The types of connectors with fiber optic cable

The transmission of signals by light waves is related to the wavelength of the light.Some wavelength s travel through optical fiber more efficiently than others.Light wavelength needs to be measured in nanometers.Visible light, in the range of 400-700nm, does not travel through fiber optic cable with enough efficiency for data transmission.Optical communications occur at three ideal wavelengths or windows:850nm,1300nm,1550nm.High-speed transmissions typically use the 1300-nm window.

To be detected legibly, an optical signal transmission must have enough power when it reaches the receiver.Attenuation, or power loss, is the amount of signal that is lost as it travels through the communications medium from the source to the receiving node.Attenuation in fiber optic cable is measured decibels.Loss of optical power is directly related to the length of the cable along with the number of and radius of bends in the cable.Power loss also occurs as the wave passes through connectors and splices.

The wave must carry a minimum level of power when it leaves the transmitting device in order to be accurately translated at the receiving end.Tasmanian power level is called the power budget.Power budge for optical fiber cable communications is the difference between the transmitted power and the resulting signal strength, or sensitivity, at the receiver as measured in decibels.It is the smallest transmitter power and receiver sensitivity needed for a signal to be sent and received fully intact.For high-speed communications, the power budget must be 11 dB.

Fiber Patch Cable comes in two modes: single mode and multimode. Single mode fiber optic cable is used mainly for long-distance communications, has a central core diameter of 8-10 microns, and has a 15-micro diameter cladding.The inner core diameter is much smaller than that of multimode cable.Only one light wave is transmitted on the cable at a given time.

Laser light is the communications signal for LC-LC Single Mode Patch Cord .The laser light source, contained in the sender's transmitting interface, coupled with a relatively large bandwidth, enables long distance transmissions of up to 43 miles at high speeds.Singapore fiber optic cable does not have a determined speed limitation.

Multimode Fiber Cable can support simultaneous transmission of multiple light waves for broadband communications.The diameter of multimode LC-SC Patch Cord is between 50 and 115 microns.The transmission distance potential is not as great as that for single mode cable only up to 1.24 miles or 2 kilometers-because the available bandwidth is smaller and the light source is Waker.The transmission source for multimode cable is a LED device that is in the sending node's network interface.

The types of connectors most often used with fiber optic cable are subscriber connector and straight tip. both of these connector meet EIA/TIA-568 standards ,Generally ,SC connectors can be used with eigher single mode fiber optic cable lalthough they can be used for multimode.Physically ,SC connector have a square shape and use a push -on-to- lock connection.ST connectors have a round shape and use a bayonet type lokcing attachment,similar to a BNC connector.The lucent Connector(LC To LC Fiber Patch Cable),developed by LC cucent Technologies,is another frequently used connector that looks similar to an sc connector in that LC connector has a sqare shape and uses a push on to lock connection.LC connectors have the advantage that they are about half the size of regular connectors,which is a space-saving feature,often making it easier to add more calbe runs in the future,Another type of connectors,Mechanical Transfer Registered Jack is a newer connecor that has grown in popularity and has a square type end.
