New flexible remote node unifies carriers' access and backhaul
networks, delivering higher bandwidth to more customers with fewer
active sites and lower power consumption
Norcross, Georgia, USA and Martinsried/Munich, Germany.
September 29, 2008. ADVA Optical Networking today announced the
introduction of its Flexible Remote Node (FRN), an extension of the
ADVA FSP 3000 that enables network operators to cost-effectively
introduce WDM-PON (Wavelength Division Multiplexing Passive Optical
Networks) into their network. The FRN is a key element of
future-proof FTTx (Fiber-to-the-x) concepts, allowing carriers to
deliver larger amounts of bandwidth at a significantly lower cost.
In today's times of fierce price competition, higher upstream demands
and regulatory pressure for local loop unbundling, carriers are
challenged to consolidate their metro networks and rethink their
access strategies. To ensure long-term profitable service delivery,
communications providers must drive toward a strategy of converged
access and backhaul for residential and business services, fewer
active components in the access network, the elimination of local
exchanges, reduced power consumption and space utilization.
"There is true benefit to having WDM in both the access and backhaul
segments of the network," stated Christoph Glingener, chief
technology officer of ADVA Optical Networking. "There have been
several false starts in the industry regarding FTTx (Fiber-to-the-x)
deployments; many solutions have shown limited scalability,
introduced network complexity and increased operational costs. Our
new unified approach, employing a WDM-PON solution, will enable
service providers of all kinds to extend the benefits of WDM into the
access network, thereby eliminating active sites and reducing overall
network costs."
Fully integrated into the successful ADVA FSP 3000 platform, the FRN
is part of a scalable Optical+Ethernet transport solution that
enables communications providers to serve their residential, business
and wholesale customers from a unified access and backhaul network.
When located at the curb, the FRN can be configured as a purely
passive network element with environmentally hardened WDM filters
that allow the setup of a point-to-multipoint WDM-PON structure. When
located at a street cabinet, the FRN can include active equipment
such as optical amplifiers and active Ethernet technology that enable
reach extension and traffic aggregation.
The introduction of WDM into the FTTx environment is a
forward-looking and innovative concept that challenges current EPON
(Ethernet PON) and GPON (Gigabit PON) concepts. EPON and GPON
solutions use protocol-based traffic separation, which creates
security concerns for high-end users. Bandwidth scalability is
limited and affected by the demands of neighboring customers.
Loss-intensive splitting and the absence of optical amplification
limit the reach of such solutions to roughly 20km.
In contrast, a WDM-PON approach uses wavelength-based traffic
separation implemented with wavelength-selective filters.
Bandwidth-per-cabinet, -building or -end user can be scaled nearly
indefinitely, while the reach can be extended to 100km or more. The
combination of secure traffic separation, scalable bandwidth and
extended reach enables carriers to serve a wider customer base from
fewer active sites. It eliminates the need for purpose-built
platforms and allows a streamlined network operation with fewer
operational staff.
In times where the cost of energy to run network equipment and to
climate-control the facilities that house them is skyrocketing, the
elimination of active equipment and reduction in number of active
network sites is attractive. But service providers can become more
independent of rising energy costs with the integrated access and
backhaul network approach that the FSP 3000 enables. A cohesive
Optical+Ethernet transport approach with WDM-PON extension can
deliver residential, business and wireless applications from a single
platform. It is an ideal solution for communications providers
looking for a future-proof network architecture.
