Passive Optical Newtork (PON) technology is rapidly emerging as the solution of choice for access networks such as fiber to the home (FTTH). Santec's TPF-15 Triple Play Filter is designed to add/drop a 1540-1560nm channel to a standard 1310/1490nm PON network. The 1550nm channel can be used for analogue or digital video or for wavelength division multiplexed (WDM) channels. The filter can be installed in either the central office OLT or the ONU at the customer's premises. Standard and high isolation versions are available.
