信源汇聚单元一般都是三层交换机或者三层以上的交换机。核心层是全光网络的主干部分，保障整个网络性能，是AOC全光网的管理设备，核心层交换机的主要目的在于通过高速转发通信，提供快速、可靠的骨干传输结构，因此核心层交换机应该具有如下特性：可靠性、高效性、冗余性、容错性、可管理性、适应性、低延时性等。

The source aggregation unit is generally a Layer 3 switch or more than a Layer 3 switch. The core layer is the backbone of the all-optical network, ensuring the performance of the entire network, and is the management equipment of the AOC all-optical network, and the main purpose of the core layer switch is to provide a fast and reliable backbone transmission structure through high-speed forwarding communication, so the core layer switch should have the following characteristics: reliability, high efficiency, redundancy, fault tolerance, manageability, adaptability, and low latency.

光收发模块的工作原理主要基于光电转换和电光转换过程。在发送端，光模块接收电信号，通过内部驱动芯片处理后，驱动半导体激光器（LD）或发光二极管（LED）发射出相应速率的调制光信号。这些光信号随后通过光纤进行传输。在接收端，光模块将接收到的光信号通过光探测二极管转换成电信号，并经过前置放大器处理后，输出相应码率的电信号

The working principle of the optical transceiver module is mainly based on the photoelectric conversion and electro-optical conversion processes. At the transmitter end, the optical module receives the electrical signal, processes it through the internal driver chip, and drives the semiconductor laser (LD) or light-emitting diode (LED) to emit a modulated optical signal at a corresponding rate. These optical signals are then transmitted via optical fibers. At the receiving end, the optical module converts the received optical signal into an electrical signal through the optical detection diode, and outputs the electrical signal of the corresponding bit rate after being processed by the preamplifier
