Integrated Transceiver for Coherent Optical Backhauling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional optical communication networks face challenges in reducing latency and costs while managing multiple services due to the need for separate schedulers for each service type, leading to increased complexity and footprint in distributed architectures.
Innovation Solution
An integrated transceiver is developed that includes both coherent and non-coherent optical transceiver portions, with an integrated media access control (MAC) processor to coordinate scheduling between the two, enabling efficient data traffic management and reducing latency by sharing intelligence between components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If separate schedulers are used for each service type in distributed architectures, then multiple services can be supported, but device complexity and hardware footprint increase
Solution Approach 1:
The patent combines multiple service schedulers into a single integrated scheduler that can handle multiple service types (PON, DOCSIS, mobile x-haul) within a unified architecture. This consolidation reduces the number of separate hardware components needed while maintaining the ability to support diverse services through software-based service-specific processing.
Solution Approach 2:
The integrated scheduler is designed as a universal component that can perform scheduling functions for multiple different service types and network protocols. By making the scheduler multi-functional rather than having separate dedicated schedulers for each service, the system reduces hardware footprint while preserving service diversity.
2Adaptability or versatility
If separate schedulers are used for each service type, then multiple services can be managed independently, but latency increases due to multiple scheduling layers
Solution Approach 1:
By merging multiple service schedulers into a single integrated scheduler, the patent eliminates the need for data to pass through multiple separate scheduling layers. The unified scheduler processes all service types in a single pass, reducing the time required for packet forwarding while maintaining independent service handling through software-based processing.
3Use of energy by stationary object
If distributed architectures are implemented to relieve hub constraints, then space and power requirements at hub are reduced, but coordination complexity between hub and distributed nodes increases
Solution Approach 1:
The integrated scheduler in distributed nodes is designed as a universal component that can handle multiple service types and communication protocols. This multi-functionality reduces the need for specialized coordination mechanisms between hub and nodes, as the same integrated scheduler architecture can be deployed consistently across different network elements, simplifying overall system coordination.

AI summary
An integrated transceiver is provided for a coherent optical communication network. The integrated transceiver includes a first optical transceiver portion configured to receive and transmit coherent optical signals from and to the coherent optical communication network, respectively. The integrated transceiver further includes a second optical transceiver portion configured to receive and transmit non-coherent optical signals respectively from and to a non-coherent optical communication network. The integrated transceiver further includes an integrated media access control (MAC) processor disposed between the first and second optical transceiver portions. The integrated MAC processor is configured to (i) exchange cooperative scheduling information from the first optical transceiver portion to the second optical transceiver portion, and (ii) enable the first optical transceiver portion to schedule data traffic between the coherent and non-coherent optical communication networks using scheduling information obtained from a control plane of the second optical transceiver portion.
