SFP+ Copper transceiver/ SFP+-T/ 10G SFP-T
Why Is a 10GBASE-T SFP+ Copper Transceiver Module Needed?
From what we have discussed, we can see that the power consumption of 10GBASE-T SFP+ Copper module is higher than 10G SFP+ Copper cable and SFP+ optical transceiver. And its price is also higher than the other two components. But with the available cheap SFP+ DAC and reliable SFP+ fiber optics available for 10Gbps application, why should people use the 10gb SFP+ copper transceiver modules?
Firstly, in data centers like the enterprise system, the length of the vast majority of links lies between 10 meters and 100 meters. The 10GBASE-T transceiver which provides 10Gb/s of data transmission over distance of 30 meters implements the limitation of SFP+ DAC. Secondly, with the common RJ-45 connector, 10G copper sfp module has the benefits over SFP+ solutions. Because copper-based infrastructure is far less expensive than fiber optics. Thirdly, 10GBASE-T SFP+ copper transceiver is convenient for operators to deploy their network systems. When connecting 10G modules to copper networks, RJ45 10GBASE-T SFP+ copper transceiver can be directly added into the copper networks, while the 10G SFP+ optical fiber transceiver needs to connect with Ethernet switch or media converter to realize this connection.
It is true that 10GBASE-T Cat 6a/7 cabling can provide limited support of 10GBASE-T in some environments, but the reality is that there are several compelling reasons to specify SFP+ 10GBASE-T copper modules in a new 10 Gbps-ready data center:
Smaller Form Factor: Interoperable with any SFP+ cage and connector system
Reliability: The RJ45 connector interface is rock solid. No surprises when deployed in your data center
Reach: Up to 30 m over Cat 6a UTP cable, sufficient for all network access use cases
Innovation: Hot-pluggable with a managed soft-start
Performance: Full PHY presentation, which means nothing is missing
Cost: Pay-as-you-grow model that performs for today and scales for tomorrow
