| 2. | Technical requirement for optical line terminals at 4 139264kbit s 4 139264kbit s光端机技术要求 |
| 3. | Technical condition for pdh optical line terminals used in access neteork 接人网用pdh光端机技术条件 |
| 4. | Olt : optical line terminal 光纤线路终端 |
| 5. | The merit of travelling waves location is its high precision , but it has dead line if the fault location is close to the line terminal or the fault occurs at the time close to zero point of current 行波法测距的优点是精度高,但对近区故障或电流过零附近时刻发生的故障存在测距死区。 |
| 6. | The epon network includes optical line terminal ( olt ) and optical network unit ( onu ) . onuses share the optical distribution network ( odn ) trunk fiber back to the central office Epon系统采用局端机( olt ) -用户端机( olt )两级结构,中间由无源光分配网络完成下行光功率分配和上行光耦合。 |
| 7. | Alcatel s 7340 product line include multiple network units such as packet optical line terminal , picture optical line terminal , home optical network terminal and network unit management system Alcatel的7340产品线包括多个网元,如分组光线路终端,图象光线路终端、家庭光网络终端以及网元管理系统。 |
| 8. | Because affected by the type of lines , fault resistance and two sides systems , fault analytical location has lower precision , but it has no dead line and is more better accurate if the fault location is close to the line terminal 故障分析法由于受线路类型、过渡电阻、两端系统的影响测距精度较差,但故障分析法不存在测距死区,尤其对近区故障的测距较为准确。 |
