Troubleshoot the PON Network

1. Cable failureFiber optical cable interruption leads to equipment without light, or cable damage causes excessive light attenuation. This kind of failure has a large impact, which can easily lead to no access to a large number of users.When such a failure occurs, the number and distribution of the number of users first determine probable areas and distribution of the number of users. Arrange on the scene to test the optical signal strength with the optical power meter.1). No light: basically judge that the cable is interrupted. The personnel on the scene can found breakpoint along the cable path. If it is the main cable failure, promptly notify the city sub-traffic maintenance to arrange line repair.2). Too large light attenuation: focus on the inspection that whether optical cable or pigtail is damaged or loose joints. The fixed network maintenance personnel use the optical power meter to test the optical power hop by hop, find the fault point and repair.2. Equipment power supply fa..

Splicing or terminating, which is more suitable for the installation of fiber optic cable in FTTH?

Fiber optic connection and fiber termination are two common methods for installing FTTH fiber towels when laying fiber (FTTH) to different networks. Different methods have different reliability, flexibility and laying costs for the network. The impact of this tutorial will be described in detail.Optical fiber splicingOptical fiber connection by hot or cold connection method to connect two optical fiber, the advantage is that the fiber connection point can be well protected, providing good optical performance, not because of physical damage or pollution caused by fiber loss. However, there are some drawbacks to fiber splicing, such as fiber splice points that need to be installed in fiber splice disks, which are typically used in optical network termination boxes, which increases the volume and cost of optical network termination cartridges to a certain extent. Fiber connection is divided into two kinds of fiber welding and mechanical connection, respectively, the following two details:..

How to use fiber optic fast connectors?

The widespread use of fiber-to-the-home (FTTH) facilitates the rise of the fiber optic fast connector, it is small in size and fast terminating, and are less expensive and have high stability, which is indispensable optical fiber connection device.Introduction of fiber optic quick connectorThe fiber optic fast connector is a highly innovative field termination connector that includes factory-installed fiber, pre-cast ceramic ferrule, and a mechanical connection mechanism. The introduction of fiber or indoor fiber inserted into the mechanical connection mechanism can be, without the help of other tools, termination process as long as 2 minutes or so, greatly saving the installation time. Fiber optic fast connectors on the market today can be terminated with single-mode fiber and multimode fiber with diameters of 250 μm, 900 μm, 2.0 mm and 3.0 mm.Characteristics and application of fiber optic quick connectorMain featureContinued stability Good insertion loss Small use of very low install..

Why Do We Need Optical Fiber to Get to the “Cloud”?

In the past several decades, technologies have evolved almost immeasurably, certainly including the development of data storage. Humankind has always tried to find ways to store information. People have become accustomed to technological terminology, such as CD-ROM, USB Key, and DVD. But today, the most advanced storage solution may be the cloud computing. About how to achieve the “cloud”, some people say that optical fiber is the key to cloud computing. So, what is cloud computing and why do we need optical fiber to get there? Today, we are going to the “Cloud” and find the out answer.What is Cloud Computing and Why is it Called as “Cloud”?Though the term “cloud computing” is everywhere and closely linked with our life, we do not really know what it is just like many terminologies that we don’t know. However, unlike other terminologies, we are more interested in cloud computing because of its attractive features, applications or maybe the interesting name. Why is it called as “cloud” ..
