Fiber Patch Panel Termination

It seems that we have already known that the fiber patch panel is the bridge of fiber patch cables. Fiber patch panel, also known as fiber distribution panel, serves as a convenient place to terminate all the fiber optic cable running from different rooms into the wiring closet and provides connection access to the cable’s individual fibers. Fiber patch panels are termination units, which are designed with a secure, organized chamber for housing connectors and splice units.

How Does Patch Panel Termination Units Works?

We know that there are two major termination solutions for fiber cable: field terminated and pre-terminated. The pre-termination, with most devices terminated by the manufacturers in advance, requires less efforts when installing than field termination does. Therefore, this post is going to offer a glimpse into the field termination which describes the termination of the fiber optic cable in the field or the termination after installation.

Fiber Patch Panel Termination Procedure

In the termination process, the fiber optic cable need to be pulled between two points, then connectors will need to be attached and then connected to a patch panel. In addition, before they can be attached to a panel, connectors need to be attached to each individual strand, and a variety of tools will be needed. With field termination, we can determine the cable length accordingly, and fiber optic bulk cable is very easily to pull from either end of the installation circuit.
To carry out the termination, such tools are needed as fiber optic enclosure, fiber cable, patch panel, cable ties, connector panels, permanent marker, fiber optic stripper, cleaver, metric ruler and rubbing alcohol.

To terminate the cable, first slide the boot onto the fiber. Strip the fiber to at least about an inch and a half . Place a mark at 15.5 mm for ST and SC connectors or at 11.5 mm for LC connectors. Clean the stripped fiber with an alcohol wipe and remove any debris. Set the stripped fiber into the cleave and cleave it. Insert the cleaved fiber into the rear of the connector until the mark align with the back of the connector body. Slight the boot up and over the rear of the connector body. After the termination, transmission testing of assemblies need to be performed.

In the final fiber patch panel termination, first, open the front and rear door of the patch panel, and remove the covers. Remover the inter stain relief bracket. Second, use cable ties to put the cables on the bracket. The fibers should be put inside the clips on the tray to segregate the fibers from A and B slots. Put the patch panel into the panels clips. Take the excess fiber slack into the slack management clips. Make a bend in the fiber to maintain slight pressure on the connection.

Conclusion

The processes in the device connection and cable management are linking with each other that missing any or failure in any one will result in the imperfect system, or even the damage. If we own a fiber patch panel, we should make full use of its termination function. The products provided by FS,COM enable you to perfect your cabling system.

Tips for Fiber Cable Installation You Should Know

Fiber cable installation is not an easy task for most of us. It’s thought as the job of professional engineers since special training is needed during the complicated process. But it would be better if you know knowledge of fiber cable installation in case that you need to run fiber cable in your home or business. This article is going to offer you some tips for fiber cable installation.

Before Fiber Cable Installation

Before starting fiber cable installation, please make sure there is fiber optic service in your area. If it’s available, find the nearest distribution box. What you need to do is to run fiber cable from the box to your house.

A considerate plan is the first step of successful fiber cable installation. Carefully design the cabling route. It would be better if you mark where the cable goes, into the walls, or underground, or through conduit… Point out all the termination points and splice points. At the same time, write down any potential problems you may come across during the installation. A good plan is also beneficial to avoid fiber cable waste.

Once finish the plan, you’re going to buy fiber optic cable for your applications. Except fiber optic cable, you need tools for cable management & installation, fiber splicing and fiber testing. So make a shopping list for your fiber cable installation. Then select a reliable fiber cable supplier who can meet the requirements of both high quality and low cost.

During Fiber Cable Installation
What You Should Do

Leave spare cable length—Each fiber cable for installation should be a few inches longer than the plan says. Because you can’t make sure everything goes as you wish. So you should leave plenty of spare fiber cables when beginning cable installation work.

Avoid electrical interference—Though fiber cable is not as vulnerable to electrical noise as copper cables, some devices, such as the boxes for fluorescent lights, may cause interference. So keep your fiber cable three or more feet from those devices.

Avoid end face contamination—The tip of fiber optic connector can be easily contaminated or damaged. So leave protective caps on until you are ready to plug into the equipment. Don’t forget to inspecting the end face before plugging in. If there is any contaminate, clean it.

Fiber network testing—Test each section of your fiber optic network. That’s easy to discover the problem and troubleshoot it. Don’t do this work until you finish the entire cable installation. In that situation, it’s hard to find out the trouble if the network fails.

