Cabling Design & Installation
The following sections show more about cabling infrastructure elements, and how they can be used for your communications cabling objectives.
Voice, Data, Cabling Services – Network cabling carries the lifeblood of your organization – information. To minimize expensive data network problems, Morse Communications Infrastructure Solutions follow strict installation and testing guidelines.
Coax Cabling Services – A critical piece of the infrastructure puzzle for our customers. Coax has been the medium of choice for high fidelity audio, television, satellite and broadband communications.
Twisted Pair Cabling Services – Unshielded Twisted Pair has been designed for use in voice applications and local area networks. Because of the relatively low cost this cable is widely used and is available in several different performance categories.
Fiber Optic Cabling Services – We install, terminate and test multi-mode and single-mode fiber (Inside and Outside). We’ve kept abreast of advances in the manufacture, termination and testing standards of fiber optic cable.
Server Room Installation Services – Because the server room is the centralized brain of your structured cabling system, we take special care to design and install it according to the highest standards.
Voice, Data Cabling Services
Today, your network cabling system carries the lifeblood of your organization – information. The installation, material, quality of cable and testing procedures are all much more critical in data wiring than in voice. The main reason for this is that networks today are designed to carry large amounts of information at incredible speeds. To accomplish this over unshielded twisted pair cable (UTP), many different criteria must be met.
Who sets the criteria and standards for network cabling? Well, the three major players are The Institute of Electrical and Electronics Engineers (IEEE – commonly called I-triple-E) who work on developing new protocols, the American National Standards Institute (ANSI), and the Telecommunications Industry Association / Electronic Industry Alliance (TIA/EIA) who issue the standards and testing procedures.
With bandwidth increasing and reliance on the network at an all-time high, getting information to where it needs to be is becoming more challenging than ever. Cabling problems, which account for over 50% of network problems, cost companies millions annually. Cable must be installed following strict and specific guidelines and the testing must be done using the right equipment calibrated for the latest standards
Coax Cabling Services
Coaxial cable is used primarily in Video, Audio and Security for video surveillance
Coaxial cables carry a nominal impedance of between 35 and 185 ohms. The three most common coax cables are 50 ohms (most widely used in thin-net Ethernet), 75 ohms (the cable your most likely using at home for your TV or cable modem) and 93 ohms, which is rarely used.
Coax cable can support much higher bandwidths than unshielded twisted pair (UTP) cable. The most efficient transfer of energy, over coax, occurs when all parts of the system have the same impedance.
The most common type of coax, called Flexible Coax, is a flexible cable, which uses a braided shield of extremely fine wires. This braid helps to make the coax flexible, but at a cost: energy or RF (radio frequency) signals leak through the small gaps in the braid. To combat this attenuation (energy loss), manufacturers have added several layers of braid and placed thin foil between the layers. This provides better coverage for greater shielding effectiveness. We normally use a quad shield (two layers of braid, two of foil) for 75-ohm applications.
Even though coax makes up a small percentage of our total installations, it is still a critical piece of the infrastructure puzzle for our customers. Coax has been the medium of choice for high fidelity audio, television, satellite and broadband communications.
Twisted Pair Cabling Services
Unshielded Twisted Pair
Unshielded Twisted Pair (UTP) has been designed for use in voice applications and local area networks. Because of the comparatively low cost this cable is widely used and is available in several different performance categories (Categories 3, 4, 5 and 6). Over 99% of our copper installations are UTP versus shielded twisted pair (STP), which is rarely used.
Electromagnetic interference is present in all types of cabling to some degree. There are two basic types of electromagnetic interference (EMI) that cable engineers worry about-electromagnetic emissions and electromagnetic immunity. Emissions refer to energy that is radiated by the cable, and immunity is the ability of the cable to reject outside signals. In local area networks (LANs), failure to properly manage EMI can have an adverse effect on the integrity of the signal being transmitted.
In an unshielded cable, careful design of the cable and the associated electronic equipment results in a “balance” of the currents in the two conductors of a pair. That is, the currents in the two conductors are equal in magnitude but flowing in opposite directions. Proper installation and termination of the cable is also critical to maintaining this balance.
In a balanced system, there is very little radiation of EMI since the external field from one conductor is effectively canceled by the external field from the other conductor of the pair.
Generally, the more twists per foot of cable, the better the cable is electrically balanced. Category 5 cable has more twists per foot than Category 3 or 4 cables and, therefore, offers better protection from EMI problems.
Fiber Optic Cabling Services
Fiber Optic cabling provides high bandwidth and is typically used for backbone connections between localized networking equipment and is increasingly becoming the preferred choice for high quality and reliable analog and digital communications. Although its higher cost can be prohibitive for desktop applications, fiber optic cabling provides a high security link, with immunity from electromagnetic interference (EMI). It is also the solution for inter-building links and other connections beyond the maximum 90m for Category 5e copper cabling.
Fiber Optic Cable Design & Installation
Slappey Communications, Inc. designs, installs, test, and maintains Fiber Optic systems. We perform Fusion Splicing & Termination of multimode & single mode fiber cables, including repair work. Our fiber technicians are skilled with external and internal fiber cable installs and repairs.
Fiber Optic Termination & Testing
Our Fiber Optic termination and testing service is offered to corporate end users as well as other communication providers who prefer to use our skilled services rather than invest in expensive test equipment and costly engineer training. Both methods of termination are offered either direct termination or fusion splicing of pre-manufactured pigtail assemblies.
Fiber Optic Advantages
Fiber optic system have very high bandwidth, with data rates up to 10Gb/s and the ability to aggregate multiple fiber connections for an even higher data rate.
Due to the low attenuation (or signal loss) exhibited by optical fibers, signals can be transmitted very long distances. Repeated systems can span as much as 10,000 to 15,000km, where optical amplifiers are used to boost the signal levels typically around every 80km or so.
Lightweight and Compact
An optical fiber is extremely light and therefore it is ideal for use in applications where weight is critical. Equally, a coated optical fiber is only 250 microns (a quarter of a millimeter) in diameter; a 12 core (12 fiber) cable may be less than 8mm in diameter for indoor use.
Fiber Optic Cabling Is Safe & Secure
Operational fibers do not radiate any signal, the optical signal is completely contained in the middle of the fiber. This means that fibers are frequently used for applications where data security is important such as military and government communications. A fiber optic communications cable does not need to carry any electrical current. It is possible to construct completely non-metallic cables so that full electrical isolation can be achieved.
Fiber Optic Cabling Is Future-Proof
Any fiber optic system currently installed will only be using a very small fraction of the potential information carrying capacity of the fiber. Therefore, as demand for communications capacity increases the system can be upgraded by attaching more sophisticated transmission equipment.
