Fiber discing is a manual link that separates stable links from dangerous links. Completion of welding does not mean that the link is reliable. The diameter of the fiber coil is too small and the direction is chaotic. Macro-bend loss may lurk in the tray for several months before being exposed; if a corner of the label is missing, half of the computer room will need to be rummaged through for future maintenance.

The circle diameter is based on the unified bottom line, not on the feel.

It is recommended that the ring diameter of conventional G.652 single-mode fiber optic discs should be controlled to be above 60mm, that is, the radius should not be less than 30mm. The accommodation space for the ODF tray and splice box is generally designed with a radius of 40mm. Although the anti-bend optical fiber can be tightened, it is not recommended that different teams make it according to their own feel. The bottom line should be unified to facilitate handover and acceptance. Pigtails and bare fibers cannot be cross-laminated during coiling. The heat-shrinkable tubes should be placed sequentially along the side grooves of the tray, and the welding points should avoid the stress-bearing position of the coil body. After the tray cover is closed, there should be a gap of about 10mm between the fiber coil and the inside of the door panel.

Circle direction and fixation are important

• The winding direction of the entire circle remains consistent, and the stress is uniform during retraction and retraction;
• The starting point is first fixed with fiber clamps or flame-retardant tape, and then placed into position one by one;
• Check the remaining amount before closing the tray cover to avoid the cover from pressing the slimming body for a long time;
• The reserved length is recorded as 0.5 to 1m on each side of the joint. The excess length is put into this tray and does not borrow from the adjacent tray.

Write at least three things in the label

A fiber disk must at least be marked with the local port number, the opposite end device or location, and the fiber sequence direction; flag-shaped or wrapped labels can be used, and handwriting must be done with an oil-based pen. The port table will be updated on the same day when changes are made on the same day.
