Abstract

A single line converter module comprises a housing; an environmentally hardened fiber optic connector located in the housing and configured to be optically coupled to a service terminal for receiving downstream optical frames; a single electrical connector located in the housing and coupled over a metallic medium to a network terminal providing a service to respective customer premise equipment (CPE); and an optical-to-electrical (O/E) converter located in the housing and configured to convert the downstream optical frames to an electrical signal for transmission over the metallic medium to the network terminal.

First claim

What is claimed is:

1. A single line converter module comprising:
a housing;
a fiber optic connector integrated with the housing, wherein the fiber optic connector is configured to mount directly to a fiber optic connector in a service terminal;
a single electrical connector located in the housing and coupled over a metallic medium to a single network terminal; and
an optical-to-electrical (O/E) converter located in the housing and coupled to the fiber optic connector and the single electrical connector, the O/E converter configured to convert between optical frames communicated via the fiber optic connector and electrical signals communicated via the metallic medium, for just the single network terminal.

2. The single line converter module of claim 1 , wherein one or both of the single electrical connector and the fiber optic connector is an environmentally hardened connector manufactured for use in outdoor conditions.

3. The single line converter module of claim 1 , wherein the housing is an environmentally hardened housing configured for use in an outdoor environment.

4. The single line converter module of claim 1 , wherein the housing includes one or more heat transfer features comprising at least heat dissipation fins configured to dissipate heat generated during the O/E conversion.

5. The single line converter module of claim 1 , wherein the single line converter module receives power over the metallic medium from the single network terminal.

6. The single line converter module of claim 1 , wherein the fiber optic connector comprises a hybrid fiber/electrical connector configured to provide power to the single line converter module.

7. The single line converter module of claim 1 , wherein the single line converter module is coupled to a passive fiber optic network via the fiber optic connector of the service terminal.

8. The single line converter module of claim 7 , wherein the passive fiber optic network is coupled to a core network by an optical line terminal.

9. The single line converter module of claim 7 , wherein the passive fiber optic network comprises at least one of a Gigabit-capable Passive Optical Network (GPON), a Ten-Gigabit-capable Passive Optical Network (XGPON), or an ETHERNET Passive Optical Network (EPON).

10. The single line converter module of claim 1 , wherein the single line converter module is configured to transmit electrical signals according to either Very-high-bit-rate digital subscriber line 2 (VDSL2) technology, or G.Fast technology.

11. A method for a single line converter module, the method comprising:
communicating optical frames between a single line converter module and a service terminal having a plurality of fiber optic drop cable ports, wherein the single line converter comprises an integrated optical connector mounted directly to a respective one of the plurality of fiber optic drop cable ports;
communicating via electrical signals between the single line converter module and one network terminal over a metallic medium, wherein the single line converter module coverts communications between the optical frames and the electrical signals for just the one network terminal.

12. The method of claim 11 , further comprising:
communicating optical frames between an optical line terminal in a passive fiber optic network and the service terminal.

13. The method of claim 12 , wherein the passive fiber optic network is coupled to a core network by the optical line terminal.

14. The method of claim 11 , wherein the passive fiber optic network comprises at least one of a Gigabit-capable Passive Optical Network (GPON), a Ten-Gigabit-capable Passive Optical Network (XGPON), or an ETHERNET Passive Optical Network (EPON).

15. The method of claim 11 , further comprising:
providing power to the single line converter module over the metallic medium.

16. The method of claim 11 , wherein each of the plurality of fiber optic drop cable ports is a hybrid fiber/electrical connector, the method further comprising:
providing power to the single line converter module over a metallic medium coupling the hybrid fiber/electrical connector to the single line converter module.

17. The method of claim 11 , wherein communicating via electrical signals comprises one of:
transmitting the electrical signals according to Very-high-bit-rate digital subscriber line 2 (VDSL2) technology; or
transmitting the electrical signals according to G.Fast technology.

18. The method of claim 11 , where the single line converter module comprises an environmentally hardened housing configured for use in an outdoor environment.

19. The method of claim 11 , wherein the integrated optical connector of the single line converter module outputs upstream optical signals to the service terminal and inputs downstream optical signals from the service terminal.
