SFP28 25G 30AWG-2P

The SFP28 25G is primarily used for interconnecting data center servers and switches and is a new Ethernet standard with multiple advantages The biggest advantage that 25G Ethernet technology brings to the data center is the ability to maximize bandwidth and port density, and it can also achieve 100Gb data transmission using 25Gbs single-channel physical layer technology
