A: Bandwidth: Optical fiber has been proven to have far wider bandwidth than any other media known to us such as wireless, copper wire, sonar, and even free-space-optics. Tera Hertz (10 to the 12th power) bit rate has been demonstrated in the lab by using the standard singlemode telecom fiber. A single strand of optical fiber can easily replace a large bundle of copper wires while boosting up system bandwidth. Loss: Optical fiber poses far lower loss to signal than any other transmission media. The typical loss per kilometer in a singlemode fiber is around 0.4 dB making it possible to send signal over a much longer distance (>100 kilometer) without the need for repeaters. Products & Services
Fiber optic rotary joints (FORJ) are the optical equivalent of electrical slip rings. They allow uninterrupted transmission of an optical signal while rotating along the fiber axis.
Specialty optical fiber is modified, usually by doping, for a specialized function. It consists of one or more transparent fibers enclosed in a protective covering.
Fiber optic couplers are optical devices that connect three or more fiber ends, dividing one input between two or more outputs, or combining two or more inputs into one output.
Fiber optic polarizers (FOP) are placed inline to improve the extinction characteristics of fiber optic cable. They allow the transmission of only one polarization, blocking light in unwanted polarization states.
Fiber optic switches route an optical signal without electro-optical and opto-electrical conversions.
