Distribution network

• In a hybrid fiber-coaxial (HFC) architecture, optical fiber replaces trunk portion of the distribution network.

• Small service areas, each with from as few as 100 to as many as 2,000 homes passed.

• Fiber connects between the headend (or hub) and an optical node, where light is converted to RF.

• From the node, RF signals are distributed throughout the serving area via coaxial cable.

The distribution network is made up of fiber and coaxial cabling, which carry television signals toward the subscriber. The last part, and also one of the most infamous parts of the cable network, is the subscriber drop. The subscriber drop includes the following:

■ Everything from the connection to the feeder out of the utility pole

Set-top box

Grounding and attachment hardware

Cable

All the bits and pieces that make that final connection work
