h3c长距离光模块使用注意事项的通知

关于长距离光模块使用注意事项的通知在近期的一些项目中，连续发生长距离光模块（40KM及以上）故障的情况，由于长距离光模块对接收光功率要求高，使用不当容易导致损坏，为减少使用不当导致长距离光模块的故障，使用中有如下注意事项。【涉及产品】光模块-SFP-GE-单模模块-(1550nm,100km,LC)（BOM编码0231A321）光模块-SFP-GE-单模模块-(1550nm,70km,LC)（BOM编码02312173）光模块-SFP-GE-单模模块-(1550nm,40km,LC)（BOM编码02312172）光模块-SFP-GE-单模模块-(1310nm,40km,LC)（BOM编码02312170）光模块-SFP100M/155M单模长距模块-(1550nm,80km,LC)（BOM编码0231A090）光模块-SFP100M/155M单模模块-（1310nm,40km,LC)（BOM编码0231A089）光模块-SFP-GE-单模模块-CWDM-(1550nm,70km,LC)（BOM编码0231A449）光模块-SFP-GE-单模模块-CWDM-(1570nm,70km,LC)（BOM编码0231A450）光模块-SFP-GE-单模模块-CWDM-(1590nm,70km,LC)（BOM编码0231A451）光模块-SFP-GE-单模模块-CWDM-(1610nm,70km,LC)（BOM编码0231A452）光模块-SFP-GE-单模模块-CWDM-(1470nm,70km,LC)（BOM编码0231A453）光模块-SFP-GE-单模模块-CWDM-(1490nm,70km,LC)（BOM编码0231A454）光模块-SFP-GE-单模模块-CWDM-(1510nm,70km,LC)（BOM编码0231A455）光模块-SFP-GE-单模模块-CWDM-(1530nm,70km,LC)（BOM编码0231A456）光模块-XFP-10G-单模模块-(1550nm,80km,LC)（BOM编码0231A41G）；XFP万兆光模块(1550nm,40km,LC)（BOM编码0231A72X）；XFP光模块-(1560.61nm,80km,LC)（BOM编码0231A0JD）XFP光模块-(1559.79nm,80km,LC)（BOM编码0231A0JE）XFP光模块-(1558.98nm,80km,LC)（BOM编码0231A0JJ）XFP光模块-(1542.94nm,80km,LC)（BOM编码0231A0JM）XFP光模块-(1542.14nm,80km,LC)（BOM编码0231A0JK）XFP光模块-(1540.56nm,80km,LC)（BOM编码0231A0JL）XFP光模块-(1539.77nm,80km,LC)（BOM编码0231A0JG）XFP光模块-(1538.98nm,80km,LC)（BOM编码0231A0JF）光模块-XENPAK-10G-单模模块-(1550nm,40km,SC)（BOM编码0231A324）光模块-XENPAK-10G-单模模块-(1550nm,80km,SC)（BOM编码0231A08H）光模块-SFP-2.5G-单模模块-(1310nm,40km,LC)（BOM编码0231A04A）光模块-SFP-2.5G-单模模块-(1550nm,80km,LC)（BOM编码0231A04B）622MSFP光模块-(1550nm,80km,LC)（BOM编码0231A04C）622MSFP光模块-(1310nm,40km,LC)（BOM编码0231A04D）【使用注意事项说明】长距离光模块对接收光功率范围要求严格，如果超出接收灵敏度，就会导致光模块故障，使用方法及注意事项如下：1、安装上述长距离光模块到设备后不要立刻连接光纤，先用命令行displaytransceiverdiagnosisinterface读取光模块收发光功率，查看发光功率是否在正常范围内，收光功率不是+1dB等异常值，没连接光纤情况下软件通常显示接收光功率可能为-40dB或比较低的值。命令举例如下：SysnamedisplaytransceiverdiagnosisinterfaceGigabitethernet3/0/1GigabitEthernet3/0/1transceiverdiagnosticinformation:Currentdiagnosticparameters:Temp(°C)Voltage(V)Bias(mA)RXpower(dBM)TXpower(dBM)363.316.13-40.00-1.002、有条件情况下建议使用光功率计测试收发光功率在正常接收范围内才能连接光纤至上述长距光模块。3、任何情况下不能使用光纤直接打环对上述长距光模块进行测试，如果需要必须连接光衰减器使接收光功率在接收范围内方可进行环回测试。4、使用长距光模块，接收功率必须有一定余量，实际接收功率相比接收灵敏度预留3dB以上，如果不满足需要增加衰减器。