Types of headends
DCRF(dry creek road facility)The headend
Serves as a gateway to both the public internet and Comcasts own managed nationwide network
Collects signals from a variety of sources, such as satellite feeds, and directs them to headend
Benefits of using fiber optic cable for transportation of signals
Low signal loss,Greater bandwidth,Increased security, Flexibility and durability
Benefits of the hfc network
Enhanced signal quality, Increased network reliability, Increased flexibility to quickly launch new and complex services
Transforms light energy from optical cable to RF or electrical energy on the coaxial output
Transports modulated light between the fiber node and the headend
Fiber optic link
Used for routing or splitting signals. Does not require power to operate
Allows signals to and from the customer in this part of the network. Provides the conversion from the fiber optical cable to coaxial cable
Is connected to the coax cable. The RF energy is used to modulate the laser emission.it uses special lenses to focus light into the fiber optic cable.
Carries signals to and from the node through the hardline coaxial cable to communities for connection to the customer drop
