UCLL Sub Loop Co-Location

Economic Life of a Cabinet


Ucll sub loop co location

Overview

  • Physical life of FTTN cabinets is 20 years.

  • Economic life depends on:

    • When FTTN is over taken

    • Whether cabinets are made redundant at that point.

  • Our best estimate of economic life is 10 years

When will FTTN be overtaken?

  • Technology is rapidly evolving.

  • 10 years ago:

    • Telecom was installing dialup internet capability

    • An initial ADSL trial was being run, and the first ADSL commercial deployment design was just beginning. ADSL services were commercially available beginning in 1999.

  • Today

    • We are in our 4th generation of ADSL technology

    • Installing cabinets to improve customer line rates

    • VDSL2 is beginning to be deployed

    • Mobile technology is delivering Broadband, ever increasing

    • Govt policy is to deliver FTTH to 75% of NZ in the next 5 years

    • Mobile Technology delivers Broadband, 3G will make this faster

Placing VDSL2

  • Orcon/Kordia/Callplus has argued that the move to VDSL2 will extend the economic life of the cabinet to 20 years (2028)

  • VDSL2 from the cabinet will only deliver 20 Mbps. This is unlikely to satisfy customers for more than 10 years (on average).

  • To deliver the benefits of VDSL2 – 70 Mbps (on average)- we need to get VDSL2 technology to within 300m copper line of each house.

  • This is FTTC, which will not use FTTN cabinets.

When will FTTN be overtaken?

  • It is clear that it will be less than 20 years (2028).

  • In 10 years, customers will not be satisfied with 20Mbps

  • In places, FTTC or FTTH will be here in 5 years

  • Chorus estimates an average cabinet life of 10 years (2018)

Cabinets will be redundant when FTTN is overtaken

  • Post-FTTN cabinets need to be in a different place.

  • Post-FTTN cabinets will be a different size.

  • Post-FTTN cabinets will not need power.

  • When making the transition from FTTN to FTTH, the old cabinets need to stay working while the new cabinets are installed.

FTTH cabinets will be in a different place

  • FTTN cabinets need to be situated close to the customers premise, to shorten the copper lengths.

  • FTTN cabinets are placed to serve a maximum of 330 working lines, this allows for infill growth.

  • FTTH cabinets don’t need be close to the customers premise.

  • FTTH cabinets can serve 512 working customer lines.

  • FTTH cabinets will be located further away from the customer and will aggregate more customers.

  • FTTN and FTTH cabinets are located in different geographical positions for different reasons.

  • It is uneconomic to locate FTTH cabinets where we locate FTTN cabinets.

Re-using FTTN Cabinets is unrealistic.

  • A FTTN cabinet is power fed.

  • A FTTN cabinet fills the maximum allowable space under RMA rules for cabinets.

  • A FTTH “PON” cabinet is a lot smaller and requires no power.

  • It is overbuild - to remove and refurbish a large FTTN cabinet in order to relocate it to house the small FTTH “PON” equipment.

  • We could not fit the “PON” equipment in the FTTN cabinet.

  • FTTN and FTTH cabinets would need to be simultaneously working in order to migrate customers over without disruption.
