The AV6416 is one of the lowest cost Palm OTDRs currently on the market and found at eFiberTools.com. But don’t let the low cost fool you. According to the manufacturer, this handheld OTDR is designed for FTTH, installation and maintenance applications, R&D and testing. This unit has a reasonably short dead zone of 1.6m. It displays accurate of cable length, and displays the loss through connectors and fusion splices, as well as other typical physical characteristics of optical fiber cable.

The AV6416 has proven very popular with technicians in the field and at the factory. Feedback on the units features and functions have been most positive. Readings are reliable, consistent and accurate. The low-cost and the valuable features have made the AV6416 popular amongst many technicians. Manufactured with a touch-screen in a handheld device provides high-end ergonomic portability at an affordable price

The AV6416 shares much of the look and feel of some EXFO OTDRs, but at a lower price point. At several recent fiber optic expos the company claims many of the attendees walking by their exhibition booth expressed surprise to find this of blue handheld OTDR was in fact an AV6416 and was not manufactured by EXFO.

Rugged design with a rubberized protective sheath the AV6416 is lightweight and easy to operate. The low reflection LCD screen is uncomplicated to read and understand. Data is accessed using two USB interfaces to transfer traces easily and conveniently. The battery life is more than 10 hours of use time using rechargeable NiCad batteries

The Grey-Market and Fujikura Fusion Splicers

The intent of this article is an attempt to provide a solid description of what the term “gray-market” does and does not mean.

Gray-market sales by definition are legal. This is contrary however to what a plaintiff in a legal matter will wish others to believe. In my opinion, what should illegal is a company’s–usually the manufacturer– ability to price gouge one group of customers simply due to where they happen live, as well as how strong is the manufacturer’s monopoly. The strength of the monopoly is proportionate to the country’s legal system, primarily in the area of law relating to trademarks. This appears to be the case cents a significant number of cases filed appears from my perspective to be based on a trademark violation. The products manufacturer or the regions alleged authorized distributors are the ones most likely to start the action.

According to Wikipedia a grey market or gray market also known as parallel market is the trade of a commodity through distribution channels which, while legal, are unofficial, unauthorized, or unintended by the original manufacturer.

A black market is the trade of goods and services that are illegal in themselves and/or distributed through illegal channels, such as the selling of stolen goods, certain drugs or unregistered handguns. The two main types of grey market are imported manufactured goods that would normally be unavailable or more expensive in a certain country.

Unlike black market goods, grey-market goods are legal. However, they are sold outside normal distribution channels by companies which may have no relationship with the producer of the goods. Frequently this form of parallel import occurs when the price of an item is significantly higher in one country than another. This situation commonly occurs with electronic equipment such as cameras. Entrepreneurs buy the product where it is available cheaply, often at retail but sometimes at wholesale, and import it legally to the target market. They then sell it at a price high enough to provide a profit but under the normal market price. International efforts to promote free trade, including reduced tariffs and harmonized national standards, facilitate this form of arbitrage whenever manufacturers attempt to preserve highly disparate pricing. Grey-market goods are often new, but some grey market goods are used goods. A market in used goods is sometimes nicknamed a Green Market.

A related concept is bootlegging, the smuggling or transport of highly regulated goods, especially alcoholic beverages. The term “bootlegging” is also often applied to the production or distribution of counterfeit or otherwise infringing goods. Grey markets can sometimes develop for select video game consoles and titles whose demand temporarily outstrips supply and the local shops run out of stock, this happens especially during the holiday season. Other popular items, such as dolls can also be affected. In such situations the grey market price may be considerably higher than the manufacturer’s suggested retail price. Online auction sites such as eBay have contributed to the emergence of the video game grey market.

The parties most concerned with the grey market are usually the authorized agents or importers, or the retailers of the item in the target market. Often this is the national subsidiary of the manufacturer, or a related company. In response to the resultant damage to their profits and reputation, manufacturers and their official distribution chain will often seek to restrict the grey market. Such responses can breach competition law, particularly in the European Union. Manufacturers or their licensees often seek to enforce trademark or other intellectual-property rights against the grey market. Such rights may be exercised against the import, sale and/or advertisement of grey imports. In 2002, Levi Strauss, after a 4-year legal fight, prevented UK supermarket Tesco from selling grey market jeans.[4] However, such rights can be limited. Examples of such limitations include the first-sale doctrine in the United States and the doctrine of the exhaustion of rights in the European Union.

When grey-market products are advertised on Google, eBay or other legitimate web sites, it is possible to petition for removal of any advertisements that violate trademark or copyright laws. This can be done directly, without the involvement of legal professionals. eBay, for example, will remove listings of such products even in countries where their purchase and use is not against the law. Manufacturers may refuse to supply distributors and retailers (and with commercial products, customers) that trade in grey-market goods. They may also more broadly limit supplies in markets where prices are low. Manufacturers may refuse to honor the warranty of an item purchased from grey-market sources, on the grounds that the higher price on the non-grey market reflects a higher level of service even though the manufacturer does of course control their own prices to distributors. Alternatively, they may provide the warranty service only from the manufacturer’s subsidiary in the intended country of import, not the diverted third country where the grey goods are ultimately sold by the distributor or retailer. This response to the grey market is especially evident in electronics goods

Manufacturers may give the same item different model numbers in different countries, even though the functions of the item are identical, so that they can identify grey imports. Manufacturers can also use batch codes to enable similar tracing of grey imports. Parallel market importers often de-code the product in order to avoid the identification of the supplier. In the United States, courts have decided that decoding which blemishes the product is a material alteration, rendering the product infringed. Parallel market importers have worked around this limitation by developing new removal techniques.

