1.3.2 Amplification Systems (DBA-L & DRA)
Each amplification type and its manner of deployment has unique characteristics and benefits. The amplification technology
and configuration used will depend upon transmission distances, network topology, and fiber type, among other factors that
are taken into account when building a system.
Information related to setting up an amplifier can be found in “Amplifier Configuration” on page 36. Amplification systems
share much of the same hardware and software as other DarkStar products, requiring only one set of general operating
instructions and commands to manage DarkStar products efficiently.
Beyond standalone amplifiers, some amplification technologies may be directly integrated into optical networking systems.
DarkStar networks and systems currently support two types of amplification:
1.
EDFA (Erbium Doped Fiber Amplifier).
2.
Raman.
Amplifiers generally serve three purposes in a system:
•
Booster:
Increase signal power into the fiber.
