MOD_ABS引脚一般是在模块的EEPROM内部存储器中定义的一个引脚,用于提供关于模块类型和功能的详细信息。通过读取这个引脚的状态,我们可以获取模块的型号、生产厂商、支持的传输速率等信息,从而可以准确地了解模块的性能和功能。这对于网络通信和数据传输领域的管理和控制是非常重要的。 综上所述,SFP模块的引脚定义在网络...
对于SFP+模块中的一些低速率管脚包括Tx_Fault、Tx_Disable、RS0/1、Mod_ABS、Rx_LOS在默认状态下都推荐使用4.7K-10K的电阻上拉到VCC,当然如若RS0-1选择较低速率模式,需要通过大于30Kohm的电阻下拉到VeeR。 ESD静电防护特性上SFP+光模块能够满足EN61000-4-2类型的ESD要求,自带ESD静电防护的话,对于做高速电路板...
MOD_ABS pulls line low to indicate module is plugged in. 5.Internally pulled down per SFF-8431 Rev 4.1. 6.LOS is open collector output. It should be pulled up with 4.7kΩ – 10kΩ on host board to a voltage between 2.0V and 3.6V. Logic 0 indicates normal operation; logic 1 ...
which allows the host system to discover which SFP modules are connected what are their capabilities. In addition, if the SFP modules contains an embedded PHY, it is also accessible through the same I2C bus.

[2]。应该停在4.7 k - 10 k欧姆主机板3.15湖3.6 v之间的电压。[3]Tx_Disable输入接触4.7 kΩ10 kΩ引体向上VccT内部模块。[4]Mod_ABS连接到VeeT或转向SFP +模块。主机可能把这个联系Vcc_Host电阻器在4.7 kΩ出现kΩ。Mod_ABS时宣称“高”SFP +模块是身体缺席主机槽。
模块插入检测管脚Mod_Abs,其在XFP光模块硬件接口中对应的管脚编号为12,在SFP+设备硬件接口中对应的管脚编号为6。 优选的是,其中,还包括:所述转换是指MCU对XFP光模块与SFP+设备硬件接口中定义相似的管脚,通过MCU上的指定引脚实现二者硬件接口的间接对接,进而实现相应管脚之间数据通信链路的畅通; 其中,所述XFP光模块...
Mod_ABS is connected to VeeT or VeeR in the SFP+ module. The host may pull this contact up to Vcc_Host with a resistor in the range 4.7 kΩ to10 kΩ.Mod_ABS is asserted “High” when the SFP+ module is physically absent from a host slot. RS0 and RS1 are module inputs and ...
