SELECTING A FIBER OPTIC PATCH CORD

by http://www.fiber-mart.com

fiber-mart.com receive many questions when it comes to the topic of Networks and Datacom, but one subject I believe many can benefit from is how to determine the differences between one fiber optic patch cord and another. Now, fiber optic patch cords come in a variety of cable and connector types. In order to obtain the proper patch cord you need to determine several attributes:
Cable Type — Fiber Optic cable comes in two general types, Single-Mode and Multi-Mode fiber.
Single-Mode fiber cable generally has a 9 Micron diameter glass fiber. There are two sub groups (referred to as OS1 and OS2) but most cable is “dual rated” to cover both classifications.
Multi-Mode fiber cable can have several different diameters and classifications of fiber strands.
The two diameters currently in use are 62.5 Micron and 50 Micron.
Within the 50 Micron diameter Multi-Mode cable, there are three different grades (referred to as OM2, OM3, and OM4). The cable types used in the patch cord should match that of the network cabling to which they are attached via the patch panel.
The fiber cable may be available in different “jacket diameters” (such as 2mm or 3mm). Thinner diameters (1.6 or 2mm) may be preferable in dense installation within a single rack since they take up less space and are more flexible.
Cables that route from rack to rack (especially via cable tray) may be more suitable if they have the thicker jacket that results in larger diameters thus making them more rigid.
Flammability of the jacket material could become an issue if the area they are in has special requirements for flame spread or products of combustion in case of a fire. In these cases, patch cords may have to be classified as “Plenum Rated” (OFNP) rather than “Riser Rated” (OFNR).
Simplex or Duplex — Unlike copper patch cords which send information in both directions (having multiple pairs of conductors with which to do so), most fiber patch cord cables have a single strand of fiber allowing for signal flow in one direction only.
Connecting equipment so that it can send and receive information requires two strands of fiber (one to transmit and one to receive information). This can be accommodated by using two “Simplex” (single strand of fiber) cables for each equipment interconnection or a “Duplex” cable, with conductors and/or connectors bonded together in pairs.
Length — Overall length of the patch cord may be specified in feet or meters, depending on your preference.
Connector Type — See the connector type descriptions below. Some patch cords may have different connector types on each end to accommodate interconnection of devices with dissimilar connectors. In some cases, there may be a connector on only one end, and bare or unterminated fiber on the other. These are usually referred to as “Pigtails” rather than “Patch Cords”.

How to choose the Right Fiber Optic Adapters?

by http://www.fiber-mart.com

Today, fiber-mart.com would like to introduce one of small but very important accessory in the fiber cabling field, the fiber optic adapter.
The fiber optic adapters are commonly used in the fiber optic connection field. They are used to provide a cable to cable or cable to equipment fiber optic connection. Through some many years of develop, now these fiber optic adapters have many different shapes but still all serve the same purpose, it allows the optical fiber cables to be connected to each other singly or in a large network which allowing many devices to communicate at once. While in this two types of using, the use of simply to connect two fiber optic cables to one another is the most common uses. By connecting two cables together can allow two devices to communicate from a distance through a direct connection with the fiber-optic line.
fiber-mart.com now can supply a number of different shapes of adapters. For the flange fiber optic adapters we provide, it is always be used to connect the cables which are all of the same shape. It includes many varieties such as FC, SC, ST, LC, MTRJ, SMA, DIN, MU, MPO and E2000. And even for the FC-FC fiber optic adapter, it have many types such as the Round Big D type, Round Small D type, Square solid type (one piece), (Square two pieces type), screw panel mount and so on. While for the hybrid fiber optic adapters, it is always used for the connection of two cables that are different shapes. A hybrid connector can be designed to fit any two types of fiber optic cables together, there are many different types of hybrid connectors. For example, the LC female to SC male single-mode fiber adapter, the LC female to FC male fiber adapter, the FC female to SC male fiber coupler, the FC to ST fiber optic adapter, SC to ST Duplex fiber optic adapters…And the third types of fiber optic adapters is the bare fiber optic adaptor, it allow users to make fast connection of the bare fiber and the fiber optic equipment, bare fiber optic adaptors can be used in some emergency situation for urgent connection. So much for the introduction of the fiber optic cable adapters, welcome to buy these high quality while low price fiber optic connection products on our website.

