  • Low-temperature resistant AWG wavelength division multiplexer for rail transit

    Low-temperature resistant AWG wavelength division multiplexer for rail transit

    It operates at 50GHz or 100GHz channel spacing ITU Grid DWDM wavelengths from 1526nm to 1565nm. The AAWG DWDM can be used to replace the filter-type DWDM Mux DeMux for cases where no power is available. The low cost and high performance make it the ideal solution for metro and. We produce fiber-coupled Wavelength-Division Multiplexing (WDM) devices that combine (Mux) or separate (DeMux) multiple wavelength channels into or from a single optical fiber. Two types are available: integrated arrayed waveguide gratings (AWG), offering low cost, compact size, and precise ITU. HighEasy Coarse wavelength division multiplexer (CWDM Mux/Demux) utilizes thin film coating technology and proprietary design of non-flux metal bonding micro optics packaging. NEL is the pioneer and market leader of Athermal AWG.

  • Inspection of Civil Engineering Works for Communication Tower Foundations

    Inspection of Civil Engineering Works for Communication Tower Foundations

    The inspection process involves a detailed assessment of tower structures, foundations, anchoring systems, ladders, platforms, fall protection systems, antennas, cables, and grounding arrangements. Communication Tower Inspection is a critical safety and compliance activity that ensures the structural integrity, operational reliability, and regulatory compliance of telecom towers used for mobile, radio, and data transmission. These towers are exposed to harsh environmental conditions, heavy. Conduct thorough inspections of telecommunication towers with this structured checklist. Cover tower elevations and height, structural members and base anchors, foundations and guy anchors, guy wires and fittings with tension measurement, antennas and microwave dishes, transmission lines, paint and. A communication tower foundation design is the structural blueprint that determines the anchor point of the tower on the ground. Evaluating the ground allows for checks in soil erosion or any recent changes in the terrain, which may affect the longevity of the foundation over time. We inspect for cracks in welds, and loose, missing or short bolts.
