How to test the cold joints at both ends of a fiber optic cable
Once both ends are terminated the fiber can be tested. Fiber testing used to involve a bulky OTDR (Optical Time Domain Reflectometer) operated by a geek with a degree in optical physics, but these days a simple hand held light source and power meter can be used. These test procedures assess the physical and functional qualities of fiber optic cables, connectors, and the network as a whole. As the components like fiber, connectors, splices, LED or laser sources, detectors and receivers are being developed, testing confirms their performance specifications and helps. Continuity testing verifies that the fiber is intact and that light can pass through from one end to the other without any blockages. Always inspect before you connect.

Price of OPGW optical cable vibration damper in Suriname
GL FIBER vibration dampers are designed for efficient transfer and dissipation of energy over a wide spectrum of frequencies. They feature all aluminum clamp construction to match expansion/contraction of conductor and break-away bolts for easy installation and proper torque. Overhead power lines are affected by wind, ice, low temperature and other meteorological conditions, causing the lines to vibrate and dance. The vibration frequency is high but the amplitude is small. Vibration dampers work to cancel damaging fatigue caused by wind-induced vibration. Most tuned damping devices operate best near their natural. IEC describes the Stockbridge damper as a system consisting of a messenger cable with two masses at its ends and a clamp that supports them; this clamp is attached to the conductor or earthwire with the purpose of reduction of the aeolian vibration on the conductor.
