In general, the cost of an original brand SFP module is more expensive than a 3rd party one. Take Cisco 1000BASE-SX SFP (GLC-SX-MMD) for example, the list price of Cisco is about $ 500.00, but you can easily find a 3rd party SFP modules that can take a discount at up to 90% off. As the cost of SFP...
