SYSTEM AND METHOD FOR COMMUNICATING OPTICAL SIGNALS VIA COMMUNICATION CABLE MEDIUM

Abstract

A data communication system is disclosed including a cable medium and modulator adapted to carry data and power between a high speed data source and a high speed data sink. Relatively high speed data (e.g. the TMDS data of an HDMI interface) may be carried on optical waveguides in the cable medium. Relatively low-speed data (e.g., DDC data and clock, and CEC of an HDMI interface) may be carried on a separate set of optical waveguides or wire mediums. The optical waveguides allow for substantially less signal distortion of the high-speed data, thereby allowing the cable medium to achieve much higher lengths without significantly affecting the high-speed signaling.

Description

FIELD

This disclosure relates generally to data communication mediums, and in particular, to a system and method for communicating data and power using optical and electrical integrated medium.

BACKGROUND

Consumer multimedia systems of today typically consists of one or more video and audio (V/A) sources communicatively coupled to one or more V/A sinks. Examples of V/A sources include DVD players, Blu-ray players, set-top boxes, camcorders, game consoles, personal computers, and others. Examples of V/A sinks include televisions, personal computers, projectors, audio devices, and others. Typically, standardized interfaces, in the form of cables, are used to communicatively couple V/A sources to V/A sinks.

One such standardized interface is the High-Definition Multimedia Interface, more often referred to simply as HDMI. An HDMI interface generally consists of two identical connectors attached to opposite ends of a cable. The cable typically includes seven (7) twisted pairs of copper wires for communicating various information. Four of the twisted wire pairs are adapted to communicate relatively high-speed data in the form of Transition Minimized Differential Signaling (TMDS). Of the four, three pairs are used for communicating video, audio, and auxiliary data, and are typically referred to as D1-D3. The other pair is used for transmitting a clock associated with the data, and is typically referred to as CLK. The speed of the high-speed data may range from 3 to 10 gigabytes per second (GPS).

The remaining three wire pairs are used for communicating relatively low-speed data, such as in the range of 100 kilobits per second (kbit/s) to 400 kbit/s. Two of such wire pairs are referred to as Display Data Channel (DDC) for providing communication between devices using a communication channel that adheres to an I²C bus specification. As an example, a V/A source may use the DDC to learn the video/audio format used by a corresponding V/A sink. One of the DDC wire pair, typically referred to as DDC DATA, is used to communicate data between the devices. The other DDC wire pair, typically referred to as DDC CLK, is used to transmit a clock associated with the data.

The remaining twisted wire pair for low-speed data is used for communicating remote control commands between the devices. Such data channel is typically referred to as Consumer Electronics Control (CEC). The CEC channel allows a user to use a single remote to control multiple devices coupled together via HDMI cables. More specifically, a unique address is assigned to the connected group of devices, which is used for sending remote control commands to the devices.

A drawback of the conventional HDMI is that length of the cable is typically limited to a relatively short distance. This is because distortion of the signal propagating through a twisted wire pair is significantly dependent on the length of the cable. At large lengths, the distortion of the signal may be so significant that the signal may not be able to be properly received by a V/A sink.

Optical communication systems use modulated optical electromagnetic energy or light to communicate information from one device to another. In such systems, one or more optical fibers are used to communicatively couple the devices. Further, at the transmission-side of such communication systems, an optical modulator is employed to modulate information in the form of an electrical signal onto optical energy. Typically, one or more vertical-cavity surface-emitting lasers (VCSELs) are used to perform the modulation. Similarly, at the reception-side of such communication systems, an optical demodulator is employed to demodulate information on the optical energy to produce an information-bearing electrical signal. Typically, one or more photo detectors (PDs) are used to perform the demodulation.

A VCSEL of an optical transmitter should be optically aligned with a corresponding optical waveguide or fiber in order for the optical signal to be efficiently coupled to the optical waveguide or optical fiber for transmission. Similarly, a PD of an optical receiver should be optically aligned with a corresponding optical waveguide or optical fiber in order to efficiently receive or detect the optical energy being received via the optical waveguide or optical fiber. Additionally, with regard to both VCSEL and PD, bias voltage needs to be provided to the devices in order for them to function.

Accordingly, there is a need for an HDMI or other data interface that is able to achieve lower signal distortion through the cable, thereby allowing the cable to be longer without significantly affecting the signals. Additionally, there is a need for such an interface to provide power as well. Further, there is a need to provide an indication power is available from either a V/A source or a V/A sink.

There is also a need for a mechanical assembly or mount to provide effective alignment of a VCSEL or PD with a corresponding optical waveguide or optical fiber, while at the same time, effectuating the necessary electrical routing for providing a bias voltage to such device.

SUMMARY

An aspect of the disclosure relates to a data communication cable medium, comprising a cable with optical waveguides for carrying relatively high-speed data from a high speed data source (e.g. DVD players, Blu-ray players, set-top boxes, camcorders, game consoles, personal computers, and others) to a high speed data sink (e.g. televisions, personal computers, projectors, audio devices etc).

