With newer configuration standards and better, sleeker designs, businesses who produce these items seem to be pumping them out weekly to help meet the demands of growing companies. From little SFP transceivers to older GBIC devices, each product attempts to help interface your server’s motherboard to the external communication network—the copper wiring or fiber optic—used to convey and receive information. Sure, there are a range of different modules for you to order from, but often, you can get away with ordering a product today that can serve your business’ needs for a few years before you need to actually upgrade.

Compatibility Today

Every module you purchase today will provide support for the multiple sorts of Ethernet standards that exist, from pre-10GE to 100GE, as well as for configuration across several wavelengths. When in the market for a new module, just make sure you think about your current and later needs, because Ethernet standards will change and newer, more efficient standards will make their way into the industry, making older ones obsolete. If you’re hoping to save a few bucks and purchase ...
... an older module, just make sure that the later ones lend support for newer standards that may soon take over as the norm. If you do decide to order a module, you might be pressed to get the Cisco GLC-T that supports all up to date standards and what looks to be the future—100GE—for added support.

Certified Warranty

The golden rule to purchasing a new or used device is getting one that comes with some insurance—a warranty—in case the day ever comes when it actually breaks. Regardless of the name brand associated with the module, 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. Say you don’t order a warranty and the item breaks; not only do you have to replace it, but you’re out anywhere from a few hundred to a thousand dollars.

Price Range

Every buyer 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 end up with the best deal.
