Brief: Let’s dive in — see this solution in action and notice the key moments. In this video, we showcase the Gezhi Dual Fiber 40CH AAWG Athermal Arrayed Waveguide Grating in operation. You'll see a detailed walkthrough of its high-density, low-loss passive optical module design, demonstrating how it provides reliable WDM multiplexing and demultiplexing for data center and metro network applications without requiring power or cooling.
Related Product Features:
  • Completely passive operation requiring no power or cooling for enhanced reliability.
  • High channel isolation exceeding 30 dB for adjacent channels ensures signal integrity.
  • Built-in multiplexer and demultiplexer functionality operates on two network fibers.
  • Ultra-low insertion loss below 4.5 dB maximizes transmission distance and performance.
  • Athermal AWG technology with Gaussian design provides excellent wavelength stability.
  • Designed for high-density applications in a standard 19-inch 1U rack mount frame.
  • Supports 40 channels with 100 GHz spacing across the C-band wavelength range.
  • Ideal for WDM transmission, optical signal processing, and metro network architectures.
Ч.З.В.:
  • What are the key advantages of the athermal AWG technology used in this module?
    The athermal AWG technology eliminates the need for active temperature control, providing excellent wavelength stability within ±0.05 nm across operating temperatures from -5°C to 65°C, ensuring reliable performance without power consumption.
  • How does this 40-channel AAWG module handle multiplexing and demultiplexing?
    This dual fiber module features built-in multiplexer and demultiplexer functionality in a single unit, working on two network fibers to combine and separate 40 optical channels with high isolation and low insertion loss.
  • What types of network applications is this AAWG module suitable for?
    It's ideal for WDM-based add-drop multiplexing, optical signal processing, wavelength selective routing, and both metro and long-haul network applications, particularly in data centers requiring high channel counts.
  • What are the optical performance specifications for insertion loss and channel isolation?
    The module offers ultra-low insertion loss between 3.5-4.5 dB, adjacent channel isolation of 30 dB minimum, non-adjacent isolation of 40 dB minimum, and total channel isolation of 33 dB minimum for superior signal quality.
