Legendary fiber optic cable ship burns to a crisp on Skeleton Coast
309 days
France Telecom-Orange on Friday announced that an unexplained fire had erupted on its cable ship, the Chamarel, off the Skeleton Coast of Namibia in the Atlantic Ocean. after battling the blaze for several hours, the crew abandoned ship. the vessel was returning from a mission to repair the Sat3/WASC/Safe submarine cable which connects Portugal and Spain to nine West African countries, circles around the southern tip of Africa, and connects to India and Malaysia.
The entire crew of 56 escaped the Chamarel safely, and were recovered by a Namibian fishing vessel and returned to Walvis Bay, Namibia. no injuries were reported, but this is the second incident in a single month where a ship has caught fire in Namibian waters. On August first, a South African Tuna fishing boat caught fire and sank outside of Namibian port city Lüderitz.
The Chamarel, formerly known as CS Vercors, is actually a historically important vessel in international fiber optic communications. the ship was in service since 1975, and laid over a hundred thousand kilometers of cable, including AT&T’s TAT-6 transatlantic cable, and EMOS-1 the first Israeli-built undersea cable. In 2000, the vessel was used to set the record for the deepest submarine cable at 1,610 meters (just over one mile).
France Telecom-Orange currently operates six cable ships, four are dedicated to maintenance services in the Mediterranean basin, the Atlantic Ocean and the Indian Ocean, and two are used to lay new submarine cable.

What Fiber Optic Supplies Do You Need To Clean A Fiber Optic Connector?
314 days
First, let’s understand why a fiber optic connector needs cleaning.
You may never need to clean the RJ45 connector for your computer’s Ethernet network connection, then why do you need to clean a fiber optic connector if it serves the same purpose as a networking connection?
While, the answer lies in how optics work differently than electronics. In electronics, as long as you have a contact between two connectors, they work perfectly; or at least most of the time.
But for optics, light beams travel in straight lines, they bounce off whenever they hit anything and thus loss their energy.
So in order for a light beam to carry the information signal and travel thousands of miles of optical fiber, its path must be kept crystal clear, including fiber optic connectors in the network.
What part of a fiber optic connector should be cleaned, exactly?
OK. now comes the critical part. What part in the fiber connector needs cleaning, exactly? the short answer is the ferrule’s body and its end face. but what exactly is a ferrule?
Ferrule is a cylindrical and also the most critical part in an optical fiber connector. it is usually made from stainless steel or Zirconia.
Zirconia is a type of white colored ceramic which is an extremely refractory material. it offers chemical and corrosion inertness to temperatures well above the melting point of alumina. Zirconia is the preferred material for high quality fiber optic ferrules.
Ferrules have a tiny hole in the center which holds optical fiber in place. Then the fiber is scribed and precisely polished to flush with the end face of the ferrule.
Two fiber connectors can then mate to each other with a mating sleeve. when mated, two ferrules’ end faces contact each other perfectly and thus pass light from one fiber to another.
Ferrules get dirty from dust, stain and debris made by constant plugging and unplugging after having been used for a while. these contaminations will block the light path and thus seriously reduce the light power and may disable the network connection.
Is there only one method for fiber connector cleaning?
There are many different ways to clean a fiber optic connector. They are not exclusive but rather complementary to each other. when one method failed, you can always try another method. and that is why there are so many fiber optic supplies for cleaning fiber connectors available on the market.
1. Air spray. Air dusters are used to blow loose particles from optical fiber connector end face. Optic grade is more expensive. Air spray is a non-abrasive fiber optic cleaning method.
2. Lint-free wipes with isopropyl alcohol. the operator folds the lens paper (such as the lint free wipes) into 46 layers and lay it flat on a table. He then holds the connector vertically straight and cleans the end face in figure 8 motion.
3. Reel fiber optic connector cleaners. Connector reel cleaner is a dry cleaning method with a quick, reliable operation and uniform results. They use 2 micrometer weaved polyester cloth to clean optical fiber connectors. this is an abrasive fiber optic cleaning method but pad underneath cleaning cloth mitigates this significantly.
4. Stick or swab type cleaners. these specially built Cletop sticks come in 2.5mm and 1.25mm versions. They are designed for dry cleaning fiber optic connector mating sleeves, bulkhead adapters and receptacles.
5. In-situ cleaning. this semi-automated fiber optic cleaning method is specially designed for fiber optic connectors plugged in patch panels and hardware devices.
6. Pre-saturated or soaked wipes. Pre-saturated wipes are good for cleaning glass fiber or connector end faces. They are available in a convenient pre-saturated towelette. the towels are durable and non-linting. Pre-saturated wipes are a convenient option for field use.
