Optical Termination Box Layout With Exposed Rear Adapter
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing optical termination boxes require additional space for storing optical cords due to the adapter being housed inside the tray, leading to increased dimensions.
Innovation Solution
The optical termination box design includes a module case with a front adapter and a rear adapter holder fixed to the housing, allowing optical cords to be connected externally, eliminating the need for internal storage space by sliding the module case forward while keeping the rear adapter exposed.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the adapter is provided inside the tray, then optical cords can be connected, but the dimensions of the optical termination box increase due to space required for storing optical cords
Solution Approach 1:
The adapter assembly is segmented into a tray portion and a housing portion that can be separated. The housing portion with the adapter remains in the housing, while the tray portion can be pulled out independently, allowing optical cord connection without requiring the entire box to be enlarged for cord storage.
Solution Approach 2:
The tray is extracted as a separate movable component from the housing. By pulling the tray out of the housing, optical cords can be connected to the adapter without needing internal storage space within the housing, thus reducing the overall box dimensions while maintaining connection functionality.
2Device complexity
If the adapter is fixed inside the housing, then the structure is simple, but optical cords cannot be easily inserted or removed
Solution Approach 1:
The adapter assembly is divided into a stationary housing portion that remains simple to manufacture, and a movable tray portion that provides ease of operation. The housing portion contains the adapter in a fixed position for structural simplicity, while the tray portion can be pulled out to enable easy optical cord connection and disconnection.

AI summary
An optical termination box includes a housing, a module case slidably attached in a front-rear direction with respect to the housing, a front adapter fixed to a front end of the module case, an adapter holder disposed on a rear end side of the module case, a rear adapter fixed to the adapter holder, and an optical fiber that connects the front adapter to the rear adapter. The adapter holder is fixed to a rear end portion of the housing such that the rear adapter is exposed rearward of the housing.
