Optical Transmission Device LCK Signal Path Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional optical transmission systems experience increased power consumption due to excessive transmission of LCK signals during maintenance and setting procedures, which is not limited to LCK signals and can occur with other maintenance-related signals.
Innovation Solution
An optical transmission device is designed to generate and transmit LCK signals through a single path using a first frame generator and a second frame generator, where the LCK signal is accommodated in a third frame with a bandwidth equal to or smaller than the second frame, reducing the number of active transmission circuits and thus minimizing power consumption.

Engineering Contradiction Analysis
1Ease of operation
If LCK signals are transmitted through all transmission circuits during maintenance and setting procedures, then the maintenance and setting operations can be performed effectively, but the power consumption of the communication device increases
Solution Approach 1:
The patent segments the transmission of LCK signals by identifying and activating only the specific transmission circuit (first transmission circuit) that corresponds to the affected path, while keeping other transmission circuits inactive. This segmentation allows maintenance operations to be performed on specific paths without unnecessarily activating all transmission circuits, thereby reducing power consumption while maintaining operational effectiveness.
2Reliability
If all transmission circuits are activated to transmit LCK signals, then comprehensive path coverage is achieved, but unnecessary power consumption occurs
Solution Approach 1:
The patent applies local quality by making different transmission circuits have different operational states based on their specific function. The first transmission circuit is activated to transmit LCK signals for the affected path, while other transmission circuits remain inactive. This localized activation ensures reliable path coverage for maintenance operations without the energy waste of activating all circuits uniformly.
3Reliability
If the LCK signal is transmitted through multiple paths, then redundant coverage is provided, but the power consumption increases
Solution Approach 1:
The patent applies partial action by transmitting LCK signals only through the necessary first transmission circuit rather than through all available transmission circuits. This partial activation provides sufficient reliability for maintenance operations on the affected path without the excessive power consumption that would result from activating all transmission circuits.

AI summary
Optical transmission device includes: first frame generator, second frame generator and transmission circuits. The first frame generator generates first frame. The second frame generator generates one or a plurality of second frames from the first frame. The number of the second frames corresponds to bandwidth of the first frame. The transmission circuits transmit the second frames. When specified bit pattern is transmitted to second optical transmission device, (1) the first frame generator generates third frame including the specified bit pattern, bandwidth of the third frame being equal to or smaller than bandwidth of the second frame, (2) the second frame generator generates fourth frame having the same format as a format of the second frame, the third frame being accommodated in the fourth frame, and (3) the fourth frame is transmitted to the second optical transmission device by selected one of the transmission circuits.
