Transmitter CATV optic TERRA mo428 4D31 (2x6dBm, 1310nm)

The TERRA mo428 4D31 R82523 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 signals. The power of the optical signal at each of the two independent optical outputs 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 point-to-point links, the transmission distance can reach 40 km.The R82523 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 0.4A). With more devices, the optimum power source is the dedicated power supply DR-60-12 R82532.We also offer TERRA mo418 4D31 R82522 transmitter with one 6 dBm optical output.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.Application examplesTransmission of optical signals at 1310 nm and 1550 nm via a single fiber, with distribution to four subnetworksReception and distribution of four DVB-T multiplexes via optical medium, with redistribution to four subnetworksKey features For distribution of DVB-S/S2 (SAT IF) and TV signals (CATV, MATV) Two independent optical outputs, each with 6 dBm output level Input frequency range: 47-2400 MHz RF input with loop out AGC mode Max input level: 85 dBμV, Manual gain control: 0...-15 dB (1 dB step) Digitally controlled with front panel buttons Two-position display DIN rail or wall mounting Connectors: 3x F-f (RF input/RF loop output and RF TEST), 2x SC/APC (optical).Customers can order any patch cords made to order with required terminating connectors.
