What is optical cable positioning
Optical fiber alignment involves positioning two or more optical components (e. , fibers, lasers, photodetectors) with sub-micron accuracy to maximize light coupling efficiency. Even a 1-µm misalignment can cause >50% signal loss due to mode field diameter mismatches or angular. In fiber optics, data travels from the Tx port of one device to the Rx port of another, forming a two-way communication path. Where reels are supplied with protective material fitted over the cable, the protection should remain in place until the cable will be installed. Most optical networks have many optical couplings and even minor (< 1%) losses at these couplings accumulate to produce significant signal loss and consequent problems in data transmission.
