Specifically, these adapters 107 typically do not have any optical design and performance, and complete a mirroring function in signals between different communication protocols, just for simple electronic and mechanical devices. .

FIG. 3 is a view showing one embodiment of the optical cable module of the present invention. The optical fiber cable 130 of this embodiment is connected to the connector 110 and used for transmission of optical signals. The optical fiber cable 130 includes at least one optical fiber core 131 and a covering layer 132.

It should be understood that each optical fiber core 131 includes a core and a cladding layer, so that an optical signal is transmitted in the core using a total reflection method. In various embodiments, since the end of the optical fiber core 131 is connected to the photoelectric unit 120 of the connector 110 through a jumper connector, the optical signal emitted by the laser (or LED) 121 of the photoelectric unit 120 The optical fiber core 131 of the cable 130 is transmitted.

FIG. 6 is a view showing a cross section of another embodiment of the optical fiber cable of the present invention. The material of the covering layer 132 is plastic, for example, epoxy resin or silicone rubber. The covering layer 132 includes at least one light transmitting part 133, and an optical signal in transmission in a small part in the optical fiber core 131 is transmitted to the outside by the light transmitting part 133.

The translucent part 133 has an inner surface 133a and an outer surface 133b facing each other. The inner surface 133a contacts at least the optical fiber core 131, and the outer surface 133b contacts the outside. Is emitted to the outside by the inner surface 133a and the outer surface 133b of the translucent part 133.

In the embodiment, since the laser (or LED) 121 emits at least one kind of visible light into the optical fiber core 131 of the optical fiber cable 130, the optical signal being transmitted in the optical fiber core 131 is transmitted through the covering layer 132. By being transmitted to the outside by the optical unit 133, the user can see it.
When an optical signal is transmitted through the optical fiber cable 130, light rays in a small part (weak) of the optical signal are always transmitted or scattered by the optical fiber core 131 into the coating layer 132. In particular, when the optical fiber cable 130 is bent during use, light rays in a small portion (weak) of the optical signal are more easily transmitted through the covering layer 132 by the bent portion of the optical fiber core 131. Therefore, in this embodiment, the weak light beam (visible light) transmitted through the coating layer 132 by the optical fiber core 131 is emitted to the outside by the light transmitting portion 133 of the coating layer 132, so that the user can see it. . As a result, the optical cable module 100 of the present embodiment can indicate its use state (for example, a working state for maintaining energization during signal transmission) by weak visible light leaking from the optical fiber core 131.

The material of the opaque portion 134 is the same as or different from the material of the transparent portion 133. The translucent part 133 and the non-translucent part 134 are arranged in various shapes or means. For example, as shown in FIGS. 4 and 5, the translucent part 133 and the non-translucent part 134 may be arranged on the covering layer 132 in a crossed and divided manner. Further, as shown in FIG. 6, in another embodiment, the cross-sectional shape of the non-translucent portion 134 is U-shaped, and the translucent portion 133 is fitted in the non-translucent portion 134.

The optical fiber core 131 is used for signal transmission, and the feeder line 136 directly transmits power. By aligning the feed line 136 within the fiber optic cable 130, the fiber optic cable 130 transmits power directly through the feed line 136, eliminating the need for excess external or power lines or power sources. Preferably, the feed line 136 is manufactured from a metal material having a high reflectivity, and at the same time, the mechanical strength of the optical fiber cable 130 is enhanced and the visible light leaking from the optical fiber core 131 is reflected, so that the covering layer 132 Since the light-transmitting portion 133 emits light to the outside, the user can see it. Since the light beam reflected by the feed line 136 is emitted to the outside by the translucent part 133, the inner surface 133a of the translucent part 133 is at least in contact with the optical fiber core 131 and the feed line 136, and the outer surface of the translucent part 133 By contacting 133b with the outside, the light beam reflected by the feeder 136 is emitted to the outside by the inner surface 133a and the outer surface 133b of the translucent part 133. Therefore, the visible light emitted by the optical fiber cable 130 is further clarified through the reflection effect of the feeder line 136, thereby increasing the beauty of the outer shape of the optical fiber cable 130, the presentation of the visual position, or the effect of warning. be able to. Furthermore, the strength of the structure of the optical fiber cable 130 can be enhanced by the metal strength of the feeder line 136. Accordingly, the cable width or diameter of the optical fiber cable 130 is further reduced, and at the same time, it has a predetermined mechanical strength, so that it is suitable for the application of consumer electronics products.

