By the mid-1990s, most network switch manufacturers had included aggregation capability as a proprietary extension to increase bandwidth between their switches. Each manufacturer developed its own method, which led to compatibility problems. The working group took up a study group to create an interoperable standard (i.e. encompassing the physical and data-link layers both) in a November 1997 meeting. The group quickly agreed to include an automatic configuration feature whic.
Polarization-maintaining optical fiber (PMF) is a single-mode optical fiber specifically engineered with high intrinsic birefringence to preserve the linear polarization state of an input light signal aligned with one of its principal axes, enabling stable propagation over long.
