            光发射机

            产品名称:野外性光发射机

            产品名称:Gatar-860P

            产品概述:

            Gstar-890 XXmw系列野外型1310nm 光发射机是一款在HFC宽带传输网络中能适应并满足野外工作环境的特种光传输设备。

             产品采用直接光强度调制方式,较低的射频信号工作输入电平要求,良好的密封和散热性能,使产品适用于各种恶劣的野外工作环境。

            在带宽860MHz工作频段内,传输容量大、非线性失真小等特点;

            自动光功率控制电路、自动激光器温度控制电路、激光器?;さ缏芳凹す馄髀舳缏房捎行а映ぜす馄鞯墓ぷ魇倜捅Vぜす馄鞒て诠ぷ魇笔涑龉夤β实奈榷ㄐ?。
                  此光发射机预失真电路使产品具有优异的非线性指标,以确保光纤网络多级级联和长距离传输,实现远程的用户覆盖。
            产品内带有微处理器电路以及内嵌VFD,用于监测和显示光发射机所有工作状态及参量。

            完善的激光器工作监测及?;さ缏?,使产品具有高稳定、高可靠的工作性能。
