Coir the known carpet firms of Treloar and Sons in Ludgate Hill, England, for the manufacture of coir into various fabrics suitable for floor coverings. Coir fibres are found between the hard, internal shell and the outer coat of a coconut. The individual fibre cells are narrow and hollow, with thick walls made of cellulose. They are pale when immature, but later become hardened and yellowed as a layer of lignin is deposited on their walls. Each cell is about long and in diameter. Fibres are typically long. The two varieties of coir are brown and white. Brown coir harvested from
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
