1. Los: Alarm for signal lossIt indicates that the local end cannot receive light or electrical signals. When the signal amplitude remains below a preset threshold value (the threshold value is very small, far lower than or equal to 10-3) within a given time (for example, 100 ms, the SDH device enters the Los state. If two consecutive valid frame locating patterns are detected and no los is detected, the SDH device should exit the Los state.(1) optical port los:Network Management alarm: Light re

connected to a control display module with wireless transceiver function to form an independent device, therefore, the power consumption and volume of each module are greatly reduced. The patient can select different modules based on different needs. The LCD display on each module can display the measurement signal in real time. All these modules interact with the host machine through wireless information. The PC can register a unique serial number f

transmission distance can reach 50 m at Gbps. parallel Optical Communication supports parallel transmission of multiple light sources, which can achieve long-distance transmission at a high bit rate ,. this is one reason for parallel optical interconnection. Parallel Optical module and Band Optical Cable Parallel Optical Interconnection is achieved through parallel optical modules and band optical cables. the parallel optical module is based on VCSEL arrays and PIN arrays, with a wavelength of

Article title: ZK-ID6USB infrared has been successfully used in Linux. Linux is a technology channel of the IT lab in China. Includes basic categories such as desktop applications, Linux system management, kernel research, embedded systems, and open source. Compared with the infrared transmitters integrated in the notebooks of major manufacturers, this independent USB port transmitter is difficult to drive in Linux, but it is still successful. The following describes how the IRDA subsystem works
