Coir into yarn using a simple one-handed system or a spinning wheel. Researchers at CSIR's National Institute for Interdisciplinary Science and Technology in Thiruvananthapuram have developed a biological process for the extraction of coir fibre from coconut husk without polluting the environment. The technology uses enzymes to separate the fibres by converting and solubilizing plant compounds to curb the pollution of waters caused by retting of husks. Because coir pith is high in sodium and potassium, it is treated before use as a growth medium for plants or fungi by soaking in a calcium buffering solution; most coir sold for growing
Fibre to the office start of the 1980s when fibre based connectivity was extensively explored. FTTO appeared as a response to the growing network complexity. The aim was to meet the following requirements: FTTO is a hybrid network involving fibre optic cabling (pre-terminated or extractable cables) and copper twisted pair patch cords with 8P8C connectors. In an FTTO environment, fibre is laid up vertically from the central distribution switch right to the office floor, where it runs horizontally to active FTTO switches at the users' workplaces. The final distance of 3–5 m to the end user desk is bridged using standard 8P8C twisted pair
