2. 2
Blown Fibre Ducting
▪ Dig once
▪ Blow high fibre count, ribbonised cables
▪ Blow out the old and replace with high grade
or higher fibre count cables
▪ Blow long routes and then splice at mid-span
locations
▪ Blown-fibre tubes can be coupled together to
allow the fibre to be blown to the correct
location
▪ Pre-connectorised fibres can also be blown

3. 3
Aerial Deployment (Pole-to-Pole)
▪ Utilise existing underground cable routes to serve
an aerial deployment
▪ Feed subsequent poles aerially
o To feed each pole individually from an underground
network but link poles together by looping through
each aerial node and dropping off the fibre needed
there
▪ Deploy passive optical devices, e.g. splitters, in the
aerial node to extend the reach of light-weight fibre
cables to multiple nodes
▪ Provision of the extended aerial node off-site and
deploy in one go
OR
▪ Splice at height to reduce service loops

4. 4
Connectorised ODNs
▪ Splicing can’t be avoided but it can be
minimised
▪ Add configurability to the network
▪ De-skill the deployment of the L2C
elements
▪ Design the ODN to allow for the losses of
a small number of physical connections
▪ Place them nearer to the final point of
connection
▪ Use APC-style connectors for P2MP
ODNs

5. 5
Pre-Configured and Connectorised Solutions
▪ Utilise standardised but pre-configured network
elements to minimise misinterpretation and maximise
deployment efficiency
▪ Blow pre-connectorised (ferruled) fibres along pre-
installed ducts for most efficient L2C works
▪ Trade-offs between CapEx and OpEx and the efficiencies
of building core Vs last-mile ODN segments should be
well understood by the business
o Maximising fibre core counts will allow for network
reconfiguration for future generations and technologies
o Centralised or decentralised passive optical devices and
Cex capabilities to ensure optimum future proofing

6. 6
Dealing with Multi-Dwelling Units (MDU’s)
▪ Fibre from the dwelling to the building entry point once
▪ Allow multiple operators to utilise the fixed fibre infrastructure
▪ Utilise blown-fibre ducts to allow for easy L2C
▪ Consider a distributed model with short L2C connections that eliminate
reworking of fibre breaks and barriers
▪ Pre-connectorisation can increase deployment efficiency

7. 7
The Scale of the Small MDU
▪ 1-8 dwellings
▪ Home-run individual dwellings with some
opportunities for pre-connectorisation
▪ Easily fed from access network via existing
infrastructure, e.g. street-side cabinets
▪ Passive optical components, if required can be either
in the OSP or building distributor
▪ External building facade can be used to minimise
building access

8. 8
The Scale Of The Medium MDU
▪ Up to 24 dwellings
▪ Options for decentralised administration to fit
deployment model and technology
▪ Riser or external facade installation
▪ Mix P2P and P2MP options to ensure maximum
future potential

9. 9
The Scale Of The Large MDU
▪ Multiple floors and dwellings per floor
▪ Decentralised administration and
connectivity to optimise LTC in brownfield
deployments, including hallway distribution

10. 10
Serving the MDU
▪ Not all MDU’s require a dedicated cable from the POP
▪ Many small to medium MDU’s are mixed in with multiple SDU’s to create a
more diverse residential living experience
▪ MDU’s can be fed from local street-side cabinets, housing the passive optical
elements.
▪ Dedicated connections and splice trays help segregate these pathways in the
external closure
