The optical engine often plays a crucial role in these devices and networks, and even the optical engine can be said to be a cardiac element of the optical communication device.
At present, in order to more fully satisfy the electrical space, the optical engine is usually manufactured by directly connecting optical fibers. The optical fiber direct connection means that in the production process of the optical engine, the optical fiber and the optical engine are fixed together to achieve the purpose of optical path transmission.
The scheme is the most common light engine manufacturing scheme, and has the advantages of simple structure, uncomplicated process and capability of saving space of the circuit board to a great extent. However, since the optical fiber is directly connected, the optical fiber itself is a vulnerable object, which causes great inconvenience in the storage and use of the light engine structure. Meanwhile, the optical engine often has several or even tens of optical fibers connected, and if 1 fiber is damaged in the process, the whole optical engine product is directly scrapped and is difficult to repair, and the later maintenance cost cannot be estimated.
In order to solve the above problems, the light engine is made into a pluggable packaging structure. Namely: an optical adapter is arranged in each optical unit of the optical engine, and the external optical fiber can be connected with the optical adapter through a standard optical fiber connector, so that the purpose of optical path transmission which is the same as the optical fiber direct connection is achieved.

Although the light engine with the above structure has a simple structure and a high degree of modularization, the optical fiber is made of glass material and is brittle, so that the optical fiber has toughness only by having a certain length, and if the optical fiber is too short, the optical fiber has large stress and is easy to break, and the optical fiber is easy to damage under the influence of temperature and vibration. In order to meet the requirement of the length of the optical fiber, the length design size of the optical unit must be large, and the required installation size of the main board needs to be large similarly to the optical module, which directly increases the design size of the whole optical engine. Therefore, there is a need to provide further solutions to the above problems.

Fig. 1 is a schematic structural diagram of an embodiment of a high space utilization optical engine mechanism according to the present invention.
Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
As shown in fig. 1, an embodiment of the present invention provides a light engine mechanism with high space utilization, which includes: a main board 1, a controller 2 and a number of light units 3.
Controller 2 and a plurality of optical unit 3 electric connection in the one side of mainboard 1, controller 2 is located the middle zone of mainboard 1 one side, and a plurality of optical unit 3 distribute in controller 2 week side, and each optical unit 3 of controller 2 arbitrary side sets up side by side.
Any of the light units 3 includes: an optical device 31 and an optical adapter 32. In order to make the optical fiber have a certain length and a larger bending radius, the optical device 31 of any optical unit 3 is connected with the optical adapter 32 of another optical unit 3 arranged at intervals along the arrangement direction of the row through the optical fiber 33, and the optical adapter 32 of any optical unit 3 is connected with the optical device 31 of another optical unit 3 arranged at intervals along the arrangement direction of the row through the optical fiber 33. With this arrangement, the optical fiber 33 is disposed outside the light units 3, so that the length of the optical fiber 33 is extended, and the extended optical fiber 33 mainly occupies the area between the controller 2 and each light unit 3 on the peripheral side thereof, thereby significantly improving the utilization ratio of the internal design space of the light engine.
Since in each light unit 3 of any row, two light units 3 that are spaced apart are connected by an optical fiber 33. In this way, the optical fibers 33 connecting the light units 3 spaced apart from each other can be made not to contact the controller 2 of the middle area, thereby achieving avoidance of interference with the main device area on the main board 1. Because the controller 2 generates a large amount of heat during operation, the controller 2 is bypassed, so that the heat dissipation of the controller is facilitated, and the operation reliability of the light engine is further ensured. At the same time, the way in which the optical fiber 33 connects the two spaced optical units 3 also allows this to have a curved design that maintains its own flexibility, thus ensuring the reliability of the optical fiber 33
In order to make each optical fiber 33 have the same length and reduce the production cost, the arrangement of the optical units 3 around the controller 2 needs to be optimally designed.
In one embodiment, any row of light units 3 are in contact with each other or arranged at equal intervals, and the two light units 3 arranged at intervals in each group can maintain a uniform interval, and accordingly, the lengths of the optical fibers 33 connecting the light units 3 in one row can also be maintained to be uniform. Thus, the optical fiber 33 with the standard length is beneficial to mass production, and the problems of difficult control and high defective rate caused by producing the optical fibers 33 with different specifications and lengths are avoided.
In a preferred embodiment, any row of light units 3 are in contact with each other or arranged at equal intervals, and the lengths of the optical fibers 33 connecting the light units 3 in each row are kept consistent, that is, the lengths of all the optical fibers 33 are kept consistent, so that a fully standardized design of the lengths of the optical fibers 33 is realized.
In one embodiment with a conventional arrangement, the controller 2 has four light units 3 arranged side by side on either side, and in any row of light units 3, the first and third light units 3, 3 in the first order are connected by optical fibers 33 and the second and fourth light units 3, 3 in the second order are connected by optical fibers 33 in the direction of the arrangement.
In order to facilitate the connection of the optical device 31 to the optical adapter 32, the optical adapter 32 also has an optical connector 34, by means of which the optical adapter 32 is connected to the corresponding optical device 31 by means of an optical fiber 33.
In addition, for any optical unit 3, the optical unit 3 further includes a circuit board 35, the circuit board 35 is electrically connected to the motherboard 1, and the optical device 31 and the optical adapter 32 are electrically connected to the circuit board 35. In one embodiment, the circuit board 35 is electrically connected to the motherboard 1 by means of an electrical connector or BGA soldering.
In summary, the optical engine of the present invention optimizes the connection relationship between the optical adapter and the optical device, so that the optical fiber has a certain length and a larger bending radius, thereby ensuring the reliability of the optical fiber, skillfully avoiding the interference with the main device area on the motherboard, and fully improving the utilization rate of the internal design space of the optical engine. The invention can make each optical fiber have the same length, the cost of mass production is low, the error is not easy to occur in the production process, and the invention is beneficial to simplifying the production process.
