memory sleeve for providing sealing between the fiber optic cable and the rear end of the optical transceiver module.

9. The fiber optic jumper of claim 1 , wherein the optical transceiver module is adapted to environmentally seal with respect to a connector receiver including a port for receiving a plug end of the optical transceiver module to provide an electrical connection with the optical transceiver module.

10. The fiber optic jumper of claim 1 , wherein the optical transceiver module is configured to support 10 gigabit per second data rates.

11. The fiber optic jumper of claim 1 , wherein the optical transceiver module is configured to support 25 gigabit per second data rates.

12. The fiber optic jumper of claim 1 , wherein a tensile strength element of the fiber optic cable is anchored to a rear end of the optical transceiver module.

13. The fiber optic jumper of claim 1 , wherein both the first and second optic fibers are supported at a single fiber optic connector having at least one ferrule.

14. The fiber optic jumper of claim 13 , wherein the single fiber optic connector has a first ferrule for supporting the first optical fiber and a second ferrule for supporting the second optical fiber.

15. The fiber optic jumper of claim 1 , wherein the fiber optic cable is sealed relative to the hardened fiber optic connector and a tensile strength element of the fiber optic cable is anchored to a rear end of the hardened fiber optic connector.

16. The fiber optic jumper of claim 15 , wherein the hardened fiber optic connector includes a twist-to-secure fastener for securing the hardened fiber optic connector to a fiber optic adapter or another fiber optic connector.

17. The fiber optic jumper of claim 1 , wherein a rear end of the hardened fiber optic connector is sealed relative to the fiber optic cable by a gasket.

18. The fiber optic jumper of claim 1 , wherein a rear end of the hardened fiber optic connector is sealed relative to the fiber optic cable by a shape memory sleeve.

19. A fiber optic jumper comprising:
a fiber optic cable that extends between first and second cable ends, the fiber optic cable including a cable jacket containing at least first and second optical fibers;
an optical transceiver module directly terminated at the first end of the fiber optic cable, the optical transceiver module including a connector body having a SFP form factor;
at least one hardened fiber optic connector directly terminated at the second end of the fiber optic cable; and
an outer housing that at least partially surrounds the connector body, the outer housing being adapted to fasten with respect to a connector receiver including a port for receiving the connector body to provide an electrical connection with the optical transceiver module, wherein an environmental seal is formed between the outer housing and the connector receiver;
wherein the fiber optic cable is sealed relative to the hardened fiber optic connector and a tensile strength element of the fiber optic cable is anchored to a rear end of the hardened fiber optic connector, and wherein the hardened fiber optic connector includes a twist-to-secure fastener for securing the hardened fiber optic connector to a fiber optic adapter or another fiber optic connector.

20. The fiber optic jumper of claim 19 , wherein the tensile strength element of the fiber optic cable is anchored to the rear end of the hardened fiber optic connector by a crimp sleeve.

21. A fiber optic jumper comprising:
a fiber optic cable that extends between first and second cable ends, the fiber optic cable including a cable jacket containing at least first and second optical fibers;
an optical transceiver module directly terminated at the first end of the fiber optic cable, wherein the fiber optic cable is environmentally sealed with respect to a rear end of the optical transceiver module, further comprising a shape-memory sleeve for providing sealing between the fiber optic cable and the rear end of the optical transceiver module, and wherein the optical transceiver module is adapted to environmentally seal with respect to a connector receiver including a port for receiving a plug end of the optical transceiver module to provide an electrical connection with the optical transceiver module; and
at least one fiber optic connector directly terminated at the second end of the fiber optic cable, the at least one fiber optic connector being hardened.
