DSL vs Ethernet Cable vs Fiber Optic Cable Speed

Wifi is excellent, we all love it. But under the wireless work, there are serious cabling, and data travels through DSL, Ethernet cables and fiber optic cables. The question is, which one performs better? And what’s the difference between DSL, Ethernet cable and fiber optic cable speed? Don’t worry, we are here to help you understand the key differences among the different cables.


What Is DSL?
DSL stands for Digital Subscriber Line. It’s a communication medium used to deliver digital signals via the copper telephone lines. DSL service functions much like dial-up Internet service. However, unlike dial-up service, the “two-wire” technology of DSL makes it possible for users to connect to the broadband internet and make or receive phone calls at the same time. Because DSL utilizes the existing telephone lines which means there is no requirement for extra cabling for DSL service. Thus, it allows users to download files, watch online videos and support cloud backups.

What Is Ethernet Cable?
Ethernet cable is the most common network cable type in our daily life, which is specifically designed to facilitate the communication between different electronic equipment such as computers, fax machines or scanners. Cat3, Cat5, Cat5e, Cat6, Cat7 are the different Ethernet cable types. Each new promotion of category supports increasingly faster bandwidth speeds and improves upon the signal-to-noise ratio.

What Is Fiber Optic Cable?
The fiber optic cable contains strands of glass fibers inside an insulated casing. Compared with the wired cables, fiber optic cable speed is faster which is designed for long distance and high performance data networking. Single mode fiber and multimode fiber are the primary types of fiber optic cable. Both of them can support the world’s Internet, cable television and telephone system.

DSL vs Ethernet Cable vs Fiber Optic Cable Speed
When we buy the cables, the speed is always an important consideration. Now we’ll compare DSL, Ethernet cable and fiber optic cable speed.

DSL speed
Download speed of DSL is generally in the 1-35Mbps range, while the upload speed ranges from 1Mbps to 10Mbps. When the DSL packages speed is around 1 megabit per second, it’s suitable for basic web browsing and sending or receiving emails. If the cable speed is up to 6Mbps or 7Mbps, you can enjoy online music and standard video streaming but may be a little slow for HD video.

Ethernet Speed
Ethernet cable download speed usually starts from 10Mbps to 500Mbps, and the upload speed is 5-50Mbps. Note that these ranges are the criteria you can achieve for home use. And for the specific areas, internet providers offer much higher speed which can be 1000Mbps. With a faster data speed, you can enjoy HD audio streaming and VoIP services.

Fiber Optic Cable Speed
Fiber optic cable speed is the fastest. Download speed of a fiber patch cord could be anywhere from 250Mbps to 1000Mbps. And fiber providers commonly provide “symmetrical” service, which means the upload speed is as high as the download speed. Though fiber optic cable price is usually a bit higher than DSL or Ethernet cable, it’s always worth buying it. You are free to enjoy heavy web browsing, file sharing and online backup, superior download and upload. And it’s a great option for hosting servers and complex cloud-based services.

Conclusion
As described above, fiber optic cable speed definitely wins. If you want a connection that can move at lightning speeds, fiber is the best choice. If you care more about the budget, both DSL and Ethernet cable can offer plans that allow you to get a decent network speed at a reasonable price. DSL is for lower speed plans, while Ethernet cable is for higher speeds. So choose the best Internet cable service based on your needs.

How to Convert SFP to Ethernet?

SFP ports and RJ45 ports are the most common interfaces which are used in Gigabit Ethernet applications. And we complete the fiber to Ethernet or Ethernet to fiber conversion via these ports. How much do you know about SFP ports and RJ45 ports? And do you know how to convert SFP to Ethernet? This article will explain these questions.

What Are SFP Ports?
SFP ports are the input and output interfaces that are able to be hot-pluggable. They are seen in network switches or network interface cards. And SFP port is capable of working with the standards of 1000BASE-SX, 1000BASE-LX/LH, 1000BASE-ZX or 1000BASE- BX10-D/U.

At present, network switches are usually designed with two or more SFP ports, which comply with IEEE 802.3ab standard. Note that in all cases, the SFP transceiver module must be inserted then the SFP ports can work. The ports make it possible for Gigabit switches to connect to the fiber and copper cables, converting SFP to Ethernet or Ethernet to SFP and completing the switching function.

What Are RJ45 Ports?
RJ45 port, which stands for registered jack 45, is the ubiquitous Ethernet style data port seen on switches, routers and network cards, following the 1000BASE-T Ethernet standard. It only supports RJ45 cables like CAT5e, Cat6 with the transmission speed of 1Gbit/s. By far, the most common use of RJ45 port is with Ethernet data connections from computers network cards, wireless access points, network switches and routers in home and enterprises networks. RJ45 ports on a data switch use the built-in design. Connecting two RJ45 copper switches, we just need a Cat5e or Cat6 copper cables. But if we want to convert Ethernet to SFP, an RJ45 SFP transceiver is required.

FS Solutions to Convert SFP to Ethernet
From the above, we have a good understanding of SFP ports and RJ45 ports. They are the interfaces for converting SFP to Ethernet or Ethernet to SFP. But how? Here FS provides two solutions for you.

