Abstract
The present application discloses a control method, device, device and storage medium for an indicator light of an optical module. The method includes: firstly, the indicator light of the optical module is lighted through a PWM signal output by a CPLD or FPGA logic, and the PWM signal is at a high level at this time. ; Then, by adjusting the duty ratio of the PWM signal, the luminous brightness of the LEDs of different colors in the indicator light of the optical module are respectively controlled to achieve the desired synthesized color of the indicator light of the optical module; when the PWM signal is at a low level, by controlling the low-level LED Time to control LED afterglow to control the brightness of LEDs of different colors. In this application, the color adjustment of the indicator light of the switch optical module is realized through CPLD or FPGA logic programming and LED afterglow effect. The PWM signal is the signal source for color matching, that is, the color displayed by the indicator light is determined by the PWM signal. The debugging range is wide and can be adjusted. Continuous adjustment.
Description
technical field [0001] The invention relates to the field of network security, in particular to a control method, device, equipment and storage medium for an indicator light of an optical module. Background technique [0002] With the development of information technology, communication security technology is developing in a more accurate and faster direction. The increase in the rate of the optical port of the switch also brings compatibility with high and low-speed performance. For example, the 25G optical module can be backward compatible with 10G transmission. The two transmission rates of the same interface require that the optical port indicator can distinguish the two transmission rates, and the LINK and ACT statuses must still be indicated. [0003] Usually, the indicator of the optical port uses green and red two-color indicators. When the optical module is running on the 25G interface, the green indicator is always on to indicate the LINK status, and the 25G inter...
