OSP Cable Installation Basics

Front

What are the main types of OSP cable installations?

Back

Underground (in conduit), Direct Buried, Aerial, Submarine/Underwater, Microtrenching.

Front

What is a key consideration for underground cable installation?

Back

Use of conduit, high pulling tension design, and planning for excess cable for splicing.

Front

Why is direct buried cable armored?

Back

To protect against rodent damage and pressure from rocks and soil.

Front

What is microtrenching?

Back

A method using shallow, narrow cuts (25mm wide, 200–250mm deep) for installing fiber, often used in FTTH.

Front

What is an all-dielectric self-supporting (ADSS) cable?

Back

Aerial cable that doesn't require a messenger wire and is supported using special pole hardware.

Front

What type of fiber is most common in OSP installations?

Back

Singlemode fiber (usually G.652).

Front

What is the benefit of including extra fibers in a cable?

Back

Future expansion, backups, or repair flexibility at a low cost increase.

Front

Why are dry water-blocked cables preferred over gel-filled?

Back

Easier, cleaner splicing and preparation.

Front

What is the purpose of a splice tray?

Back

To securely hold and protect fiber splices inside a closure or panel.

Front

What is the typical method for singlemode fiber termination?

Back

Fusion splicing to pre-terminated pigtails.
