Understanding OTDR Dead Zone Specifications. OTDR (Optical Time Domain Reflectometer), as one of the important fiber optic testers, is most commonly used by technicians or installers to certify the performance of new fiber optic links and detect the issues of existing fiber links. There are some specifications of an OTDR which may affect its performance. To understand these specifications can help users get maximum performance from their OTDRs.
Today, one of the key specifications—Dead Zone will be introduced here. Definition of Dead Zones The OTDR dead zone refers to the distance (or time) where the OTDR cannot detect or precisely localize any event or artifact on the fiber link. Why Is There a Dead Zone? In simple terms, OTDR dead zone is caused by a Fresnel reflection (mainly caused by air gap at OTDR connection) and the subsequent recovery time of the OTDR detector. Types of Dead Zones In general, there are two types of dead zones on an OTDR trace—event dead zone (EDZ) and attenuation dead zone (ADZ). Event Dead Zone Conclusion. Why Not Choose a PoE Switch? The Power over Ethernet (PoE) lets Ethernet cables supply the power for network devices, at the same time as transmitting data in the normal way.
Typical PoE users are businesses adding to their network or adding VoIP phones in buildings where new power lines would be expensive or inconvenient. So why not choose a PoE switch? PoE switches give you an easy way to add PoE devices to your network. The plug-and-play switches will automatically detect whether connected devices are PoE or PoE+ and send power accordingly. What Is Power over Ethernet? Currently, there are two standards approved by the IEEE. Upgrade to PoE with a PoE Switch A basic PoE-based system usually consists of three main components: power-sourcing equipment (PSE), such as a PoE switch, category network cable and remote-powered devices, which may be an IP camera, IP access panel, IP intercom, VoIP or wireless access point (WAP).
How to Choose a PoE Switch? Fiber Media Converter Tutorial. Fiber media converter is a cost-effective solution to overcome the bandwidth and distance limitations of traditional network cable. It dramatically increases the bandwidth and transmission distance of the local area network (LAN) by allowing the use of fiber and integrating new equipment into existing cabling infrastructure. To better understand it, this article will give an overview of fiber media converter.
What’s Fiber Media Converter Fiber media converter is a transfer media that connects two dissimilar media types. Generally, it is a device that converts electrical signal used in copper unshielded twisted paired (UTP) network cabling into light waves used in fiber optic cabling, and vice versa. This kind of fiber media converter is called copper-to-fiber media converter that provides a simple way to introduce fiber into a LAN without tearing out the existing copper wiring or making changes to copper-based switches.
Types of Fiber Media Converters Managed VS Unmanaged Mode Converter. Fiber Patch Cable Management. Deploying more fiber optic cable is just the first step to meet the high-bandwidth requirements, strong management over the fiber optic cable is a basic requirement for a successful fiber optic network infrastructure. Fiber patch cable might be the weakest link in optical network infrastructures. To deliver and guarantee and optimal network performance, patch cable management is critical. In addition, well management of fiber patch cable can lower operation cost & time and increases the reliability and flexibility of network operation and maintenance.
This post will offer the critical elements that should be noted during patch cable management, as well as tips for fiber patch cable management. Elements That Affects Patch Cable Management To get a flexible and well organized patch cable management, the factors that affect the performance of the fiber optic patch cable should be introduced first.
Bend Radius Path of Patch Cable Accessibility of Patch Cable Physical Protection Conclusion. Comparison Between EPON and GPON. PON is the abbreviation of passive optical network, which only uses fiber and passive components like splitters and combiners. EPON （Ethernet PON) and GPON (Gigabit PON) are the most important versions of passive optical networks, widely used for Internet access, voice over Internet protocol (VoIP), and digital TV delivery in metropolitan areas. Today we are going to talk about the differences between them. Technology Comparison EPON is based on the Ethernet standard 802.3 that can support the speed of 1.25 Gbit/s in both the downstream and upstream directions. As the parts of PON, they have something in common.
Costs Comparison No matter in a GPON or in an EPON, the optical line terminal (OLT), optical network unit (ONU) and optical distribution network (ODN) are the indispensable parts, which are the decisive factor of the costs of GPON and EPON deployments. The cost of OLT and ONT is influenced by the ASIC (application specific integrated circuit) and optic module. Summary. WBMMF – Next Generation Duplex Multimode Fiber in the Data Center. Enterprise data center and cloud operators use multimode fiber for most of their deployments because it offers the lowest cost means of transporting high data rates for distances aligned with the needs of these environments.
