Coir water is used to process brown coir, while seawater and fresh water are both used in the production of white coir. It must not be confused with coir pith, or formerly cocopeat, which is the powdery material resulting from the processing of the coir fibre. Coir fibre is locally named 'coprah' in some countries, adding to confusion. Green coconuts, harvested after about six to 12 months on the palm, contain pliable white fibres. Brown fibre is obtained by harvesting fully mature coconuts when the nutritious layer surrounding the seed is ready to be processed into copra and desiccated coconut. The
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
