The Usability Of Various Network Patch Cables

The Usability Of Various Network Patch Cables

A common network patch cable consists of eight wires with four twisted pairs. In the each side, the cable feature RJ45 connectors, for instance the Enhanced Category5 (CAT5e) patch cable. It’s accustomed to develop connection with or between network devices and applications. This particular Ethernet cable is mainly used for connecting computers with devices such as routers, hubs or switches.

However, so far as the utility of a CAT5e patch cable is concerned, it is chiefly used in Ethernet connection where one should join a host of the computing devices for enhanced connectivity. In fact, this cable supports connection on some sophisticated telecommunication platforms for example ATM. High-speed data transmission is its USP also it meets the cabling requirements of most from the Ethernet environments.

One of the key reasons for the usability of this enhanced version of the CAT5 cable is it has a fair run length 100 meter that is enough for cabling in a small and medium-size Ethernet environment. Though within the recent years, CAT6 and CAT6e patch cable has been designed to offer run period of 550 meters and 1000 meters respectively, these products aren’t compatible with most of the network devices a sophisticated network uses. These are vendor-specific and also you need install just those hardware and software products which are fine with them. This unsuitability of latest category cables has occasioned such wide utilization of CAT5e patch cable which is universally accepted.

Moreover, CAT5e patch cables are available in both unshielded twisted pair (UTP) and shielded twisted pair (STP) configurations. Though it holds true the UTP patch cables are comparatively more frequent, certain specific network applications demand the STP because the later is greatly useful in preventing transmission disturbances brought on by Electro-Magnetic Interference (EMI).

Network patch cables can be found in the stranded and solid variety too. Within the former, the primary cable consists of a cluster of thin cables in a metallic jacket, while the eight wires inside the cover are solid copper wires within the later. However, both in of these categories, the wires are coupled to create four pairs. Despite the fact that each of them offer seamless link with Internet, the stranded cable includes a greater degree of usability because of its interference and noise-canceling capability. The stranded variety is preferred to the solid category also since it involves lesser amount of risk in the process of unplugging.

Crossover cable also operates as Ethernet patch cable and may connect two PCs together. While such an array of network patch cables is available in the marketplace, you have to consult a network engineer to know which will suit your Ethernet network the most.

However, apart from the common four-pair patch cable, engineers may also opt for a fiber optic patch cable. Though the utility of CAT5e network cable has never been questioned, fiber patch cables are extensively used too. This variety of patch cable is made of fiber optic material and also the connectors at the two different ends are also available in the fiber optic.

Beneficial Properties Of Fiber Patch Cables

Beneficial Properties Of Fiber Patch Cables

Nowadays fiber optic patch cable has started to experience an important role in completing the end-to-end connection of systems. It is used immensely for a number of purposes associated with data transmission. One of the most common uses is perfect for the change in internet signals in the source router till the computer. As a kind of beneficial network cables, fiber patch cables are very popular and used in almost all kinds of digital data transmissions.

Why are fiber patch cables beneficial? To begin with, let’s make it clear what makes the optical fiber communication important. The fiber optics makes sure that certain desired properties associated with a communication are satisfied. And also the quality they maintain regarding these properties makes using these network cables desirable.

Interestingly, the fiber optic patch cables require being compatible with each one of these properties to keep up with the network quality. So the attributes desirable of the fiber cables are also good for the patches. A few of the important properties are listed below.

  • Bandwith Rate: Data of high volume may be easily transferred using the optic cables. In fact, with the mainline network cables, one can transfer terabytes of information every second as completed in case from the worldwide Internet exchange data. The same can probably be said about the fiber optic patch cables. The bandwidth of those cables is extremely high.
  • Communication Speed: The physical communication happens over modulated waves of light. Consequently, the rate of communication is extremely fast with the fiber optic networks. One can use these networks to access real time data around the world. The patch cables are compatible with the speed plus they can transfer data at the same speed as the main network cable.
  • Attenuation Absence: Attenuation of signal is really a critical factor in most of the networks. However, to have an optical network, this is practically absent. The data can traverse along the network without any amplifier installed in the path. The patch cables also do not attenuate the information.
  • Transferred Data Accuracy: The transfer of data takes place with a high degree of accuracy. The information is affected with practically no external hindrance. No signal coming form outside really changes anything about the data. As a result, the information transfer preserves the precision of information exchange. The fiber optic patch cables maintain high levels of accuracy with regards to bandwith.
  • Security Factors: Fiber optic patch cables are as secure as the overall optical fiber network. They’re extremely hard to break into and therefore the potential of data leaking out of the network is virtually minimal.

