Olivier JERPHAGNON - (Calient)

Yesterday I met with Olivier JERPHAGNON who works for Calient Networks. Dirk VAN DER WOUDE suggested we meet because of the connection between unbundling/regulatory policy and the optical switching equipment Calient produces. The gist of our discussion was about how different topologies and technologies affect the way alternative operators can access end-users. Luckily, I was also able to talk to him for a minute about this project as well.

Here are a some of the key/interesting items he brought up:


  1. One of the competitive operators here in France is planning to have 60 POPs for all of Paris at 10,000 subscribers each. That certainly helps in terms of scale economies.
  2. Access networks are similar to airports and harbors. If cities can promote the development of airports and harbors then they should be able to put in networks as well.
  3. The more "pure" the model for structural separation, the more tax money will be needed to fund the rollout of the network.
  4. VDSL and PON FTTH networks typically have a few hundred subscribers in a street cabinet compared to our 50.
  5. Calient's equipment is useful for creating dynamic PON and end-run networks from a central point. Their equipment is usually located in a central office (exchange) but they are working on a smaller version for street-size cabinet use.

  1. Our project is small enough that it may be difficult to attract operators to come and provide services. He suggested that operators may only consider if they can be the sole provider.
  2. He emphasized that the key to attracting an operator will be having everything in place for them to connect in.
  3. One area where we may have an advantage is connecting the last 10 meters. The last few meters to reach a house and install the connection are among the most difficult and expensive for operators. We will be much more attractive to operators if, with the support of the residents, we install the network ourselves (and this last 10 meters) ourselves.
  4. He urged me to approach as many operators as possible about coming in and connecting into the network.
