I'm interested in optical communication products.
The Application of EDFA - Fiber Optical Networking. 1.Introduction Optical amplifiers is the critical technology for the optical communication networks, enabling the transmission of many terabits of data over distances from a few hundred kilometers to thousands of kilometers by overcoming the fiber loss limitation. As the first optical amplifier commonly used in optical communications systems, EDFA has resulted in a dramatic growth in transmission capacity with the deployment of WDM systems. Be equipped with the features of high output power, high gain, wide bandwidth, polarization independence and low noise figure, EDFAs have become one of the key components used in the new-generation optical communication system.
This article is intended to give an overview of EDFA application to help you better understand EDFA. 2.What is EDFA? Erbium-doped fiber amplifier (EDFA) is an optical repeater device that is utilized to boost the intensity of optical signals being carried through a fiber optic communications system. 3.1 Forms of application. Key Components to Form a Structured Cabling System - Fiber Optical Networking. Building a structured cabling system is instrumental to the high performance of different cable deployments. Typically, a structured cabling system contains the cabling and connectivity products that integrates the voice, data, video, and various management systems (e.g. security alarms, security access, energy system, etc.) of a building. The structured cabling system is based on two standards. One is the ANSI/TIA-568-C.0 of generic telecommunications cabling for customer premises, and another is the ANSI/TIA-568-C.1 of commercial building telecommunications cabling for business infrastructures.
These standards define how to design, build, and manage a cabling system that is structured. Six key components are included to form a structured cabling system. Six Subsystems of a Structured Cabling System Generally speaking, there are six subsystems of a structured cabling system. Horizontal Cabling Backbone Cabling Backbone cabling is also known as vertical cabling. Work Area Equipment Room.
How to Choose the Right Switch for Your Data Center? If you plan to set up a 10G network, what do you need? The answer is 10G switch, 10G transceiver and optical cable. In addition, the option of switch is the most basic and important step to start the network deployment. How to choose the right switch for your data center? This article will introduce the three-tiered network model which can help you make a right choice. Basic Knowledge of Switch Before we come to the three-tiered network model, let’s learn about some basic knowledge of switch.
All switches maintain a media access control (MAC) address-to-port table which is used to intelligently forward frames out the right ports to the intended destinations. Three-Tiered Network Model We know that different types of switches have their own characteristics. Core Switch The most striking feature of core switch is speed. Distribution Switch The function of distribution switch is connecting the core and access tier together on the network. Access Switch Conclusion. Difference between 12-fiber and 24-fiber MTP/MPO. Since IEEE 802.3ba 40GBASE-SR4 and 100GBASE-SR10 were ratified in 2010, many have looked to 24-fiber connectivity as the ideal migration solution in the data center. Using 24-fiber cabling throughout an entire channel provides extra flexibility, as users can easily migrate from 10G to 40G or 100G by simply swapping out the connectivity at the end of the channel.
Pre-terminated cabling using 24-fiber connectors provides double the density of 12-fiber cabling in the same footprint, reducing the cabling required, allowing for fewer cable pathways, and improving airflow in data centers. With the growth of 24-fiber MPO/MTP solutions, some confusion and misinformation has emerged within industry circles. Especially, the differences between 12-fiber and 24-fiber MTP/MPO connectivity. 24-Fiber MTP/MPO Connectivity Is More Suitable for 100G than 12-Fiber The current IEEE 802.3ba 100GBASE-SR10 standard defines 100GbE using 10 lanes of multimode fiber at 10 Gb/s. Let’s look at another example. How to Choose Optical Distribution Frame - Fiber Optical Networking. Due to the development of high speed transmission, demands for high density patching have increased in recent years. However, the management of installed cables still remains a difficult task.
To achieve a simpler way of cable organization, people often use the cost-effective optical distribution frames (ODF) to arrange optical cable connections. ODF plays an important part in building a safe and flexible operation environment for optical network. Different kinds of ODFs are provided in the market, but you need to choose the right one according to actual situation. Functions of ODF ODF is mainly used for fiber optic terminal splicing, fiber optic connector installation, optical path adjusting, excess pigtail storage and fiber optic cable protection. Things to Consider for Choosing ODF Selecting a right ODF is vital to future applications. 1) ODF Types Generally, there are three types in terms of its structure. 2) Fiber Counts 3) Easy Management 4) Good Protection Conclusion. TP-Link T1700X-16TS Vs. T1700G-28TQ. Though 40G and 100G have been widely applied in big data center, 10G is still popular with small homelab.
