The few right angles saved on the routing diagram may be the error link that can not find the cause half a year later.The jumper was killed by the sticker wall around the side of the wire slot. It looked like it was unbroken, and the light signal was actually leaking.In this paper, the figures of the bending radius that should be guarded in different links are explained clearly, and

the means of inspection are given. Static

  • and dynamic two sets of numbers Ordinary OS2 jumper: The static bending radius is generally not less than 30mm, and the construction should be further relaxed
  • when moving. G.657 Bending-resistant tail: Usually bends to around 10mm without significant deterioration Lay the backbone cable along the bridge: not
  • less than 10 to 20 times the outer diameter of the cable Remaining length of the coil: The
  • radius of the coil is not less than 40mm, it is strictly prohibited to wrap your arms or tie them into

a small circle. Why did

Xiao Beng suffer? When the radius is below the threshold, the light exceeds the critical angle of total reflection at the corner, leaks from the core to the cladding, forming a macro bending loss, and the 1550nm window is more sensitive than the short wavelength.The occasional pressing and stepping of people and ties seems to be nothing. After experiencing temperature changes and vibration, the bending point often deterioratesinto a failure point. Single-mode single-corearmored jumper It is suitable for pedaling and squeezing risk segments, but armor is only resistant to external forces, which does not mean

that the radius requirement can be

exempted. I suspect it's overbent. How do I check it? First, find the acute angle and tie indentation with the naked eye along the line, and then compare the reading of the long wavelength window with the optical power meter: the single-point loss is abnormally high, and the OTDR cannot see obvious reflection events, so it is preferred to suspect the macro bend; after loosening the bend, repeat the test, and the reading canbe significantly reduced to locate the problem point.the actual fibre-covering practicesin the machine room and cabinet, Industrial Automation

and Machine Vision Networking Solutions There are special chapters to compare. Bending radius is a full-link short board game where any dead angle takes effect at a minimum.If you encounter a hard angle that cannot be circumvented, you would rather add a right-angle guide groove or use a more than one-meter jumper, and don't take the margin of the entire link to gamble; EB-LINK's armored rat-resistant jumper only measures the actual insertion damage and bending state one by one before leaving the factory, and you can dial 0755-83179002 to check the uncertain radius.
