The Johansson 4032 is a dSCR/legacy Quad Optical Convertor developed to help installers overcome low signal quality in satellite fiber installations. It accepts a single SC/APC optical input carrying three wavelengths (1310 nm, 1330 nm, 1550 nm) and converts them to five RF outputs with AGC on all ports.

In Quad mode, the device delivers 4 x dSCR/legacy outputs plus a terrestrial output, supporting up to 128 splits and 4 x 16 dCSS/dSCR user bands. In Quattro mode it serves as a satellite trunk output, converting the three wavelengths to VL, HL, VH, HH, and TERR — compatible with Sky UK and standard EN50494/EN50607 systems.

Key Features

• Dual operating modes: Quad (4 x dSCR/Legacy + TERR) and Quattro (VL, HL, VH, HH, TERR)
• Three optical wavelengths: 1310 nm (V), 1330 nm (H), 1550 nm (T)
• Five RF outputs, all with AGC for stable output levels
• Signal quality indicator LED per optical wavelength
• Supports up to 128 splits in Quad mode
• Sky compatible; supports DiSEqC 1.0, DiSEqC 2.0, EN50494/EN50607, and SKY UK protocol
• Band and polarity selection via Universal LNB Voltage and Tone

Product Benefits

• AGC on all output ports maintains consistent signal levels regardless of input variation
• Quad mode enables multi-receiver installations from a single fiber run
• Quattro mode allows the unit to act as a satellite trunk for further downstream distribution
• Per-wavelength LED indicators allow fast fault diagnosis during installation
• Sky UK protocol compatibility broadens deployment to Sky satellite systems
