Is it acceptable to offset the fiber optic splice
Quick answer: Industry acceptance threshold for a single fusion splice is 0. 1 dB should be. If instead you get them to 0. 02dB (a pretty good splice) each, it's only 0. 2dB for the splices - equivalent to just another km of cable. Figure 1: Primary loss factors in fiber splicing: (A) Mode Field Diameter mismatch, (B) Lateral core offset, and (C) Angular misalignment. Extrinsic Loss (Lateral Offset) 3. Extrinsic Loss (Angular Tilt) Understanding the Variables: w 1, w 2 Mode Field. Typical splice loss values (the measure of loss in optical power across the splice point) are usually lower for fusion splices (typically less than 0. Optical fiber splicing is a critical. Fiber transmission lines will frequently have more than 10 splices between terminal points; to estimate the overall line loss, we need a reliable figure for the splice loss to be expected under varying line conditions.

What is the part of the cable tray called
Several types of tray are used in different applications. A solid-bottom tray provides the maximum protection to cables, but requires cutting the tray or using fittings to enter or exit cables. A deep, solid enclosure for cables is called a cable channel or cable trough. A ventilated tray has openings in the bottom of the tray, allowing some air circulation around the cables, water drainage, and allowing some dust to fall through the tray. Small cables may exit the tray throug.
