Mô tả Sản phẩm
  • Optical Wavelength: Typically operates in the 1100-1600nm range, with a specific focus on the 1550nm wavelength, which is commonly used for CATV signals.

  • Optical Input Power: It has an input power range for digital signals as low as -18dBm, which is a key high-performance feature. The range for analog signals is typically around 0dBm to -10dBm.

  • Automatic Gain Control (AGC): A significant feature of the OR18D is its optical AGC function. This allows the device to automatically adjust its output level to a consistent standard, even if the incoming optical signal power fluctuates within a specific range (e.g., 0 to -18dBm). This ensures a stable and high-quality signal for the user.

  • Output: It has a single or dual RF (Radio Frequency) output with a 75Ω impedance.

  • Other Features:

    • Low power consumption (typically less than 2W).

    • Use of GaAs (Gallium Arsenide) low-noise amplifier circuits for better signal quality.

    • Built-in multi-stage lightning protection to ensure safe operation.

    • Plastic shell with a through-hole design for good heat dissipation.
