OSP Optical Design
What is OSP Optical Design?
Outside Plant Engineering (OSP) Optical Design is the practice of engineering fiber optic-based pathways to meet Telcordia specifications related to Loop Length, Attenuation levels at 1310nm, 1550nm, 1625nm, Optical Reflection and other character- based optical requirements for optical-based telecommunications services.
Optical Fiber Characteristics:
Single mode versus multimode and the use-case of each
Optical fiber sheath make-up and considerations explained
Sheath / Buffer tube / strands (900-micron, 62.5 - micron)
Splice Configurations:
Splice Matrix versus cable counts (Telcordia)
Configuring splicing for construction drawing development
Creation of splice drawings and the Telcordia based symbology used and why
Cable placement:
Understanding environmental factors and developing accordingly
Route selection based rodent control
Storm loading (practice as part of OSP Physical Design)
Climate determinations
Other
Assessing and recommending critical requirements of master record keeping:
Optical Fiber Assignment systems based on canned software-based Customer Records Management (CRM) versus customized database development such as FileMaker (Apple Product)
Understanding budgetary requirements and constraints for the development of fiber management systems
Development of Route Design Schematics (RDS) and how this relates to construction drawings and as-built processing
Detailed Distribution Area Planning (DDap) for future growth and capacity planning:
Analysis to gain understanding of distribution area customer / subscriber bases to include service types, i.e. XPon, Ethernet, Dark Fiber
Creating distribution areas that ultimately become splice and cable configurations for both long- and short-term cable assignment growth.
Capacity Planning methodology:
How to assess regional trunk routes
Cable relief strategies
Budgetary cost analysis and projections
Optical Design Processes:
Understanding customer bases to effectively design, engineer and construct to support:Gigabit Passive Optical Design principles:
Single split
Distributed split
