The correct polarity for fiber-optic cabling

Observing the correct polarity of fiber-optic cabling ensures that the transmitters (Tx) and receivers (Rx) in the optical transceivers on both sides of the transmission path are connected to one another. Various connection methods and standards relating to installation specifications and quality assurance are used to ensure that cabling systems operate using the correct polarity (such as, e.g., ISO/IEC 11801-1, EN 50174-1, EN50600-2-4).
