Media converter to enable ethernet in thin-profile mobile devices
A media converter to enable Ethernet in thin-profile mobile devices. The media converter can be designed to interface with a thin-profile mobile device via a short-reach Ethernet link and to interface with a network device via a conventional Ethernet link. Protocol conversion is therefore obviated, while accommodating a low-profile Ethernet port in the mobile device.
1. A media converter device, comprising:
a first Ethernet physical layer device comprising a low profile Ethernet port, the first Ethernet physical layer device designed to communicate with a first device over a first Ethernet link that terminates on a corresponding low profile Ethernet port on the first device, the first Ethernet link having a first link rate and being limited to a short reach link distance;
a second Ethernet physical layer device comprising an RJ-45 Ethernet port, the second Ethernet physical layer device designed to communicate with a second device over a second Ethernet link that terminates on a corresponding RJ-45 Ethernet port of the second device, the second Ethernet link having a second link rate, wherein the low profile Ethernet port is smaller in height as compared to the RJ-45 Ethernet port; and
a bridge device that transfers traffic between the first Ethernet physical layer device and the second Ethernet physical layer device.
2. The media converter device of claim 1 , wherein the short reach link distance is less than 0.5 meters.
3. The media converter device of claim 1 , wherein the first Ethernet physical layer device supports Ethernet communication over less than four wire pairs.
4. The media converter device of claim 3 , wherein the first Ethernet physical layer device supports Ethernet communication over a single wire pair.
5. The media converter device of claim 4 , wherein the second Ethernet physical layer device supports Ethernet communication over four wire pairs.
6. The media converter device of claim 1 , wherein the media converter device is a dongle having an end that contains the first Ethernet physical layer device, the first end of the device being configured for insertion into the low profile Ethernet port of the first device.
7. The media converter device of claim 1 , wherein the second Ethernet link supports link distances up to 100 meters.
8. The media converter device of claim 1 , wherein the first link rate is the same as the second link rate.
9. The media converter device of claim 1 , wherein the first link rate is lower than the second link rate, and the bridge device is configured to perform a rate adaptation between the first Ethernet physical layer device and the second Ethernet physical layer device.
10. The media converter device of claim 1 , further comprising an internal port that is coupled to the bridge device, the internal port being configured to pass Ethernet traffic received from one of the first device and the second device to the media converter device for management of the media converter device.
11. The media converter device of claim 1 , wherein the media converter device is part of a wall connector device.
12. The media converter device of claim 1 , wherein the media converter device is part of a docking station.
13. The media converter device of claim 1 , wherein the media converter device is part of a case for a mobile computing device.
14. A media converter device, comprising:
a first Ethernet physical layer device comprising a low profile Ethernet port designed to communicate with a mobile computing device over a first link that terminates on a corresponding low profile Ethernet port of the mobile computing device;
a second Ethernet physical layer device comprising an RJ-45 Ethernet port designed to communicate with a network device over a second link that terminates on a corresponding RJ-45 Ethernet port of the network device, wherein the low profile Ethernet port is smaller in height as compared to the RJ-45 Ethernet port; and
a buffer device that couples the first and second Ethernet physical layer devices.
15. The media converter device of claim 14 , wherein the mobile computing device is a laptop device.
16. The media converter device of claim 14 , wherein the mobile computing device is a mobile phone device.
17. The media converter device of claim 14 , wherein the mobile computing device is a tablet device.
18. The media converter device of claim 14 , wherein the media converter device is a dongle device.
19. The media converter device of claim 14 , wherein the media converter device is part of a docking station.
20. A media converter device, comprising:
an RJ-45 Ethernet interface configured to operate over a first distance;
a NU-45 Ethernet interface configured to operate over a second distance less than the first distance, the NU-45 Ethernet interface smaller in height than the RJ-45 Ethernet interface; and
a bridge device configured to transfer traffic between the RJ-45 Ethernet interface and the NU-45 Ethernet interface.
