The following is a list of optical testing tools used for FTTx (Fiber to the x) network: 1. VFL (visual fault locator) is capable continuity check fiber link up to 15km, break/bend visual identifier for fibre along patch panel/hub areas, It is mainly applied in fibre link construction and troubleshooting at locations where fibres are accessible. […]
An optical time-domain reflectometer (OTDR) is an optoelectronic instrument used to characterize an optical fiber. An OTDR is the optical equivalent of an electronic time domain reflectometer. It injects a series of optical pulses into the fiber under test and extracts, from the same end of the fiber, light that is scattered (Rayleigh backscatter) or […]
Fusion vs. Mechanical Splicing Unfortunately, damage to fiber optic connectors is common in FTTA installations. If a fiber connector is damaged, either a whole new cable can be pulled or the damaged connector can be replaced. Fusion splicing is one method for attaching a pre-terminated fiber connector with a fiber stub (called a pigtail) to the broken […]
