Solution Overview

Problem

Current passive optical networks face challenges in efficiently extending fiber optic services to new areas due to the complexity and cost associated with integrating telecommunications enclosures and managing optical fibers, splitters, and power splitters within these networks.

Innovation Solution

A splitter module with a housing that includes a splitter, input, and output fibers, along with an enclosure arrangement featuring a base and cover that provides access and sealing for fiber routing and splicing, utilizing ruggedized adapters and a method for connecting feeder fibers to output fibers through splicing and sealing mechanisms.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If traditional telecommunications enclosures are used to house splitters and fiber routing components, then fiber optic services can be extended to new areas, but the complexity and cost of integrating and managing these components increases

Engineering Contradiction:
Improvefiber optic service extension capabilityVSAvoidintegration and management complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The splitter is integrated within the housing that forms part of the telecommunications enclosure structure. The input and output fibers are routed through channels within the housing itself, nesting the fiber distribution function within the structural enclosure, thereby reducing the number of separate components and simplifying integration

Inventive Principle:
Principle #7Nested doll (Nesting)

Solution Approach 2:

The patent combines the splitter, fiber routing channels, and enclosure housing into a single integrated module. The housing serves both as the structural enclosure and as the fiber routing infrastructure, merging multiple functions into one component that reduces overall system complexity

Inventive Principle:
Principle #5Merging (Combining)

2Adaptability or versatility

If traditional telecommunications enclosures are used to house splitters and fiber routing components, then fiber optic services can be extended to new areas, but the cost of integration and management increases

Engineering Contradiction:
Improvefiber optic service extension capabilityVSAvoidintegration and management cost
Core Design Contradiction:
Adaptability or versatilityVSEase of manufacture

Solution Approach 1:

By nesting the splitter and fiber routing channels within the housing structure, the patent eliminates the need for separate fiber management components and reduces the number of assembly steps, thereby lowering manufacturing and installation costs while maintaining service extension capability

Inventive Principle:
Principle #7Nested doll (Nesting)

Solution Approach 2:

The housing serves multiple functions simultaneously: it provides the structural enclosure, contains the splitter, routes the fibers, and protects the components. This multi-functionality reduces the total component count and simplifies manufacturing, lowering overall costs

Inventive Principle:
Principle #6Universality (Multi-functionality)

3Ease of operation

If fibers are routed through traditional enclosure structures, then connection locations are provided for end users, but accessibility and ease of management become difficult

Engineering Contradiction:
Improveconnection location accessibilityVSAvoidfiber routing management complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The housing includes asymmetric features such as the contoured minor axis and specifically positioned entry and exit openings that facilitate easy access from the front while maintaining secure routing internally. The input fiber enters through one end while output fibers can exit through multiple directions, creating an asymmetric but user-friendly interface

Inventive Principle:
Principle #4Asymmetry

AI summary

An optical splitter module (140) can be carried on a cover (120) of an enclosure (100) between a contoured surface (129) and a row of optical adapters (130). Output pigtails (165) from the splitter module (140) are routed to the optical adapters (130). In certain examples, a significantly longer input fiber (161) is routed from the splitter module (140) to a splice region (114) at a base (110) of the enclosure (100). Certain types of splitter modules (140) are mounted to the cover (120) at an angle relative to an insertion axis for a feeder cable (170). A certain type of splitter module (140) curves about a minor axis (A2) so that one major surface (142) has a concave curvature and another major surface (143) has a convex curvature.
