Buying an SFP Module? Here’s What to Look for
Compatibility Today
Every module today comes compatible with both fiber optics and copper wiring, but they also are accessible to the Ethernet standards your business may use, such as 10GE and 100GE as well as earlier versions such as gigabit Ethernet. When in the market for a new device, just make sure you think about your present and later needs, because Ethernet standards will change and newer, more efficient standards will make their way into the industry, making older devices obsolete. If you decide to buy an earlier module to save a few bucks, just be certain it supports the newer standards as well as the earlier ones to make sure you get a wonderful bargain. For example, Cisco GLC-T transceivers support all the up to date and prior standards, making these excellent bargains for anyone looking for an upgrade or just a replacement.
Certified Warranty
If you do decide to buy a new item or even a used one, get it with a warranty to ensure your transceiver will not be one huge wasted investment if the day comes that it malfunctions. Regardless of the name brand associated with the product, they all will endure the wear-and-tear of daily use, and it's always good to end up purchasing a guarantee rather than being caught without one. Sure, you may wind up shelling out a bit more just to get the warranty with your module, but what's worse is being without one when the product breaks.
Price Range
Every shopper has an ideal range of amounts he would like to pay for a module; some people are willing to pay a bit extra for the additional features while others refuse to shell out cash for add-ons that may not even be helpful to the company. When purchasing new SFP transceiver modules, always make sure the price looks reasonably close to those of competitors so that you wind up with the best deal.
