Fiber transceiver solution

With the increasing demand for better network, the data center devices need to be kept upgrading. To meet the requirement for easy-to-manage fiber cabling environments, FS has upgraded 4U FHD rack mount fiber optic enclosures. Well, what’s the difference between the upgraded 4U FHD fiber enclosure and the old one? This article will give a clear explanation for it. What Is Fiber Optic Enclosure?

To understand the difference between the upgraded 4U FHD fiber enclosure and the old one, we’d better get to know fiber optic enclosure first. Fiber optic enclosure, also called fiber spice box, refers to an empty box or a unit. It is a high-density equipment which is designed to house, organize, manage and protect fiber optic cables. It usually comes in rack units of 1U, 2U, 4U, or more rack units (U is short for rack unit and 1U equals 1.75 inches).


So fiber enclosures with different rack units have different fiber capacities. For instance, 1U fiber enclosure can support 96 fiber cables, while 2U fiber enclosure can support up to 192 fiber cables. Moreover, fiber optic enclosures come with different configurations for different deployment scenarios, including rack mount, wall mount enclosure, and indoor or outdoor enclosure.

FS recently develops a new type of 4U rack mount fiber optic enclosure. The upgraded 4U rack mount FHD fiber optic enclosure and the old one share most functions. For instance, they provide a modular system for managing fiber connections and support up 288 fibers capacity for LC interface. They can also house MTP modular cassettes or fiber adapter panels. Besides, both of them are made of SPCC (Black Coating). Then what’s their difference?

Rack mount fiber optic enclosures, as the important cable management element, are widely used in data centers. FS upgraded 4U rack mount FHD fiber optic enclosures offer the improved performance and are more convenient for network cable management. And each enclosure will be shipped with an accessory pack, including mounting screws, spools, bend radius bracket for proper installation and cable ties for cable management. Moreover, FS also provides reliable fiber cassette and fiber optic patch panel for your network. If you have any needs, please feel free to visit FS.COM.

Conventionally, 10GBASE-CX4 is suitable for the deployment of switch to switch and switch to server in a rack or same room. DAC cable is commonly employed in intra-rack and inter-rack connections, including interconnection of top-of-rack switches with servers and storage devices in ToR or adjacent racks. Due to the longer transmission distance, 10GBASE-SR can be used in large buildings, enterprise wiring closet, and service provider transport applications. 10GBASE-CX4 vs DAC Cable vs 10GBASE-SR: Which Is the Best Option for 10G Network in Short Reach?

10GBASE-CX4 is an early favorite for 10G network, but it is now outdated due to its relatively large connector and high price. DAC cable costs less and consumes less power than 10GBASE-SR, but it reaches only up to 15 m. You can choose the DAC cable if your switch in the same rack. 10GBASE-SR has the longest transmission distance (up to 400 m) among them and it can provide a smaller cable profile and flexibility in the placement of servers. As mentioned above, 10GBASE-SR is the most expensive solution. Fortunately, the booming of the third party reduces the price of it. All in all, since the demand for bandwidth and link length is not gonna slack, 10GBASE-SR may be the best option for short connections. Conclusion

10GBASE-CX4 vs DAC cable vs 10GBASE-SR: which is the best option for 10G network in short reach? You might already get the answer. When you choosing 10 GbE transceivers for short reach in the market, you can refer to the comparison in this article. And FS provides various cables and transceivers with high quality.

The managed switch is a device that can be configured. It is designed with diverse advanced features such as VLAN, SNMP, CLI, IP routing, QoS, etc. Therefore, this manageable switch is usually used in the core layer of a network to offer the most comprehensive functions. What’s more, managed gigabit switches are available in two types: fully managed switches and smart switches.

Fully managed switches are usually employed in large enterprise or complex data center, offering all capabilities of the managed switch. When users want low cost and do not need so many features of the managed switch, the smart managed switch is an optimal choice. It has a limited number of options for configuration and is ideal for home or office use. As shown in the figure below, FS S3900-24T4S fanless switch has an advanced feature set that brings robust multicast control, high availability, security and simple management. It is also a stack switch and is easy to be employed in the home, SMB and schools with a cheap price.

Conventionally, the unmanaged switch is used for home. However, as a plug & play switch, it has limited performance and doesn’t support any configuration interface or options. With more requirements of home users, the managed switch gets more popular for home. There are three main advantages of choosing the managed switch for home network.

Security and resilience – Managed switches deliver the most precise control of data, bandwidth and traffic control. And additional firewall rules can be set up into it directly. Therefore, the managed switch can provide good protection of the data plane, control plane, and management plane.

Redundancy – Redundancy means a back up data path to network traffic to safeguard the network when a connection or cable fails. The managed switch can incorporate Spanning Tree Protocol (STP) to provide path redundancy in the Ethernet network. And this also prevents loops which are created by multiple active paths between switches.

Prioritize bandwidth for data subsets – The managed switch can prioritize one type of traffic over another. This enables more bandwidth to be contributed through the network. Therefore, this function brings higher network performance and better transmission of delay-sensitive data. How to Choose Managed Switch for Home?

Features and performance – As mentioned above, the managed switch has many features. There is no need for you to select a managed switch with all features for home. Except for the basic features such as advanced QoS, VLAN, security, etc, you’d better take switching capacity, max power consumption, continuous availability into consideration. Beside, fanless and stack designs are important factors as well. Fanless design help reduce the power consumption and stack design can save the place makes.

Switch ports – The managed switch often comes with copper or optical ports, PoE or PoE+ ports, and a console port. Usually, there are three types of ports on a managed switch. The copper port can connect with Cat5e or Cat6. Compared with the copper port switch, the switch with optical port connects with fiber transceivers and optic cables to uplink to the backbone switch for longer transmission. PoE or PoE+ ports are designed for home IP camera systems, or for situations where there is no power source for PoE enabled devices. The count of the main ports often come with 8, 24 or 48. Besides, the 8-port and 24-port managed switches are commonly used for home. You can choose a suitable one based on your need.

Costs – The cost of copper port switch is lower than that of the optical port switch. What’s more, devices connected with copper port like Cat5e or Cat6 are cheaper than the device needed by the optical port including transceiver and fiber patch cable. When you already have determined the type of managed switch you want, you can compare the price from different companies. Usually, managed switches from famous brands are expensive. If you have limited costs, you can choose managed switches from other reliable firms. All in all, cost-effective product is a better choice. Conclusion

The best network switch is the one that suits your network most. When you buying a managed switch for home, remember to consider the factors mentioned above. FS provides various managed switches with high-quality and high performance. If you have any needs, welcome to visit FS.COM.

With the increasing diversity of network applications and the implementation of some converted networks, the multilayer switch is thriving in data centers and networks. It is regarded as a technology to enhance the network routing performance on LANs. This article will give a clear explanation for multilayer switch and how to use it. What Is a Multilayer Switch?

The multilayer switch (MLS) has 10gbe switch and Gigabit Ethernet switch. It is a network device which enables operation at multiple layers of the OSI model. By the way, the OSI model is a reference model for describing network communications. It has seven layers, including the physical layer (layer 1), data link layer (layer 2), network layer (layer 3) and so on. The multilayer switch performs functions up to almost application Layer (layer 7). For instance, it can do the context based access control, which is a feature of layer 7. Unlike the traditional switches, multilayer switches also can bear the functions of routers at incredibly fast speeds. In addition, the Layer 3 switch is one type of multilayer switches and is very commonly used.
