2．单通道光发送机最大输出功率为0dBm，光接收机的接收光功率不低于－26dBm，过载点为－10dBm。
3．可以采用EDFA 作为线路放大器，其中EDFA 的输入功率限制在－18～2dBm，最大输出功率20dBm，增益范围为13～25dB，噪声指数4.0dB。(Task: Design a 4 x 2.5 Gbit/s long-distance optical fiber transmission system, and use OptiSystem simulation to verify.
Requirement:
1. Using wavelength division multiplexing technology, the wavelength is set at 100GHz intervals, with frequencies of 193.1 THz, 193.2 THz, 193.3 THz and 193.4 THz, respectively. The transmission rate of each wavelength is 2.5 Gbit/s (NRZ), and the transmission distance is 300 km. The loss coefficient of conventional optical fibers is 0.25dB/km.
2. The maximum output power of a single-channel optical transmitter is 0 dBm, and the receiving power of an optical receiver is not less than -26 dBm, and the overload point is -10 dBm.
3. EDFA can be used as line amplifier, where the input power of EDFA is limited to - 18-2dBm, the maximum output power is 20dBm, the gain range is 13-25dB, and the noise index is 4.0dB.)
