... transmission, an optical receiver node converts the optical signal into a signal for further distribution. As with standard coax system, in optical communications, directional couplers and splitters are used to split the optical signal in the headend for more efficient transmission. The use in the headend of these devices has been important in reducing the cost of fiber systems by allowing a single laser to be shared among multiple receivers. The smallest, final span of cable, called the drop, i ...
