What Is Unshielded-Twisted-Pair (UTP) Cable

:: What is UTP Cable? UTP stands for Unshielded Twisted Pair cable. UTP cable is a 100 ohm copper cable that consists of 2 to 1800 unshielded twisted pairs surrounded by an outer jacket. They have no metallic shield. This makes the cable small in diameter but unprotected against electrical interference. The twist helps to improve its immunity to electrical noise and EMI. (You can get Cat 5e and Cat 6 UTP Patch Cable from us) For horizontal cables, the number of pairs is typically 4 pair as shown below. For backbone cables, the number of pairs will typically be

Laser Diode Characteristics

Buy Fiber Optic Light Source from us. Laser Diodes (LD) are very commonly used in fiber optic communication systems and their characteristics are of primary importance. So here we give a summary of LD’s characteristics. Laser Diode Threshold The above figure shows a laser diode’s output optical power versus injected electrical current  – P/I Curve. As we can see, the output optical power varies as a function of the current passing through the diode. When biased below a threshold current Ith, the output power is very low. But as the current increases over the threshold Ith, the output optical power

Communication Systems–Voice, Data, Video, LAN, HVAC, Fire Alarm, Security, and CCTV

Today’s businesses reply on their communication systems to stay competitive. Communication systems cover a wide range of voice, information processing, and signaling systems used to connect users together or to share information. Five categories of communications systems in commercial buildings need structured cabling systems. These are: Phone systems Data systems Local Area Networks (LANs) Building Automation and Control Systems (BACS) Sound Systems Each type of system is defined by NEC (National Electrical Code) in different sections of the NEC. Each system requires its own cabling system and usually is bid and built by separate contractors. Phone Systems Most commercial businesses

What is BER (Bit Error Ratio) and BERT (Bit Error Ratio Tester)?

:: BER (Bit Error Ratio) Is a Signal Quality Quantitative Measurement of Digital Communication Systems Transmission quality of telecommunication systems can be assessed directly by measuring how well the output signal reproduces the input. Bit Error Ratio (or Rate) is the signal quality concept used for digital communication systems (Signal-to-Noise Ratio SNR is used for analog communication systems instead). BER measurements compare digital input and output signals to assess what fraction of the bits are received incorrectly. It is defined as where is the number of bits received in error over time t, and is the total number of bits

How to Use Corning RST-000 Ribbon Fiber Splitting Tool

You will learn how to use Corning’s ribbon fiber splitting tool to divide fiber optic ribbons. Now let’s go! :: What the RST-000 Can Do Split a ribbon fiber up to a length of 0.5 meter (20 inches) per cleaning For longer lengths, just clean the splitting tool and repeat the process. Both mid-span and end-of-ribbon applications. Split ribbon with 4 to 36 fibers. As indicated by the sum of the stacked numbers on the tool (2+2 = 4 fibers, 12+24 = 36 fibers) The cleaning process’s purpose is to remove ribbon matrix material residues from the tool’s channels after
