Summary:In optical telecommunications networks using passive optical networks (PON), an optical wavelength band called the enhancement band (1539 to 1565 nm) is typically used to carry broadcast video signals in either analog television or QAM Digital Video form. This enhancement band is used here to carry a unidirectional baseband Ethernet signal, such as Gigabit Ethernet, in the optical domain to all or a subset of subscriber premises to carry broadband services from, for instance, a video on demand distribution facility. This results in a network with all digital baseband signaling and simplifies the network architecture so as to be all Internet Protocol and/or all Ethernet compatible.
