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 the optical input -15...-5 dBm,
- die-cast housing ensuring a high level of shielding – class A,
- OLC – automatic control stabilizing the signal level,
- LEDs on the housing for much easier configuration of the entire system,
- DC power supply directly from the connected multiswitch or an external DC power supply 10...20 V, which is optional equipment.
DIPOL also offers optical receivers for building systems based on traditional multiswitches, dSCR/Unicable, as well as hybrid systems:
Customers can order any patch cords made to order with required terminating connectors. Please contact your sales assistant.