The development of DVD region codes, and equivalent regional-lockout techniques in other media, are examples of technological features designed to limit the flow of goods between national markets, effectively fighting the grey market that would otherwise develop. This enables movie studios and other content creators to charge more for the same product in one market than in another or alternatively withhold the product from some markets for a particular time. Consumer advocacy groups argue that this discrimination against consumers—the charging of higher prices on the same object simply because of where they happen to live—is unjust and anti-competitive. Since it requires governments to legislate to prevent their citizens from purchasing goods at cheaper prices from other markets, and since this is clearly not in their citizens’ interests, many governments in democratic countries have chosen not to protect anti-competitive technologies such as DVD region-coding.

The above was taken in part from Wikipedia’s definition of gray market. This posting will be edited over time to conform more specifically to fusion splicers and other fiber optic and optical products.

Fiber Splicing Basics

In fusion splicing, the cores and cladding of the two fibers are actually melted together. The core is the central part of the fiber and has a very small diameter. The core is where the light travels through the fiber.  Because of this, it requires a very precise instrument to align and then weld the cores in such aFusion Splicerway to let them most light pass through the point of joining. The diameter of single mode fiber is about 1/100 of a millimeter, and for multi-mode fiber the diameter is 1/16 of the millimeter. For comparison, a human hair is about 1/8 of a millimeter in diameter.

Because of the small diameter of the fiber core, it is difficult to position two fibers so that their cores line up nearly perfectly. The light cannot pass through if the cores are not lined up just right. In addition, the heating of the fiber must be very exact. If not enough heat then the two ends will not melt together. Conversely, if too much heat is applied then the fiber may droop or deform and again not line up properly.

Best fusion splicers on the market today are automated. That is, when you put two properly stripped and cleaved fibers and these devices, they automatically line up the fibers, use them together, and measure the DB loss at the splice. The automated fusion splicers are designed to work with many different types and combinations of fibers. It is possible to splice different types of fibers, including the most common types single and multi-mode fibers using the splicer’s preprogrammed factory settings. Manual operation is still possible when necessary.

Splicing Procedure

Stripping the fiber:
The splicing process begins by preparing each fiber for fusion. Fibers are prepared by stripping away all of the protection, including any jacket and sheath. The fibers are then stripped of their protective polymer coating in preparation for fusion splicing. Thermal strippers are best as they minimize the risk of damage to the fiber but the most common fiber strippers look almost identical to handheld wire strippers.

Cleaning the fiber:
The bear fibers are cleaned using alcohol and wipes, or an ultrasonic cleaner.

Cleaving the fiber:
Once only beer glass remains, the fibers are then cleaved to expose a predetermined length of bare fiber. Most fiber optic cleavers on the market today use a tungsten carbide wheel or diamond blade to score, or ‘nick’, the fiber. This intentionally creates a microscopic fracture in the side of the fiber where the break is to result. Proper tension is used to pull the fiber, or a force is applied perpendicular to the longitudinal axis causing a controlled break and producing a perfectly flat endface. This is called the score-and-break, or scribe-and-break method. Properly done, cleaving leas a mirror-like finish. It should be perfectly flat and perpendicular to the axis of the fiber.

Fusion splicing:
The fibers are then clamped into the fusion splicers fiber holders, which may be fixed or removable dependent on the type of splicer. Today’s best fusion splicers will automatically identify the type of fibers being used and select the appropriate splice program, or allow manual control.

The amount of loss allowed in the fiber-optic network due to splice or connector losses, the more sophisticated the fusion splicer required. Simple splicers let the fibers align themselves during the fusion while more sophisticated machines and just the both fiber sites to match each other.

There are two basic types of fusion splicing systems in today’s fiber splicing machines, Core Alignment and Cladding Alignment.

Cladding AlignmentCore Alignment
Core Alignment:
The technique associated with the more expensive Core Alignment or Profile Alignment System (PAS) splicers use the fiber’s core to align the fibers in the splicer.

Cladding Alignment:
The other commonly used method is called Cladding Alignment or Fixed V-Groove Alignment and uses the precision v-grooves to help align the fibers. With this method instead of the fibers core it’s the outside or cladding which the splicer uses to align the fibers.

Protecting the fiber:Protective Splice Sleeves

Once the splice is completed the splice protection sleeve is slid over the fused area and bare fiber and into the heat oven.

 

Tips for maintaining your fusion splicer

Fusion splicers are expensive precision tools and must be cared for as such. Repairs can be very expensive, especially with the Japanese models. Fujikura, Fitel and Sumitomo have an uncommon control over pricing, distribution and repairs. Be prepared to pay substantially over the life of the splicer for factory maintenance. This is a good reason to take excellent care of your fusion splicer. One of the biggest concerns here is cleanliness.

Electrodes

Remember, it is not necessary to pay the exorbitant manufacturer prices for replacement fusion splicer electrodes. In several examples, we have confirmed that at least a
couple of the splicer manufacturers sell the same electrodes as sold by eFiberTools.com and other vendors. Do not pay $90-$125 when you can get them  same or better quality for half the price.

Cleaning

Carefully clean the mirrors and camera lenses to ensure proper splicing operations.
Be sure to use only 99.9% isopropyl alcohol or an approved product designed specifically for cleaning fiber optics. Dirt
removal in the precision v-grooves is imperative. You can use a piece of scrap fiber to scrape out any debris in the v-grooves or fiber holders.

Caution: Using canned air to blow out a fusion splicer can cause dirt or shards of glass to sandblast mirrors and lenses, as well as in bed this debris into motors, bearings or other moving parts.
