Description

Technical Field

[0001] This utility model relates to the field of optical amplifier technology, specifically to a standardized amplification unit structure. Background Technology

[0002] In current amplifier designs, different optical structures and devices are used to meet different performance requirements and application scenarios. These include single-stage amplification, two-stage amplification, or multi-stage amplification structures; different pump injection methods; fixed amplification gain or adjustable amplification gain; and adjustments to other detailed components to meet additional mechanical size and optical performance requirements.

[0003] In this situation, although many optical components have certain standards, the production of each amplifier requires manual soldering and placement, fiber optic splicing, and other labor-intensive processes due to differences in their placement on the PCB board and the amount used. Moreover, the stability of production can fluctuate depending on the operator's skill level. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide a standardized amplification unit structure to improve production efficiency and stability while retaining design flexibility.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A standardized amplifier unit structure includes a mechanical housing, erbium fiber, a pump source, an input fiber, and an output fiber;

[0007] The mechanical housing has a hollow groove in the middle;

[0008] The pump source has a built-in combiner, and the pump source is placed in a hollow slot in the mechanical housing;

[0009] The mechanical housing is provided with a mechanical guide rail that surrounds the outside of the hollow groove, and the erbium fiber is coiled in the mechanical guide rail;

[0010] The input optical fiber is connected to the input port of the pump source and serves as the optical interface for signal input.

[0011] One end of the output optical fiber is connected to the output port of the pump source, and the other end of the output optical fiber is connected to one end of the erbium fiber, with the other end of the erbium fiber serving as the optical interface for signal output.

[0012] Furthermore, the pump source is a surface-mounted or perforated pump source.

[0013] Furthermore, the other end of the output optical fiber is connected to one end of the erbium fiber by fusion splicing or coating.

[0014] Furthermore, the pump source is connected to a pin that extends to the outside of the mechanical housing, which serves as the electrical interface for the entire amplification unit.

[0015] Furthermore, the pump source dissipates heat through contact with the mechanical housing via a thermally conductive pad.

[0016] Furthermore, one end of the mechanical housing is connected to screws for securing the entire amplification unit.

[0017] Furthermore, to meet different amplification gain requirements, only the length of the erbium fiber inserted into the coil needs to be adjusted, resulting in various customized amplification units.

[0018] Furthermore, by cascading amplification units with different gains, the requirements for complex optical path amplifiers can be met, further expanding the scope of application.

[0019] Furthermore, the pump source is a wide-temperature-range uncooled pump, and the erbium fiber is coiled above the heat dissipation teeth of the uncooled pump.

[0020] This invention adopts the above technical solution, redefining the standardized amplification unit by merging optical functions and fixing the manufacturing process. This enables the pre-preparation of the core unit, improving production efficiency and increasing production stability due to the standardization of steps. Simultaneously, the combination of different standard units retains the flexibility of amplifier design, maximizing the balance between different application scenarios and usage requirements. Attached Figure Description

[0021] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments:

[0022] Figure 1 This is a front view of the standardized magnification unit of this utility model;

[0023] Figure 2 This is a top view of the standardized enlarged unit of this utility model;

[0024] Figure 3 This is a schematic diagram of a complete amplifier design (the upper part of the diagram shows a single amplification unit, and the lower part shows a schematic diagram of two amplification units cascaded together). Detailed Implementation

[0025] like Figure 1-2 As shown, this utility model discloses a standardized amplification unit structure, including a mechanical housing 1, an erbium fiber 2, a pump source 3, an input optical fiber 4, and an output optical fiber 5.

[0026] The mechanical housing 1 has a hollow groove in the middle; the pump source 3 is a label-type pump source or a perforated pump source, and the pump source 3 has a built-in wave combiner. The pump source 3 is placed in the hollow groove of the mechanical housing 1; the pump source 3 dissipates heat by contacting the mechanical housing 1 through a thermal pad.

[0027] The mechanical housing 1 has a mechanical guide rail that surrounds the outside of the hollow groove, and the erbium fiber 2 is coiled in the mechanical guide rail.

[0028] The input fiber 4 is connected to the input port of the pump source 3 as an optical interface for signal input;

[0029] One end of the output optical fiber 5 is connected to the output port of the pump source 3, and the other end of the output optical fiber 5 is connected to one end of the erbium fiber 2 by fusion splicing or coating. The other end of the erbium fiber 2 serves as the optical interface for signal output.

[0030] The pump source 3 is connected to a pin 6 that extends to the outside of the mechanical housing 1. This pin 6 is the electrical interface for the entire amplification unit.

[0031] One end of the mechanical housing 1 is connected to a screw 7 for securing the entire amplification unit.

[0032] like Figure 3 As shown, a complete amplifier design can be achieved using one or through multiple cascades. When multiple amplifiers are cascaded, optical components such as input / output photodetectors 8 and adjustable optical attenuators 9 can be added to the input and output terminals of each amplification unit, thus maintaining design flexibility for different requirements.

[0033] In another implementation, the pump source in this invention employs a wide-temperature-range uncooled pump, with the erbium fiber directly wound above the heat dissipation teeth of the uncooled pump, eliminating the TEC or heating circuits found in existing designs. By utilizing the temperature insensitivity of this type of pump in high and low temperature environments, and by rationally utilizing the additional heat generated during the operation of the pump laser to provide auxiliary heating for the erbium fiber, the power consumption of the amplifier itself is greatly reduced, achieving optimization of both performance and power consumption.

[0034] The specific embodiments of this utility model have been described above. However, those skilled in the art should understand that this is only an example. Those skilled in the art can make various changes or modifications to this embodiment without departing from the principle and essence of this utility model, but all such changes and modifications fall within the protection scope of this utility model.
