Optical Transceiver Fiber Patch Panel Curved Guiding Surfaces
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing optical transceivers with output ports arranged in two lines side by side lead to optical fiber overlap and overbending, which is undesirable.
Innovation Solution
Incorporating a fiber patch panel with curved or inclined guiding surfaces in the optical transceiver to manage the bending of optical fibers, ensuring a minimum radius of curvature of 5 mm or greater, and unequal numbers of first and second fiber patch slots to accommodate multiple fibers while preventing overbending.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If output ports are arranged in two lines side by side to reduce device size, then device size is reduced, but optical fibers become overlapped and overbent
Solution Approach 1:
A fiber patch panel is introduced as an intermediary component between the input assembly and output port. This panel provides dedicated routing paths and guiding surfaces that mediate the connection between optical fibers and ports, preventing direct overlap and overbending while enabling compact port arrangement.
Solution Approach 2:
The fiber patch panel utilizes three-dimensional space by creating vertical and lateral routing dimensions. Optical fibers are guided through multiple levels and angles rather than confined to a single plane, allowing compact port arrangement without fiber overlap through spatial separation in multiple dimensions.
2Device complexity
If optical fibers are routed directly between ports without guiding surfaces, then device complexity is reduced, but optical fibers cannot be properly guided and may overbend
Solution Approach 1:
Curved guiding surfaces are provided within the fiber patch panel to guide optical fibers along controlled curved paths. These surfaces ensure fibers bend within acceptable radius limits, preventing damage while maintaining reliable optical transmission through properly shaped routing paths.
3Ease of manufacture
If equal numbers of fiber patch slots are provided, then manufacturing is simplified, but multiple fibers cannot be properly accommodated without overbending
Solution Approach 1:
The fiber patch panel employs an asymmetric slot configuration where the number of first fiber patch slots differs from the number of second fiber patch slots. This asymmetry enables flexible accommodation of varying fiber quantities and routing requirements, allowing multiple fibers to be properly managed without overbending while maintaining manufacturing feasibility.

AI summary
An optical transceiver includes an input assembly, an output port, a fiber patch panel, multiple first optical fibers and multiple second optical fibers. The input assembly is arranged on a circuit board and has a first input port and a second input port. The fiber patch panel is arranged between the input assembly and the output port, and has multiple first fiber patch slots and multiple second fiber patch slots. The first optical fibers are connected to the first input port and the output port. The first optical fiber passes through the first fiber patch slot and the second fiber patch slot. The second optical fibers are connected to the second input port and the output port. The second optical fiber passes through the first fiber patch slot and the second fiber patch slot. The second fiber patch slot accommodates the first optical fiber and the second optical fiber.
