The 1000BASE-T1 SFP Module H-MTD is a solution to convert between 1000BASE-T1 and SGMII using an H-MTD connector. It ?ts into a standard SFP (Small Form-factor Pluggable) slot and provides an Automotive Ethernet interface (100/1000 Mbit/s full-duplex, on one single twisted pair cable). 
When plugged into approved devices, Hardware-in-Loop (HiL) systems, and test benches with compatible chassis, the SFP Module has to be configured to Automotive Ethernet after power-up.
1000BASE-T1 SFP Module H-MTD是一款通過H-MTD接插件實現1000BASE-T1和SGMII轉換的模塊，它適用于SFP插槽，并提供一路千兆車載以太網接口。當插入到允許的設備中，硬件在環系統，測試臺架中，SFP模塊需要在上電后對車載以太網進行配置。

The device features four dip switches for the following functionalities:
本設備有4個dip手動開關，可以實現如下功能

• Dip 1: Slave / Master主/從

• Dip 2: 100/1000Mbps百/千兆

• Dip 3: IEEE/Legacy mode

• Dip 4: SingleSendS/MultipleSendS mode 單/雙SendS模式

The device can be used together with other Technica Engineering products, like the Media Gateway?or the?Enhanced Ethernet Switch (EES)?, or other approved chassis of Technica partners. 
本設備可以與其它Technica Engineering的產品一起工作，比如MediaGateway, 或者Enhanced Ethernet Switch（EES）, 或Technica伙伴其它經過批準的設備
However, the SFP Modules do not work as a “plug-and-play” solution. To set up the SFP Module, the user must be able to interact with the registers of the Phy via I2C 
and get in touch with Marvell (the PHY manufacturer) to receive the NDA-protected PHY-register setting datasheet to initialize the Phy. 
Some commercially available devices already recognize and work with the SFP modules successfully, please check the supported devices together with us.
但是，本SFP模塊不是一個"插入即可使用"的設備，以調試SFP模塊，使用者需要通過I2C與寄存器進行交互，請聯系Marvell獲取NDA保護下的寄存器設置手冊以初始化Phy.
一些商用設備已經能識別并和本SFP模塊一起正常工作。請聯系我們確認是否支持。
