The bandwidth of the optical transceiver refers to the frequency range in which the optical transceiver can actually work normally. The unit is usually Hz (hertz). Generally, the larger the range, the stronger the theoretical adaptability of the optical transceiver. For example, the video bandwidth of a certain video/audio optical transceiver is 2Hz～10MHz, and the audio bandwidth is 40Hz～20KHz, which reflects a strong dynamic width. Signal-to-noise ratio (SNR: SignalToNoiseRatio) refers to the ratio between the maximum undistorted sound signal intensity produced by the audio source of the optical transceiver and the noise intensity emitted at the same time. It is usually expressed in S/N, and generally in decibels (dB). The higher the signal-to-noise ratio, the better the audio quality. Generally, the signal-to-noise ratio of the audio optical transceiver should be above 60dB. Bit Error Rate (BER: BitErrorRatio) is an index that measures the accuracy of data transmission within a specified time. Bit error rate = bit errors in transmission/total number of codes transmitted*100%. If there is a bit error, there is a bit error rate. The signal level (signallevel) refers to the power ratio of the output signal and the input signal of the device and then takes the logarithmic value, usually expressed by P, P=lgP2/P1. Signal Impedance (SignalInpedance) refers to the ratio of the voltage to the current of the input signal, and the unit is usually Ω (ohm). Since the unit is ohm, it also applies to Ohm's law, that is, under the same voltage, the higher the impedance, the less current will flow, and the lower the impedance, the more current will flow. Optical power refers to the work done by light in a unit of time. Optical power units are usually expressed in milliwatts (mw) and decibels (db). The relationship between the two is: 1mw=0db. Decibels less than 1mw are negative. The conversion formula is P(dB)=10lgP(mW) ATM is an abbreviation for asynchronous transfer mode. A packet switching and multiplexing technology based on cells. It is a universal connection-oriented transmission mode designed for multiple services. It is suitable for local area networks and wide area networks. It has high-speed data transfer rates and supports many types of communications such as voice, data, fax, real-time video, CD quality audio and image.