Fiber Optics for Sale co. offers all types of fiber optic supplies for fiber optic cleaning.
What is a Fiber Optic Splice Closure?
316 days
Fiber optic splice closure is the equipment used to offer room for fusion splicing optical fibers. it also provides protection for fused fiber joint point and fiber cables. There are mainly two types of closures: vertical type and horizontal type. a large variety of fiber splice closures are designed for different applications, such as aerial, duct fiber cables and direct burial. Generally speaking, they are usually used in outdoor environment, even underwater.
:: Fiber Optic Splice Closure Types
For outside plant splice closure, there are two major types: horizontal type and vertical type.
Horizontal type splice closures look like flat or cylindrical case. They provide space and protection for optical cable splicing and joint. They can be mounted aerial, buried, or for underground applications. Horizontal types are used more often than vertical type (dome type) closures.
Most horizontal fiber closure can accommodate hundreds of fiber connections. They are designed to be waterproof and dust proof. They can be used in temperature ranging from -40C to 85C and can accommodate up to 106 kpa pressure. The cases are usually made of high tensile construction plastic.
Vertical type of fiber optic splice closures looks like a dome, thus they are also called dome types. They meet the same specification as the horizontal types. They are designed for buried applications.
Splice closures provide room for splicing outdoor fiber cables together. Fiber splice trays are needed too. They provide the perfect protection for outside plant fiber cable joints.
Fiber splice closures accept both ribbon and round fiber cables. each type (ribbon or round cable) fits respective requirement of different fiber splicing counts. They are widely used in optic telecommunication systems.
:: Fiber Optic Splice Closure Installation Steps
Here I will outline the main steps involved in fiber closure installation.
1. Components in the closure
Fiber optic splice closure kit usually includes: end plate, splice tray organizer, fiber splice tray, cover, cable grommets, grommet retainer, mounting bracket and misc. hardware.
2. Fiber Cable Sheath Preparation
2.1 Expose the rip cord. this step involves marking the location with a tape marker, ring-cutting the outer jacket with a sharp knife, removing the corrugated armor if applicable, and shaving off the outer jacket to expose the rip cord.
2.2 Remove the outer sheath. this step involves making a longitudinal slit down the outer sheath, peeling off the outer jacket and corrugated metal, and cutting the rip cord flush with the end of the corrugated metal.
2.3 Remove the inner jacket. this step involves using the rip cord under the inner jacket to slit it, cutting aramid yarns, cutting central strength member, and cleaning the filling compound.
3. Bonding and Grounding Hardware Installation
Bond clamp installation. this step involves sliding the cable clamp over sheath, sliding the bond shoe under the corrugated metal, placing the bond plate over the bond shoe and securing the sheath grip.
4. Assembly of Cables to Closure
The preferable location for the two main cables is in the lower end plate port. if a third or fourth cable is required, it is easier to install it in the upper end plate port as a branch cable. this fiber optic splice closure is designed for two cables in each of its two ports. if only one cable will be installed in a port, the provided rubber grommet plug is used to substitute for the second cable.
4.1 Install Cables to end Plate. this step involves unscrewing knob and removing grommet retainer, positioning the end plate assembly, attaching the sheath grip to dielectric cables, sliding cables and sheath grip through, and securing sheath grip to backbone.
4.2 Grommet Installation and External Grounding. this step involves applying B-sealant, pushing the grommets into the end plate port, and applying more B-Sealant.
4.3 Fiber Unit Preparation and Distribution Organizer Installation. this step involves removing more loose tubes, separating each cable’s loose tube into two groups, positioning the distribution organizer, securing the loose tubes to the distribution organizer, and securing the loose tubes.
4.4 Splice Tray Installation. this step involves placing the splice tray, fastening the end of the splice tray to the organizer, and installing cables, grommets and external ground.
4.5 Optical Fiber Splicing. this step involves splicing holder placing, fiber splicing and fastening the splice holder lid.
5. Fiber Optic Splice Closure Cover Installation
The Future of Fiber Optics
324 days
Fiber optic technology is nothing new, but new applications of this technology are likely to change the way we live and work. for several decades fiber optic technology, transmitting light via flexible fibers of very thin glass or other transparent materials, has been available. however the cost of this technology was considered too expensive for anything other than long-distance applications such as telecommunications. The significant benefits over traditional copper wiring were what made the additional cost worthwhile.
