Several common fiber optic connectors
<P>Several different types of connectors are available for fiber optic patch cables,such as LC,FC,and MTRJ,to name a few,However,the two most common types of fiber-optic connectors in use today are the ST-style and the SC-style connector ,Notice that the ST connector uses a barrel BNC-type adapter and the SC connector uses a block-style adapter,An easy way to reference these is the ST style connector is a stick-and-adapter,An easy way to reference these is the ST style connector is a stick and twist motion to connect the female connector over the male connector and twist to lock it in place and the SC connector is a stick and click motion to connect. LC LC fiber optic cables connect two components with fiber optic connectors , <A href="http://www.fiberstore.com/narrow/lc-lc_v1646t0/common-fiber-patch-cables_897"><STRONG>LC LC Fiber Patch Cord</STRONG></A> are used to send high-speed data transmissions throughout your network.</P><IMG alt="lc-sc fiber optic patch cable" src="http://www.fiberstore.com/imgCache/5/505009d4c810ca2af05f6a3e83868db4.image.550x550.jpg">
<P>Fiber-optic cable is either single mode or multimode.In addition to this classification,fiber-optic cable is also designated by how it is sheathed,the two main classifications of sheathing are loose tube and tight buffered.loose tube cable consists of many individual strands of fiber-optic cable encased in a protective sheath known as a buffer tube ,which contains a strong material that provides additional strength for the entire sheath,Most loose-tube fiber-optic cables are sheathed in 250-micron weather protective material that can with stand aerial as well as underground installation,Loose tube cabling is usually found in out door fiber -optic installations.</P>
<P>many fiber optic patch panels use SC style connectors,whereas a significant amount of modern telecommunications equipments utilizes SC style connectors,This does not pose a problem because fiber -optic patch cables are available with LC-SC connectors(<A href="http://www.fiberstore.com/narrow/lc-sc_v1648t0/common-fiber-patch-cables_897"><STRONG>LC-SC Patch cord</STRONG></A>),SC-SC connectors,and SC-ST connectors,Fiber-optic patch cables are available in many different lengths,it is a good rule of thumb to use the shortest cable possible to reduce the amount of slack in the cable,thus reducing the number of loops in the cable and reducing the possibility of violating the minimum loop rule..Fiber optic cabling is fairly new in comparison to copper media which has been in use for decades, fiber optic cable is make up of three main components:cord,cladding ,and protective coating ,extreme care must be taken during the manufacturing process to ensure that the highest-quality glass with the fewest impurities is created,</P><IMG style="HEIGHT: 218px; WIDTH: 222px" alt="lc lc fiber optic patch cable" src="http://www.fiberstore.com/imgCache/a/a583bd1d024158a41613193df71ec0b1.image.120x120.jpg" width=124 height=120>
<P>The protective coating can either be losse tube or tight buffered loose tube has many individual strands of cable sheathed together and tight buffered has a single strand in the protective sheath,fiber-optic cable has the ability to carry more data over longidistances than copper cable,making it suitable for many data and voice applications,fiber optic cable is more suitable for locations where a fire hazard exists,there is no chance of stray boltages causing sparks fiber opticcabling uses light waves called modes to transmit gignals from a transmitter to reciver,fiber optic cables is available in two main types:sigle mode andmultimode,single mode is more sutied for higher bandwidthy applications ,single mode is mor suitd for higher bandwdth applications over longer distances ,wheras multimode fiber -optic cable is more suited for shorter distances,</P>
<P>Single mode fiber optic cables(<A href="http://www.fiberstore.com/narrow/lc-lc_v1646t0/singlemode-fiber-cables_261"><STRONG>LC-LC Single Mode Patch Cord</STRONG></A> ) has a smaller diameter core;multiple fiber optic cabling ,attenuation are factors that degrade signal quality in fiber optic cabling,Attenuation is a law of physics regarding the behavior of light waves, there are variety of fiber optic connector types available,different telecommunications equipment manufactures make their equipment with different styles of connectors ,and fiber -optic patch cables are available to meet every requirement.</P>