In one embodiment, the material of the feeder line 136 may be silver or a silver-containing alloy, and may be aluminum or an aluminum-containing alloy. Since the silver wire or the aluminum wire has a high reflectance, the feeder line 136 containing silver can assist the reflection of the visible color light leaking from the optical fiber core 131, and the visible light emitted from the optical fiber cable 130 can be reflected. Further, it is possible to increase the beauty of the outer shape of the optical fiber cable 130, the presentation of the visual position or the effect of warning.

As shown in FIG. 8, in one embodiment, the plurality of coating layers 132 can cover the plurality of optical fiber cores 131.

In various embodiments, preferably, the translucent portion 133 of the covering layer 132 is bendable. In the embodiment, the flexibility of the translucent part 133 is larger than the flexibility of the non-translucent part 134, that is, the translucent part 133 is more easily curved than the non-translucent part 134. Therefore, when the optical fiber cable 130 is bent during use, the weak light beam of the optical signal can be easily emitted from the light transmitting portion 133 of the coating layer 132 to the outside. In this example, for example, a different material or a different diameter is selected to form the light transmitting portion 133 and the light transmitting portion 134 having different flexibility.

In various embodiments, preferably, since the refractive index of the light transmitting portion 133 of the covering layer 132 is equal to or close to the refractive index of the cladding layer (Cladding) of the optical fiber core 131, light leaking from the optical fiber core 131 is easy. The light can be entered into the translucent part 133. In the embodiment, the difference in refractive index between the light transmitting portion 133 and the cladding layer of the optical fiber core 131 is smaller than the difference in refractive index between the light transmitting portion 134 and the cladding layer of the optical fiber core 131. Compared with the light transmitting part 134, the light beam leaking from the optical fiber core 131 can easily enter the light transmitting part 133. Therefore, when the optical fiber cable 130 is bent during use, the weak light beam of the optical signal is more easily emitted from the light transmitting portion 133 of the coating layer 132 to the outside. In this example, for example, different materials can be selected to form the light transmitting part 133 and the light transmitting part 134 having different refractive indexes.

Therefore, when no visible light signal is transmitted to the optical cable module 100, there is no leakage of visible light. Therefore, the translucent part 133 of the covering layer 132 is in a transparent state or a state in which the color is not changed, so that the user can It can be seen that the module 100 is in an unused state, that is, a state in which no signal is transmitted. Conversely, when transmitting an optical signal by the optical cable module 100, particularly when transmitting a signal by connecting to a morphological electronic product using the optical cable module 100, the weak visible light is transmitted by the light transmitting portion 133 of the covering layer 132. Since the light-transmitting part 133 appears in a different color after being launched, the user can know that the optical cable module 100 is in use, that is, a signal is transmitted. Thereby, the installation of the optical cable module 100 allows the user to easily understand the usage state. Further, the optical fiber cable 130 of the optical cable module 100 is changed to a different hue, and is applied to a consumer electronic product in particular in order to increase the beauty of its outer shape. Furthermore, the position of the optical cable, for example, in the dark light space, is represented to increase the position warning or presentation effect.

When the optical fiber cable 130 has a plurality of optical fiber cores 131, the optical fiber cable 130 of the optical cable module 100 uses a multiple wavelength to achieve a specific mixed light (or mixed optic color) effect. The effects of mixed light can be represented, which represents the specific transmission performance of the fiber optic cable 130 and allows multiple selection of individualized light color product designs.
