water‚ while the monohydrate forms when citric acid is crystallized from cold water. The monohydrate can be converted to the anhydrous form by heating above 78 °C. Citric acid also dissolves in absolute (anhydrous) ethanol (76 parts of citric acid per 100 parts of ethanol) at 15 °C. In chemical structure‚ citric acid shares the properties of other carboxylic acids. When heated above 175 °C‚ it decomposes through the loss of carbon dioxide and water. Citric acid is a slightly stronger acid than typical

The ITU-T G.984 Gigabit-capable Passive Optical Networks (GPON) standard represented an increase‚ compared to BPON‚ in both the total bandwidth and bandwidth efficiency through the use of larger‚ variable-length packets. Again‚ the standards permit several choices of bit rate‚ but the industry has converged on 2.488 gigabits per second (Gbit/s)
