Embodiment Construction

[0017] In order to make the technical problems, technical solutions and advantages to be solved by the embodiments of the present invention clearer, the following will describe in detail with reference to the drawings and specific embodiments.

[0018] Existing multi-directional optical components often use parallel light to extend the distance, and a convex lens with real focus is used to obtain parallel light. Such as figure 1 Shown is a schematic diagram of an optical component using a real focal point convex lens in the background technology. However, the convex lens with real focus takes up a lot of space, which makes it difficult to assemble optical components and optical modules. Embodiments of the present invention aim at the problems existing in the prior art, and provide a multidirectional optical component, including: a first light emitting component, a light receiving module, a light transmitting module, and an optical fiber component;

[0019] Wherein, the light...

Abstract

The invention provides a multi-direction light assembly, which comprises a first light transmitting assembly, a light receiving module, a light transmitting module and an optical fiber assembly, wherein the light receiving module at least comprises a first light receiving assembly, a first filter and a concave lens; the light transmitting module at least comprises a second light transmitting assembly, a second filter and a convex lens; and incident light transmitted by the first light transmitting assembly is transmitted and reflected via the light receiving module and the light transmitting module, and multi-direction emergent light can be obtained. The concave lens with a virtual focus is used for replacing a convex lens with a real focus commonly used in the prior art for carrying out transmission to obtain parallel light, and thus the multi-direction light assembly which can effectively reduce the light assembly length and increase the available space of the inner circuit of the light module can be obtained.

Description

technical field [0001] The invention relates to the technical field of optical communication, in particular to a multi-directional optical component. Background technique [0002] With the development of the optical communication technology industry, users' demand for bandwidth is increasing day by day. In the PON (Passive Optical Network, passive optical network) system, due to the different bandwidth requirements of users, different bandwidths need to be compatible in the same optical network, so multi-directional optical components such as three-way and four-way are required. [0003] At present, FTTx (Fiber-to-the-x, optical fiber access) network is laid on a large scale. In order to locate optical network faults efficiently, quickly and at low cost, the optical components of the original OLT (Optical Line Terminal, optical line terminal) On the basis of the OTDR (Optical time-domain reflectometer, Optical Time Domain Reflectometer) function is added to detect light, an...
