one of a group of cells that develop in the walls of the seminiferous tubules. Spermatogenic cells include spermatogonia, spermatocytes, and spermatidsâall of which are transitional forms between primary sexual cells and spermatozoa.
long-haul optics. Long-haul optics refers to the transmission of visible light signals over optical fiber cable for great distances, especially without or with minimal use of repeaters. Normally, repeaters are necessary at intervals in a length of fiber optic cable to keep the signal quality from deteriorating to the point of non-usability. In long-haul optical systems, the goal is to minimize the number of repeaters per unit distance, and ideally, to render repeaters unnecessary.
What is Fiber Optic Pigtail. fiber-optic-pigtails. Fiber optic pigtail is a fiber cable end with fiber optic connectors at only either side of the cable while leaving sleep issues no connectors, so the connector side could be from the equipment and the other part can be melted with optical cable fibers.he end of the pigtail is stripped and fusion spliced to a single fiber of a multi-fiber trunk. Splicing of pigtails to each fiber within the trunk breaks out the multi-fiber cable into its component fibers for connection to the end equipment. Fiber pigtails can have female or male connectors.