In another aspect of the disclosure, the cable medium comprises one or more optical waveguides to carry the relatively high speed data and one or more wire mediums to carry relatively low speed data. An example of relatively high speed data is the TMDS data of an HDMI interface. An example of relatively low speed data is the DDC data and clock, and CEC of an HDMI interface. The cable medium may include a pair of multiplexer/demultiplexer at respective ends of the cable to multiplex and demultiplex two or more of the relatively low-speed data types to and from one or more wire mediums.

In another aspect of the disclosure the cable medium comprises one or more optical waveguides for carrying the relatively high speed data and one or more separate optical fibers for carrying relatively low speed data. Arbiters at both ends of the cable may prevent collision of the low-speed data, as the low speed data may be sent bi-directionally.

In summary, the data communication cable medium 100 comprises a plurality of optical waveguides (e.g., optical fibers) through which relatively high-speed data (e.g., the TMDS data of an HDMI interface) are communicated, and a plurality of electrical wires through which relatively low-speed data (e.g., DDC data and clock, and CEC of an HDMI interface) are communicated. The optical waveguides result in substantially less signal distortion of the high-speed data, thereby allowing the cable medium 100 to achieve much higher lengths without significantly affecting the high-speed signaling.

More specifically, with reference to FIG. 1, the data communication cable medium 100 comprises a cable 120, a first connector 110 coupled to an end of the cable 120, and a second connector 140 coupled to an opposite end of the cable 120.

Although an HDMI interface is used to exemplify the configuration of the data communication cable medium 100, it shall be understood that the cable medium 100 may be adapted to transmit high- and low-speed data of other protocols using the combination of optical waveguides and wires. Further, although the optical modulator 112 and multiplexer/demultiplexer 114 have been described as being incorporated into the first connector 110, it shall be understood that these components may be housed separately from the first connector, such as in a separate housing situated between the first connector 110 and the cable 120.

FIG. 8 illustrates a schematic/block diagram of an exemplary data communication cable medium 800 in accordance with an aspect of the disclosure. In summary, the data communication cable medium 800 comprises a plurality of optical waveguides (e.g., optical fibers) through which relatively high-speed data (e.g., the TMDS of an HDMI interface) and relatively low-speed data (e.g., DDC and CEC data of an HDMI interface) are communicated. The optical waveguides result in substantially less signal distortion of the high-speed data, thereby allowing the cable medium 800 to achieve much higher lengths without significantly affecting the high-speed signaling.

In particular, with reference to FIG. 8, the data communication cable medium 800 comprises a cable 820, a first connector 810 coupled to an end of the cable 820, and a second connector 840 coupled to an opposite end of the cable 820.

Additionally, the frame or housing includes one or more electrically-conductive traces extending from proximate the one or more thru-holes on a front side of the frame or housing to a bottom side of the frame or housing. The portion of the one or more electrically-conductive traces on the bottom side of the frame or housing are configured to make electrical contact with corresponding one or more electrically-conductive traces on a printed circuit board (PCB) or substrate, respectively. Accordingly, the optical communication mount 100 is configured as a surface-mount device. The one or more electrically-conductive traces facilitate routing one or more bias voltages from a driver circuit mounted on a PCB or substrate to the one or more PDs and/or VCSELs situated proximate the one or more thru-holes of the frame or housing.

More specifically, with reference to FIG. 15, the optical communication mount 1500 comprises a frame or housing 1502 including one or more thru-holes 1504. The frame or housing 1502 may be formed of a substrate, such as a semiconductor or electrical-insulating substrate. Accordingly, the one or more thru-holes 1504 may be configured as one or more via holes formed through the semiconductor or electrical-insulating substrate 1502.

FIG. 17A illustrates a perspective view of a photo detector (PD) and/or vertical-cavity surface-emitting laser (VCSEL) array device 1700 in accordance with another aspect of the disclosure. The PD and/or VCSEL array device 1700 may be configured to interface with the optical communication mount discussed above.

In particular, the PD and/or VCSEL array 1700 comprises a housing 1702 including an array 1704 of PDs and/or VCSEL devices. For example, all of the devices in the array 1704 may be PDs. In such configuration, the array device 1700 may be configured as a receiver. Alternatively, all of the devices in the array 1704 may be VCSELs. In such configuration, the array device 1700 may be configured as a transmitter. Alternatively, some of the devices in the array 1704 may be VCSELs and other devices in the array may be PDs (e.g., two VCSELs and PDs). In such configuration, the array device 1700 may be configured as a transceiver.

As shown, each device of the array 1704 may comprise an active area 1706, a grounding area 1708, and an electrically-conductive trace 1710 for routing a bias voltage or current to the active area. When the array device 1700 is interfaced with the optical communication mount, the active area 1706 of each device of the array 1704 registers with a thru-hole of the optical communication mount. Additionally, when the array device 1700 is interfaced with the mount, the electrically-conductive trace 1710 makes electrical contact with a corresponding electrically-conductive trace of the mount. As an example, with reference to FIGS. 16 and 17A, a bias voltage or current for a device of the array 1704 may be routed from a driver 1640 to the active area 1706 of the device via an electrically-conductive trace 1612 on the PCB or substrate 1610, an electrically-conductive trace 1626 on the mount 1620, and the electrically-conductive trace 1710 on the array device 1700.
