Main application products

Repeater

Repeater (RPT 1660) is the core equipment of repeatered system, which adopts erbium-doped fiber amplification technology to compensate the transmission loss, prolong the transmission distance and enlarge system capacity.

Branching Unit

Branch Unit (BU 1650) is a submersible equipment to distribute communication service to different stations. It establishes interconnections between multiple sites within a submarine network system, reduces the complexity of networks, and significantly improves the flexibility of the network system.

Power Feeding Equipment

Power Feeding Equipment (PFE 1670) is a high-precision constant current power supply device and is used in repeatered submarine cable systems. The maximum output voltage could achieve 18 kV. PFE 1670 ensures long-term stable operation of submerged equipment. The embedded electroding signals support marine cable fault localization.

Open Cable Access Equipment

Open Cable Access Equipment (OCAE) monitor the performance of underwater equipment. It integrates with the network management system to provide real-time network performance information.
