Submarine Optical Cable System OXC Branching

The patent merges multiple branch fiber connections into a single trunk fiber connection by using OXC equipment at the branch station. Instead of having separate branch fibers for each member, the OXC equipment allows multiple services to be multiplexed and transmitted through a single trunk fiber, thereby reducing the number of fibers required and simplifying the system architecture while maintaining the ability to serve multiple members.

The OXC (Optical Cross-Connect) equipment provides multi-functionality by enabling a single trunk fiber connection to handle multiple services from multiple members. The OXC equipment can dynamically allocate and switch optical signals, allowing the same physical fiber infrastructure to serve multiple purposes and multiple members, thereby reducing the need for dedicated branch fibers for each member.

The patent combines multiple independent fiber pair allocations into a shared trunk fiber infrastructure. Instead of each member having dedicated fiber pairs, the OXC equipment enables multiple members to share the same trunk fiber resources through optical signal switching and multiplexing, thereby reducing the total number of fiber pairs required while maintaining bandwidth allocation flexibility.

The OXC equipment introduces dynamic resource allocation capabilities, allowing bandwidth to be flexibly assigned and reconfigured based on actual service requirements. This dynamic switching capability enables the system to adapt bandwidth allocation in real-time without requiring dedicated physical fiber infrastructure for each member, thus optimizing fiber utilization.
