• 25G SFP28 AOC: The Market and Trends

    In general, there are three ways of 25G access of server, namely DAC (Direct Attach Cable), optical transceiver and AOC(Active Optical Cable). DAC can reach no more than 5m, so it is difficult to meet the requirements of cross-rack wiring distance. The optical transceiver can reach up to 100m or more using multi-mode fiber, but the cost is high. AOC is an Active Optical Cable. AOC can reach up to 30m at a reasonable cost. Therefore, AOC cable is a good choice for cross-rack server access, which is more suitable for China’s current data center rack power and network architecture. Here’s some information about the 25G AOC that you may be wondering about. 25G AOC provides a cost-effective solution for those same data center applications that require longer distance interconnect using active optical Ethernet technology. There are some advantages to 25G AOC.

  • In Case You Missed the Questions for 25G Transceiver

    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 IEEE802.3by and IEEE802.3cc for the details. 4. Which popular Gigalight’s 25G transceivers are available today? 25G SFP28 SR 100mIndustrial 25G SFP28 LR 10km Industrial…
