Solution Overview
Problem
Data centers face challenges in achieving ultra-high density cabling with low loss budgets while ensuring rapid installation of fiber optic connectors that do not damage the connectors and minimize signal loss.
Innovation Solution
An optical connection system comprising an adapter and connector with a delatch actuator, latch elements, and a cable gland assembly that securely mates with an optical receptacle, allowing for easy connection and disconnection while maintaining signal integrity and protecting against ingress.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If fiber optic connectors are installed rapidly, then installation time is reduced, but connector damage and signal loss may increase
Solution Approach 1:
The connector housing includes pre-configured latch elements and alignment features that automatically engage when the connector is inserted into the adapter. The latch hooks are pre-positioned to snap into locking channels, and the alignment pins are pre-aligned with their corresponding holes, enabling rapid one-handed connection without manual adjustment or complex alignment procedures.
Solution Approach 2:
The connector and adapter are designed with self-latching mechanisms where the latch hooks automatically engage with the locking channels upon insertion. The alignment pins automatically guide the connector into proper alignment, and the O-ring seal automatically positions itself to prevent ingress, eliminating the need for manual operations during installation.
2Productivity
If connector density is increased, then bandwidth capacity is improved, but installation complexity and potential for damage increase
Solution Approach 1:
The system divides the cabling infrastructure into modular components: connectors, adapters, cable assemblies, and receptacles. Each adapter can independently house multiple connectors, allowing the system to scale bandwidth capacity by adding more adapters rather than increasing the complexity of individual connection points. The latch mechanism is segmented into independent latch hooks for each connector position.
Solution Approach 2:
The adapter design provides universal functionality by accommodating multiple different connector types through standardized adapter interfaces. The same adapter housing and latch mechanism structure can support various connector configurations, allowing data centers to achieve high density without increasing installation complexity for different connector types.
3Ease of operation
If connector installation is simplified, then installation time is reduced, but protection against ingress and environmental factors may be compromised
Solution Approach 1:
The connector housing integrates multiple protective functions into a single structural component: the housing itself provides mechanical protection, the O-ring seal integrated into the housing provides ingress protection, and the latch mechanism integrated into the housing provides secure retention. This merged design eliminates the need for separate protective elements that would complicate installation.
Solution Approach 2:
The O-ring seal is pre-installed and pre-positioned within the connector housing, automatically providing ingress protection upon connection without requiring separate installation steps. The latch mechanism automatically engages to secure the connector, and the alignment pins automatically guide proper positioning, all while maintaining environmental protection through the integrated seal design.

AI summary
An optical connection system for use with a receptacle and an optical cable assembly includes an adapter and connector. The adapter has an adapter latch element, and the connector has a connector latch element. A delatch actuator with a delatch arm is disposed on the connector housing for movement from a locking position to an unlocking position. One of the adapter latch element and connector latch element is a bendable latch hook and the other is a locking channel. When the connector housing is mated with the adapter, the delatch arm allows the bendable latch hook to latch with the locking channel in the locking position and unlatches the bendable latch hook from the locking channel as it moves to the unlocking position. An actuator lock movably supports a blocking member on the connector for selectively blocking the delatch actuator from moving to the unlocking position.
