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 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
