Why Choose 10G Copper SFP+ for 10G Ethernet
Although fiber cable has a longer reach and reduced electromagnetic interference, the copper network cable is still popular for its reliability and cost-effectiveness. This is also true in the 10GbE network. 10GBASE-T copper SFP and SFP+ are two kinds of physical media for the 10GbE network. Here is the comparison between 10gbe sfp+ vs 10gbase-t:
10GBASE-T vs 10gbe SFP+: Backward Compatibility
10GBASE-T is an interoperable, standards-based technology, which uses legacy RJ45 connector and can auto-negotiate between 1 and 10-gigabit speeds. In other words, 10GBASE-T copper cabling is backward compatible with legacy networks. So we can deploy 10GBASE-T copper network now and start using it to connect with existing 1G ports or upgraded 10G ports.
10GBASE-T vs 10gbe SFP+: Lower Cost
The 10GBASE-T copper network usually uses Cat6 cable for cabling. And Cat6 cables are often less expensive than comparable length fiber cables. In the data center, with hundreds of required cables, this can turn into big savings. Further more, Cat6 cable is also cheaper than SFP+ 10G copper cable. And it can support longer transmission distance. In addition, the 10GBASE-T copper network can maximize the utilization of existing copper structured cabling. This will also save much capital expenditure.
Conclusion
As its price and power consumption continue to drop down, 10gbe sfp+ vs 10gbase-t, 10GBASE-T copper solution is much more popular than SFP+ in 10Gbps rack-based data centers that use ToR (Top of Rack) switches. If you want a flexible and cost-effective 10GbE network, 10GBASE-T copper solutions are ideal for you.
