### 4. Functionality
The FAT-LC-SS20 functions as a passive optical component that reduces the intensity of an optical signal traveling through a single-mode fiber. It achieves this by introducing a controlled amount of optical loss (20 dB) into the transmission path. This attenuation is essential when the optical power output from a transmitter (such as an SFP or SFP+ module) exceeds the receiver’s maximum input power threshold.
Typical Use Cases:
- Short-Distance Fiber Links: When connecting two optical transceivers over short fiber runs (e.g., <1 km), the received optical power may exceed the receiver’s tolerance. The FAT-LC-SS20 ensures the signal is reduced to a safe level.
- High-Power Transmitter Protection: Used with long-range transceivers (e.g., 30–120 km SFP modules) during testing or short-distance deployment.
- Optical Network Testing: Provides controlled signal reduction for calibration and performance verification of optical systems.
- Telecommunication and Data Centers: Maintains optimal signal levels in dense optical distribution environments.
- Industrial Networking: Ensures reliable optical communication in ruggedized industrial Ethernet systems.
Compatibility:
- Compatible with LC-based single-mode transceivers such as ORing’s SFP100-SS30, SFP100-SS60, SFP1G-LX10, SFP1G-LHX30, and similar models.
- Works with standard LC patch cords (e.g., FPC-LCLC-SS3M) and LC adapters.
- Suitable for use with optical equipment operating at 1310 nm and 1550 nm wavelengths.
