PROPOSED EXPANSION

Comcentric is proposing to close the final gap across the region with a partially served last mile plan. This plan entails using the above described network to connect those in the more sparsely populated areas of the county.

To do this we employ three different fibre technologies, active Ethernet, GPON and NGPON2 depending on what is already in place and demand from anyone area.

Once last mile connections are completed, customers will be connected via fibre to access nodes which then are connected via 10 gig access links to the network core. The core peers with several different transport providers in London, Stratford, St Mary’s and Dublin Ontario each of which support multiple 10 gig (currently) paths to 151 Front Street.

New components to be funded under this proposal for last mile include:

1) Fibre Distribution Hubs (FDHs). Enclosures where large bundles of distribution fibre are separated into smaller, neighborhood-sized bundles of access fibre. FDHs are typically placed next to roads and along rights-of-way.
2) Fibre-to-the-Home. Access fibre runs through neighborhoods where it's either buried underground . When a resident requests service, fibre is pulled from the access fibre bundle to the Network Interface Unit (NIU) on the outside of the house. After that, installers bring cables directly into the home or business, connecting them to the Co-ops' fibre.
The proposed network will easily scale. The FTTH network being proposed is well positioned to serve customers well into the foreseeable future and is the most current FTTH technology to date.

The last mile PON network is architecturally laid out in clusters of anywhere from 20 to 32 homes per connection. Initially each cluster will be served by a GPON laser that will allow for 2.488 Gbps down and 1.244 Gbps up. In future when anyone cluster hits a sustained network utilization of 80% or above. NG-PON2 will be deployed as a non-service interrupting overlay using industry standard wave division multiplexing (WDM) technology. NG-PON2 is capable of delivering 40 Gbps to the cluster and up to 10 Gbps symmetrical service to an end point.

On the network side, the Co-ops’ current deployment of a Dense (WDM) will allow this network to scale in the foreseeable future.

Standardizing of a pure fibre deployment negates the concern for future scalability as technological developments generally outpace consumer demand.

The service delivered is an IP data connection over fibre, any service provider will be physically capable of subscribing to bandwidth from a co-located POP site to the customer in order to deliver IP services of every description. Through the use of industry standard components based on the common industry Ethernet standards IP V4 and IP V6 protocols, access to the network can be easily accommodated for third parties. Third party services that can be offered on the network include Transparent Local Area Network Services (TLS) to allow traffic to be routed from customers within our serving area to areas outside of our serving area through interconnection points with our network or potentially other Network to Network Interfaces (NNI) elsewhere.