The advantage of A Good Fiber Optic Cleaver

by http://www.fiber-mart.com

To get good fiber optic splices or terminations, especially when using the pre-polished connectors with internal splices, it is extremely important to cleave the fiber properly. If the fiber ends are not precisely cleaved, the ends will not mate properly. To prepare a fiber end for a connector or splice, the end of the fiber must be cleaved to a 90 degree flat end. For technicians the problem is that the end of the fiber strand is so small that it is impossible to tell with the naked eye whether the strand has a flat end. So in order for this to happen, you must use a cleaving tool called fiber optic cleaver. Some knowledge of fiber optic cleaves will be provided in this article.

What Is Fiber Optic Cleaver?
A cleave in an optical fiber is a deliberate, controlled break, intended to create a perfectly flat end face, perpendicular to the longitudinal axis of the fiber. A fiber optic cleaver is a tool that holds the fiber under low tension, scores the surface at the proper location, then applies greater tension until the fiber breaks. Usually, after the fiber has been scored, the technician will use a cleaver either bend or pull the fiber end, stressing the fiber. This stress will cause the fiber to break at the score mark, leaving a 90 degree flat end if all goes well. So the cleaver doesn’t cut the fiber. In fact, it just breaks the fiber at a specific length.
Two Types of Fiber Optic Cleavers
We know that the closer to 90 degrees the cleave is, the more success you will have with matching it to another cleaved fiber to be spliced or mated by a connector. So it’s important to use the proper tool with good technique to consistently achieve a 90 degree flat end. Good cleavers are automatic and produce consistent results, irrespective of the operator. The user need only clamp the fiber into the cleaver and operate its controls. Some cleavers are less automated, making them more dependent on operator technique and therefore less predictable. There are two broad categories of fiber optic cleavers, scribe cleavers and precision cleavers.
A traditional cleaving method, typically used to remove excess fiber from the end of a connector before polishing, uses a simple hand tool called a scribe. Scribe cleavers are usually shaped like ballpoint pens with diamond tipped wedges or come in the form of tile squares. The scribe has a hard, sharp tip, generally carbide or diamond, that is used to scratch the fiber manually. Then the operator pulls the fiber to break it. Since both the scribing and breaking process are under manual control, this method varies greatly in repeatability. Most field and lab technicians shy away from these cleavers as they are not accurate. However, if in skilled hands, this scribe cleaver offer significantly less investment for repairs, installation, and training classes.
Scribe
Precision cleavers are the most commonly used cleavers in the industry. They use a diamond or tungsten wheel/blade to provide the nick in the fiber. Tension is then applied to the fiber to create the cleaved end face. The advantage to these cleavers is that they can produce repeatable results through thousands of cleaves by simply just rotating the wheel/blade accordingly. Although more costly than scribe cleavers, precision cleavers can cut multiple fibers while increasing speed, efficiency, and accuracy. In the past, many cleavers were scribes, but over time, as fusion splicers became available and a good cleave is the key to low splice loss, precision cleavers were developed to support various applications and multiple fiber cleaving with blades that have a much longer life span.

Which One to Use: Scribe Cleaver or Precision Cleaver?
ST-105 Fiber Optic Cleaver
While both types perform the functions above, the difference between the two categories of cleavers is the percentage yield of good cleaves. An experienced fiber optic technician will achieve approximately 90% good cleaves with a scribe cleaver, while the precision cleaver will produce 99% good cleaves. The difference doesn’t seem like much so you may hardly to make a specific decision. My suggestion is to buy precision cleavers if you plan to use a lot of mechanical splices or pre-polished splice/connectors. It will pay for itself in no time. If you decide to use the inexpensive scribe cleavers, you must learn how to use it properly. Follow directions, but also do what comes naturally to you when using the device, as they are sensitive to individual technique. Inspect the fibers you cleave to see how good they are and keep practicing until you can make consistently good cleaves.

