#indoor cable

FTTH indoor cable is made up by optical communication unit, strengthen pieces and the sheath composition, that is put the optical communication unit in the centre, both sides parallel place two root non-metallic strengthen members (FRP) or metal strengthening component phosphating steel wire, finally squeeze the black color LSZH sheath into cable.

The prevalence of fiber optic cable has become a trend which is embraced globally, since optical fiber offers unsurpassed advantages. Fiber optic cables are sensitive to excessive pulling, bending, twisting, crushing and other impact forces, for any such damage may alter the fiber property and may pose threats to its performance. So, optical cable should be stored and handled in an appropriate way. This article offers recommendations for proper storage and handling of fiber optic cable.

Fiber Optic Cable Storage

Fiber optic cable can be basically categorized into indoor fiber optic cable and outdoor fiber optic cable. Indoor cables are used exclusively within buildings whereas outdoor cables are employed in outside plant applications. Here are some factors to consider for indoor and outdoor storage.

Indoor Fiber Optic Cable Storage Recommendations

Always keep the reel tag that comes with the cable. There is vital information on the tag which indicates the cable description, attenuation, bandwidth and cable length. All these are valid identification of the fiber optic cable for future traceability.

Store fiber optic cable reels standing on both flanges, or held through center. Never store a cable reel sitting on one flange surface, which will result in possible future cable damage when unwinding.

Once rewind the fiber optic cable to another reel, the diameter of the new reel shall be compatible with the minimum bending radius of the cable. And the original cable label details should be copied to the new reel.

In no circumstances shall any indoor cable boxes or reels be stored outside or in a harsh environment. Instead, indoor cables should be stored in a dry and UV protected location, such as a room or container.

Choose a site for storage with no risk of excessive humidity, falling objects, chemical spills (oil, grease,etc.) open flames or excessive heat. Elements like moisture and other contamination should also be considered when picking storage location.

Outdoor Fiber Optic Cable Storage Recommendations

Requirements listed below are applicable to both outdoor and indoor/outdoor fiber optic cables. Ends of the cables shall be sealed during storage.

All fiber optic cable reels including part used should be stored upright. Always store the reel in areas with flat firm surfaces. And use appropriate devices to secure reels to prevent reel movement during storage.

Avoid storage areas that are susceptible to flooding, or that could damage the cable, such as sharp, uneven terrain.

When the cable reel is too heavy to lift manually, it must be moved upright by lifting the cable with a forklift or reel mover. Never drop a cable reel from any height during transportation or use.

When unloading from a vehicle, use either the tail-lift / elevator (if fitted) or a suitable mechanical aid such as a forklift truck. Never let reels drop from the vehicle to the ground.

Before de-reeling cable, the reel should be visually inspected for possible damage caused during storage.

Considerations for Handling Fiber Optic Cable

Fiber optic cable is prone to damages due to improper handling and such damages can degrade the cable performance. Therefore the following suggestions may be useful to handle fiber optic cable properly.

1. Store the cable drums in an upright position, resting it vertically on cable flange edge not in the horizontal position. The flanges of reels shall not be interleaved, and reels must not be lifted by their flanges.

2. The rolling of the drum in the direction of the arrow decreases the chance for the cable to loosen its wind on the drum. However, you should notice that when pulling the fiber optic cable off the drum to install the cable, the arrow will point in the opposite direction to the rotation of the drum. (see the picture below).

3. When moving or handling the drum by a forklift, one should operate it in a proper manner to avoid any damage to fiber optic cable. The fork should not have any direct contact with the cable jacket.

4. While removing fiber optic cable from the drum. It is essential to avoid any reverse bending or twisting that may ultimately deteriorate fiber performance.

5. Always grounding optical fiber in figure 8 configuration, which allows for pulling of cable in both directions from a central location. It is necessary to protect the figure 8 coil form passers by. The figure 8 coil should be at least 10M by 5M. So what if the longer cable is required to be unreeled? The overwhelming weight of the coil may damage the cable at the bottom. In this case, try to spread the cable out in several figure 8 coils.

