DarkStar Line Amplifier

Product Overview

XKL’s DarkStar Line Amplifier is a fully-integrated optical amplifier solution that extends the reach of a network. High gain and low noise stem from its multi-stage amplifier design. And as with the rest of the XKL product line, the DLA is based on XKL’s DarkStar architecture, the foundation for addressing today’s IT challenges and scalable growth.

The DLA system integrates all the required components to create a metro, regional, or long-haul optical network, including Erbium- Doped Fiber Amplifiers (EDFAs), Raman Amplifiers, active or passive tilt and equalization filters, OTDR, as well as Dispersion Compensation Modules (DCMs).

DCMs are passive, Fiber Bragg Grating (FBG) based filters that provide the necessary dispersion compensation for any customer fiber type, and are typically required for transmission systems using direct-detect transceivers.

The DarkStar Line Amplifier system fits into 2 rack units (2U) of space and typically uses under 90 watts of power. Easy to integrate and operate, there is no need for specialized optical engineers to ensure network optimization. The DLA includes a Mid Stage access port on the front panel. This allows support for add/drop or North/South routes.
