Which to Choose Among S3900 Series Gigabit Ethernet Switch?

When it comes to choosing from FS.COM S3900 Gigabit Ethernet switch, you need to consider the number and type of ports you need and whether the switch is fanless or with fans.

What are the Port Type and Port Number You Need?

FS.COM S3900 series Gigabit Ethernet switches offer three different port combination options. You can choose from them according to your network demands.

If you need 24 port Gigabit switch, both S3900-24T4S switch with 24 10/100/1000BASE-T ports and S3900-24F4S switch with 24 SFP ports are within the scope of consideration. Then which to choose between S3900-24T4S switch and S3900-24F4S switch? It depends on your need. If cost, backward compatibility with legacy copper cabling networks, power consumption are important for you, S3900-24T4S switch with 24 10/100/1000BASE-T ports is the better choice. If you prefer lower latency and switches with combo SFP ports then you could consider S3900-24F4S switch with 24 SFP ports which contain 4 combo ports. To make it clear, a combo port is both a copper port and an SFP port sharing the same switching fabric and ID but connect to different transmission media. The two ports can’t be at the same time. When either of the two ports is enabled, the other port is automatically disabled. It gives users the options and flexibility to configure their switch for their unique application requirements.

Besides, the S3900-24T4S switch with copper ports is connected with Ethernet cables with the transmission distance of no more than 100m. While the S3900-24F4S switch with SFP ports is connected with SFP fiber optic transceiver modules & fiber patch cables with the transmission distance of 550m to 150km. So, S3900-24F4S switch is more suitable for long distance transmission, while S3900-24T4S switch is more suitable for short distance transmission.

If the network devices you are going to connect are of large amount, and you have a relatively big network, then you need to choose a switch with more than 24 ports. The S3900-48T4S switch with 48 10/100/1000BASE-T ports can satisfy your demand. It has the switching capacity of 176Gbps, which is the largest among the S3900 series switches.

Fanless Switch or Switch With Fan?

If you are planning to use the switch in quiet space, like offices, home, shops, libraries, hospitals or clinics where noise can be an issue, FS.COM S3900-24T4S fanless switch is recommended. Fanless switches are equipped with a passive cooling system, which has the advantage of energy efficiency and lower financial cost. The switches with fans are mostly deployed in data centers which have separate data center rooms. While fanless switches are more suitable for small business, people working at home, and places where silence is needed.

SFP vs RJ45 vs GBIC: When to Choose Which?

SFP, RJ45, and GBIC transceiver modules are three main kinds of 1GbE transceiver modules on the market. You may be puzzled by so many choices of transceiver modules. Don’t worry about it. This article will help you clarify the differences among SFP vs RJ45 vs GBIC transceivers and give you some suggestions about how to choose from them.

What Is an SFP Transceiver?

Short for small form-factor pluggable, an SFP module is a kind of fiber optic transceiver module with LC duplex interface. It supports the transmission data rate of 1GbE. SFP optical transceivers can operate on single mode or multimode fiber patch cables. The transmission distance of SFP modules ranges from 550m to 150km.

Figure1: SFP transceiver module

What Is an RJ45 Transceiver?

SFP copper RJ45 transceiver is a kind of transceiver with copper RJ45 interface. SFP copper RJ45 transceiver modules can support the transmission data rate of 1GbE. They are often used with Cat5 cables. SFP copper RJ45 transceivers are popular to be used for short distance transmission, because the overall cost of the copper network is lower compared with the optical network.

SFP vs RJ45 vs GBIC: When to Choose Which?

As is shown in the chart, SFP, SFP copper RJ45, and GBIC transceiver modules are all used in 1Gbit data transmission. Then when to choose which for the 1GbE network?

When to Choose SFP Transceivers?

Compared with GBIC transceiver modules, SFP modules have a smaller size. So SFP modules allow having more interfaces on a line card or a switch. Besides, SFP transceivers can support the transmission distance much longer than SFP copper RJ45 transceivers and GBIC transceivers. So if you require long transmission distance,  SFP transceivers can meet your need. Last but not least, If you already have a line card or a switch with empty SFP slots, then you need to adapt to that.

When to Choose SFP Copper RJ45 Transceivers?

When your budget is not enough to use SFP transceivers, you can choose SFP copper RJ45 transceivers for short-distance transmission. If you have the requirement of long-distance transmission afterward, you can use SFP to RJ45 slot media converters. For they can provide an economical path to extend the distance of an existing network with fiber cabling.

When to Choose GBIC Transceivers?