Solution 1: Using SFP Transceiver Module
As we have mentioned above, the network switches on the market are generally equipped with SFP ports. Thus, under this circumstance, we can use SFP modules to complete the interconnections between switches or servers. Insert the Ethernet SFP module into the network switches, then plug one end of Cat5e or Cat6 cables into the transceivers and the other end is connected with other terminal devices. This figure shows how we can use SFP transceiver for our conversion need.



We can see this is a full solution, covering the following equipment.



Solution 2: Using Ethernet Media Converters
If your switch doesn’t have SFP ports, then you need an Ethernet media converter. It’s a device used to interconnect fiber and copper cables to facilitate communication between them. This device looks like a small box where fiber and copper cables could be plugged in. Here is the SFP to Ethernet converter from FS.COM. It has one RJ45 port and one SFP port. And the mini converter can support 1000Base-X to 10/100/1000Base-T UTP convention. Designed with compact package size, it’s a reliable plug and play converter. Therefore, just plug the fiber and copper cables into the slots and connect the other ends of cables to the terminal devices, ensuring the whole network works properly.

Conclusion
Using SFP transceiver module or Ethernet media converter can help us convert SFP to Ethernet, which can better expand network function. FS.COM offers an extensive choice of full SFP to Ethernet or Ethernet to SFP solutions. Choose FS.COM for the right product to meet your conversion project needs.

What Is Ethernet Leaf Switch

At present, with the massive increase in data transmitting and the need for real time data travel within the network, Ethernet switching technology has evolved greatly over the last decade. As a result, the existing aging three-tier design has been replaced by the new leaf and spine architecture in data centers. This new network architecture requires specially designed leaf switch in order to work. So how much do you know about leaf switch? Here we’ll explain this data switch in this article.

Leaf Switch Introduction
As the figure1 shows, a leaf-spine architecture is usually composed of spine switches and leaf switches. Leaf switch is used to gather the traffic from the server nodes, then link to the network core that consists of spine switches. In this case, every leaf switch connects to every spine, which contributes to minimizing the network latency and bottlenecks. Therefore, the leaf and spine architecture allows for huge amounts of bandwidth and provides a high level of redundancy.



Figure 1: Leaf-Spine Architecture

Traditional Three-Tier VS Leaf-Spine Architecture
Commonly, a traditional model includes three layers, core, aggregation and access. And most data center services and functions run on physical hardware that drives “north-south” traffic. If there are some east-west traffic that needed to be transferred across the traditional model, devices connected on the same access layer contend for bandwidth. Therefore, congestion will be created between the access and aggregation layer.

Figure 2: Traditional Three-Tier Topology

Unlike the traditional three-tier, the access layer of leaf-spine structure is formed by each leaf switch that is directly connected to each spine switch. And this direct connection helps to minimize the traffic bottlenecks and latency, and utilize the networking protocols and methodologies to create a dynamic network.

Leaf-Spine Architecture Advantages
As described above, we know the advantage of leaf-spine model is the improved latency and reduced bottlenecks. With this new approach, only a few data switches are needed to create a large and non-blocking fabric. This is the main advantage that makes it popular in networking system.

In addition, leaf-spine uses all interconnection links. This means an additional spine switch could be added and the uplinks can be extended to each leaf switch, which can increase the interlayer bandwidth. Therefore, it allows the network to scale without managing or disrupting the Layer 2 switching protocols as the traffic grows.

Leaf Switch Recommendation
To keep pace with the market needs, FS.COM has produced S5850 series 10GbE switches for using as leaf switches, including three products. We’re going to see these three leaf switches.

These three leaf switches are made of the same robust materials. All of their airflow directions are front-back. From the table, we can see that all S5850 series products support MLAG, SNMP, SFLOW and son on. So you can choose one according to your demands.

Conclusion
Leaf switch and leaf-spine architecture make the network more flexible. And FS S5850 series data switches are the quite cost-efficient selections. FS provides a full line of network switches including 24 port switch, 48 port switch and 1G switch, 10GbE switch and 40GbE switch. Come and choose the suitable switch.

SFP Fiber Switch Introduction and Cabling Solutions

With the growth of today’s network, the amount of hardware involved has become a barrier to efficient and optimized network operations. In some cases, a fiber switch is the answer. These fiber switches with management functions can reduce the burden on the network backbone, by connecting different edge-level devices and combining them into a single data stream. Today, we’ll focus on SFP fiber switch and its cabling solutions.

SFP Fiber Switch Introduction
As the name implies, an SFP fiber switch is a communication control device with SFP ports. And like a common networking switch, SFP fiber switch is also used to send and receive data transmission, but in fiber channel. These SFP ports are small form-factor hot pluggable interfaces, so the SFP optical transceiver modules can be inserted into the SFP ports. Then the fiber cables can be used to connect the fiber switch to other networking equipment.

Advantages of SFP Fiber Switch
SFP fiber switch can provide a higher reliability and security than the RJ45 port switch. As we know, fiber cables transfer data in light, which is faster than the copper cables’ electronic transmission speed. And due to the special design of fibers, the SFP fiber switch generates less data loss and electromagnetic interference. Therefore, using an SFP fiber switch is better than the RJ45 port copper switch. For example, if the transmitting distance is more than 100 meters, copper cables like Cat5e or Cat6a is unable to reach. So you need the fiber cables which are often used to interconnect switches in multi-building deployments.
