  • Fabrication of Arched Bridge Structures

    Fabrication of Arched Bridge Structures

    Today, there are two primary methods used in the construction of arch bridges: the Cast-in-Situ Free Cantilever Method and the Slip-Formed Sections Method. Each technique has its advantages and applications depending on the terrain and design requirements. VSL specializes in the design, prefabrication, and construction of precast arch bridge structures providing tailored solutions that reduce environmental impact. Arch structures are unique structural forms which resists forces majorly by converting them to compressive forces, in a process popularly referred to as arch action. Curved reinforced concrete segments are cast offsite, at Shay Murtagh's modern factory.

  • Fiber Optic Communication SDH System Technology

    Fiber Optic Communication SDH System Technology

    Synchronous Optical Networking (SONET) and Synchronous Digital Hierarchy (SDH) are standardized protocols that transfer multiple over using or highly light from (LEDs). At low, data can also be transferred via an electrical interface. The method was developed to replace the (PDH) system for trans.


  • Armored Logging Fiber Optic Cable Technology

    Armored Logging Fiber Optic Cable Technology

    Designed for long-term downhole monitoring applications; features include corrosion resistance, pressure resistance, and excellent cost-performance; conductors consist of bare copper wire or optical fiber. 8mm Fiber Optic Double Steel Wire Armored Logging Cable is specially designed for oil. Complete armored fiber optic cable guide covering cable construction, armor types (steel tape/steel wire/aramid), installation methods (direct burial/duct/aerial), and outdoor/industrial selection recommendations. Armored fiber optic cables provide enhanced protection for fiber strands in demanding. An armoured fiber cable is a reinforced optical cable designed with a protective metallic or non-metallic layer around the optical fibers. This armor shields the delicate glass fibers from physical damage such as rodent bites, crushing, moisture, and abrasion. With a durable protective layer, they are ideal for harsh or high-traffic environments.