If you already have a line card or a switch with unoccupied GBIC slots, then you need to choose GBIC transceivers to make full use of the empty slots on your switch. In fact, GBIC transceiver modules are gradually replaced by SFP modules on the market. For SFP transceivers are regarded as the upgraded version of GBIC modules.

Summary

The differences among SFP vs RJ45 vs GBIC transceiver modules include the interface type, transmission distance, and cable type. Your choice among them depends on different situations. If you want to buy Cisco SFP modules or other transceiver modules with high quality and low cost, please contact us at sales@fs.com.

Switch Definition In Networking Explained

When it comes to networking technology, we won’t miss Ethernet switches. Because it is an essential part of networking communication. Connecting devices, such as computers, routers, and servers, together on a network, it enables current to be turned on and off and selects a channel for data transmission. Then you may ask, what is the switch definition in networking? What are the types of switches in networking? How to choose a switch for my network? Now, this passage will give you the answers and suggestions.

What Is the Switch Definition In Networking

There is one question that confuses many people: what is a switch in networking? A switch, in the switch definition of networking, is a high-speed network equipment used to connect devices together on a network and enable the data transmission between different devices. It receives incoming data packets and redirects them to their destination on a local area network (LAN).

In a local area network (LAN) using Ethernet, a network switch determines where to send each incoming message frame according to the physical device address. This kind of address is also known as the Media Access Control address or MAC address. If a switch needs to forward a frame to a MAC address that is unknown by the switch, then the frame is flooded to all ports in the switching domain. Generally speaking, a data switch can create an electronic tunnel between the source and the destination ports that no other traffic can enter for a short time.

Switch Definition In Networking: Types of Switches In Networking

The Ethernet switch is an essential part of any network. Generally speaking, the Ethernet switch can be classified into two categories: the modular switch and the fixed switch.

Modular Switch

The modular switch has expansion ability and high flexibility. Modular switch makes it possible for you to add expansion modules as needed into the switches. It is much more complex than fixed switch, so it costs more than fixed switch.

Fixed Switch

The fixed switch isn’t expandable and has a fixed number of ports. Although it has less flexibility, it offers a lower entry cost. There are mainly three types of fixed switches in networking. They are the unmanaged switch, the smart switch, and the managed switch.

Unmanaged Switch

The unmanaged switch is often used in home networks, small business offices or shops. It can’t be managed, so we can’t enable or disable interfaces of it. Although it doesn’t provide security features, it can offer enough support if you use it in a small network of fewer than 5-10 computers.

Smart Switch

The smart switch is mainly used for business applications such as smaller networks and VoIP. It is suitable for small VLANs, VoIP phones, and labs. Smart switch can let you configure ports and set up virtual networks, but doesn’t have the ability to allow troubleshooting, monitoring, remote-accessing to manage network issues.

Managed Switch

The managed switch is widely used in data centers and enterprise networks. It provides control, high-levels of network security, and management. It’s ideal for remote-access control capabilities and off-site round-the-clock monitoring. The managed switches can improve a network’s resource utilization and speed. Although it costs the most, it worth the investment for a long run.

How to Choose a Switch For Your Network?

When you choose a switch for your network, you need to consider several factors at the same time. These factors include the number of ports, transmission speed, and stackable vs standalone.

Number of Ports

Most of the switches on the market have 4 to 48ports. You need to consider the number of ports you’ll need according to the number of users and devices and devices your network supports. The larger your organization is, the more ports you’ll need. Considering the possible expansion of your network and the possible increase of your user amount, you need to prepare extra ports for a long term plan.

Speed

There are various switches with different speed, such as Gigabit Ethernet switch and 10GbE switch used at the edge of the network, as well as 40GbE switch and 100GbE switch used in the network core layers. When you determine the speed, the key factor to consider is the need of your network users and future growth. Such as how large are the volumes of the transferring data and whether do you require faster link.

Stackable vs Standalone

Will your network grow larger? If your answer is yes, then you may choose a stackable switch. Standalone switches need to be configured individually, and troubleshooting also needs to be handled on an individual basis. While stackable switches allow for multiple switches to be configured as one entity. With this advantage, you can save time and energy when you manage on the stackable switches. Here I want to recommend you FS.COM S3800 switches, which are stackable switches. The following video is a tutorial about how to stack switches using S3800 switches.

Summary

In the above passage, we’ve explained how people define switch in networking and analyze the types of switches. Besides, this article offers some suggestions about how to choose a switch for your network. I believe that you have got a general idea about switch definition in networking.
