1.1功能概述 
1.1 Function Overview 

沈阳广成科技有限公司GCAN-208系列模块是集成1路（或2路）标准光纤接口（单模、多模，SC、ST、FC可选）、2路（或1路）标准CAN总线接口的工业级CAN总线转光纤转换器。 
The GCAN-208 series module from Shenyang Guangcheng Technology Co., Ltd. is an industrial grade CAN bus to fiber converter that integrates 1 (or 2) standard fiber optic interfaces (single-mode, multi-mode, SC, ST, FC optional) and 2 (or 1) standard CAN bus interfaces. 

GCAN-208系列模块可将CAN总线数据透明、无损的转换成光信号，再将光信号透明、无损的解析成CAN总线数据。广成科技使用独有的总线信号转换技术，可将CAN数据与光信号之间的转换时间做到微秒级，这样就保证了通信的实时性，GCAN-208可支持任何CAN总线通信协议如：CANopen、SAE J1939、DeviceNet、NMEA2000等等。 
The GCAN-208 series module can transparently and non destructively convert CAN bus data into optical signals, and then transparently and non destructively parse the optical signals into CAN bus data. Guangcheng Technology uses unique bus signal conversion technology to achieve microsecond level conversion time between CAN data and optical signals, ensuring real-time communication. GCAN-208 can support any CAN bus communication protocol such as CANopen, SAE J1939, DeviceNet, NMEA2000, etc. 

GCAN-208-1模块独特的双通道设备可以同时延长两条CAN总线的通信距离，GCAN-208-2模块具有两套光纤接口，可用于级联。该系列模块是工业总线改造、长距离通信、隔离总线干扰的关键性工具，模块的CAN总线接口已集成隔离保护模块，使其避免由于瞬间的过压过流而对模块造成损坏，可以防止总线受到电磁干扰、地环干扰、雷击等对总线和设备造成的损坏。 
The unique dual channel device of GCAN-208-1 module can simultaneously extend the communication distance of two CAN buses, while GCAN-208-2 module has two sets of fiber optic interfaces that can be used for cascading. This series of modules is a key tool for industrial bus transformation, long-distance communication, and isolation of bus interference. The CAN bus interface of the module has integrated an isolation protection module, which prevents damage to the module due to instantaneous overvoltage and overcurrent, and can prevent damage to the bus and equipment caused by electromagnetic interference, ground loop interference, lightning strikes, etc.
