DSV-42
DSV-42
The DSV-42 is a 75 Ohm, three port, RF multiplexer. It may be used either to combine or to separate two bands of frequencies (DC to 42 / 54 to 1000 MHz). This frequency selective device provides a lower loss method of combining/separating signals than a conventional hybrid splitter. Internal filters provide a great degree of isolation between those bands. That isolation is necessary to prevent input overload of active devices located in the headend or distribution system where such signals are joined. DSV-42 applications include sub-split, bi-directional systems. These are usually LAN or CATV networks distributing data or video in the reverse direction via the sub-channel band.
