Three-Layer Open Model (3LOM) – The VX Fiber Model
VX Fiber believes in dismantling this model by opening-up
the network and separating the network infrastructure and
management of the network from the supply of services.
The VX Fiber Model, is a three-layer Active Open Access
model, which consists of the separation of the physical
infrastructure, operations and service provisioning i.e.
the roles of the Fibre Owner, Fibre Operator and SP are
explicitly separated. Here, competing SPs share a common
FTTP infrastructure run by a neutral wholesale operator.
The network is open to all providers on the same terms and
conditions, providing a real choice for subscribers.
In this case, a Local Authority has the same role as in
the PLOM. But at the active layer, the Fibre Operator role
is assigned by procurement to one company. The Fibre
Operator places active equipment in all access nodes and
builds an open, operator-neutral network over which all
SPs can deliver their services to all subscribers.
In order to guarantee fair and non-discriminatory
conditions to all SPs (promoting and maintaining operator
neutrality), the Fibre Operator is typically barred from
delivering its own services.
The backbone Fibre Owner receives revenue from the
Fibre Operator for dark fibre lease. To reach subscribers,
the Fibre Operator also leases passive connections
(fibre, copper or simply wireless frequency bands) from
the access area Fibre Owner to deliver services. Again,
subscribers can choose the services they want from their
operator of choice and pay a service fee. The service fee
from subscribers to the Service Provider generally includes
a network fee as part of the package, which is then passed
to the Fibre Operator.
In a variation of this three-layer open model, the network
fee is paid directly to the Fibre Operator. The access-area
Fibre Owner may receive revenue from subscribers in the
form of a (one-off) connection fee to the Fibre Owner and/or
a monthly network fee.