Many 10G switches on the market are designed to used with SFP transceiver module and 10G SFP+ transceiver module, while TP-Link has two 10G switches—T1700X-16TS And T1700G-28TQ, which are respectively characterized by 10GBASE-T RJ45 ports or 10/100/1000Mbps RJ45 Ports. This article will make a comparison between them. Overview of TP-Link T1700X-16TS And T1700G-28TQ As members of TP-Link’s T1700 Series 10G smart switches, TP-Link T1700X-16TS And T1700G-28TQ are designed to provide increased scalability, higher bandwidth, and enhanced performance. Figure 1. Figure 2.
TP-Link T1700X-16TS Vs. Similarities Differences TP-Link T1700X-16TS is equipped with 12 x 10GBASE-T RJ45 ports and 4 x 10G SFP+ ports, providing 320 Gbps switching capacity. Conclusion From the above comparison, we can find that both TP-Link T1700X-16TS and TP-Link T1700G-28TQ have their own advantages. Data Center Architecture Designs Comparison: ToR Vs. EoR. The interconnection of switches and warranty of data communication are the basic aspects to consider when designing a data center architecture.
Today’s data centers have been shifted into 1RU and 2RU appliances, thus setting the 1RU and 2RU switches into the same-sized racks can greatly save space and reduce cabling demands. Typically, Top of Rack (ToR) and End of Row (EoR) are now the common infrastructure designs for data centers. In this article, we will mainly discuss the differences between these two approaches. Overview of ToR & EoR What Is ToR? ToR approach refers to the physical placement of network access switch in the top of a server rack. What Is EoR? In the EoR architecture, each server in individual racks are directly linked to a aggregation switch eliminating the use of individual switches in each rack.
Comparison Between ToR & EoR Benefits In the EoR, device count is decreased because not every rack should equip the switches. Limitations Physical Deployments of ToR & EoR. What Is the SFP or SFP+ MSA? - Fiber Optical Networking. A small form-factor pluggable (SFP) is a type of transceiver device that has been standardized by the MSA (multi-source agreement). The MSA will define the characteristics of the system and is typically an agreement between multiple manufacturers. The agreements guarantee that any SFP or SFP+ device from any vendor will function properly.
This article will give you a more comprehensive introduction to the SFP and SFP+ MSA. An Overview of Pluggable Optical Transceiver MSA Standards Both SFP and SFP+ optical transceivers are standardized by MSA. These documents strictly define sufficient characteristics of an optical transceiver so that system (like Ethernet switch, Router, and media converter) vendors may implement ports on their devices, therefore, MSA compliant pluggable optical transceivers (SFP or SFP+) from any vendor will function properly.
What is Defined by the MSA? The main elements defined in the SFP/SFP+ MSAs are listed as follows: Mechanical Interface Electrical Interface. 10GBASE-T Cabling Vs. 10G SFP+ Cabling in 2017. When it comes to 10G network, we usually make a choice between 10GBASE-T cabling and 10G SFP+ cabling. In fact, many people still prefer 10G SFP+ cabling that uses SFP+ DAC cable, because they think it matches better for the requirements and emerging trends of today’s data center. Now the 10G network is quickly becoming mainstream, especially on consumer desktop systems. That means the cost of 10GBase-T switches will need to come down. Also, other “IOT” home components that decide to offer 10G will probably go for 10GBASE-T, such as game consoles, streaming boxes, etc.
Vote for 10GBASE-T The 10GBASE-T ports are physically smaller which is important for non-data center devices. Vote for 10G SFP+ 10G SFP+ is better for future-proof cabling system. By comparison, we find that if flexibility and scalability are more important, 10GBASE-T cabling is a better option; but if power consumption and lower latency are critical, 10G SFP+ cabling may be more suitable. A Third Choice Conclusion. Do You Know About Fiber Optic Splitter? - Fiber Optical Networking.
In today’s optical network topologies, the advent of fiber optic splitter is significant in helping users maximum the performance of optical network circuits. Fiber optic splitter, or sometimes called as beam splitter, is a passive optical component that can split an incident light beam into two or more light beams, and vice versa. The device contains multiple input and output ends. Whenever the light transmission in a network needs to be divided, fiber optic splitter can be implemented for the convenience of network interconnections.
How Does Fiber Optic Splitter Work? As for the working principle of fiber optic splitter, it can be generally described in the following way. When the light signal transmits in a single-mode fiber, the light energy can not entirely concentrated in the fiber core. A small amount of energy will be spread through the cladding of fiber. Classification of Fiber Optic Splitter At present, there are two types of fiber optic splitters. Applications Conclusion. Guide to Build Up Home Network | Fiber Optic Networking.
