Abstract

Communication devices are disclosed. In an example embodiment, a communication device may include a communication module including an illumination source and a body element. The body element may be configured to allow illumination generated by the illumination source to propagate within and illuminate at least a portion of an outer surface of the body element.

First claim

What is claimed is:

1. A communication device comprising:
a first communication module including:
a first illumination source,
a first body element configured to allow illumination generated by the first illumination source to propagate within and illuminate at least a portion of an outer surface of the first body element, and
a sensor configured to detect a physical input applied at the first communication module;

a cable configured to transmit signals to and from the first communication module; and
a second communication module including:
a second illumination source, and
a second body element configured to allow illumination generated by the second illumination source to propagate within and illuminate at least a portion of an outer surface of the second body element,

wherein the first communication module is configured to transmit a command to the second communication module via the cable based at least in part on the sensor detecting the physical input at the first communication module, and
wherein the second communication module is configured to turn on the second illumination source based at least in part on the command.

2. The communication device of claim 1 , wherein the command is transmitted via an out-of-band signal.

3. The communication device of claim 2 , wherein the out-of-band signal includes varying an intensity of an optical signal.

4. The communication device of claim 3 , wherein the out-of-band signal includes direct-current light pulses of an optical signal.

5. The communication device of claim 1 , wherein the sensor is configured to detect the physical input including a force applied to the first communication module toward a host device connected to the first communication module.

6. The communication device of claim 5 , wherein the sensor includes a redundant ground contact positioned to form:
an open electrical configuration with a connector of the host device when the first communication module is nominally positioned relative to the host device, and
a closed electrical configuration with the connector of the host device when the force is applied to the first communication module toward the host device.

7. The communication device of claim 1 , wherein the sensor is configured to detect the physical input including a force applied to the first communication module away from a host device connected to the first communication module.

8. The communication device of claim 1 , wherein the sensor is configured to detect the physical input including a force applied to the first communication module substantially parallel to a host device connected to the first communication module.

9. The communication device of claim 8 , wherein the sensor is configured to detect temporary physical input against a baseline state determined from a long average of the physical input sensed by the sensor.

10. The communication device of claim 1 , wherein the sensor is configured to detect the physical input including a body proximate to or in contact with the sensor.

11. The communication device of claim 1 , wherein the first body element comprises a protrusion configured to enable a person to grip and remove the first communication module from a retaining connection.

12. The communication device of claim 1 , wherein the first communication module is configured to turn on the first illumination source based at least in part on a diagnostic state of the first communication module.

13. The communication device of claim 12 , wherein the diagnostic state of the first communication module includes an alarm or warning set point triggered by at least one of: a transmission power of the first communication module, a receiver input power of the first communication module, a temperature of the first communication module, or a bias current of the first communication module.

14. The communication device of claim 12 , wherein the diagnostic state of the first communication module includes at least one of: a jitter of a signal at the first communication module, input amplitudes of the signal at the first communication module, output amplitudes of the signal at the first communication module, loss of signal (LOS), and other fault conditions.

15. The communication device of claim 1 , wherein the first communication module is configured to turn on the first illumination source based at least in part on a signal from a host device.

16. A communication module comprising a sensor configured to detect a temporary physical input applied at the communication module against a baseline state determined from a long average of the temporary physical input sensed by the sensor, the temporary physical input including a force applied to the communication module substantially parallel to a host device connected to the communication module, the sensor being in communication with the communication module such that the communication module performs an act in response to the temporary physical input applied at the communication module.

17. The communication device of claim 1 , wherein the first illumination source is capable of producing a plurality of colors.

18. The communication device of claim 17 , wherein at least one of the plurality of colors indicates a diagnostic state of the first communication module.

19. The communication device of claim 17 , wherein at least one of the plurality of colors indicates a physical address label of the second communication module.

20. The communication device of claim 1 , wherein the first illumination source is capable of flashing on and off at a plurality of rates.

21. The communication device of claim 20 , wherein at least one of the plurality of rates indicates a diagnostic state of the first communication module.

22. The communication device of claim 20 , wherein at least one of the plurality of rates indicates a physical address label of the second communication module.

23. The communication module of claim 16 , wherein:
the act performed in response to the temporary physical input applied at the communication module includes illumination of an illumination source of the communication module.

24. The communication module of claim 23 , wherein the illumination of the illumination source indicates a diagnostic state of the communication module.

25. The communication module of claim 23 , wherein the illumination of the illumination source indicates a physical address label of a second communication module communicatively coupled to the communication module.

26. The communication module of claim 23 , wherein the illumination source is capable of flashing on and off at a plurality of rates.

27. The communication module of claim 23 , wherein the illumination source is capable of producing a plurality of colors.
