BU 1650 products enable fibre pairs to be split off to multiple destinations in a submarine network system.
Branching Unit - BU 1650 Product Series
Enable the flexible submarine networks both on optical domain and electronical domain
These products support fibre add-and-drop connectivity and Optical Add-Drop Multiplexing (OADM) in the optical domain, and support passive connectivity and power switching functions in the electrical domain.
Optical Routing
The BU 1650 flexibly provides the full fibre pair routing function and optical add and drop multiplexing (OADM) function to meet the specific requirements of the system.
Power Switch
The power configuration status of the BU 1650 can be changed, providing more flexibility to system power configurations.
High Reliability
The BU 1650 adopts both well-proven components and an appropriate redundant design for high reliability. The BU 1650 is manufactured under a severe process control. Within these guidelines, the BU 1650 can provide high quality performance throughout a design life of 25 years.
Mechanical Design
BU 1650 has a small body and a light weight due to its unique compact structure, allowing easy transport and installation. The BU 1650, with sea case and perfect sealing, is capable of withstanding pressure at water depths of up to 8000 m. The BU 1650 adopts Universal Joint (UJ) technology and can be connected to all types of UJ-certified submarine cables.