Conclusion

Proper storage and handling of fiber optic cable help to decreas chances for accidental damages, yet increases longevity of fiber optic cable. This article simply offers a recommended guideline for optical fiber storage and handling, while it is always wise to consult a professional for your unique application.

Using the growing deployment associated with entry Fiber Optic Cables targeted with regard to FTTH, several set up choices are also attempted through telecommunications providers. The objective of several deployment methods would be to decrease for each customer price to ensure that aggressive FTTH broadband programs could be agreed to possible customers. Cable set up encounter states generally 70% from the outdoors grow deployment cost applies to municipal functions. Fiber optic cable price within the complete outdoors grow price is about 6% or even much less oftentimes.

Therefore this is needed in order to focus on techniques exactly where we are able to conserve municipal function price. Searching brand new ditches or even lounging brand new ducts may usually boost the outdoors grow spending budget. Because of this , system contractors look for option set up techniques to ensure that building associated with brand new route methods with regard to cable could be decreased. Fiber cable set up about the current rods aerially is definitely an choice, however it provides a good unsightly look at towards the system because energy cables, CATV cables, Indoor Cable and so on might go through exactly the same rods. Upkeep can also be hard upon aerial rods. Aerial set up is actually economical certainly because you don’t have with regard to searching as well as ducting.

Installing of fiber optic cables within sewer ducts is definitely an rising choice to set up entry fiber within an inexpensive method. Setting up fiber optic cables within sewer ducts is really a trenchless technique. The benefits of set up within sewer ducts tend to be numerous. Cable set up could be finished within much less period and also the set up isn’t disrupted through the undesirable climate conditions. Fiber optic cables set up within sewer ducts tend to be secure and therefore are guarded towards harm. Set up doesn’t trigger any kind of visitors issue within the town or even additional packed region. In the event that set up within sewer ducts, trenching or even searching along with other municipal functions which disturbs open public existence could be prevented. Optical fiber cable set up within sewer ducts is actually secure in the vibrations in the motion associated with automobiles when compared to straight hidden or even duct cables.

A few sewers tend to be man-accessible sewers although some tend to be no man-accessible sewers. The actual category associated with guy obtainable as well as no man-accessible sewers mainly depends upon the actual rules associated with person nations as well as about the rules from the sewer system proprietor or even owner. The actual no man-accessible sewer diameters can vary through 200mm in order to 700mm. Fiber Optic Cable set up within sewer ducts exactly where individuals cannot key in is actually completed along with assist associated with automatic devices or even bots. Set up within sewer ducts exactly where individuals may key in can be done along with possibly guide or even by using bots.

A few of the fiber optic cable set up methods utilized in sewer ducts is actually mentioned right here. fiber optic cables could be set up at the end from the sewer. Such methods the actual fiber cable will be large sufficient to remain at the end from the sewer through its pounds. To do this home the fiber optic cable style professional select larger metal cables which are covered about the cable internal sheath. To improve the actual pounds as well as set up tugging pressure dual levels metal cable could be used. An additional method would be to set up the actual fiber optic cable within suspension towards the top of the actual sewers. In this instance the actual fiber optic cable will be made to satisfy the self-supporting kind cable specs. ADSS Cable could be put into fulfill higher tensile power. ADSS Cable tend to be an additional choice providing you with animal safety somewhat. With regard to efficient animal safety, metal with regard to metal cable armoring is essential. The 3rd exercise would be to set up microducts within the sewer duct as well as set up microduct fiber optic cables because so when the actual need occurs.

Fiber cables set up within sewer ducts experience animal risk a lot more than every other cables. Therefore the actual optical fiber cable style ought to make sure correct animal opposition techniques through integrating needed safety supplies this kind of tend to be metal tapes, metal cables, cup tapes or even fiber strengthened plastic material fishing rod armour levels. Although the fiber optic cable cost on it’s own might be greater in comparison with immediate hidden or even duct cable styles, the entire task price is going to be a lot lower in the event that sewer duct set up technique is actually chosen.
