Data Sheet

Cisco 1 GHz GainStar Line Extender with 85/105

MHz Split

The Cisco

®

1 GHz GainStar Line Extender (GSLE) is specifically designed for use in hybrid fiber-coaxial (HFC) networks. It provides excellent forward and reverse path performance combined with high reliability and a user-friendly layout. All new Cisco

GainStar products share common plug-in accessories and perform to 1 GHz in the forward path. The Cisco 1 GHz GSLE provides a single high-level output port or two lower-level RF output ports in a strand-mount configuration (Figure 1 and Figure 2).

The Cisco 1 GHz GSLE uses GaAsFET technology optimized for superior distortion performance.

Features

● 1-GHz performance

● Selectable single or dual outputs with an onboard signal director

● Standard plug-in attenuators that are used to adjust gain and equalization settings

● Surge-resistant circuitry that helps ensure resistance to high voltage transients (6 kV)

● Thermal RF control that reduces gain movement over temperature

● 10A current capacity (steady state) and 15A surge survivability

● Outdoor housing that is IP68 dustproof and watertight

● Strand-mount housing configurations available

● RoHS 6 of 6
