What is a fiber optic aerial cable?

Blackstone Fiber optic aerial cables are used for high-speed data transmission over long distances. These cables are specifically designed to be installed above ground, either strung between poles or buildings, making them ideal for telecommunications, internet services, and other applications that require reliable and fast data transfer.

There are three main types of fiber optic aerial cables: Self-Supporting Aerial Cables (ADSS), Figure-8 Aerial Cables, and Aerial Lashed Cables.

Self-Supporting Aerial Cables (ADSS) are designed to support their own weight and withstand environmental stresses without the need for additional support structures. They are made entirely of dielectric materials, which means they don't conduct electricity and can be installed in close proximity to power lines. These cables are commonly used in power distribution and transmission environments.

Figure-8 Aerial Cables have a unique design that includes a built-in steel or dielectric messenger wire, which gives them a "figure-8" appearance. The messenger wire provides additional strength and support, making the cable more durable and easier to install. These cables are used in areas where additional support is needed, such as long spans between poles.

Aerial Lashed Cables are lashed to a separate support wire (usually a steel or other high-tensile wire) that is strung between poles. This method provides flexibility in terms of the types of cables that can be used and allows for easy maintenance and upgrades. These cables are often used in urban environments where cable maintenance and changes are frequent.

The main differences between these types are the support mechanism, material composition, and installation ease and flexibility. ADSS cables are self-supporting and made of dielectric materials, making them non-conductive and easier to install without the need for a separate messenger wire. Figure-8 cables have an integrated messenger wire for added support, making them slightly more complex to install but still relatively easy. Lashed cables require a separate support wire for lashing, making them more flexible for maintenance and upgrades but also more complex to install.