The suggestions above properties result in the optical patch cords beneficial when it comes to real life application. Make sure that you have the best patch cable with the proper length and aperture, and you are in a position to enjoy the advantages of a safe and secure and high speed communication.

Comparison between Factory Termination and Field Termination

Comparison between Factory Termination and Field Termination

Fiber optic cable termination can be mainly split into two types that are factory termination and field termination. For tighter loss budget, the best approach is factory terminated cables since it is much easier to achieve low loss and quality connector terminations in a controlled factory environment. On the other hand, field terminations provide far more flexibility in meeting system requirements. As technicians face important trade-offs in deciding which method of choose, here provides a detailed comparison on merits and choices backward and forward types.

Merits Of Factory Termination And Field Termination

Advantages:

  • Factory Termination: The factory has to guarantee the quality. Fiber optic manufacturers have highly trained technicians and quality equipment for the job. Factory technicians usually are expert on fiber connector polishing plus they produce thousands of optical patch cords and fiber pigtails on a daily basis. Factory termination offers the cheapest. Since factories produce mass volume of fiber patch cords, they’ve reduced the price towards the most favorable point. This is actually the most economic choice.
  • Field Termination: Field termination offers the best flexibility in meeting system requirements. You can just pull the fiber cables and terminate them later. That you can do on-the-spot repairs wherever there’s a defective fiber link. This is actually the biggest advantage of doing the termination yourself.

Disadvantages:

  • Factory Termination: Factory termination doesn’t provide as much flexibility as field termination. You need to get the exact listing of fiber lengths and quantities and you’ve got to make certain that you’ve enough spare period of cable for every termination.
  • Field Termination: Field termination is high cost. You need some polishing tools and supplies. Field termination quality are Suitable for multimode applications, however for single mode applications, you’d better leave that to factory termination. The field termination technician must be highly skilled. He would have to practice a great deal offline before doing the actual work. A poor termination can cost you both time and money.

Choices Of Factory Termination And Field Termination

Choosing Factory Termination:

  • Factory pre-terminated cables: For this kind of business, you give a list of cable types, lengths and quantities to the factory. The factory will deliver each pre-terminated cable on the reel. You just need to pull these cables through duct carefully having a cable netting to safeguard the connectors.
  • Factory pre-terminated pigtails and splicing: This can be a intermediate approach. You order cable segments with factory-mounted connectors on one end only. You have to order some fiber pigtails and then splice the pigtail towards the unterminated end from the cable. This is a fast and simple approach. However, it takes that you curently have the fusion splicers. Or else you would need to choose the less reliable mechanical splicing.

Choosing Field Termination:

  • Field installation of epoxy and polish connectors: Plenty of experience technicians still prefer this way because it provides the best flexibility and the lowest possible cost. Epoxy and polish connectors overlap with used by factories. You pull the fiber first, after which terminate the fiber on the site. This involves fiber optic epoxy, high temperature curing oven, scribe tools, polishing films and fiber optic inspection microscopes. This method needs you have a fiber termination kit which includes these items.
  • Field installation of quick termination connectors: Quick termination connectors really are a god bless for emergency repairs. This kind of connector functions as an optical pigtail. It is pre-polished within the factory. It features a fiber stub within the connector body. You just need to cleave your fiber, insert it into the connector body, and lock it per the connector manufacturer’s instruction. However, it doesn’t provide just as much long-term reliability as the epoxy and polish connectors. Also, quick termination connectors are much more costly then standard epoxy and polish connectors.
Fiber Jumpers Inspection And Cleaning Methods

Fiber Jumpers Inspection And Cleaning Methods

Optical patch cords used as jumper cables, also called fiber optic jumpers, are often used between the optical transceiver and fiber terminal box. The main purpose of fiber optic jumpers detection is to ensure the quality of system connection, reduce the failure factors, and identify the fiber point of failure in the event of a failure. There are many detection methods which are mainly divided into artificial simple measurement and precision instruments measurement.

