Your Range of Subsea Tether and ROV Tether Choices 

​

Twisted Pair Tether

Twisted pair tethers are a simple yet effective technology. They're made by interweaving two wires, which are used to send signals back and forth between a remote-controlled underwater vehicle, or ROV, and the surface above. This type of tether is commonly used in areas with shallow water because these locations often only need shorter lengths of tether.

​

The design of twisted pair tethers makes them both uncomplicated and reliable. One of the main reasons they're so popular is because they're not overly expensive to make. Additionally, they are usually more resistant to problems like signal loss or interference when compared to some other tether types.

​

However, it's also important to recognize their limitations. Twisted pair tethers don't offer a lot of bandwidth, which means they can't handle the transmission of larger data types. For instance, if you want to send high-definition video data, these tethers might not be the best choice because they just don't have the capacity for it. So, if you have larger data needs, you may need to look into using other types of tethers.

​

Fiber Optic Tether

As an alternative to the twisted pair technology, fiber optic tethers introduce a different mode of signal transmission. These tethers utilize an array of either glass or plastic fibers to carry the signals between the remotely operated underwater vehicle, known as an ROV, and the water's surface. As opposed to their twisted pair counterparts, fiber optic tethers are primarily employed in deep-sea explorations, where the required tether lengths tend to be considerably more extensive.

​

One of the most striking advantages associated with fiber optic tethers is their remarkable bandwidth capabilities. This feature facilitates the conveyance of larger data streams, such as high-definition video and various forms of sensor data, which would typically overwhelm the bandwidth capacity of a twisted pair tether. Furthermore, fiber optic tethers offer a commendable level of resistance to potential signal loss or any form of interference, a trait that augments their reliability, especially in harsh environmental conditions.

​

Despite these beneficial characteristics, it's worth noting that fiber optic tethers come with their own set of challenges. These tethers are notably more costly to produce than other tether types. Additionally, they necessitate the use of specialized equipment, both for their installation and for their ongoing maintenance. Therefore, it is crucial to handle these fiber optic tethers with care, given their higher investment cost and the specialized handling they require.
