3 Terms and definitions

The following terms and definitions apply to this document. 3.1 Optical devices used in optical fiber communications to realize modulated optical signal transmission, optical signal reception and optical signal transmission. Note. According to physical characteristics, optical devices for communication are divided into electro-optical devices, optoelectronic devices and optical-optical devices. 3.2 electro-optical deviceelectro-opticaldevice An optical device that converts input electrical signals into output modulated optical signals. Note. Such as directly modulated laser, electro-optical intensity modulator, etc. 3.3 Optoelectronic device opto-electricaldevice An optical device that converts input modulated optical signals into output electrical signals. Note. Such as avalanche photodiode, PIN photodiode, etc. 3.4 Optical device opto-opticaldevice The input is an optical signal and the output is still an optical device. Note. Such as semiconductor optical amplifier, optical amplifier, optical attenuator, optical coupler, etc. 3.5 S-parameterscatteringparameter Radio frequency and microwave frequency bands are used to characterize network parameters or characteristics. Note 1.For a two-port network, the S parameters are divided into S11, S21, S12, and S22, where S11 and S22 are reflection coefficients, and S21 and S12 are transmission coefficients. Note 2.For optoelectronic devices, pay attention to S21 and S22; for electro-optical devices, pay attention to S11 and S21; for optoelectronic devices, pay attention to S21. ......
