Embodiment Construction
[0023] see figure 1 , which is a structural schematic diagram of a light emitting subassembly with an oblique reflector in the present application;
[0024] Depend on figure 1 It can be seen that a light-emitting subassembly with an oblique reflector provided in the embodiment of the present application includes a detachably connected upper cover 1 and a base 2; wherein, the upper cover 1 and the base 2 can be connected in a variety of connection methods without limitation, for example Buckling, welding, screwing or other forms are not limited here. The base 2 is mainly used to carry and fix various parts of the light emitting subassembly, and the upper cover 1 is used to provide protection for these parts. In addition, both the upper cover 1 and the base 2 can be formed by one-piece die-casting or powder metallurgy, and the selection of specific materials should be considered to be commonly used materials in the field, and there is no limitation here.

The invention discloses a light emission sub-assembly with an oblique reflector. The light emission sub-assembly comprises an upper cover and a base which are detachably connected. The base comprises a bottom plate and a side plate; optical fiber socket assemblies are arranged on the sides, away from the bottom plate, of the side plates; a thermoelectric refrigerating unit is mounted on the bottom plate; a ceramic substrate, a laser diode, a lens and a monitoring diode are arranged on the thermoelectric refrigerating unit; the laser diode is mounted on the ceramic substrate; the axes of the laser diode, the lens and the optical fiber socket assembly are located on the same straight line. The monitoring diode is positioned on one side of a straight line where the laser diode and the lens are positioned; an oblique reflecting mirror is arranged above the ceramic substrate; the oblique reflector is used for reflecting the laser emitted by the laser diode to the monitoring diode. The oblique reflecting mirror is arranged in the light emitting sub-assembly, backlight can be reflected to the monitoring diode arranged on the side face, the problem that the wiring space is occupied due to the fact that the monitoring diode is arranged on the rear portion is solved, the connecting length is shortened, the speed is increased, and the cost is reduced.
Description
technical field [0001] The invention relates to the technical field of communication equipment, in particular to a light emitting subassembly with an oblique reflector. Background technique [0002] Transmitter Optical Sub-Assembly (TOSA) is a relatively common converter that converts electrical signals into optical signals. With the development of communication technology, the rate of optical transmission components is getting higher and higher. Single-channel 25G Optical transmission components with / 50G or even higher rates are becoming more and more common. Under the requirement of high speed, the requirements for the connection between the light emitting component and the electrical components are also increased. The shorter the connection and the straighter the layout, the more conducive to the realization of high speed. [0003] However, due to the configuration of traditional light emitting components and other related parts, it is difficult to shorten the connectio...
