The TERRA mo418 4D31 R82522 optical transmitter is used for transmission of television signals via optical medium. It converts input electrical signals within 47-2400 MHz range, fed with coaxial cable, into optical signal. The power of the optical signal is 6 dBm (4 mW), which is sufficient for feeding several to ten or so nodes (depending on the sensitivity of the receivers). In the case of a point-to-point link, the transmission distance can reach 40 km.
The R82522 transmitter operates at 1310 nm wavelength (2nd transmission window). It can be mounted separately on a wall, using the included accessories, or can be placed together with other devices on universal DIN rail R82538 (also in a RACK cabinet). The device is powered from a 12 VDC source with suitable current capacity (the current consumption is typically 0.35A). With more devices, the optimum power source is the dedicated power supply DR-60-12 R82532.
We also offer TERRA mo428 4D31 R82523 transmitter equipped with two independent 6 dBm optical outputs.
On request, there are available transmitters operating in the 3rd transmission window (1550 nm):
| Name | mo418 4D31 | mo428 4D31 | mo418 4D55 | mo428 4D55 |
| Number of optical outputs | 1 | 2 | 1 | 2 |
| Output level [dBm] | 1x6 | 2x6 | 1x6 | 2x6 |
| Wavelength [nm] | 1310 | 1310 | 1550 | 1550 |
A great advantage of the device is the ability of integration with other pieces of equipment, such as:
- optical splitters - distribution of optical signal to several locations
- WDM diplexers - transmission of signals at 1310 nm and 1550 nm via a single fiber
- RF signal processing equipment (broadband and channel amplifiers, analog TV and DVB-T modulators)
The transmitter can be placed together with other devices on universal DIN rail, also in a RACK cabinet.
