They are mostly used in indoor, short-distance, and low-stress applications. Table of Contents: The FOA Reference Guide To Fiber Optics. If you want to connect the cable directly to active devices like LEDs, VCSELs, and detectors, the ferrule design is your best bet. Fiber is not free to "float", tensile strength is not as great. Difference Between Loose-tube and Tight-buffered Fiber Optic Cable. So you've got some quotes for a new fibre optic infrastructure – One for a loose tube fibre, one for tight buffered?
The following are user-based proposals to determine categories of loose tight buffer materials: - Micro Loose Tube: A hard engineering polymer loosely surrounding a coated optical waveguide where the gap is equal to ½ the coated optical waveguide diameter or less and there is no interstitial material between the coated optical fiber and the buffer tube. There are many more definitions than standards on tight buffer strip ability. The Difference Between Tight Buffered and Loose Tube Fibre Cables. Each modular buffer tube holds up to 12 strands and this design makes it easier for drop-offs of fiber to intermediate points without bothering other modular buffer tubes. Actually, when talking about optical fiber cables, you may be confused about their several standards of classifications, such as connector construction standard and transmission media standard. Suddenly, with many different applications for removable buffers, the proliferation of test methods and strip lengths increased exponentially. The Tight-Buffered Cables With Versatility. Tight-buffered cables, in contrast, are preferred for indoor applications. According to different uses, tight buffer optical cables can be divided into trunk optical cables, horizontal optical cables and working area optical cables. The jelly provides additional protection for the fibers and helps to seal the tubes, making the cable more resistant to water and other environmental factors. Some of the specific areas of concern were epoxy bonding, buffer materials compatibility and shrinkage of the buffer. They are commonly for in outdoor and long-distance applications, such as underground and aerial installations, where the cable is into the environment. For splicing long cable runs from similar cables (called concatenation), like color fibers are spliced to ensure continuity of color codes throughout a cable run. In contrast, tight-buffer fiber optic cables are designed to protect the fibers from mechanical stress and to make them easy to handle and terminate, they are more suitable for indoor, short-distance, and low-stress applications, such as in buildings, data centers and campus networks, where the cable is protected from environmental factors such as water and UV radiation.
This type of cable is ideal for outside plant trunking applications, as it can be made with the loose tubes filled with gel or water absorbent powder to prevent harm to the fibers from water. We've looked at how the construction of tight buffered vs loose tube fibre cables affects the cost, handling, and applications of each and the differences. This includes any material weight gain or swelling. By installing a "cable" which is just a bundle of empty plastic tubes, you can "blow" fibers into the tubes using compressed gas as needed.
Another perk is that there's no need for a fan-out kit for splicing or termination. The fundamental difference between tight buffered and loose tube fibre cables is the construction of the fibre optic cable. Everyone is concerned with project budgets, material costs, and installation time, but let us not become penny-wise and pound-foolish. The fibers are double buffered and can be directly terminated, but because their fibers are not individually reinforced, these cables need to be broken out with a "breakout box" or terminated inside a patch panel or junction box to protect individual fibers. The gel within the loose-tube construction stops the penetration of water and keeps it away from the fiber. Fitting rugged coating. Multiple 250 m strands of fiber form a loose tube fiber cable that can be manufactured dry-laid or gel-filled. In the loose tube method the fiber is enclosed in a. plastic tube that is larger in inner diameter than the outer diameter of the. The tubes are placed in a central strength member, typically made of steel or aramid, and wrapped with a jacket.
Historically, loose-tube gel-filled cable has been used for outdoor long-haul routes. As can be seen from Table 2, there are several additional properties that must be taken into consideration. Also contains various strength members to protect the delicate fiber from the. Aramid threads or strength members that provide stiffness are usually present in loose tube fiber cables. Generally, indoor/outdoor cable is available in two designs: loose-tube and tight-buffered. You should contact several cable manufacturers (two minimum, three preferred) and give them the specs. These are related to the absolute strip force exerted on the optical fiber when in the act of stripping and secondly, the length of material that can be stripped in one action. The fibers are placed inside loose-fitting tubes, which are surrounded by the central strength member and a jacket. The tight buffer optical fiber has the characteristics of small volume and good mechanical strength, but when the external environment changes, it is vulnerable to influence, that is, poor temperature characteristics. The actual need is a tight buffer that has a slightly less mechanical grip on the coating but is still not loose on the coating. Larger fiber counts such as 48 fibers, 96 fibers and 144 fibers are also available for specific applications. This method of termination requires no splicing nor does it demand the use of a splicebox which is basically a protective enclosure for the cable ends. The other fiber protection technique, tight buffer, uses a direct extrusion of plastic over the basic fiber coating. Tight-buffered cables offer the flexibility, direct connectability and design versatility necessary to satisfy the diverse requirements existing in high performance fiber optic applications.
It also requires that you know exactly what you are doing. These conditions include a wide operation-temperature range, thermal shock, wind loading, ice loading, moisture, and lightning. Still Need Re-Assurance? In the tight buffer construction, a thick coating of a. plastic-type material is applied directly to the outside of the fiber itself. To select the right fiber optic cable, there are more than one type of cables that may fit the bill for many applications. Buffer tubes are typically used in tight-buffered fiber optic cables, which are designed for use in short-distance, indoor and customer premises applications. For tight buffer designs, each fiber is coated with a plastic, usually with an outside diameter of 900 micron. There is a stereotype about Tight-Buffered construction that says it cannot be installed in outdoor applications; that Loose-Tube Gel-Filled Fiber is the only way to ensure water-blocking properties. Both of these issues add to the overall cost of using Loose-Tube Fiber. Fiberglass or similar "stiff" member is also included to prevent the cable from. Cable installed by direct burial in areas where rodents are a problem usually have metal armoring between two jackets to prevent rodent penetration. Loose tube cable provides stable and highly reliable optical transmission performance over a wide temperature range, the best protection for the fibers under high pulling tensions, and can be easily protected from moisture with water-blocking gel.
In the past, standard strip testing of tight buffer fibers has used two pass/fail criteria. In that case, other factors such as ease of use, size, and cost will be added to the evaluation and selection process. There are two ways fiber optic splicing can be done: Mechanical splices: this kind of splicing is normally used when a quick solution is needed. The loose tube design also helps in the identification and administration of fibers in the system. This kind of fiber optic cable is easy to install and maintain. At the other extreme is cable suitable only for indoor use. And most manufacturers of indoor/outdoor cable is to refine the design of loose-tube cable to make it suitable for interior use.
These two fibers begin with the same 250um bare fiber that features the same size fiber core (like 50um or 62. Loose-tube 250um fiber cables are typically used in outside plant (OSP) applications, such as inter-building duct, aerial and direct buried installations. No protection from rodents and crushes. Adding a connector to each and every optical fiber in a cable is of what fiber cable termination consists. First of all, Loose-Tube OSP can only be used outdoors. If armoring is required, a corrugated steel tape is formed around a single jacketed cable with an additional jacket extruded over the armor. Will the cable become wet or moist? That means the jacket must be rated for fire resistance, with ratings for general use, riser (a vertical cable feeds flames more than horizontal) and plenum (for installation in air-handling areas. Loose Tube Fiber Optic Cable.
Environmental stresses that the cable will be subjected to.
