Definition
In telecommunications, Outside Plant (OSP) refers to all of the physical cabling and supporting infrastructure, such as conduits, cabinets, or poles, and any associated hardware, such as joints.
The network is bound on one side by the Point of Presence (PoP) and on the other side by either
• a further PoP (� backbone ) or• a subscriber connection (� access network )

Typical (*) Cost Breakdown of FTTH P rojectsby Network Sections
The largest cost item by far is the distribution area. Cost optimisation should be considered here.
The joint usage of existing metro /

Cost of the PoP has hardly any effect on over all costs. Therefore, high quality solutions should be given priority.
backbone network for the feeder area brings little in the way of savings.

Demand for Innovative Materialsin Optical Access Networks
• Requirements for optical subscriber access networks differ significantly from those of classical high-availability wide area networks:
– Minimal space requirements for equipment in PoPs and buildings– Very high installation and connection rates in a short time period– High price pressure
• Industry responded to these demands with a number of innovative new developments:
– Cost effective products for the residential market � cost reduction– Installation with minimally trained/retrained personnel � pre-assembly– Product optimisation for rapid installation � faster roll-out
• Effective use of these products requires changes to the mind sets of network operators and contractors
Examples of Innovative Materials
– ODFs with over 2,800 fibre connections in a single rack
– Complete mechanical sleeves without shrink seals
– Sleeves with ports for more that 50 cables
– Pre-assembled cabinets with optical splitters
Image source: NSN archive, vendors
– Pre-connectorized cables with robust outdoor connectors
– Field-mountable connectors
– Glass fibres with very low bending radius
Some of these materials are not even 5 years on the ma rket!

Cost Reduction by Using Innovative Materials
Example:
• Multi Dwelling Unit (MDU) with 120 flats• 20 floors with 6 DU/floor
Window
Field-mountable
connectors
Large box with uncutloose tubes
Splice cassette with pig tails
Standard F.O. solutionFTTH solution
• 20 floors with 6 DU/floor(Riser cable with 20 loose tubes @ 6 fibres)
Total cost (materials + services):
• Standard F.O. solution: 100%• FTTH optimized solution: 83%
Summary
Professional network planning and project managemen t are key
The cost of the OSP build represents a significant percentage of the total costs of an FTTH project.Here manpower cost is the dominant part.
Professional network planning and project managemen t are key criteria for project success.
The use of dedicated materials and state-of-the-art installation techniques contribute significantly to the rapid an d high-quality implementation of the network build.
