Optická krabice Televes s až 4 výstupy OB4BLC

The Televes OB4BLC Optical Box is a high-performance optical-to-RF converter designed for distributing satellite and terrestrial signals over fiber optic networks. With up to 4 RF outputs, it provides reliable signal conversion for multi-dwelling units, hotels, and commercial installations.

Advantages

Supports both satellite (950-2400 MHz) and terrestrial (47-862 MHz) signals; compact die-cast Zamak housing ensures durability; low noise figure (<8 dB) for satellite signals; high isolation between outputs (>25 dB) prevents interference.

Suitable for

• Fiber-to-the-home (FTTH) distribution systems
• Multi-dwelling units (MDUs)
• Hotel and hospitality TV distribution
• Commercial satellite and terrestrial signal distribution
