The procedures in this document describe basic inspection techniques and processes of cleaning for fiber optic cables, bulkheads, and adapters used in fiber optic connections. Note: This document is intended for use by service personnel, field service technicians, and. There are three main principles that needs to be taken in consideration for an efficient optical connection: a perfect core alignment, perfect physical contact and dirt-free connectors. It is important that every fiber connector be inspected and cleaned prior to mating. That advice is misguided. It could hurt an installer or get them sued by an irate network owner. This guide outlines best practices for maintaining and inspecting installed fiber optic infrastructure, enabling network owners to keep their systems running at peak efficiency. Fiber optics infrastructure consists of optical fiber cables, connectors, splice enclosures, distribution panels, and. Small oil micro-deposits and dust particles on fiber optic cable optical surfaces may cause a loss of light or degraded signal power which may ultimately cause intermittent problems in the optical connection. Fiber optic testing and maintenance protocols not only maintain the reliability of the network, but also allow for early detection of potential failures and optimization of performance.
