Note:
The prices in the table are for reference only, and the actual prices may fluctuate depending on the supplier and market conditions.
G657A2 fiber is typically more expensive than G657A1 fiber, and G652D fiber is typically less expensive than G657A1 fiber.
The more cores, the higher the price of the drop cable.
3. Usage Methods
Aerial Deployment
When deploying aerial, consider the following:
Suspend the drop cable in the center of the pole or building facade, avoiding direct sunlight.
Maintain the appropriate distance between the drop cable and the pole or building facade.
Use appropriate hanging devices for the drop cable and regularly check their security.
Buried Deployment
When deploying buried, consider the following:
Bury the drop cable at a certain depth to avoid mechanical damage.
Install the drop cable in a straight pipe or cable trench, avoiding areas with sharp objects.
Seal the drop cable joints to be waterproof.
Duct Deployment
When deploying in ducts, consider the following:
Choose a drop cable of appropriate size and ensure the duct is clean and dry.
Pull the drop cable into the duct using appropriate pulling equipment and lubricants.
Secure the drop cable at the duct entrances to prevent movement.
4. Precautions
During installation and maintenance, handle the drop cable with care to avoid damage.
Do not exceed the maximum allowable pulling tension of the drop cable.
Protect the drop cable from sharp objects and excessive bending.
Store the drop cable in a clean and dry environment before and after installation.
