La fibre la plus couramment employée dans le domaine des télécommunications demeure la fibre monomode G652.B & G652.D (standard UIT-T repris par la CEI 60793). Grâce à son faible affaiblissement linéique et à sa bande passante, elle permet la réalisation de liaisons longue distance à très hauts débits. Ces fibres sont préconisées dans les réseaux […]

ADSS cables. All-Dielectric Self Supporting cables. The All-Dielectric Self Supporting (ADSS) cable is a completely non-metallic structure in which the tensile load bearing elements are integral within the circular design of the cable – usually in the form of aramid yarns or stranded glass reinfroced plastic rods. The structure of ADSS Cable Typically a loose […]

Worldwide, technologies for broadband access networks are advancing rapidly. Among these, the technology applying single mode fiber provides for a high-capacity transmission medium which can meet the growing demand for broadband services. The experience with the installation and operation of single mode fiber and cable based networks is huge, and ITU-T Recommendation G.652 describing its characteristics […]

In General, fiber coating consists of primary coating, secondary or buffer coating, fiber identification, removability of coating. 1 Primary coating Silica fiber itself has an intrinsically high strength, however surface flaws reduce its strength. A primary coating must therefore be applied immediately after drawing the fiber to size. The optical fiber should be proof-tested. In […]

Before any detailed discussion on how to handle optical fiber cable, some brief discussion of fiber and cable design is required. Eliminating confusion between the different terms, and providing an understanding of the cable construction will make handling the products less complicated. Fiber The cable cross-section in figure 1 demonstrates a two fiber cable for interconnect applications. […]

Sharks are not the nemesis of the Internet, says the International Cable Protection Committee (ICPC), which has released an analysis of the main causes of submarine cable breaks. Essentially, sharks and other fish were responsible for less than one per cent of all cable faults up to 2006. Since then, no such cable faults have […]

Since the late 1980s, fiber-optic networks have steadily become the bedrock for the ever-expanding global telecommunications system. Early fiber-optic links, such as the eighth transatlantic telecommunications cable (TAT-8) installed in 1988, were relatively simple systems by today’s standards and used on-off signaling to transmit a few hundred megabits per second (Mbit/s) over a single optical […]
