Solution Overview
Problem
Current optical fiber connectors are too large for smaller optical modules and require two separate ports, making them difficult to install and service in compact spaces.
Innovation Solution
A compact optical fiber connector design that eliminates the need for two separate ports by using a removable faceplate with spring tabs to secure optical fibers, allowing for efficient coupling of two or more fibers in a single assembly, compatible with both standard LC connectors and non-standard compact connections.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a standard LC duplex connector is used to connect two optical fibers, then reliable optical connection is achieved, but the connector occupies large volume and requires two separate ports
Solution Approach 1:
The patent merges two separate LC connector ports into a single integrated connector body. The connector housing contains both a first LC connector port and a second LC connector port within one unified structure, eliminating the need for two separate connector assemblies while maintaining reliable optical connections for both fibers.
Solution Approach 2:
The single connector housing serves multiple functions by accommodating both the first and second LC connector ports, as well as housing the alignment sleeve and securing mechanisms. This multi-functional design reduces the overall number of components needed in the optical assembly.
2Reliability
If two separate connector ports are used to connect optical fibers, then proper alignment and connection are ensured, but installation and service become difficult in compact spaces
Solution Approach 1:
By combining both fiber connections into a single connector housing with integrated alignment sleeve, the patent simplifies the installation process. The alignment sleeve automatically aligns both ferrules when the connector is assembled, ensuring proper fiber alignment while reducing the complexity of manual alignment procedures in compact spaces.
3Volume of stationary object
If a compact connector design is implemented to reduce volume, then space is saved for smaller optical modules, but the connector may compromise on connection stability
Solution Approach 1:
The patent incorporates spring tabs that provide dynamic securing force. The spring tabs are biased to engage with the ferrules, providing automatic retention and secure connection. This dynamic mechanism ensures connection stability while maintaining a compact connector housing volume.
Solution Approach 2:
The alignment sleeve uses a cylindrical geometry that provides precise rotational alignment of the ferrules. The circular cross-section ensures consistent alignment regardless of assembly orientation, maintaining connection reliability in the compact connector design.

Function Achieved in This Case
The solution reduces the volume required for optical connections, enabling easier installation and service in space-constrained environments while ensuring proper light transmission between fibers.
Implementation Method 1
The one or more spring tabs may also engage with the removable faceplate, thereby holding the optical fiber plug in place so as to ensure proper light transmission from the fiber to an opposing fiber

AI summary
In some embodiments, the present disclosure is directed at an optical fiber connector that occupies a small volume, and can therefore fit into small optical modules. In some embodiments, the optical fiber connector may comprise a removable faceplate. During installation, the faceplate may be removed to allow an optical fiber plug with a flange to be placed within the optical fiber connector. The flange may comprise one or more spring tabs. The faceplate may then be re-attached to the optical fiber connector, wherein at least a portion of the faceplate engages with the flange and secures the optical fiber plug with the optical fiber connector. The one or more spring tabs may also engage with the removable faceplate, thereby holding the optical fiber plug in place so as to ensure proper light transmission from the fiber to an opposing fiber.
