Jetting Y-Block

The Y-Block is a specialized accessory designed for fiber installations, enabling the addition of a second and third fiber cable or duct into existing duct systems. It’s an essential tool for network upgrades and expansions, allowing new cables or ducts to be installed without disturbing the existing infrastructure.

Benefits of Using a Y-Block

Parallel installation of multiple cables or ducts: The Y-Block allows two or three cables or ducts to be inserted into the same system, enabling the installation of additional fiber cables or microducts while protecting the existing infrastructure.
Interchangeable connection: The connection to the fiber blowing machine is replaceable, offering flexibility for different setups and requirements.
Flexible connections: Equipped with adaptable clamps that fit a range of duct sizes, ensuring compatibility with various installations.
Compact design for tight spaces: The Y-Block is specifically designed to be compact, making it ideal for confined spaces such as small manholes and network nodes.
Easy handling: Lightweight and practical, the Y-Block is simple to install and manage in the field.

Additional Applications

Duct installation: The Y-Block can also be used to blow ducts (instead of cables) into existing duct systems. The process is similar to cable installation, with a smaller duct being blown into place instead of a cable.
