Polishing is usually where a lot of the labor, skill, and time occurs. Pre-Polished Style ConnectorsĪ much easier and faster way to terminate a connector onto a fiber strand is using pre-polished connectors, so the installer does not have to polish the fiber connector. The downside to this method is that it takes a great skill level and a lot of time to do one fiber connector termination. This fiber connector termination method is very good because the fiber connectors are very inexpensive, plus it keeps and maintains a continuous strand of glass all through the connector. Polishing is commonly done by hand with a polishing puck or by a machine if done in a manufacturing setting in a “figure eight” pattern motion using polishing fiber lapping paper in several steps. After the epoxy cures, the connector tip goes through several rounds of polishing to complete the termination. After that, the exposed excess fiber is scribed off and placed in an oven to cure. Next, the installer threads the bare glass strand through the ceramic ferrule of the connector until it protrudes out of the tip. Then, the installer places some epoxy glue in the back of the connector. The installer first has to strip the fiber strand down to the bare glass. Installing epoxy-style connectors is a slow process and requires a high level of skill to make a good termination. This was the only way to install fiber connectors for many years. Epoxy-Style Connectorsįor a long time, terminating bulk fiber cable involved some type of epoxy-style connector. Users can choose the best termination method for their application. These three methods use “ Epoxy Style Connectors,” “ Pre-Polished Style Connectors,” or “ Fiber Optic Pigtails.” Each of these methods has several advantages as well as some disadvantages. Typically, there are three common ways to install and terminate a fiber connector on the end of a bulk fiber cable run. Several years ago this was true, but today it may not be the case, because there are some other ways to terminate bulk fiber. Many end users fear that installing fiber connectors on bulk fiber requires a high level of skill to be done correctly. But, for bulk fiber trunk runs, after the bulk cable is pulled, technicians need to install connectors before using the fiber cable. Not much end-user support is needed beyond “fiber end face cleaning,” which is good practice before using any fiber assembly. This fiber cable can range from several hundred fiber cable assemblies connecting equipment together within a data cabinet to large bundles of bulk fiber trunk cables running from the data center out to remote areas of the building or campus.įiber cable assemblies are typically available in a wide range of lengths with fiber connectors terminated, polished, and tested at the factory. Today, many data center installations use some form of fiber cabling. 3 Common Methods to Terminate Connectors on Fiber Cable
