Abstract
Nowadays a Fibre to the Home (FTTH) network plays a
crucial role in developing the information society. The
increasing popularity of FTTH deployments observed
over the last few years has resulted in millions of
homes already passed, but in comparison the homes
connected market penetration is still relatively small
(2.9% of households in US, less than 4% in Europe, and
approximately 25% in Asia
[1]
).
The next growth opportunity in FTTH that enables
acceleration of market penetration is coming from Multi-
Dwelling Units (MDU) deployments. In typical MDUs the
fibre is brought to the floor level and shared by several
dwelling units. Network deployments in challenging MDU
environments are different than in any single-family house
and require an adequate technology. Additionally, as
deployments increase, customers will have trouble finding
enough skilled splicing technicians to realise large roll
outs.
To meet today’s market demand Corning designed a FTTH
MDU solution (ASCEND™) which uses an advanced riser
cable assembly named OptiRise™. Riser Cable Assembly
solves major deployment issues and enables MDU
installations to be faster, easier and more reliable.
The fibre optic cable consists of network access points
which are pre-installed at customer-specific locations
distributed along the length of the cable.
The system is manufactured and tested in the factory, then
packaged and shipped to the customer for immediate
deployment.
