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 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
