10G電口模塊特點
l市場大多數數據中心內設備間的鏈路距離在10 m到80 m之間，使用10GBASE-T SFP+電口光模塊能彌補SFP+高速線纜傳輸距離的不足。
l10GBASE-T SFP+電口模塊采用RJ45接口，和超六類或七類網線一起使用，而銅纜布線的成本要比光纜布線的低。
l在成本上，10GBASE-T SFP+電口模塊可以直接用在現(xiàn)有的銅纜布線系統(tǒng)中實現(xiàn)10G傳輸，而使用SFP+光模塊則需要用光纜進行布線，這會增加部署成本。如果想要在現(xiàn)有銅纜布線系統(tǒng)中使用SFP+光模塊，則需要增加以太網交換機或光電轉換器等設備

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.
