The following steps should be followed for the proper installation of OPGW cables:

Step 1: Conduct a survey of the area where the cable is to be installed. The survey should take into account the terrain, weather, and other external factors.

Step 2: Choose the appropriate installation technique. OPGW cables can be installed using one of the following methods: aerial, trenching, plowing, directional boring, and cable pulling.

Step 3: Prepare the site for installation. The site should be cleared of any debris that may interfere with the cable installation.

Step 4: Install the cable. The cable should be installed using a tension method to avoid sagging and ensure proper alignment.

Step 5: Terminate and splice the cable. The cable should be terminated and spliced according to manufacturer specifications to ensure reliable transmission of signals and power.

Step 6: Test the cable. The cable should be tested for continuity, insulation resistance, and other electrical parameters to ensure proper functioning.

3. What are the safety precautions that should be taken during installation?

The following safety precautions should be taken during the installation of OPGW cables:

- Use appropriate personal protective equipment (PPE) such as gloves, safety glasses, and hard hats.

- Follow and abide by all safety regulations and guidelines.

- Ensure that the site is properly marked and secured to prevent accidental contact with the cable.

- Do not work on or near the cable during electrical storms or adverse weather conditions.
