Satellite Fiber Optic Transmitter

Satellite Wideband Twin LNB Fiber Optic Transmitter

Overview

The Satellite Wideband Twin LNB Fiber Optic Transmitter is a high-performance device that converts satellite wideband horizontal, wideband vertical RF, and terrestrial TV RF into a single-mode fiber output while providing 14V DC reverse power to the twin LNB. This transmitter is designed for high-capacity satellite TV distribution, with optical output versions supporting 1×32, 1×128, or 1×256 fiber-to-the-home (FTTH) optical receivers directly.

Features

• Compact aluminum die-cast housing for durability.

• Three RF inputs: Wideband Horizontal, Wideband Vertical, and Terrestrial TV.

• Wideband Frequency Support:

  • Vertical: 300~2350MHz (VL and VH Quattro equivalent).

  • Horizontal: 300~2350MHz (HL and HH Quattro equivalent).

  • Terrestrial TV: 88~250MHz (UHF 470~806MHz TV channels converted into 170~250MHz VHF by GTC250 Terrestrial TV frequency converter)