The types of Outdoor Fiber Optic Cables

by http://www.fiber-mart.com

Fiber optic cable provides protection for the fibers from the environment encountered in an installation. Outdoor Fiber Cable is designed strong to protect the fibers to operate safely in complicated outdoor environment, it can be buried directly, pulled in conduit, strung aerially or even placed underwater. While indoor cables don’t have to be that strong.
Outdoor fiber optic cable is composed of many fibers enclosed in protective coverings and strength members. Common features for fiber optic cable include polarization maintaining, graded index, and metalization. Most outdoor fiber cables are loose buffer design, with the strengthen member in the middle of the whole cable, the loose tubes surround the central strength member. Inside the loose tube there is waterproof gel filled, whole cable materials used and gels inside cable between the different components will help make the whole cable resist of water.
 Single-Armored Tight Buffered Water-proof Indoor Outdoor Cable
Typical outdoor fiber optic cable types are used for aerial, direct buried and duct applications.
Loose Tube Cables
Loose Tube cables are the most widely used cables for outside plant trunks, as it can be made with the loose tubes filled with gel or water absorbent powder to prevent harm to the fibers from water. Loose Tube Fiber Optic cables are composed of several fibers together inside a small plastic tube, which are in turn wound around a central strength member and jacketed, providing a small, high fiber count cable. They can be installed in ducts, direct buried and aerial/lashed installations for trunk and fiber to the premise applications. Loose tube cables with singlemode fibers are generally terminated by spicing pigtails onto the fibers and protecting them in a splice closure. Multimode loose tube cables can be terminated directly by installing a breakout kit, also called a furcation or fan-out kit, which sleeves each fiber for protection.
Ribbon Cable
Ribbon cable is preferred where high fiber counts and small diameter cables are needed. This cable has the highest packing density, since all the fibers are laid out in rows in ribbons, typically of 12 fibers, and the ribbons are laid on top of each other. Not only is this the smallest cable for the most number of fibers, it’s usually the lowest cost. Typically 144 fibers in ribbons only has a cross section of about 1/4 inch or 6 mm and the jacket is only 13 mm or 1/2 inch diameter! Some cable designs use a “slotted core” with up to 6 of these 144 fiber ribbon assemblies for 864 fibers in one cable! Since it’s outside plant cable, it’s gel-filled for water blocking or dry water-blocked. These cables are common in LAN backbones and data centers.
Armored cable is used in direct buried outside plant applications where a rugged cable is needed and/or for rodent resistance. Armored cable withstands crush loads well, for example in rocky soil, often necessary for direct burial applications. Cable installed by direct burial in areas where rodents are a problem usually have metal armoring between two jackets to prevent rodent penetration. Another application for armored fiber optic cable is in data centers, where cables are installed under the floor and one worries about the fiber cable being crushed. This means the cable is conductive, so it must be grounded properly.
Aerial Fiber Optic Cable
Aerial cables are for outside installation on poles. They can be lashed to a messenger or another cable (common in CATV) or have metal or aramid strength members to make them self supporting. A widely used Aerial Cable is optical power ground wire (OPGW) which is a high voltage distribution cable with fiber in the center. The fiber is not affected by the electrical fields and the utility installing it gets fibers for grid management and communications. This cable is usually installed on the top of high voltage towers but brought to ground level for splicing or termination.
Indoor/Outdoor Cables
Fiber Optic Indoor/Outdoor Cables are designed to meet both the stringent environmental requirements typical of outside plant cable AND the flammability requirements of premise applications. Ideal for applications that span indoor and outdoor environments. By eliminating the need for outside to inside cross-connection, the entire system reliability is improved and with lower overall installation costs.
It is often necessary to install fibers under water, such as crossing a river or lake where a bridge other above water location is not possible. For simple applications a rugged direct burial cable may be adequate. For true undersea applications, cables are extremely rugged, with fibers in the middle of the cable inside stainless steel tubes and the outside coated with many layers of steel strength members and conductors for powering repeaters. Submarine cables are completed on shore, then loaded on ships and laid from the ship, often while operational to ensure proper operation.
fiber-mart.com offers a comprehensive range of multimode fiber cable and single-mode fiber optic cables. Indoor, outdoor, armoured, tight buffered or loose tube structures, which cover all possible applications.