  • Artificial┬áSimple Measurement: This method is generally used to rapidly detect the fiber jumpers’ ON/OFF and distinguish fiber jumpers in construction. It uses a simple light source to infiltrate visible light into the fiber optic jumper from one end, and observe which one glows from the other side to achieve the detection. Although this method is simple, it can not quantitatively measure the attenuation and breakpoint of fiber optic jumpers.
  • Precision Instruments Measurement: Using the optical power meter or optical time domain reflectometer (OTDR) to quantitatively measure the fiber jumpers, the attenuation of fiber jumpers andconnectors can be measured, even the breakpoint position of fiber optic jumpers can be measured. This method can be used to quantitatively analyze the reasons of fiber optic networks’ failure and evaluate optical networking products.

Fiber optic jumper is mainly used in the engine room to realize the connections between the fiber terminal and the devices, the equipment and devices, and the ports of wiring closet. It is very commonly used in fiber optic networks. We found that in network maintenance, to make a good connection between fiber optic jumpers and fiber couplers (adapters), the fiber jumpers end face’s cleanliness is an important factor, which directly affects the quality of network communications.

Fiber Jumper end face means the distal section of its two connectors. It is often an easily overlooked place, because of nonstandard operation, which can easily be contaminated. In the daily operation and maintenance to the light path, operating specifications should be strictly enforced to ensure the cleanliness of fiber jumpers face. If the fiber end face is polluted, we must follow standardized procedures for cleaning. Here are how to inspect fiber end face’s cleanliness and the clean-up methods.

  • Visual Inspection: Under normal circumstances the most common practice is to check the face dirt: Disconnect the device pick up the fiber jumpers against the light, by observing the side facing the bright light refraction to detect whether the end is clean and smooth. Through observation, if the end face of a smooth bright light reflection is considered relatively clean, if the side face of the light is reflected light and not too smooth, it is likely there is dirt or scratches end face of such face will seriously affect the quality of the optical transmission. Of course, with the end surface inspection apparatus can be more fully understand the details of the end surface.
  • Instrument Checks: Currently fiber end face inspection tools for instrument more, which optical fiber microscope is the most widely used professional inspection equipment. Under normal circumstances for multimode fiber-optic microscope display magnification of 200 times, while for single-mode fiber-optic microscope display magnification of 400 times. More advanced fiber-optic microscope magnification can not only switch between the two, but also through the LCD screen displays the fiber end, and thereby not disconnect the device detects the fiber end, but also to avoid the risk of eye injury by laser.

Cleaning Methods
In the fiber jumper end face inspection process, once the optical fiber end surface microscopy revealed the presence of fiber dirt, it must be properly cleaned to avoid triggering a decline in the quality of the communication problems. Each method has its own maintenance staff to do cleaning and maintenance, different cleaning methods to get different cleaning effect, if conditions permit, or the help of professional cleaning tools to help better. The importance of clean face a lot of companies now have noticed, and develop a variety of face cleaning tools, the author will introduce the following tools to assist in a professional and non-professional tools assisted two end cleaning methods.

In the absence of tools to assist in the case need to prepare ethanol, clean cotton balls, lens paper. Cleaning procedure is as follows.

  • 1) Clean cotton ball in one hand, and then ethanol drops on cotton balls, alcohol should not drop too much.
  • 2) With an anhydrous alcohol with a cotton wipe face along the same direction, the number of dirt under the end of the product.
  • 3) Put a good face with an alcohol wipe three or more layers of the folded lens paper to wipe face in the same direction until the alcohol is completely dry and the end face of the light reflection of bright reflective so far.
  • 4) Carefully examine each end to reflect the circumstances and phototabdus whether the fiber end face of residual debris and, if necessary, repeat the above steps 1-3 until the end clean flawless so far.

In the cleaning process should use the right cleaning tools and cleaning steps if incorrect cleaning methods not only face clean ineffective, but also may cause permanent damage to the face. After cleaning, be sure to check again and then insert the connector end to ensure that contaminants have been completely removed. If necessary, you will need to be cleaned again again, in order to ensure complete removal of the first failed to clear the dirt, so that the end to keep clean.

The above talking about fiber jumpers end face inspection and cleaning methods are simple and feasible, but in the usual course of operation and maintenance we should enhance the awareness of this aspect’s cleaning. Because dust and oil will damage the fiber coupling, when the fiber jumpers are not in use, we must use protective sleeve to protecte the fiber optic connector, as well as to fiber couplers. Every time before the use of fiber jumpers we should clean the end face using a fiber paper. With cleaning consciousness, we can effectively reduce the fiber jumpers failures, and improve the quality of fiber optic lines and maintenance efficiency.
