[0027] Referring to FIG. 1, which shows an embodiment of a hybrid cable 100 according to the present invention. FIG. 1 shows a near-end part of the hybrid cable 100 wherein several lines 110 can be seen extending from the end of the hybrid cable 100. The hybrid cable includes an external jacket which encloses the lines 110. FIG. 1 shows four optical fiber connectors connected to four optical fiber lines and a plug 130 connected to seven electrical lines. The four optical fibers 120 and the plug 130 can be connected to an optical transmitter shown in FIG. 2. The optical transmitter can be a part of an optical transmission system which also includes a similar optical receiver.

[0028] FIG. 2, shows a perspective view of an optical transmitter 200 according to one implementation of the present invention. The optical transmitter 200 is shown to include a housing 210 enclosing a transmitting circuitry and laser. The optical transmitter 200 provides for high bandwidth data transfer over long distances, for example, 1000 feet and more without any lag. The optical transmitter 200 can transfer full speed uncompressed video data through optical fiber cables. Referring to FIG. 1, four optical connectors 220 can be seen extending from the housing 210. The optical connectors 220 can be removably connected to the four optical connectors 120 shown in FIG. 1. In one case, the optical connectors can be an LC OM3 connector, as shown in FIG. 1, that is both economical and readily available. Furthermore, can be seen in FIG. 2 is a socket 250 having seven electrical pins. The plug 130 shown in FIG. 1, can be connected to the socket 250 for electrical connectivity between the optical transmitter and the optical receiver. The plug 130 is also having seven pins which electrically connect to the socket 250 of the optical transmitter. The optical transmitter is further shown to have an HDMI port 250 for connecting to a sink device, such as a TV, projector, or monitor. The four connectors 220 in FIG. 2 also extends from four optical fiber lines 230 that connect the four connectors 220 to the transmitting circuitry of the optical transmitter.

[0029] FIG. 1 further shows six additional optical connectors 140 that can connect to the media device for transmitting data as light signals. Two Toslink lines with Toslink connectors 150 can also be seen in FIG. 1. Additionally, an Aux cable 160 can also be seen extending from the hybrid cable 100.

[0030] FIG. 3 shows another implementation of the hybrid cable 300 which includes a hybrid cable part 310 and an HDMI connector 320 that is shown connected to the hybrid cable part 310. The hybrid cable part 310 can include a proximal end and a distal end. FIG. 3 shows the proximal end of the hybrid cable part 310. The distal end of the hybrid cable part 310 can be the same or different from the proximal end. The hybrid cable part 310 in addition to the lines of HDMI connector 120, also encloses nine additional lines 330. These nine lines can be seen extending from the proximal end of the hybrid cable part 310. The part of lines being extended from the proximal end of the hybrid cable part 310 can be herein referred to as the extended part of the line. Six of the nine lines 330 are shown to connect with optical fiber connectors 340. These optical fiber lines can be used to transmit high bandwidth data as light signals. Two of the nine lines 330 are shown to connect with Toslink connectors 350 for high-quality audio transmission. Additionally, an Aux cable line 360 is also shown included in the hybrid cable 300.

[0031] FIG. 3 further shows that each extended part of the nine lines extend from the proximal end is having a length different from the other extended part of lines. For example, the length of extended parts of the line increase in ascending order, wherein one of five optical fiber line is of shortest length, while the other four optical fiber lines gradually increase in length. The extended part of the Toslink line 350 is having a length larger than that of the extended part of the optical fiber lines 340. The two Toslink line 350 are also of different lengths. The Aux cable line 360 is shown to have the largest length among the extended parts of the nine lines 330. Such an arrangement of the cable lines extending from an end of the hybrid cable resembles a ponytail, wherein each strand of the ponytail is different from the lengths of the other strands. Such an arrangement of the extended part of cable lines is advantageous by preventing a clutter of connectors, which is bulgy, the connectors keep colliding with each other, and causes tangling of the wire lines. The hybrid cable 100 shown in FIG. 1 is also having a similar ponytail like arrangement of the extended parts of the cable lines. It is to be noted that any cable line can be of a length larger or smaller than the other lines. Although both FIGS. 1 and 3 shows the Aux cable line of largest length, the Aux cable line can also be of the smallest length.
