Chapter 1- Intorduction to Outside Plant (OSP) Flashcards
The Majority of OSP facilities are, installed, and maintained by Local Access Providers (APs) - True - False
TRUE
OSP may Include
Optical Fiber Cabling
Balanced Twisted Pair Cabling
Coaxial Cabling
Supporting structures are required to link serving outlying areas to enable
Voice, Data, Video, and other low voltage systems
OSP designers are responsible for Inter building and EF designs and should have knowledge of them. An OSP designer should have knowledge of -
Pathway and Spaces
Cabling
Bonding and Grounding
Right-Of-Way (R/W)
System Documentation
Applicable Codes and Standards
To stay current an OSP Professional should stay current and take advantage of -
Industry Related Organizations
Internet
Continuing Education
Meetings and Conferences
Government Regulations
OSP Networks may differ because of -
Topography
Climate
Choice of Cabling
Economics
Local Code Requirements
Network Functionality
Current and future types of support equipment
Client Requirements
Building Codes and Standards regulate construction. Their purpose is to -
Protect -
Life
Health
Property
Local Codes regulated by the Authority Having Jurisdiction (AHJ) -
Cover Installation methods, Materials, and Electrical Products
STANDARDS are intended to ensure system performance by providing requirements and guidelines -
In general, Standards are established as a basis to compare, measure, or judge -
Capacity
Quantity
Content
Extent
Value
Quality
The methodology is the implementation of practices and procedures within the industry.
Design manuals are examples of -
METHODOLOGY
Standardization may DIFFER because of -
- Topography
- Climate
- Choice of cabling
- Economics
- Local code requirements
- Network functionality
- Current and Future types of equipment
- Client Requirements
Standards are BENEFICIAL because -
- Promote design and installation Consistency
- Impose conformance
- Provide a structured telecommunications facility
- Provides uniform documentation
Planning the construction of an OSP network may require -
Completing a needs assessment
Determining the capacity of an existing network
Calculating transmission requirements
Coordination with AP’s, AHJs, and utilities
Ensuring compliance with safety regulations and practices
Determining the need for R/W
Selecting the physical topology
selecting a route
selecting desired cable type
Preparing to send a request for Information and evaluating the responses
Right - Of - Way
If the network is going to extend beyond the property owned by the client -
Leased lines for the AP may be obtainable
A Franchise agreement may be purchased
Need to obtain R/W arises
A boundary outside the clients property is a Right - Of - Way, the client must buy a strip of land or obtain written permission -
To attach to a utility pole
Use utility conduit
Use public Right of way or AP or Utility easements
From Private parties using their land
3 types of OSP Pathway and Spaces
- Underground
- Direct buried
- Aerial
Types of UNDERGROUND Pathway
- Conduit
- Maintenance Holes
- Hand Holes
- Utility Tunnels
- Vaults
Types of Direct Bury pathway
- Trenches
- Pedestals and Cabinets
Types of AERIAL pathway and space
- Poles
- Support Strand / Messenger
- Anchors
- Guys
OSP Standardization
Design and installation consistency
Impose conformance to requirements
provide a structured Telecommunications Facility
Enable efficient system expansion and other changes
Provide for unifirom documentation
Codes - Standards - Methodology
Codes address safety
Standards are requirements and guidelines
Methodology is practices within an industry
Project Documentation
Plan view showing obstacles and utilities
Notification of known hazards
Measurement for facility placement
ROW limits
Support Structures
Media
Protection Plans
OSP outside the customers land
Need to buy the land, or get written permission
