10G电口模块特点
l市场大多数数据中心内设备间的链路距离在10 m到80 m之间，使用10GBASE-T SFP+电口光模块能弥补SFP+高速线缆传输距离的不足。
l10GBASE-T SFP+电口模块采用RJ45接口，和超六类或七类网线一起使用，而铜缆布线的成本要比光缆布线的低。
l在成本上，10GBASE-T SFP+电口模块可以直接用在现有的铜缆布线系统中实现10G传输，而使用SFP+光模块则需要用光缆进行布线，这会增加部署成本。如果想要在现有铜缆布线系统中使用SFP+光模块，则需要增加以太网交换机或光电转换器等设备

PRODUCT DESCRIPTION
SFP+-10GBASE-T Copper Small Form Pluggable (SFP) transceivers are based on the SFP Multi Source Agreement (MSA) . They are compatible with the 10Gbase-T / 5Gbase-T / 2.5Gbase-T / 1000base-T standards as specified in IEEE Std 802.3 . SFP+-10GBASE-T uses the SFP's RX_LOS pin for link indication. If pull up SFP's TX_DISABLE pin, PHY IC be reset.
+3.3V Volt Electrical Power Interface
The SFP+-10GBASE-T has an input voltage range of 3.3 V +/- 5%. The 4V maximum voltage is not allowed for continuous operation.