附录：1、万兆长距XFP光模块参数表对外型号编码波长输出功率输入功率接口类型距离对外描述XFPXFP-LH40-SM1550-F10231A72X1550-1.0to2.0-11.3to-1.0LC40kmXFP万兆光模块(1550nm,40km,LC)XFP-LH80-SM15500231A41G15500to4.0-24.0to-7.0LC80kmXFP-10GXFP光模块(1550nm,80km,LC)XFP-LX-SM1560.610231A0JD1560.61-1to3.0-24.0to-7.0LC80kmXFP光模块-(1560.61nm,80km,LC)XFP-LX-SM1559.790231A0JE1559.79LC80kmXFP光模块-(1559.79nm,80km,LC)XFP-LX-SM1558.980231A0JJ1558.98LC80kmXFP光模块-(1558.98nm,80km,LC)XFP-LX-SM1542.940231A0JM1542.94LC80kmXFP光模块-(1542.94nm,80km,LC)XFP-LX-SM1542.140231A0JK1542.14LC80kmXFP光模块-(1542.14nm,80km,LC)XFP-LX-SM1540.560231A0JL1540.56LC80kmXFP光模块-(1540.56nm,80km,LC)XFP-LX-SM1539.770231A0JG1539.77LC80kmXFP光模块-(1539.77nm,80km,LC)XFP-LX-SM1538.980231A0JF1538.98LC80kmXFP光模块-(1538.98nm,80km,LC)2、千兆长距光模块参数表对外型号编码波长输出功率输入功率接口类型距离对外描述SFPSFP-GE-LH40-SM1310023121701310-2.0to5.0-22.0to-3.0LC40kmSFP千兆模块-(1310nm,40km,LC)SFP-GE-LH40-SM1550023121721550-4.0to1.0-21.0to-3.0LC40kmSFP千兆模块-(1550nm,40km,LC)SFP-GE-LH70-SM1550023121731550-4.0to-22.0toLC70kmSFP千兆模块5.0-3.0-(1550nm,70km,LC)SFP-GE-LH100-SM15500231A32115500to5.0-30.0to-9.0LC100kmSFP千兆模块-(1550nm,100km,LC)SFP-GE-LH70-SM1470-CW0231A45314700to5.0-23.0to-3.0LC70kmSFP千兆模块-(1470nm,70km,LC)SFP-GE-LH70-SM1490-CW0231A45414900to5.0-23.0to-3.0LC70kmSFP千兆模块-(1490nm,70km,LC)SFP-GE-LH70-SM1510-CW0231A45515100to5.0-23.0to-3.0LC70kmSFP千兆模块-(1510nm,70km,LC)SFP-GE-LH70-SM1530-CW0231A45615300to5.0-23.0to-3.0LC70kmSFP千兆模块-(1530nm,70km,LC)SFP-GE-LH70-SM1550-CW0231A44915500to5.0-23.0to-3.0LC70kmSFP千兆模块-(1550nm,70km,LC)SFP-GE-LH70-SM1570-CW0231A45015700to5.0-23.0to-3.0LC70kmSFP千兆模块-(1570nm,70km,LC)SFP-GE-LH70-SM1590-CW0231A45115900to5.0-23.0to-3.0LC70kmSFP千兆模块-(1590nm,70km,LC)SFP-GE-LH70-SM1610-CW0231A45216100to5.0-23.0to-3.0LC70kmSFP千兆模块-(1610nm,70km,LC)3、100M/155M长距光模块参数表对外型号编码波长输出功率输入功率接口类型距离对外描述100M/155MSFP-FE-LH40-SM13100231A0891310-5.0to0-34.0to-9.0LC40km光模块-SFP100M/155M单模模块-（1310nm,40km,LC)SFP-FE-LH80-SM15500231A0901550-5.0to0-34.0to-10.0LC80km光模块-SFP100M/155M单模长距模块-(1550nm,80km,LC)4、622M长距光模块参数表对外型号编码波长输出功率输入功率接口类型距离对外描述622MSFP-622M-LH80-SM15500231A40C1550nm-3.0to2-28.0to-7.0LC80km622MSFP光模块-(1550nm,80km,LC)SFP-622M-LH40-SM13100231A40D1310nm-3.0to2-28.0to-7.0LC40km622MSFP光模块-(1310nm,40km,LC)5、2.5G长距光模块参数表对外型号编码波长输出功率输入功率接口类型距离对外描述2.5GSFP-2.5G-LH40-SM13100231A04A1310nm-2.0to3-27.0to-9.0LC40km光模块-SFP2.5GPOS单模中距模块-(1310nm,40km,LC)SFP-2.5G-LH80-SM15500231A04B1550nm-2.0to3-28.0to-8.0LC80km光模块-SFP2.5GPOS单模长距模块-(1550nm,80km,LC)6、10GXENPAK光模块参数表对外型号编码波长输出功率输入功率接口类型距离对外描述10GXENPAKXENPAK-LH40-SM15500231A3241550nm-4.7to4-11.3to-1.0SC40km光模块-XENPAK-10G-单模模块-(1550nm,40km,SC)XENPAK-LH80-SM15500231A08H1550nm0to4.0-22.0to-7.0SC80km光模块-SFP2.5GPOS单模长距模块-(1550nm,80km,LC)
