产品描述
本2路百兆以太+4路RS232/422/485 光纤收发器是以太网IEEE802.3介质转换器,能够实现2口10/100base-T 双绞线以太网+4路RS232/422/485 串行数据到光纤的介质转换或延伸网络传输距离,与光纤以收发器(以太网光端机)一样,RS485光猫被广泛应用在各种工业场合,
前者是计算机联网,后者应用在工业控制,一卡通,仪器仪表等,在众多工程项目里,两种设备的需求时同时存在的,本公司适时推出一款光纤传输设备,可以同时拥有2路共享10/100M网口和4路RS232/433/485接口,并且仅通过一芯光纤传送,既节省光纤资源,也节省光纤设备,减少故障点,方便了设备的维护。广泛应用于高清网络视频监控的应用与其它需要其它两种数据接口的场合。
