Here’s a frequently asked question to address questions that have arisen from the significant uptick in the use of 25G transceivers, which is driven by high bandwidth demands in the enterprise, data center and service provider applications. 1. Why is the use of 25G increasing? Many network operators have chosen 25G instead of multiple 10G’s because 25G provides 2.5x bandwidth of the 10G in the same familiar SFP form factor at approximately the same power. This has enabled network equipment manufacturers to provide higher bandwidth connectivity. Rack-mountable switches and routers populated with 12 ports, 24 ports, and 48 ports on a single 1 RU faceplate are common for SFP. 2. What is the cost per bit of 25G? 25G provides 2.5x the bandwidth of 10G at a slight increase in cost. The result is nearly a 50% reduction in the cost per bit. 3. Is 25G standardized? The IEEE (Institute of Electrical and Electronic Engineers) has standardized 25G. See IEEE802.3b...
