Optical Transceiver Module Layout for Fiber Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional optical transceivers face challenges in efficiently arranging optical and electronic components due to limited width, leading to potential damage from optical fibers and bonding wires, which restricts the design flexibility and maintenance of communication facilities.
Innovation Solution
The optical transceiver design includes a substrate with first and second transceiver modules arranged along a direction, with optical fibers supported above the modules using V-grooves, optical fiber arrays, and covering structures to prevent contact and optimize component placement, allowing for longer transceiver utilization without width limitations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If optical fibers are routed through the substrate to connect transceiver modules, then electrical connectivity is achieved, but the optical fibers may contact and damage the transceiver modules due to limited width for arrangement
Solution Approach 1:
The patent utilizes the width dimension of the substrate to route optical fibers above the transceiver modules rather than through them. This dimensional change in fiber routing allows the fibers to connect multiple modules without penetrating or contacting the modules themselves, thereby preventing damage while achieving connectivity across the limited substrate area
Solution Approach 2:
The substrate is divided into distinct regions: a first width for routing optical fibers and a second width for arranging transceiver modules. This segmentation allows independent optimization of each region, enabling safe fiber routing paths that do not intersect with module locations while maintaining efficient space utilization
2Productivity
If transceiver modules are arranged densely to increase channel capacity, then productivity is improved, but the risk of optical fiber damage to modules increases
Solution Approach 1:
By routing optical fibers in the width dimension above the modules rather than through them, the patent enables denser module arrangement without increasing fiber-module contact risk. The fibers traverse the substrate width at a safe elevation, allowing modules to be packed more closely while maintaining fiber safety
Solution Approach 2:
The substrate acts as an intermediary structure that provides dedicated routing paths for optical fibers above the transceiver modules. This intermediate fiber routing layer allows dense module placement while preventing direct fiber-module contact, thus enabling high channel capacity without compromising reliability

AI summary
An optical transceiver includes a substrate, a first transceiver module, a second transceiver module and an optical fiber module. The substrate defines an optical transceiver end. The first transceiver module and the second transceiver module are disposed on an outer surface of the substrate, and the first transceiver module is located between the optical transceiver end and the second transceiver module. The optical fiber module includes a first optical fiber and a second optical fiber. The first optical fiber is coupled to the first transceiver module, and the second optical fiber is coupled to the second transceiver module. A part of the second optical fiber is located above the first transceiver module.
