Capital Efficiency Through Nodal Cost Reduction
Transparent switching enables the bypass of
opto-electronic interfaces on express connections at all network nodes.
Wavelengths passing through intermediate nodes experience 90% lower cost
when compared to conventional solutions that require OEO transitions between
line systems. In today's core networks, more than 70% of cost resides
in the network nodes due to the line efficiencies gained with modern DWDM
systems through reduced regeneration and amplifier costs. Managing the
wavelength traffic that passes through major nodes (nearly 75% of the
total) with transparent photonic switching dramatically reduces nodal
costs, resulting in network savings of up to 50% relative to alternative
next generation DWDM solutions.
Simplifying
Network Scale
Scaling to Terabit capacity puts significant strain on the cost and facilities
required at the network's hubs. The TPX 1000 interfaces at the multiplexed
section and switches at the individual wavelength level; this means cabling
for pass-through wavelengths is eliminated resulting in a 70-95% net reduction
of intra-office cabling. For what cabling is required, embedded connection
trace capability creates intelligent patch cords that enable automated
connection management and troubleshooting as part of the automatic self-test
and turn-up tool-kit. Nodal scale can be realized with switch scaling
up to 32 Tb/s with a density of 4 Tb/s per NEBS rack. Power requirements
are 70% less than that required by OEO switches. Switch scalability is
non-intrusive and is performed with simple module and shelf addition to
the in-service elements.
Enabling
Network Flexibility
The TPX 1000 combines advances in photonic switching with intelligent
optical signaling technologies. To network a wavelength requires the ability
to accommodate various path-based degradations for connections traversing
multiple fiber spans and intermediate switching nodes. The switches' inherent
low insertion loss and distortion minimizes the impact on pass-through
wavelengths. The “colorless” nature of the TPX 1000, coupled
with flexible connectivity, reduces the risk of stranding resources, and
allows the full add/drop capacity to be used from any line incident to
a node.
Balancing
Technology Platforms
By performing wavelength level switching photonically, a nodal hierarchy
is created where only those wavelengths which require electrical-level
functions drop down to the layer served by their networking device (cross-connects,
routers or add/drop multiplexers). Layering the networking in this fashion
alleviates the scaling burden on the networking appliances and allows
them to be optimized around performing higher order functions (grooming/muxing,
routing, switching, protection/restoration, etc.).
The AgileCore
TPX 1000 automates the core network and dramatically reduces network capital
and operation expenditures, while providing rapid bandwidth delivery anywhere
in the core.
