The document discusses strategies for faster fibre deployment, including blown fibre ducting to lay high fibre count cables, aerial deployment from poles, using connectorised optical distribution networks to minimize splicing, and pre-configured connectorised solutions. It also covers approaches for multi-dwelling units of different scales, such as blowing fibre ducts, home-run connections, and decentralized administration models depending on the size of the MDU. MDUs can be served from local street cabinets rather than dedicated cables from central offices.

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
