an electrical interface for receiving or transmitting power on an electrical wire in the fiber and power cable, said electrical interface comprising an electrical contact for engagement with a contact plate on the connector coupled to the electrical wire; and
a power component for transferring the power to or from a network communications device with the optical module installed in the network communications device;
wherein the connector comprises a slide cover for covering the contact plate when the connector is removed from the optical module.
7. The optical module of claim 1 further comprising an element for engagement with a protective slide cover of the connector.
8. The optical module of claim 1 further comprising an electrical signal interface for transmittal of the electrical signal.
9. The optical module of claim 1 wherein the optical module comprises the receptacle for receiving the power post of the optical module cage.
10. The optical module of claim 1 wherein the electrical wire is configured for transmitting pulse power.
11. The optical module of claim 1 wherein the connector comprises a latch for engagement and disengagement of the connector with the connection port.
12. The optical module of claim 1 wherein the connection port is configured for receiving two connectors.
13. The optical module of claim 1 wherein the connector comprises a crimp mechanism for attachment of the electrical wire.
14. The optical module of claim 1 wherein said optical interface is located at a first wall of said connection port for receiving a ferrule coupled to the optical fiber, and said electrical contact is located on a second wall of said connection port.
15. The optical module of claim 1 wherein a rear of the optical module located at an opposite end from said connection port comprises the power post and an electrical signal interface for transmitting or receiving data.
