UTP stands for "unshielded twisted pair." It is a cable type with one or more pairs of twisted insulated copper conductors contained in a single sheath. UTP cables are the most common type of cabling used in desktop communications applications.
Cat5e is defined by TIA/EIA-568-B-2, it is an enhanced version of Cat5 with additional specification for far end crosstalk. Testing requirement is up to 100Mhz and a maximum working distance is 100M.
Cat5e is commonly used for 100Mb/s network, 100BASE-TX Ethernet and it is suitable for Gigabit Ethernet, 100Base-T.
Cat6 standard is designed for Gigabit Ethernet and is backward compatible with Cat5e. The general difference between Cat5e and Cat6 is on performance abd bandwidth. Cat6 standard requires better insertion loss, return loss, NEXT and ELFEXT.Cat6 standard also push bandwidth from 100 Mhz for Cat5e to 250Mhz.
10Base-T, 100Base-TX, 100Base-T4, Token Ring, 100VGanyLAN, TP-PMD, ATM-UTP
The gauge of our raw cable is 24 AWG.
STP stands for shielded twisted pair. STP cable requires metal shield over each individual pair to protect cable from external EMI.
CAT6 is a cabling standard with 10GBase-T in mind. CAT6 is a standard for Gigabit Ethernet and many other network protocols. CAT6 is backward compatible with CAT5/5e for 10Base-T, 100Base-T, 1000Base-T and it is expected to suit the 10GBASE-T standard.
FTP stands for foiled twisted pair. FTP cable requires metal foil over entire group of copper pairs as shielding. This is the most common type of shielding on network and computer cable.
A local or long-distance telephone communication.
Fiber optic cable is a wave guide. Light travels in multimode fiber in multiple modes. Typical core/cladding sizes are 62.5/125µm and 50/125µm.
Light travel in singlemode fiber in one mode. Typical core/cladding size is 8.3~9.5/125µm
For multimode fiber, the operating wavelengths are 850nm and 1300nm. For singlemode fiber, the operating wavelengths are 1310nm and 1550nm.
Data Rate (Mbps)
|10Base-FL||850nm||Multimode 62.5/125 or 50/125||10||2km|
|1000Base-LX||1310nm||Multimode 62.5/125 or 50/125||1000||550m|
Multimode 62.5/125 fiber is still the most common fiber for data but Multimode 50/125 are getting more and more popular due to additional bandwidth and distance.
Ceramic sleeve offer higher precision, it’s more costly and it’s recommended for singlemode application. Fiber adapter with ceramic sleeve is good for both singlemode and multimode applications.
Metal sleeve is more durable compare to ceramic but the precision is not as high as ceramic and it’s recommended for multimode application. Is not recommended to apply metal sleeve adapters for singlemode application.
Cablesys promises .2dB or less on Insertion Loss. The standard fiber is .75dB. Most Industries have .5dB Insertion Loss.
Insertion Loss is the total optical power loss caused by the insertion of a component such as a connector in an optical fiber system.
Return loss is the measure of power reflected from imperfections in an electrical or optical communications link. The return loss is expressed with dB.
PC, UPC and APC are the three different types of end surface polish for singlemode fiber cable assemblies. Cablesys offers 55dB or better on return loss for all singlemode assemblies. Most suppliers in the Industry offer PC polish with 45dB singlemode assemblies. APC offers 65dB RL which is a special requirement that must specify separately for the requirement.
It is always best to refer back to the cable manufacturer spec for bend radius information.
In general, it is recommended to maintain 10x of outer cable diameter on bend radius for fiber cable with no pull load. For fiber cable subject to tensile load, it's recommended to maintain 15x of outer cale diameter on bend radius.
Optical Fiber Nonconductive Riser (OFNR) this type of cable contains only class fiber and no copper conductive elements.
It is usually used for vertical runs between floors.Optical Fiber Nonconductive Plenum (OFNP) contains glass and no copper conductive elements also but its purpose is usually for horizontal runs especially within an air handling conduit.
WIRING AND CONNECTORS
Cabling standard defines one pair of conductors as transmit pair and one pair of conductors for receive pair. When terminal devices are connected to a switch or hub, the cross over is done internally within the switch or hub, the cross over are done internally without a hub or switch, a crossover cable must be used.
10BaseT and 1000BaseTX crossover only require crossing of Pin 1/2 with Pin 3/6. For Gigabit crossover, T4 crossover is required. In addition of crossing Pin 1/2 with Pin 3/6, Pin 4/5 must cross with Pin 7/8. T4 crossover is backward compatible for 10BaseT and 1000BaseTX crossover.
RJ45 Connector or RJ45 plug is used commonly to refer to any 8P8C modular plug.
10BASE-T is the IEEE standard that defines the requirement for sending information at 10 Mbps on unshielded twisted-pair cabling, and defines various aspects of running Ethernet on this cabling.
100BASE-T is the IEEE standard that defines the requirement for sending information at 100 Mbps on unshielded twisted-pair cabling, and defines various aspects of running baseband Ethernet on this cabling.
1000BASE-T is the IEEE standard that defines the requirement for sending information at 1000 Mbps on unshielded twisted-pair cabling, and defines various aspects of running baseband Ethernet on this cabling.

Use table below for LED indicator functions:
|TP ACT||Green||Blinks||If fiber-optic is not present for converter self-diagnose / detecting|
|If both ports link with any TP packets transmitting|
|OFF||Fiber-optic link is present|
|OFF||With no TP/FX LINK on, i.e. only turn on the power and the ACT don not blink at all, please consult your local dealer|
|TP Link||Green||ON||TP connection is good|
|FX ACT||Green||Blinks||When any FX packets transmitting|
|FX Link||Green||ON||When fiber connection is good|
|FDX*||Green||ON||When full-duplex mode is detected in TP port|
|PWR||Green||ON||When +5VDC power detected|
RJ-45/STP, UTP Cat 5, straight-through cable is accepted. Cabling from TP port to a TP device is shown as below:
To Workstation: DIP switch on DTE
To Hub/Switch: DIP switch on MPR
The twisted pair port supports duplex mode selection by Auto-Negotiation (A-N). The following is the duplex mode parameters:
|Fast Ethernet Device:||Duplex Mode Support:|
|Fast Ethernet Hub||Half-Duplex|
|Fast Ethernet Switches (without A-N)||Half-Duplex|
|Fast Ethernet Devices*
Normally an A-N switch will be detected and set to Full-duplex where a dual-speed hubs will be detected and set to Half-Duplex.

RoHS was adopted by the European Union in February 2003 as the Directive on the Restriction of the Use of Certain Hazadous Substances in Electrical and Electronic Equipment 2002/95/EC or commonly known as the Restriction of Hazadous Substances Directive. RoHS took effect on July 1st, 2006 and it become lw for EU countries to restrict the use of six hazadous materials in electronic and electrical equipent manufacturing. The six substances restrict by RoHS are Lead, Mercury, Cadmium, Hexaval Chromium, Polybrominated Biphenyls and Polybrominated Diphenyl Ether.
