发明名称 Tap-off capable of easily extending hybrid fiber coaxial (HFC) network
摘要 A tap-off capable of easily extending a hybrid fiber coaxial network without complicated cable handling and signal disruptions. The tap-off comprises a primary distributor connected to a directional coupler. Additional distributors are divergently connected to the primary distributor and include terminal distributors. Bridges are divergently connected to the terminal distributors, and an intermediate distributor is connected between the directional coupler and the primary distributor. The tap-off also has at least one extension port and at least one intermediate cable connecting the extension port with the intermediate distributor. Each bridge is connected to a drop cable for providing a signal to a subscriber. The intermediate distributor distributes the signal to the primary distributor and to the extension port. The tap-off further comprises an additional extension tap-off, which includes an input port connected to the extension port, distributors, and bridges.
