Details

Optical transmitter mo428 4D31 TERRA R82523 is used for transmission of television signals using fiber optic medium. The device converts electrical signal (coaxial cable) into optical signal. The power at the optical output of 6 dBm (4 mW) allows for the distribution of television signals from several to a dozen distribution points - depending on the sensitivity of the equipment on the receiving end. In the case of point-to-point connections, the transmission range can reach up to 40 km. The device is equipped with two independent optical transmitters.
The mo428 4D31 TERRA R82523 transmitter uses a wavelength of 1310 nm (II window) for transmission, and can be mounted individually, e.g. on a wall using the included accessories, or in sets on the universal DIN rail R82538 with the possibility of mounting in RACK cabinets. The device is supplied with 12 V at a current consumption of 0.4 A. A single transmitter may be powered from any power supply unit with the specified current capacity and output voltage. For larger numbers of devices, we recommend the DR-60-12 R82532 dedicated power supply unit.
A mo418 4D31 R82522 transmitter with 1 optical output of 6 dBm is also available.
On request, there are available transmitters operating in the 3rd transmission window (1550 nm):
