design trends
Don’t Let This Happen To You
Improper Bend Radius
No Clear Migration
Path
–
Equipment Placement - Cabinet Layout
• Switch Location
• Server Cabinet
Patch Panel
• Use of Cable
Management Panels
• Use of Vertical
Cable Managers
Example of Poor Use of Rack Space, No Migration
Planning, & Poor Cable Management.
“Any to All”
“Any to All”
Connectivity design will support
multiple equipment and
applications.
Change out equipment not
infrastructure
MDA or HDA
HDA or EDA
Advantages:
•
Allows for faster “roll outs”
•
Designed “Zones” with multiple connections
– as required by equipment design
•
Reduce the number of cable pulls
•
Managed cabling strategy – Trunk cables
•
Adapt to frequently changing connection models or media
types
• Critical Design Factors
– Talk the same Language ie.
Stands vs. Channels
– Enclosure / Cabinets
– Connector types
– Define Polarity Method
– Cable Types
– Equipment & Migration Path
– Redundancy

Copper Trunk Cables
– Cables can be
doubled ended or
single ended
– Factory Terminated
and Tested
– Connectors can be
different types
SC,LC,MTP, MU, other

Assemblies
• What Are They?
Factory terminated
modules that utilize
multifiber (MTP/MPO)
connector with breakout kit
to individual fiber
Is Plug & Play Limited to
Cassettes?
– MTP Brackets:
Reduce number of “Hops”.
Reduce System Loss.
Reduce System Cost.
Work above the Floor.
Advantages:
Advantages:
• Simplified Installation
• Reduce human errors
• Less time in the floor
– less disruption and debris
• Factory terminated and pre-tested
– minimizes points of failure
• Uniform design and consistent documentation