What You Should Not Do

Don’t bend fiber cables. Fiber optic cables perform the best when it is running straight. But during installation in reality, sometimes bending can’t be avoided. Cables from different vendors may have different standards of bend radius. Or you can buy bend insensitive fiber cable for better performance.

Don’t pull too hard on the cable. Properly pull the fiber cable to avoid bending or snagging through the conduit or underground. However, don’t pull it too hard especially when the fiber cable is too short. Otherwise, it would ruin the cable or fiber optic connector.

Don’t mix and match different core sizes. Fiber optic cables are typically color coded. From the outside cable jacket, you can get information about fiber core sizes. To know more about fiber cable jacket, you can visit my last blog What Can We Get From Fiber Cable Jacket?

Don’t pinch the fiber cable. Pinch the fiber cable can squeeze the fiber and affect link performance. When use zip-ties, pay attention to this point.

Conclusion

Once you finish fiber cable installation, you can enjoy fiber optic network. See, fiber cable installation is not as tough as you think. Follow these tips mentioned above when you run cables for your house, you can keep away from most bothering issues.

What Can We Get From Fiber Cable Jacket?

Fiber optic cable is applied as the most advanced communication medium by more and more users. Compared with copper cable, it can support more and better optical signal transmission of voice, data, video, etc. and offer many other advantages. When purchasing fiber optic cables, you must see the cable jacket at first. So what information does the outside jacket tell? What type of cable jacket should you select? Come with me to find the secrets of fiber cable jacket.

Fiber Cable Jacket Introduction

Fiber optic cable is constructed very complicated from the inside core, cladding, coating, strengthen fibers to the outside cable jacket. The core made of plastic or glass is the physical medium for optical signal transmission. As bare fiber can be easily broken, cable outer jacket is needed for fiber protection. The cable jacket is the first line of moisture, mechanical, flame and chemical defense for a cable. Without the jacket, fiber optic cables are very likely to be damaged during and after installation.

Fiber Cable Jacket Characteristics

In most situations, robust cable jacket is better because the environment above or underground may be harsh. For better applications, you’d better take cable jacket seriously. Cable jacket is not as easy as you think. There are many characteristics you need to consider. Except the flexibility, it should withstand very low and high temperature. Whether the cable jacket has the good features of chemical and flame resistance. All these characteristics depend on cable jacket materials.

Fiber Cable Jacket Materials

Cable jacket is made of various types of materials. As mentioned above, the cable jacket should stand the test of different environmental conditions, including the harsh temperature, the sun & the rain, chemicals, abrasion, and so on. The following shows several common cable jacket materials for your reference.

PE (Polyethylene)—PE is the standard jacket material for outdoor fiber optic cables. It has excellent properties of moisture and weather resistance. It also has the good electrical properties over a wide temperature range. Besides, it’s abrasion resistant.

PVC (Polyvinyl Chloride )—PVC is flexible and fire-retardant. It can be used as the jacket materials for both indoor and outdoor cables. PVC is more expensive than PE.

LSZH (Low Smoke Zero Halogen)—LSZH jacket is free of halogenated materials which can be transformed into toxic and corrosive matte during combustion. LSZH materials are used to make a special cable called LSZH cable. LSZH cables produce little smoke and no toxic halogen compounds when these cables catch fire. Based on the benefits, LSZH cable is a good choice for inner installations.

Fiber Cable Jacket Color

Fiber cable jacket color depends on the fiber cable type. Fiber cable includes single-mode and multimode types. For single-mode fiber cable (Blog about single-mode fiber cable please read my blog What Are OM1, OM2, OM3 and OM4?), the jacket color is typically yellow. While for multimode cable ( more details on multimode fiber cable ), the jacket color can be orange (OM1&OM2 cable), aqua (OM3 cable) and purple (OM4 cable). For outside plant cables, the jacket color is black.

How to Choose Fiber Cables?

To choose a fiber optic cable depends on your own applications. I’ll talk about this from two sides of jacket color and jacket material. The cable jacket color is not just for good looking. Different color means different fiber mode. Which one suits you the most, the yellow or orange fiber cable? You should know well about the color codes before buying your fiber cables. What’s more, you should also consider the installation requirements and environmental or long-term requirements. Where will be your fiber cables installed, inside or outside the building? Will your cables be exposed to hash environment very long? This can help you decide which jacket material is the best.

Summary

As a popular data transmission medium, fiber cable plays an important role in communication field. To some degree, the success of fiber connectivity lies in a right fiber cable. How to buy suitable fiber optic cables? This article describes the method from cable jacket. When selecting fiber cable, many other factors still need to be considered. Hope you can get your own fiber cable.