The connections typically run at 10G over a duplex multimode fiber pair—one transmit (Tx) fiber and one receive (Rx) fiber. Upgrading to 40G and 100G using MMF has traditionally required the use of parallel ribbons of fiber. While parallel transmission is simple and effective, continuation of this trend drives higher cost into the cabling system. However, a new generation of multimode fiber called WBMMF (wideband multimode fiber) is on the way, which can enable transmission of 40G or 100G over a single pair of fibers rather than the four or ten pairs used today. Now, let’s get close to WBMMF. What Is Wideband Multimode Fiber? What Is the Technology Behind WBMMF? Why Does WBMMF Make Sense? Splice or Connector, Which to Choose for FTTH Drop Cable Installation? - Optical Cables on Fiberstore. To choose a right drop cable interconnection solution for FTTH network is very importance. Connectors and splice, as the two common ways to interconnect drop cables, are widely used at FTTH deployment.
We all know that the splice can offer a permanent joint, while the connector can be easily operated by hand. But there is a proverb that says you can’t have your cake and eat it too, the providers have to choose between the two. So which should we choose? This paper is going to discuss them in details via talking about their own advantages and disadvantages.
Pros and Cons of Splice Let’s first go with the splice. And then let’s talk about its disadvantages. Pros and Cons of Connector Unlike splice, connector can provide great operational flexibility in that they can be mated and unmated repeatedly, allowing them to be reused over and over again. Also, connector has its own disadvantages, just as every coin has two sides. Conclusion From the above analysis, now we can draw a conclusion. Do You Know Virtual Data Center? Data centers are important to our daily life and work.

Second, it can provide virtually unlimited bandwidth capacity. Third, it brings profits to your home and the community. Two Factors You should know before deploying FTTH Conlusion. Lower FTTH Cost and Increase Reliability With Tight Buffer Indoor/Outdoor Cable. FTTH (Fiber to the Home) network connects a large number of end users to a central point known as an access node to provide the application and services of high speed. The links between end users and access node are achieved largely by fiber optic cables.
Loose buffer cables and tight buffer cables are commonly used to transmit signals with high speed, which are capable of surviving outdoor environment or indoor environment. However, to accomplish the whole transmission link, loose buffer cables for outdoor application should be connected with the tight buffer cables for indoor application. The splicing and termination of these fiber optic cables come as one of the largest link items in a FTTH system installation budget. Is There A Better FTTH Cable Solution? Is there a cost-effective and time-saving solution by using a single type of cable that can survive both indoor and outdoor environment in FTTH network?
Loose Buffer VS Tight Buffer A Better Choice for FTTH Cable Solution Cost. How Much Do You Know About Modular Data Center? Recently, the big movie “James Bond – Spectre” is being shown in China.

Over the last decade, large enterprises have been migrating data center infrastructures from 100MB Ethernet to 1/10 Gigabit Ethernet (GbE) to support high-bandwidth, mission critical applications. However, many mid-market companies found themselves restricted from this migration to 10GbE technology due to cost, low port density and high power consumption. For many of these companies, the explosive growth of technologies, data and applications is severely taxing existing 1GbE infrastructures and affecting performance. So it’s high time for them to upgrade the data center to 10GbE.
With many 10GbE interfaces options such as CX4, SFP+ Fiber, SFP+ Direct Attach Copper (DAC), and 10GBASE-T offered, which one is your best option? Data Center Needs to Upgrade to 10GbE With the increase in server consolidation through virtualization in the data center, the resulting data demand has exceeded traditional 1Gb/s throughput capabilities. UTP Cables Selection Guide - Optical Cables on Fiberstore. Since the copper cable is capable of the advantages, such as less expensive electronics and flexibility, the fiber optic cable can’t just replace it.
As a result, while the consumer electronics keep going increasingly wireless, many LANs still rely heavily on copper cables to handle all the heavy lifting when it comes to transmitting data. For example, if you want to plug your computer into a broadband Internet connection, you just need a cable to complete this connection.
This paper will introduce some common categories of copper cable used in today’s networks. Category 3 The CAT3 cable is an UTP (unshielded twisted pair) cable whose data transmission rate is at the speed of 10Mbps. It is one of the oldest copper cable, and was used on a large scale in the early 90’s when it was the industry standard for computer networks. Of course, it is still used today for wiring offices and homes. Category 5 As the successor of the CAT3 cable, CAT5 cable is capable of superior performance.
