Terra's new TV/SAT signal distribution system is characterized by high quality and competitive price. The special features of the system are: compact dimensions of the devices allowing for convenient placing together with other elements of the system in TV cabinets, wide spectrum of devices for systems based on traditional multiswitches, dSCR/Unicable, as well as hybrid systems. The use of different versions of optical transmitters allows for the distribution of signals: DVB-T/T2 and satellite from two satellites in only 1 fiber.
The ORF202 E optical receiver A3131 allows the conversion of the optical signal coming from the OTF302 6F31 E A3031 or OTF302 6F55 E A3055 transmitter into an electrical signal. The signal is received from the optical transmitter via a passive fiber optic network and converted back to the original IF signal. The device contains 2 outputs, dividing the entire band into two polarizations (V - vertical, H - horizontal) - just like for a classic wideband converter. Such receivers are often known as "virtual converters". These signals should be fed into a dSCR-type multiswitch with the appropriate number of outputs, and then already via coaxial cable to the subscriber outlets. Behind the receiver, it is possible to build more complex, multi-multiswitch systems.
The ORF202 E TERRA A3131 optical receiver is compatible with the following transmitters:
Key features:
- wavelength 1100...1650 nm
- acceptable power level at optical input -15...-5 dBm
- cast housing guaranteeing high level of shielding - class A
- OLC - automatic control stabilising signal level
- LEDs on the casing greatly facilitating proper configuration of the whole system
- DC power supply is provided directly from the connected multiswitch or from an external DC 10...20 V power supply, which is not standard equipment
In DIPOL's offer there are also optical receivers available, allowing to build installations both based on traditional, dSCR/Unicable multiswitches, as well as hybrid installations:
Customers can order any patch cords made to order with required terminating connectors. Please contact your sales assistant.
