Meeting the challenge of moving to the next generation of PON networks Evolutions, extensions, diversions are an integral part of the life of the network. Technological evolutions, which allow the increase of flows are also to be taken into consideration in the reflections of the life of the network, its [...]
There are two types of maintenance for optical networks: - Preventive maintenance, which consists of periodically inspecting the network in order to identify any problems and thus avoid breakdowns and service interruptions. - Corrective maintenance, which consists of repairing breakdowns when they occur. Indeed, some fiber cuts, such as "excavator blows", are difficult to avoid. Many times, preventive maintenance is seen as a cost and not as an investment that reduces downtime and increases customer satisfaction.
First reserved for OIV - Operators of Vital Importance - in the last century (France Telecom, SNCF, EDF, National Defense...) then for "big" operators at the time of telecom deregulation, optical networks have recently explosively deployed thanks to FTTH projects. France has taken a leading position in Europe with the France Very High Speed Plan launched ten years ago.
CREDO Circle wrote this note about FTTH & 5G Backhauling. Context: The deployment of 5G networks does not only implies the evolution of the radio access network (RAN). The impact on the backhaul and fronthaul will be high because new requirements emerge (bandwidth, latency, synchronization, etc.) Fibre-optic [...]

Recipe for optical networks - measurements of optical networks. This Measurements sheet completes the Acceptance sheet which presents the importance of controls at different levels, components, optics or documentation.
Acceptance of optical networks - excluding fiber performance measurements The finding: The construction of optical networks is a complex operation that involves many players: operators, design offices, installers, their subcontractors and communities. The infrastructures of these optical networks, from long-distance transport to the access network, land or air, must be durable and scalable to absorb the increase in speeds expected by customers and to accommodate new technologies to come on fiber (400G , XGS-PON, 5G, …).
The purpose of this application note is to provide technical and safety details on the choice and use of a visual fault locator (VFL – Visual Fault Locator) commonly called a “red light pen” used to test fiber continuity. monomode optics (also usable for multimode fibers). Today, [...]
