What Features Does Cisco Switches Have That Are not Addressed by Ubiquiti?
Cisco—Solid brand and construction
    • Solid software packages
    • Very ala Carte on their service and components.
    • Requires Prior knowledge of Cisco Networking. And configuration help from Cisco.
    • Most will feed a good sized area but you have to configure for overlap.
    • the controller is a small rack mount box and should be in your data center.
    • Simple management
Figure 3 shows the network plug-n-play with Cisco APIC-EM.
What Are the Tempting Points of Unifi Switches, Except Costs?
Ubiquiti—Good Brand and construction
    • Good software and easy to understand
    • No extra fees other than buying equipment
    • If you can program a home router you can set this unit up and the guest network with ease.
    • The controller is software based and easy to install and move should the original crap out or need to be reworked.
    • You can feed a good size office off of 2 of the Long-Range APs. the controller will handle the overlap for you.
How to Make a Choice Between Ubiquiti and Cisco Switches?
Cost: Price is the biggest incentive in most of the case. A general quote for ubiquiti and Cisco, the Cisco is typically 3 times the cost of ubiquiti. Considering the cost differences between Unifi and Cisco catalyst switches, what makes Cisco so pricey. According to many fiber optic technicians, the ubiquiti system will give them 99% uptime while the Cisco system will give them 99.99% uptime.
Performance: Except the budget, another thing to add into the account is going to be bugs in the code/hardware failures. Within the telecommunication industry, you are not going to find much better, as far as stability is concerned, than Cisco.
Support: With Cisco, you will get some of the best support in the industry. Ubiquiti Unifi switches are quite easy to install and manage. Their controllers are software based, which are quite easy to work with.
Together, If your require a more secure, more robust solution to meet your enterprise and complexity needs, then Cisco is your best option. If you are small to medium sized company and are not trying to create a holo projection of the wheel at every desk. Ubiquiti will be a great fit and should more than meet your needs.

FS.COM S2800 LAN access switch
Figure 4 shows the S2800 (24*100/1000Base-T+4*GE Combo) switches.
Although there is exact answer to this question, I Insist that you ask several questions inner your mind before taking the next leap.
Q1: Is what case would you absolutely need Cisco and Ubiquiti wouldn't do the job?
Q2: What features does Cisco products have that are not addressed by Ubiquiti?
Q3: Is this the best solution for me? Can I use other branded switches like FS.COM?

Four Basic Elements in a WDM System

We know that fiber can carry more data over long distances than any other physical medium. That makes fiber a very precious material. And how to make the most use of your fiber plant becomes a question. So there comes Wavelength Division Multiplexing (WDM).
Why Should We Deploy WDM ?
WDM can multiply your fiber capacity by creating virtual fibers. The foundation of WDM lies in the ability to send different data types over fiber networks in the form of light. By allowing different light channels, each with a unique wavelength, to be sent simultaneously over an optical fiber network, a single virtual fiber network is created. Instead of using multiple fibers for each and every service, a single fiber can be shared for several services. In this way WDM increases the bandwidth and maximizes the usefulness of fiber. Since fiber rental or purchase accounts for a large share of networking costs, substantial costs can be saved through the application of WDM. Next I will introduce to you the basic four elements in the form of a WDM system.
The Core Technology of WDM System
Generally speaking, a WDM system consists of four elements, that are transceiver, multiplexer, patch cord and dark fiber. The following text will explain them to you respectively.
optical multiplexer
  • Fiber Optic Transceivers. Optical transceivers are wavelength-specific lasers that convert data signals from SAN or WAN to optical signals that can be transmitted into the fiber. Each data stream is converted into a signal with a light wavelength that is an unique color. Due to the physical properties of light, channels cannot interfere with each other. Therefore, all WDM wavelengths are independent. Creating virtual fiber channels in this way can reduce the number of fibers required. It also allows new channels to be connected as needed, without disrupting the existing traffic services.
  • Optical Multiplexers. The WDM multiplexer, sometimes referred to as the Mux, is the key to optimizing, or maximizing, the use of the fiber. The multiplexer is at the heart of the operation, gathering all the data streams together to be transported simultaneously over a single fiber. At the other end of the fiber the streams are demultiplexed and separated into different channels again.
  • Patch cord. The transceiver transmits the high-speed data protocols on narrow band wavelengths while the multiplexer is at the heart of the operation. The patch cable is the glue that joins these two key elements together. LC fiber patch cables are popular, which connect the output of the transceiver to the input on the multiplexer.
  • Dark fiber. A requisite for any WDM solution is access to a dark fiber network. The most common way of transporting optical traffic over an architecture is by using a fiber pair. One of the fibers is used for transmitting the data and the other is used for receiving the data. This allows the maximum amount of traffic to be transported. At times only a single fiber is available. Because different light colors travel on different wavelengths, a WDM system can be built regardless. One wavelength is used to send data and a second one to receive it.
WDM has revolutionized the cost of network transport. Thanks to WDM, fiber networks can carry multiple Terabits of data per second over thousands of kilometers with a low cost that is unimaginable less than a decade ago. At FS, we offer a comprehensive portfolio of WDM transmission modules to support the network applications of enterprise and service provider customers. For more details, please visit