Today, higher volumes of production have created lower costs so that they are now feasible for many applications. The capacity of fiber optics have also expanded dramatically with cables, once limited to one wavelength, now capable of carrying well over one hundred wavelengths at once.
The result of these and other technological advances is higher bandwidth and the accessibility of more applications.
U-verse and FiOS systems from AT&T (NYSE: T) and Verizon have recently put fiber optics in the limelight. These systems are for delivery of TV and Internet respectively. AT&T’s cable TV system utilizes fiber to central nodes then devolves to copper cabling to each home or business. Verizon’s system uses a different strategy, bringing fiber optic cable all the way into each home or business. A similar system has been in place in Japan for some time.
Other industries are working with lasers for a wide variety of applications. The ability of lasers to provide very high power makes them a good option for many industrial needs including welding. Non-laser fiber optics are replacing copper in automobiles as a lighter weigh option for use in CD players, GPS systems, seat and climate controls and air conditioning systems, and in the field of research they have allowed the creation of super accurate clocks. These super clocks combine optical fiber with a laser to allow the measurement of time more accurately for ultra precise scientific applications.
Key to the performance of fiber optic cables is the polishing. The power of these cables is in the ability of light to move super fast along the length of the cable, however each end of the optic fiber holds the potential for slowing and defusing the light signal due to a lack of clarity. Polishing of the ends of the cable is therefore extremely important in optimizing the transfer of light.
Potential applications are almost limitless and the next 50 years is expected by many to bring about huge advances in the delivery of communication, lighting and entertainment solutions due to current, and as yet undiscovered, applications in our homes, businesses and civic institutions.

Computer Room AC Design – A Case For Portable Air Conditioner
333 days
Around the world these days some of the biggest energy consumers are massive computer systems. If you are running a large server system for a company, or even if you use multiple high end computers at home, you will want to know what you can do to keep your computers operating at an acceptable working temperature and humidity, and what types of computer room AC design you have at your disposal for your server room air conditioning.
In this article we will specifically address the issue of computer room air conditioning design or how to use a portable air conditioner to assure the right working temperature of your computer center, either in your home, or at the office.
We will focus here on three components of a solid computer room air conditioning system: A portable air conditioner, The (optional) raised floor, and The alert system.
Portable air conditioner
Often when running a computer room you will find that the central air conditioning system is simply insufficient to remove the adequate amount of heat from the computer room. The computers are packed in tightly and generate large amounts of heat. On top of that the computers are temperature sensitive and will malfunction when the certain ambient temperature is exceeded.
Using a supplemental portable air conditioning unit is a viable solution for a server room. Working in conjunction with the central air conditioning system, portable AC can be just as powerful if not more, and can be brought to a place where the heat needs to be removed from, such as near the computer rack. The flexible air ducts can lead either out the windows or they can lead back into the air conditioning ducts. Optionally, the flexible ducts can be guided under the raised floor. Using raised floor in conjunction with the room air conditioning units may be optional but it has many advantages.
Using raised floor in computer rooms
The portable air conditioner will work just fine without the raised floor. However, the flexible air ducts coming in and out of the portable AC unit are quite unsightly. Using raised floor as a part of the design will allow flexible air ducts to run underneath the raised floor and will at the same time provide the space to tuck electrical cables in as well, making the computer room safer and making it easy to move about in it.
Alarm system
When your computers are running enterprise critical applications, it makes sense to employ the elevated temperature alert system. The system is designed to page, or send an email or a text message to a responsible person whenever the temperature in the room exceeds a certain threshold. This can provide time for the person to get into the server room, diagnose and correct for any server room air problem before the servers go down causing financial hardship to the company.

6. Cable Routing Guides
Complete cable routing guide kits are composed of both enhanced cable brackets and vertical cable guides. The enhanced cable brackets are designed to provide better cable management entering and exiting enclosures. they allow fiber distribution frames to increase in fiber capacity by providing the ability to add or remove patch cords without disturbing neighboring fibers. The vertical cable guides manage cables routed vertically alongside the
7. Splice Trays
Splice trays provide an organized means of storing and protecting completed fiber optic splices. Bend radius protection and fold over arms prevent fibers from being damaged during handling. Each 300mm tray can accommodate up to 24 fusion splices or 12 mechanical splices. Each 200mm tray can accommodate up to 12 fusion or mechanical splices.
8. Fiber Cable Clamps
Fiber cable clamp provides a unique method for securing fiber optic cables. Each cable clamp includes a multi-diameter module that fits any size cable in its range. The multi-diameter modules adapt to fit fiber optic cables by removing a few layers from its center core. this method of securing the cable provides excellent protection and axial clamping.
