Fiber Optic Cables offer large bandwidth, very high security, and immunity to electrical interference. Fiber Optic Cables are offered in different lengths, and you can choose either riser or plenum cable. Riser cable is good for running cables in walls. Plenum cabling is approved by the NEC® for installation in air spaces or ceilings because it does not emit toxic fumes when it burns. You can run Fiber Optic Cable to the desktop for a planned deployment of high-data-rate systems such as FDDI, multimedia, or ATM (Asynchronous Transfer Mode), or applications that require large file transfers. It can also address environmental problems such as EMI (electromagnetic interference) or high security requirements. Ceramic connectors on the Ceramic-Terminated Cables make the highest quality cables and provide low signal loss, high reliability, and long life. Composite connectors are good quality and are constructed of a durable polymer and also offer high precision and low light loss. All of these cables are ideal for use as work-area, cross-connect, or equipment jumper cables.
