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 automation devices (including lights control, electricity meters, cooling and HVAC units), and other devices with network interfaces may be connected to the backbone network with Gigabit speeds. FTTO should not be confused with fibre to the desk (FTTD), which is a concept for structured cabling that is found mostly in military environments as a secure communication technology. Due to the signal transfer qualities of fibre and its electromagnetic interference (EMI) resilience, signals can be transferred over distances longer than 100 m (100 m is the channel limit in traditional structured cabling networks). Multi-mode fibre cabling covers distances of up to
