The OT 5 CWDM channel from Polytron Receives coax signals in the range of 47-2150 MHz and converts it into an optical signal in the range of 1510-1570 nm. This is then distributed via an optical distribution network. The optical signal is then via the OR 5 QT (Quattro) or OR 4 S (Quad) Receive and reconnected to a coaxial RF signal, these receivers are not supplied and must be purchased separately.
The distribution of satellite signals via fiber optic cables offers technical and economic benefits. Economic Because the fiber optic cables are already a lot more cheaper and you need fewer cables, so you will soon need 4 cables for a Quattro LNB to 1 fiber cable.
In addition, the technical seen also gives several advantages, since fiber optic has a very low damping at longer distances. This makes it easy to bridge longer lengths and to create larger distribution networks. Fiber optic also has a very high data capacity, which means that more data can be sent at the same time.
CWDM stands for conventional / coarse wavelength division multiplexing, which means wavelength multiplexing in Dutch, with this it makes it possible to send several and different wavelengths to a single fiber cable at a single fiber. The Wavelgths that Polytron For this, it is used for this to be 1510 nm, 1530 nm, 1550 nm, 1570 nm. This makes it possible to fully forward 4 polarizations over an optical cable.
The transmitter has 4 satellite inputs and 1 terrestrial / DAB + input.
The OT 5 CWDM can work with a quad or quattro LNB and is therefore suitable for use on, for example, a ship with a tracking system with only a quad LNB. This will send the 13V / 18V and 22 kHz so that it will work as a quattro LNB and can therefore work with a multiswitch.
This transmitter is equipped with an optical output with a SC / APC connector (green).
This product is powered by an external supplied power supply that is 20V DC and supplies 2.5A to power. This makes the maximum consumed power 8W. This power supply is provided with a femal F-connector connection.
