Is the GLC-SX-MM Transceiver Right for Your Switch?



Growing businesses have growing networks. It's an unavoidable side-effect of expansion and maturation in a company. If you've hit the point you've begun to consider purchasing a large property, or opening up a second office, you may start running into the limitations of last decade's technology. Standard base-T100 Ethernet is fine for a small office, but it isn't sufficient to handle heavier network use. As your network expands, you might experience problems like:


  • Dropouts in your VoIP calls,
  • Sluggish data retrieval speeds,
  • Spotty WiFi coverage across a large areas,
  • Difficulty leveraging Cloud-based applications,
  • Or poor video streaming quality.


If any of this sounds familiar, it may be time to start thinking about an upgrade to gigabit Ethernet, which moves at ten times the speed of traditional Ethernet.

Issues When Considering Gigabit Ethernet in Your Growing Office


There are, of course, a number of issues involved in a major network infrastructure upgrade – but it's going to happen sooner or later as you continue to grow.


When contemplating a move to gigabit Ethernet, one of the most immediate concerns people have is how much new hardware they'll have to purchase. The good news is that one of the basic issues – providing connectivity at all – is generally quite easy.


If you've purchased your networking equipment in the last few years, it should have some industry-standard SFP ports, based on a Cisco standard. These inexpensive Small Form-factor Pluggable slots allow transceivers like the GLC-SX-MM to be plugged in and provide instant gigabit Ethernet connectivity.


Twisted Copper VS Fiber Optic Gigabit Ethernet


Another major consideration is whether you want to continue using copper-wire cabling or upgrade to fiber optic cabling in your offices. It's more expensive, but fiber optic provides several advantages over copper, while still providing the same gigabit speeds.

  • Fiber optic supports far longer cable lengths than twisted copper. Copper can only run for around 100 meters, whereas fiber can go between 200 and 500 feet, or more, without signal loss.
  • Fiber has given off no radio interference, allowing it to coexist more easily in an office with a lot of wireless devices.
  • Because of the lack of interference, fiber is also harder to hack into than copper.
  • Just as with copper, a standard GLC-SX-MM transceiver links fiber optic Ethernet with your existing equipment.


If you're looking towards the future, moving away from copper is probably a good idea. Fiber optics are growing steadily in popularity among businesses which have taken over large twisted-copper office buildings, created expansive complexes, or need to collaborate with remote offices in real time.


Using a GLC-SX-MM Transceiver to Connect Fiber Optic Gigabit Ethernet


The biggest advantage of Cisco's SFP system is that it's entirely hot-swappable. It doesn't matter what the device is, from servers to your switch to simple Ethernet cards: If it has an SFP port on it, it can support a multitude of transceivers for different functions, through one standardized interface. In fact, that standardization means that third parties can produce transceivers which are as good as official Cisco units.


Cisco even maintains a Compatibility Matrix, to help you pick the right transceiver for the job.


So, if you decide that fiber optic gigabit Ethernet is what you need for your future business communications needs, the GLC-SX-MM transceiver is truly simple to install and use. Simply plug it into your switch or other device, plug in the new network cable, and it should recognize the network in a few moments.


There are several different gigabit Ethernet standards out there, so do your research and see which best fits your vision for the future of your business. Just keep in mind that you'll need transceivers like the GLC-SX-MM to connect your existing devices to the new network.
