buffer tubes - A flexible cylindrical structure that houses, compartmentalizes, and protects smaller groups of optical fibers within larger multi-fiber cables. pigtails - A length of optical fiber with a connector at only one end, which may be spliced to a smaller diameter optical fiber for testing or termination. acceptance testing - Length and loss test of fiber-optic cable that is typically performed twice—when the cable is received from the manufacturer and after the cable is i...

Customer premises - Connected to the network through distribution taps spliced into the coaxial cable. Branches in the architecture - The downstream signal is distributed within nearby neighborhoods using 0.412-inch to 0.625-inch diameter coaxial cable, splitters, and directional couplers. Bridger amplifier - A portion of the downstream signal is boosted before being split and routed to as many as four separate coaxial cables—the branches in the architecture. Trunk amplifiers - ...

In the tree-and-branch architecture, how is the downstream signal from the trunk fed to the distribution branches? - Within each trunk amplifier, a portion of the downstream is fed to a bridger amplifier to boost the signal before being split and routed to the distribution branches. What is a common solution when congestion from modem activity and traffic becomes unacceptable in a hybrid fiber/coax (HFC) network? - Node splitting, the subdividing of serving areas into two or more smaller ...

According to SCTE- and NCTA-recommended trunk system map symbols, fiber-optic cable is represented by - Double arrows within a small circle on a solid line. The forward path signal in a traditional tree-and-branch architecture - Originates at the headend and is transmitted downstream through coaxial trunk cable and trunk amplifiers. In an HFC network, - Processing equipment in the headend converts the forward RF signal to a light signal. During aerial plant construction, - The s...
