How to Properly Perform a Mid-sheath Entry on a Microfiber Cable

A microcable is designed to be as light as possible so it can be deployed using forced air. That means the microfiber’s sheath needs to be lightweight as well. There has been some discussion on what is the proper way to enter the microfiber for a mid-sheath entry. In this blog, Chris Gemme explains its importance and shows the proper way to perform this task in a simple how-to video.

The blown microfiber cable evolution has grown in the U.S. broadband market. Like the name implies, a blown microfiber cable is a miniaturized version of a stranded loose tube cable placed in a microduct using high pressure air to assist with its installation.

Not only is the size of the microcable reduced to make the cable as light as possible for the air-blown application, but it uses a unique jacket design that is a significant departure from traditional optical fiber cables. Specifically, the jacket on microcable is more like a skin rather than the thick protective sheath found on traditional cables. That level of protection for the microcable is not necessary, as it gains its protection in the microduct.

Entry into a microfiber cable is still a craft sensitive job. It is much simpler and easier than with traditional cables; however, there are some who are not performing it properly. On some recent visits, I demonstrated the proper way to perform this task.

Because I receive so many queries on how to properly enter the microfiber for a mid-sheath entry, I created this short how-to video for you. I welcome your feedback and questions in the comment section below.
