Introduction
1.1 Overview
The DarkStar family of products is an integrated suite of fiber-optic networking systems that can be used to create custom
fiber-optic network topologies to meet virtually any business need.
DarkStar products use Dense Wavelength Division Multiplexing (DWDM) optical network hardware and management
interface software to achieve data transmissions over extended distances at high data rates.
The DarkStar product line allows an enterprise complete control over its proprietary fiber-optic networks, allowing it to take
advantage of the increasing availability and economy of unlit or “dark” fiber. DarkStar networks allow businesses to
circumvent the exorbitant cost of leasing services and equipment. By developing and managing a DarkStar network directly,
businesses can create proprietary, carrier-class, fiber-optic networks with a significantly lower total cost of ownership.
DarkStar networks have therefore been designed for use by network administrators instead of optical engineers. The DarkStar
operating system offers a simple, command-line interface with router-like operation that will be familiar to any enterprise
network administrator.
1.1.1 Network
A DarkStar network consists of at least two Darkstar optical networking systems acting as endpoints. Additional DarkStar
networking systems, DarkStar amplifier systems, or DarkStar combiner systems can be added to enable extended network
designs, and enhance transport performance.
1.1.2 Amplification
DarkStar amplifier systems and amplifier components maximize the transmission distance of DarkStar networks. In general, a
simple network with paired optical networking systems supports transmission distances up to 70km; systems employing
amplification may achieve transmission distances up to 2000km.
1.1.3 Redundancy
DarkStar systems can provide redundant failover through model features, component specifications, and network design.
Consult XKL about the best ways to achieve redundant failover in your own network designs.
1.2 System Design
Requirements for designing a DarkStar network encompass more areas than can be detailed in this document. However, the
following information provides a brief overview of key features and considerations in the development of a system.
1.2.1 Applications
DarkStar systems can be used to build networks for metro, regional, or long-haul network access.
