Cable Ties – Not as Simple as You Think

cable tiesIn cabling system, both fibers or coppers are required cable management. Except the necessary rack, frame or panel, cable ties are also a necessary part of cable management. When we think of cable ties, the first impression may be the little plastic strips with self-locking, maybe with different colors. Many people do not care whether they choose a right cable tie or not, because they think that all the cable ties are the same as long as meeting the tying cable requirements. Are they pretty much the same? Actually, cable ties are not as simple as you think. From materials and size to construction and temperature rating, cable ties can have a wide range of features which allow them to be specialized to different situations. Today, Fiberstore Blog would like to bring you to know much about it.

Cable ties have to be able to meet the most varied demands these days as they are used in the widest range of operations – from the simple bundling of cables with cable ties to the absolutely specific use of cable ties under extreme conditions. Thus, many factors are taken into consideration during the design of cable ties.

Construction

Cable ties can be classified as either one-piece or two-piece construction. One-piece cable ties typically have a plastic locking device molded into the head of the tie. The locking device ratchets the notched strap to tighten and lock. This design has a lower cost of manufacturing and is used for general-purpose applications around home or office. Compared to one-piece cable ties, two-piece cable ties are with higher performance. They consist of a stainless-steel locking device embedded into the head of the tie, and a smooth locking strap. This design offers high tensile strength, and resistance to mechanical and environmental stress for applications that require greater performance than what a general-purpose cable tie offers. In addition, the smooth, infinitely adjustable strap also allows for the exact bundled tightness. The head of the two-piece cable tie engages the strap when installed, and permanently locks in place. With a lower profile and smoother cross-section, the uniform cross-section distributes stress across the strap more evenly than with one-piece cable ties. Thus, the two-piece cable ties are more resistant to brittleness and breakage in harsh environments, particularly appropriate for harsh conditions, such as ultraviolet exposure, extreme temperature, and exposure to moisture or chemicals, as well as for applications where retrofitting is not an option.

Material

The material design of different cable ties also needs to consider for different application, such as occurring indoors or outdoors; the environment’s temperature range; the presence of moisture, chemicals and radiation; flammability issues; and cost. Cable ties are available in a wide range of materials, each with its own specific properties. Among them, the most common type is Nylon cable ties. Nylon ties can offer good resistance to weather and ultraviolet rays in lower-temperature environments. In addition, for applications in harsher environments that require extra durability in the face of heat, chemicals and other corrosive elements, there are stainless-steel cable ties.

Special Features

Though the standard-design cable ties can meet most of our requirements, sometimes, we still need something special for special applications. For instance, most cable ties lock permanently, but sometimes, we would prefer to looking for a cable-tying solution that can be undone without actual cutting. Then, releasable cable ties have been launched in the market. In a releasable cable tie, the built-in locking tab can actually be disengaged, allowing the tail end of the tie to be pulled free from the head. Releasable cable ties tend to cost a little more than the standard type, but they save money and are more eco-friendly in the long run because you can reuse them over and over, as opposed to just throwing them away. Additionally, for different special applications, there are mounted head cable ties, marker ties, etc.

Color

The most commonly used cable ties are white and black. But colorful cable ties are also popular with users. These cable ties with rainbow colors are very useful when you are trying to color-code your cables, or just want to match the ties to your equipment. Moreover, you can use different cable ties to mark different cables bunch which is convenient for cable management.

Size

When using cable ties, you should also consider the size and shape. First, be sure to measure the diameter of the cable bundle you’ll be tying and decide the length. In general, to buy cable ties with a little longer length is better. Because no one will want to find out at the last minute that the cable ties are too short to use. In addition to length, width or shape are also important considerations to choose optimal cable ties for your cable bunch.

We may see that some users use random ties to tie cables. It is a non-standard practice in cabling. Cable ties, though, are only used to tie cables, they’re not as simple as you think. A right cable ties can help you reduce many issues during the cabling and maintenance. In a word, the benefits of cable ties cannot be underestimated once you choose a right cable ties.

