SC/APC Optical Receiver/Demultiplexer (-8…+1dBm)…
KSh58,136.00
The FTTH receiver captures two satellite signals on a single fiber and demultiplexes them. The first one, in the wavelength 1310nm carries the dCSS satellite channels using an optical LNB (satellite operator SKY) while the second one in 1550nm, carries the DTT lineup plus a satellite offer using a second dish and a static dLNB.
The FTTH receiver has a physical switch that allows to select between dCSS SKY mode and FTA SAT mode. Depending of the selected choice, one of the two satellite signals plus the DTT lineup is delivered in the four RF outputs. In case of dCSS SKY mode, with the use of a single power supply, it powers up the dCSS optical converter (Ref. 237201).
Part of FULL SAT + DTT system to be used together with the FTTH transmitter televes-237301.
Highlights
DIN rail installation: this assembly provides safety and efficiency, as well as saving space, time and cost due its advantage by being able to integrate several electrical devices in an installation with a lower cabling density. It is also possible to mount it screwed on the wall
Distribution mode flexibility: a switch is included to choose between DTT+Satellite IF or DTT+dCSS/Legacy
High sensitivity in 1550 nm
High output voltage in the 4 RF outputs
Eco-Mode powering with dCSS SKY mode selected: if the STB is switched-off, it ceases to power up the dCSS optical converter, just delivering the DTT lineup with a very low power consumption
Features
Compatible with Legacy and dCSS multiswitches
Equipped with a power supply output to feed an optical converter
Very pleasant and compact format
