6350 Switch Node
A High Capacity MSPP and WDM Feeder
The Coriant 6350 Switch Node is a high capacity Multi-Service Provisioning Platform
(MSPP) designed for Metro/Core networks. TDM and data services are mapped and
multiplexed into SDH and OTN, and carried over the optical transport network. Also,
10G transponders are supported for transparent transport of 10G services (Ethernet,
SDH or OTN) over an OTU2 line signal.
APPLICATIONS
The 6350 Switch Node is often located at the edge of metro/core networks. Ethernet
switching and Lower Order grooming capabilities ensure that traffic resources are
utilized efficiently when carried over the optical transport network. Backhauling and
offloading IP connectivity from the edge to the IP core is another application for the
6350 Switch Node. Easily scalable bandwidth and low latency are key features when
Ethernet is mapped into SDH/OTN, enabling real time data services to be carried over
long distances.
With the high number of 10G ports, the 6350 Switch Node is an efficient feeder that
can feed multiple 10G rings and acts as an efficient feeder to WDM systems where
line interfaces are carried over same fiber pairs in individual WDM wavelengths.
Services are either carried transparently using the transponder modules or
multiplexed into wavelength specific 10G STM-64/OTU2 signals. In combination with
other MSPP and WDM products from the Coriant 6300 Series, the 6350 Switch Node
typically acts as an aggregation node collecting traffic from a high number of 6325
Edge Nodes and 6335 Switch Nodes that are either customer-located or deployed in
access networks.
HIGH AVAILABILITY AND FULL REDUNDANCY
The 6350 Switch Node is designed as a carrier class product with a completely
redundant architecture ensuring high availability. Core modules as well as traffic
interfaces are all equipment protected or protected utilizing standard optical network
protection schemes.
FLEXIBLE, MODULAR DESIGN
The product has a modular design with 20 interface slots that can be equipped with a
range of traffic modules: electrical or optical, data or TDM services to be multiplexed
in the centralized cross-connection matrices or carried as transparent signals. Acting
as a Multiple Add/Drop Multiplexer (MADM), the node handles all services in a fully
non-blocking cross-connection matrix with a capacity of 400 Gbps. The product also
supports up to 40 x STM-64 or a combination of 160 x STM-16/4/1 interfaces.
Ethernet services are either mapped directly into SDH or handled in the Layer 2
Ethernet switch before being mapped into SDH. The Ethernet switching includes hard
quality of service (QoS) with guaranteed services end-to-end with MPLS switching
enabled. QoS using VLAN switching is another option. All optical interfaces are
realized using pluggable or tunable optics. This offers high flexibility as the same
interface module can be equipped with a range of pluggable transceivers for different
applications: short range, long range, bi-directional over single fiber, CWDM or DWDM.
