定向耦合器是一种四端口无源器件，有一个输入端口，一个输出端口，一个耦合信号端口以及一个内部端接端口。定向耦合器用于将一条传输线中特定比例的传输功率通过另一个接口或端口进行耦合。从信号采样到信号生成和信号注入。
A directional coupler is a four-port passive device that has an input port, an output port, a coupled signal port, and an internal termination port. Directional couplers are used to couple a specific proportion of the transmitted power in one transmission line through another interface or port. From signal sampling to signal generation and signal injection.
耦合器是一种将一路输入信号能量分成两路或多路输出不相等能量的器件，耦合器的主要技术参数有功率损耗(包括插入损耗、耦合损耗)。
A coupler is a device that divides the energy of an input signal into two or more output unequal energy, and the main technical parameters of the coupler are power loss (including insertion loss and coupling loss).

The near-end optical transceiver converts the voice and data signals to be transmitted into photoelectric conversion, and then multiplexes these digital signals to convert multiple low-speed digital signals into a high-speed signal, and converts this signal into an optical signal. At the receiving end, the optical signals are converted into electrical signals, and finally these data signals are restored into voice and data signals.
定向耦合器有4个端口，两根传输线，传输线之间有一定的耦合，当功率由端口1向端口2传输时，如果端口2,3,4都接匹配负载，则副线上只有端口3有能量输出端口4无能量输出，称为同向定向耦合器，并称端口2为直通端口，3为男合端口，4为隔离端口。
The input signal of an optical transmitter (near-end unit) is a radio frequency (RF) signal. At the front end, the RF signal is sent to the optical transmitter input for electronically controlled attenuation, predistortion compensation and automatic power level control, and then the laser chip is driven for RF/optical modulation, and the RF signal is converted into an optical modulation signal.
耦合功分器端芯采用镀金工艺，使高频电流以最小的电流损耗传输，避免各个元器件大量衰减信号能量。
The end core of the coupling power divider adopts the gold plating process, so that the high-frequency current is transmitted with the minimum current loss, and the signal energy of each component is attenuated by a large amount.
