Branching Unit - BU 1650
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.
Flexible Network Control, Suitable for Multiple Scenarios
High Fiber Count
Up to 32 fiber pairs for different network applications, meet the needs of Large-capacity transmission.
Flexible Configuration
Support traffic allocation at different levels (Fiber/Spectrum) to enhance networking flexibility.
Fault Isolation
Support flexible optical switch and high voltage hot switch to increase traffic resilience.
High Reliability
Utilize pressure-resistant and anti-corrosion titanium alloy housing and high-sealing structural design, and high-reliability redundancy backup design to ensure stable operation at 8,000m water depth for 25 years.
Reconfigurable Optical Add/Drop Multiplexer - ROADM 1680
The Reconfigurable Optical Add/Drop Multiplexer (ROADM 1680) works with the Branching Unit (BU 1650) to implement wavelength-level reconfigurable capability on the specific fiber pairs (FPs). Based on the Wavelength-Selective Switch (WSS) technology, an add/drop ratio ranging from 0% to 100% can be achieved, providing flexibility for network bandwidth.
Dynamic Traffic Reallocation
High Fiber Count
Support 4 fiber pairs ROADM function on cable trunk, maximum 16 fiber pairs ROADM function (cascaded).
Flexible Reallocation
Support wavelength add/drop multiplexing at any ratio of Add/Drop without guard band, matching customer’s dynamic service requirement.
Intelligent Management
Support real-time operating status query and key parameters configuration via the network management system.
High Reliability
Utilize pressure-resistant and anti-corrosion titanium alloy housing and high-sealing structural design, and high-reliability redundancy backup design to ensure stable operation at 8,000m water depth for 25 years.
