Advantages
This patch cable provides exceptional signal integrity with an insertion loss of less than 0.2dB, ensuring minimal data degradation over its 4-meter length. The inclusion of a high-quality ceramic ferrule enhances connection stability and durability. Furthermore, the cable is encased in a 2.0mm LSZH (Low Smoke Zero Halogen) yellow jacket, which improves safety in enclosed spaces by reducing toxic emissions in the event of fire. Each cable is supplied with an individual measurement protocol to verify its performance standards before deployment.

Enterprise local area networks (LAN)
Telecommunications infrastructure
Fiber-to-the-Home (FTTH) installations
High-density patch panel environments
This cable may not be suitable for outdoor environments where it would be exposed to direct sunlight, moisture, or extreme physical stress without additional protective conduit. It is specifically designed for indoor use and is not intended for high-vibration industrial machinery settings where ruggedized cabling would be required.

How to use
To install the cable, first ensure that the fiber optic ports on your networking equipment are clean and free of dust. Remove the protective caps from the CS-UPC and LC-UPC connectors. Carefully align the connector with the port and insert it until you hear a soft click, indicating a secure connection. Avoid bending the cable beyond its minimum bend radius to prevent signal loss or fiber damage. Once connected, route the cable through cable management systems to prevent tension on the connectors.
What to consider before purchase
Verify that your equipment supports CS and LC connector interfaces.
Ensure the 4-meter length is sufficient for your specific rack or device layout.
Confirm that your network environment requires OS2 singlemode fiber specifications.
Check if your local building codes mandate the use of LSZH-rated cabling.
Usage recommendations: Always inspect the connector end-faces for contamination before installation. Use a fiber optic cleaning tool if necessary to maintain optimal signal quality. Store the cable in a cool, dry place when not in use and keep the protective dust caps on the connectors to prevent scratches on the ceramic ferrule.
