SparkLight WDM system integrates SDH, CWDM and DWDM
technology in one platform. Each service can be established using
the DWDM, CWDM or SDH/SONET components in any mix, which enables
tailor-made networks supporting each individual business case.
SparkLight WDM solution is a powerful toolbox with unprecedented
high inherent flexibility targeting any metro, regional and medium
haul networks in the most cost-effective manner.
SparkLight WDM combines the benefits from all three technologies:
DWDM: A transparent, multi-service and high capacity transport
layer using an unique system architecture that does not require
CWDM: A low-cost transport solution with less requirements on
distance, management functionality etc. utilizing CWDM wavelengths.
SDH: MuxFeeder is a compact, cost-efficient SDH solution for
collection of e.g. STM-1 signals in ADM chains utilizing CWDM
and/or DWDM wavelengths.
Unique system of optical amplifiers elimination enables true integration
of DWDM and CWDM on the same fiber. It drastically reduces the network
cost and enables network scalability (pay-as-you-grow approach).
Purpose of the family
Building a Future-proof Optical Transmission Network that Supports
Your Business From the Start.
As a network designer you often wish to create the ultimate transmission
network covering anything from carrier-class connections with high
availability to shorter, straight-forward links where low cost is
more important than scalability and manageability.
The consequence is lower utilization of the fiber network and higher
operational costs due to the mix of different equipment, vendors and
inter-working restrictions in and between the different management
With the SparkLight WDM optical transport platform, you can now combine
the benefits from different transport technologies as plug-in units
into one single system, sharing the same card cage and same fiber
pair. All the system can be managed by SparkView network element management

One System Platform for all Networks and
Based on the Iskra Transmission unique system architecture where standard
DWDM components are brought together in a new constellation where
the optical losses are reduced to more than 50 %. As a result the
need for optical line amplifiers has been removed.
The benefits of DWDM solutions can now be implemented with an entry
cost that is up to 60 % lower than conventional DWDM systems, which
require optical line amplifiers.
Some of the key parameters of the SparkLight WDM DWDM component are:
Any topology - point-to-point, bus and ring
topologies in any mix
High capacity - up to 40 wavelength channels,
each capable of up to 10 Gb/s
High utilization - utilize each wavelength
with up to 16 aggregated traffic channels
Transparency - no statistical multiplexing
that reduces throughput. Transparent transport of OH information
in SDH/SONET traffic
Multi-service support - any traffic type ranging
from 100 Mb/s to 10 Gb/s
Flexibility - Easy to tailor to the optimum
configuration via a menu of plug-in units
CWDM is intended for networks that start out with lower capacity demands,
shorter distances and where initial cost is extremely important. With
the Iskra Transmission CWDM concept this can be done without sacrificing
the option to later upgrade with DWDM wavelengths in order to achieve
higher capacity and longer distances in the same network.
Any topology - point-to-point, bus and ring topologies in any
Medium capacity - up to 8 or 16 wavelength channels, each capable
of up to 2.5 Gb/s capacity
High utilization - utilize each wavelength with up to 16 aggregated
The SparkLight WDM MuxFeeder is a low-cost solution for collection
of STM-1/OC-3 and STM-4/OC-12. The basic functional unit in the MuxFeeder
application is the SDH/SONET MuxPonder. This single-board, plug-in
unit is a complete STM-16/OC-48 add/drop Multiplexer (ADM) or Terminal
Multiplexer with the functionality required to perform the aggregation
and transportation required in e.g. 3G mobile networks and other access
networks using the SDH/SONET frame for transport. The MuxPonder board
removes the need and cost of having a separate SDH/SONET system to
perform this task. The MuxPonder board is used side by side with other
CWDM and DWDM units in the same system in order to provide a true
multi-service transport platform.
The SparkLight WDM management architecture is designed for maximum
user flexibility and scalability where both the metro management system
(MMS) and the embedded node management (ENM) can be integrated with
existing operations support systems or network management systems
(OSS/NMS). For small optical networks the entry cost is held to a
minimum as the networks may be fully managed by the ENM only.