Fiber Optical Faceplate Wiki

A fiber optic face plate is a coherent multi-fiber plate, which acts as a zero-depth window, transferring an image pixel by pixel (fiber to fiber) from one face of the plate to the other. Fiber optic faceplates can be applied in FTTH access network, telecommunication networks, CATV networks, data communication networks, which is used to bring fiber to the desk and can be widely used in multi-floor and high buildings. The fiber optic faceplate can be sometime called fiber wall jacks which are available with LC. SC, ST, FC fiber optic adapters, the port number is usually 2, 3 or 4 ports.

Generally, fiber optic wall plates can be divided into three types which is bevel fiber optic plate, hybrid fiber faceplate, FTTH fiber faceplate:

The bevel fiber wall plate is with 45 adapter plug- in/out angle, Hybrid fiber optic faceplate means the fiber adapter types are different from each other which can be SC-ST, SC-ST-LC, or
SC/ST/FC/LC, each adapter style is for one port.

Common Features of bevel fiber wall plate and hybrid fiber optic faceplate includes:
Size is 86*86mm
ABS plastic material
No additional insertion loss, simple operation, low construction intensity
The snap-in module is easy to install with straight tip style fiber optic connector
All fiber adapters are “universal” to support either multimode or single mode fiber connectors

Application:
FTTH access network
Telecommunication Networks
CATV Networks
Data communications networks

Except these two types, there is also another type which is the FTTH fiber optic faceplate, which is mainly designed for applications of FTTH, FTTB, FTTC, telecommunication networks and CATV4,Local area network. Check out some features of these FTTH fiber optic faceplate.
Indoor or outdoor rated
Available in 1×4, 1×8, 1×16 splitter as well as 2×4, 2×8, 2×16 splitter
Max. Up 16pcs of FTTH drop cable or pigtails
Suitable for wall-mounting or pole mounting application

Fiber wall plate is also used to create a fiber optic network at home. Besides the switches between different floor, fiber wall plate/jack and the pre-terminated fibers are needed. Look at the specs for the optical port on the switch. If the optical port is a pluggable device, you need to get its P/N and look up the spec. Most of the fiber sold on FiberStore that is conecterized, is patch chords. Fiber patch cord has very little strain relief in them. So take care when you pull them in your new installation that you do not damage them.

Fiber Optic Cleaver Needed In Fiber Optic Cleaving

If you have never done cable splicing and are just beginning to build your fiber optic link, it is recommended to start out with our fiber splicing kit, which is a great starting point for your fiber installation.

Optical fiber fusion splicing always requires that the fiber tips have a smooth end face that is perpendicular to the fiber axis. The cleave quality is very important in determining the fusion splicing loss. This is especially true for specialty fibers such as erbium-doped fibers and dispersion-compensating fibers.

Fiber optic cleaving is the process to scribe and break an optical fiber endface. Fiber optic technicians need some training in order to gain the skills necessary for best possible results.

The goal of fiber cleaving is to produce a mirror like fiber endface for fiber splicing – either fusion splicing or mechanical fiber splicing. Incorrect or pool cleaving techniques will result in lips and hackles which makes good fiber splicing impossible. A bad cleaving usually has to be redone.

The tools needed for fiber cleaving are called fiber optic cleaver or fiber cleave tools. There are two types available on the market: high precision fiber cleaver and field fiber cleaver.

The design of fiber optic cleavers varies among manufacturers such as AFL, Corning, Fujikura or York. But the working principle is the same. Here I describe a typical work flow of optical fiber cleavers.

Step One: Strip the fiber to its cladding size, the standard optical fiber cladding size is 125um. The strip length depends on your application.

Step Two: Clean the fiber with lint-free wipes moistened with isopropyl alcohol.

Step Three: Place the stripped and cleaned bare fiber into the fiber cleaver

Step Four: Scribe the bare fiber with either a cutting wheel or a blade

Step Five: Break the fiber with the built-in mechanism on the cleaver

Step Six: Remove the fiber scrap and put it into a fiber disposal unit

This semi-automated process produces high quality cleaving in minimum steps. It has been used widely in the fiber optic communication industry.

FiberStore provides a complete line of cables, connectors, termination tools, and test equipments for installing and testing fiber optic network. It’s important to make sure you have the proper set of fiber optic tools to working with your fiber optics. At FiberStore, they carry a wide selection of fiber tools, just about every tool needed to successfully install, terminate and test the fiber you’ve installed. Some of the essential fiber tools to have would be a fiber tester, fiber stripper, telephone line tester, fiber optic cleaver, tool kits and other tools.

