Descriptions
This system utilizes a tube bundle contains one or more sub-tubes and extremely light weighted mini-cable units that can installed at any time. The main advantage of this technology is the cheap tube, which can be conveniently installed in direct buried mini-tube, may contain one or more 2~48 fiber mini-cable(s). Each mini-cable can be installed by blowing to the sub-tube. This technology can help us to save a lot of costs since you can install fibers at any time without preparing for unexpected increasing needs. At the same time, the carriers will benefit from quickly capacity increasing without paying for outdate loss caused by installing new ducts and cables.
Mini-cables are available with steel tube type and all dielectric type. Steel tube type utilizes a stainless wire tube filled with gel and 245µm optical fibers, and then sheathed by high density polyethylene.
All dielectric type utilizes an all dielectric tube filled with gel and 245µm optical fibers, and then surrounded by aramid yarns with sheathed by high density polyethylene.
