UCLL Sub Loop Co-Location Economic Life of a Cabinet
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
The next technologies are already here. Product Description Technology Average Copper Distance End user Speed What’s happening?

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.
