Coir fully ripened coconuts is thick, strong and has high abrasion resistance. It is typically used in mats, brushes and sacking. Mature brown coir fibres contain more lignin and less cellulose than fibres such as flax and cotton, so are stronger but less flexible. White coir fibres harvested from coconuts before they are ripe are white or light brown in color and are smoother and finer, but also weaker. They are generally spun to make yarn used in mats or rope. The coir fibre is relatively waterproof, and is one of the few natural fibres resistant to damage by saltwater. Fresh
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
