### 4. Functionality
Operating Principle:
The FAT-LC-SS05 attenuator functions by introducing a controlled optical loss into the transmission path. It reduces the intensity of the optical signal without distorting its waveform, thereby preventing receiver saturation or damage in high-power optical links.
Use Cases and Applications:
- Short-distance fiber connections: When two high-power transceivers are connected over a short fiber link, the received optical power may exceed the receiver’s maximum input threshold. The FAT-LC-SS05 mitigates this by reducing the signal strength by 5 dB.
- Optical power balancing: Used to equalize signal levels across multiple channels in WDM (Wavelength Division Multiplexing) systems.
- Testing and calibration: Ideal for laboratory environments where controlled attenuation is required for equipment testing and calibration.
- Industrial and telecom networks: Suitable for use in industrial Ethernet, telecom backbones, and data center interconnects.
Compatibility:
- Fully compatible with ORing’s SFP100 and SFP1G series transceivers, including models such as SFP100-SS30, SFP100-SS60, SFP1G-LX10, SFP1G-LHX30, and SFP1G-ZX70.
