Preparation for Qualified FTTH Network Installation. During the equipment installation of FTTH network, contamination is the greatest problem which should be noticed in the optical networks.

Preparation for Qualified FTTH Network Installation

Along the link distance, a single particle mated into the core of a fiber can cause optical insertion loss, return loss (ORL), and equipment damage. So visual inspection is required to determine if fiber optic connectors are clean before mating them. This tutorial will tell about inspection and cleaning issues for FTTH network deployment before equipment installation. Fiber Connector Inspection The inner-most zones of connectors are more likely to be contaminated that outer zones. Use the microscope to inspect connector endface.If it’s not clean, use cleaning tools to clean the optics.Make sure there is no contamination on the endface and connect fiber interfaces.

Optical Fiber Interface Inspection Optical fiber interface inspection includes two situations. Cleaning Methods There are dry and damp cleaning methods. Typical Acceptance Values Conclusion. FS.COM Introduced LC Uniboot Fiber Patch Cables.
