This makes it possible to distribute satellite and CATV signals over a single fiber to multiple optical receivers.\u003c\/p\u003e\n\u003cp\u003eBuilt-in Automatic Gain Control (AGC, 15 dB) and Automatic Slope Control (ASC, 10 dB) continuously adjust the output to maintain optimal signal quality regardless of input level variations. The transmitter is compatible with optical networks scaled from small (up to 64 splits) through medium (up to 255 splits) to very large (more than 2000 splits) deployments.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n\u003cli\u003eRF inputs: 2 x Satellite F-connector (Wideband or Quattro) and 1 x CATV F-connector\u003c\/li\u003e\n\u003cli\u003eSAT input frequency range: 290–2340 MHz (Wideband) \/ 950–2150 MHz (Quattro)\u003c\/li\u003e\n\u003cli\u003eCATV input frequency range: 47–1218 MHz\u003c\/li\u003e\n\u003cli\u003e1 optical output (SC\/APC) with three simultaneous wavelengths: 1310, 1330, and 1550 nm\u003c\/li\u003e\n\u003cli\u003eOptical output power: 9 dBm per wavelength\u003c\/li\u003e\n\u003cli\u003eAutomatic Gain Control (AGC): 15 dB range\u003c\/li\u003e\n\u003cli\u003eAutomatic Slope Control (ASC): 10 dB range\u003c\/li\u003e\n\u003cli\u003eDC supply SAT: 18 V \/ 400 mA; DC supply CATV: 12 V \/ 200 mA\u003c\/li\u003e\n\u003cli\u003eDC input: 20 V \/ 1.5 A via F-type connector (requires external 20 V \/ 3 A power supply, ref. 2460, not included)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eProduct Benefits\u003c\/h4\u003e\n\u003cul\u003e\n\u003cli\u003eThree wavelengths on one fiber allow separate SAT and CATV signals to reach optical receivers without additional multiplexers\u003c\/li\u003e\n\u003cli\u003eAGC compensates for input level variations of up to 15 dB, ensuring stable optical output without manual adjustment\u003c\/li\u003e\n\u003cli\u003eASC corrects the frequency slope of the input signal for flatter output across the entire bandwidth\u003c\/li\u003e\n\u003cli\u003ePlug-and-play design minimises installation time — no complex alignment or calibration required\u003c\/li\u003e\n\u003cli\u003eScalable architecture supports everything from a single building to large multi-dwelling installations with more than 2000 optical splits\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eModel:\u003c\/strong\u003e Johansson 4003\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRF Inputs (F-connector):\u003c\/strong\u003e 2 x Satellite (Wideband \/ Quattro), 1 x CATV\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSAT Input Frequency:\u003c\/strong\u003e 290–2340 MHz (Wideband) \/ 950–2150 MHz (Quattro)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCATV Input Frequency:\u003c\/strong\u003e 47–1218 MHz\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOptical Outputs (SC\/APC):\u003c\/strong\u003e 1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOptical Wavelengths:\u003c\/strong\u003e 1310, 1330, and 1550 nm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOptical Output Power:\u003c\/strong\u003e 9 dBm (per wavelength)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMin.
