10GBASE-T is a standard technology that enables 10 Gigabit Ethernet operations over balanced twisted-pair copper cable, including Category 6a unshielded and shielded cabling. Compare with 10G optical transmission, 10GBASE-T uses copper cables, which offers great savings and flexibility during network deployment. And 10GBASE-T SFP+ copper RJ-45 transceiver, which is known for its reliability and good performance, provides data center managers a new option for their 10G networks. This article intends to give a detailed description about 10GBASE-T SFP+ copper modules.
The 10GBASE-T SFP+ copper transceiver is a high performance integrated duplex data link for bi-directional communication over copper cable. It is specifically designed for high speed communication links that require 10 Gigabit Ethernet over Cat 6a and Cat 7 cable. This is the first SFP+ transceiver that offers 10Gb/s communication over copper cables. In addition, this copper transceiver supports links up to 30 m using Cat 6a/7 cable, and is compliant with SFF-8431 and SFF-8432 MSA.
The most important point is that the 10GBASE-T SFP+ transceiver module can save at least 0.5W per port compared to an embedded 10GBASE-T RJ45 port for link distances up to 30 m, which makes it work better in port-by-port and rack-by-rack connections. Its RJ-45 connector supports shielded and unshielded cables. And it is mechanically robust enough and can prevent link loss when the cable is positioned or moves in different angles. With the RJ-45 interface, network operators can extend the life of switches hardware, without changing the existing infrastructures. And they also can upgrade to 10G networks easily.
As has mentioned above, SFP+ DAC, SFP+ optical transceiver and 10GBASE-T SFP+ copper transceiver are three components used in 10G connections. Here is a simple table showing the basic information about them.
Notes: the price of the three products comes from FS.COM. All of them are compatible with Cisco. The SFP+ DAC is ONS-SC+-10G-CU7 and the SFP+ optical transceiver is SFP-10G-SR.
From the chart, we can see SFP+ optical transceiver supports over 100m links and the supporting distance of SFP+ DAC is up to 7m. As this transceiver is used over copper cables, the power consumption is higher than SFP+ twinax DACs and SFP+ optical transceivers. And its price is 388 dollars, which is also higher than the other two components. Then some people may ask: with the available cheap SFP+ DAC and SFP+ optical modules, why 10GBASE-T SFP+ copper transceiver is needed?
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 SFP+ copper 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, 10GBASE-T SFP+ copper transceiver has the benefits over SFP+ solutions. Because copper-based infrastructure is far less expensive than fiber optics.
Finally, 10GBASE-T SFP+ copper transceiver is convenient for operators to deploy their network systems. When connecting 10G modules to copper networks, 10GBASE-T SFP+ copper transceiver can be directly added into the copper networks, while the 10G SFP+ transceiver needs to connect with Ethernet switch or media converter to realize this connection.
The 10GBASE-T SFP+ copper transceiver can offer the flexibility to deliver 10Gbps data over copper cables while providing a 10G data transmission to equipment with copper interfaces. The following pictures show two scenarios of it.
By using the existing SFP+ port for copper transmission, 10GBASE-T SFP+ copper transceiver offers greater flexibility for low density 10G copper applications than a fixed-port 10G switch. FS.COM recently launches several 10GBASE-T SFP+ copper transceivers which are compliant with brands like Cisco, Arista and Dell.
