Product Classic Networking Application The optical splitting and amplification equipment is widely used in scenarios such as network traffic monitoring and big data analysis for frontend optical splitting and amplification. This equipment is connected in series with the service line, efficiently replicating the business data on the line and sending it to the monitoring equipment. It is completely transparent to the service, does not affect the original line's service transmission, and the line can operate normally even if the equipment loses power. It supports rates ranging from 100Mbps to 10Gbps.
