Description

Technical Field

[0001] This utility model relates to optical signal transmission technology and its equipment, specifically, a laser with voltage divider resistors. Background Technology

[0002] The optical communication module is the core component of an optical communication system, responsible for converting photoelectric signals to enable long-distance, electromagnetic interference-resistant, and lightweight data transmission. Optical transceivers and their driving circuits are the core components of the optical communication module.

[0003] Since the operating voltage of lasers in optical transceivers is typically 1.2–2.0V, while the driving voltage of optical modules is generally 5V, voltage divider resistors are usually required in the driving circuit of optical modules. This increases the size of the driving circuit and the difficulty of board modification, especially for some products with fixed dimensions and circuit structures, increasing the difficulty of electro-optical conversion. Furthermore, because end users are not very familiar with the operating characteristics of lasers, improper matching of the voltage divider and current limiting resistors may damage the laser; independent lasers have relatively low electrostatic discharge (ESD) ratings, and human discharge during operation can also damage the laser.

[0004] Therefore, it is necessary to provide a laser with voltage divider resistors. Utility Model Content

[0005] The purpose of this invention is to provide a laser with a voltage divider resistor.

[0006] The technical solution is as follows:

[0007] A laser with voltage divider resistors includes a laser body, which includes a laser chip. A voltage divider component is provided corresponding to the laser chip. The voltage divider component is composed of surface-mount resistors. The resistance value of the surface-mount resistors is calculated by considering the voltage drop of different lasers and driving circuits. The surface-mount resistors are selected and a quick-change resistor setting structure is formed by surface mounting. The surface-mount resistors are connected to the laser chip in series and serve as functional components for the laser's anti-static and anti-power surge protection, forming a safe and reliable laser structure.

[0008] Furthermore, the laser body is provided with a mounting area for mounting surface-mount resistors.

[0009] Furthermore, the corresponding area is located on the packaging socket of the optical device.

[0010] Furthermore, the corresponding area is located on the base of the laser.

[0011] Furthermore, surface mount resistors are directly attached to the corresponding mounting area using adhesive.

[0012] Furthermore, surface-mount resistors are connected in series with the laser chip via bonding.

[0013] Compared with the prior art, this utility model enables the laser to directly have voltage division and current limiting functions by using a series resistor in the laser chip, thereby simplifying the driving circuit, reducing the matching difficulty for end users, and improving the ease of use, reliability and compatibility of the product.

[0017] The surface mount resistor 20 is a resistance value calculated by different lasers and driving circuits. It is an option to obtain the resistance value and form a quick-change resistor setting structure by surface mounting.

[0018] The surface mount resistor 20 is connected in series with the laser chip 1 to serve as a functional component for the laser's anti-static and anti-power surge protection, forming a safe and reliable laser structure.

[0019] The laser body 100 is provided with a mounting area 3 for mounting surface mount resistors.

[0020] One configuration involves attaching the corresponding area 3 to the packaging socket of the optical device.

[0021] There are also other setting methods, such as attaching the corresponding area 3 to the base of the laser.

[0022] The surface mount resistor 20 is directly attached to the corresponding mounting area using adhesive.

[0023] The surface mount resistor 20 is connected in series with the laser chip 1 via bonding.

[0024] Compared with the prior art, this utility model enables the laser to directly have voltage division and current limiting functions by using a series resistor in the laser chip, thereby simplifying the driving circuit, reducing the matching difficulty for end users, and improving the ease of use, reliability and compatibility of the product.

[0025] For those skilled in the art, various modifications and improvements can be made without departing from the inventive concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