What It Meaning by Cabling Management and Data Security Protection

When doing data cabling, it is necessary to make sure that all of the cables to be installed in its intended destination without damaging it or its data-carring capabilities. Most networking suppliers including fibre optic cable manufacturers provides many different cabling products protect cable. Cable management tools helps you cable plant looks good, and help you find the cables faster. There are three categories: physical protection, electrical protection and fire protection.

Physical protection

Cable can be fragile, easily cut, stretched and broken. Cable should be protected in ways of conduit, cable strays, standoffs and D-rings.

Conduit is the simplest form of cable protection which can a metal or plastic conduit to protect the cable as it travels through walls and ceilings. Conduit is a thin-walled plastic or metal pipe which is used in many commercial installations to contain electrical wires. When conduit is put in place, the individual cables are run inside it.

Cable trays is needed when the cable must be supported every 48” or 60” handing horizontally. It is installed in ceilings to prevents the cable from sagging and putting stress on the conductors inside. The horizontal cable from the telecommunications rooms that run to the individual telecommunications outlets are usually placed into this tray to support them as they run horizontally.

When terminating UTP wires for telephone applications in a telecommunications room, you will often see telephone wires run from a multipair cable to the 66-punch-down block. To be neat, the
individual conductors are run around the outside of the board that the punch-down blocks are mounted to (as show in Figure 13.11). To prevent damage to the individual conductors, they are bent around devices know as standoffs.

After the cables come out of the cable tray and enter the telecommunications room to be terminated, special metal rings called D-rings are needed to keep the individual cables in bundles and keep them close to the track. D-rings are also used on punch-down boards on the wall to manage cables, much in the same way stanoffs are. It is put in pace to support the individual cables, and the cable are run to the individual punch-down block on the wall.

Electrical protection

In addition to physical protection, electrical protection is also important during the designing and installing you cabling system. Electricity powers the network, switches, hubs, PCs and computer servers. Variations in power can cause problems ranging from having to reboot after a short loss of service to damaged equipment and data. A number of products-including surge protectors, standby power suppliers, uninterruptible power suppliers. And line conditioners are used to protect sensitive systems from the dangers of lighting strikes, uneven power, and accidental power disconnection.

Fire Protection

A few cabling-design concerns to prevent fire, smoke, or heat from damaging your cabling system, the premises on which they are installed and any occupants. Make sure you specify the proper flame rating for the cable according to the location in which it will be installed. The European market is demanding that cables used in LANs, WANs, etc. Meet LSZH specification. The IEC 60332-1 governs the Flame Retardant Grade specifications in reference to LSZH cables.
Another concern is the puncturing of fire barriers. In most residential and commercial buildings, firewalls are built specifically to stop the spread of a fiber within a building. Whenever there is an opening in a floor or ceiling that could possibly conduct fire, the opening is walled over with fire-related drywall to make a firewall that will prevent the spread of fire. In commercial buildings, cinder-block walls are often erected as firewalls between rooms.

After the proper cable management job done, data and cabling security protection is needed if your cable carry is sensitive and should not be view by just anyone. You may need to take extra steps when designing and installing your cabling system to ensure that the data stays when it belongs: Two ways to prevent data from being intercepted are EM (electromagnetic) transmission regulation and tapping prevention.

EM signal interception is the process of prevent the magnetic signals and turn them back into electrical signals that can be sent to another unwanted location. Susceptibility to EM signal
interception can be minimized by using shielded cables or by encasing all cabling runs from source to destination in a grounded metal conduit. These shielding methods reduce the amount of stray EM signals.

Tapping is the interception of LAN EM signals through listening devices placed around the cable. Some stapping devices are invasive and will actually puncture the outer jacket of a cable, or the insulation of individual wires, and touch the metal inner conductor to intercept all signals sent along that conductor. To prevent taps, the best course of action is to install the cables in metal conduit or to use interlocked armored cables. If it is practical. Grounding of the metal conduit will provide protection from both EM and invasive taps but not from taps at the cross connection.
