Coir Coir Coir (), or coconut fibre, is a natural fibre extracted from the husk of coconut and used in products such as floor mats, doormats, brushes and mattresses. Coir is the fibrous material found between the hard, internal shell and the outer coat of a coconut. Other uses of brown coir (made from ripe coconut) are in upholstery padding, sacking and horticulture. White coir, harvested from unripe coconuts, is used for making finer brushes, string, rope and fishing nets. It has the advantage of not sinking, so can be used in long lengths on deep water without the added weight
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
