Access-layer devices are required to provide access for a large number of information terminals on both telecom networks and campus networks. Access-layer devices use various technologies. Huawei’s broadband "access network" devices refer to the copper line access devices that mainly use the xDSL technology and the optical access devices that mainly use the PON technology.
If you want to test the optical transmit power of the ONU, connect a common power meter to the upstream port of the ONU and select the 1310 nm wavelength to read the power value.
Compared with GPON, XGS-PON can cover more users and provide higher bandwidth without changing the ODN network architecture.
In an ODN network, which of the following protection modes can protect only backbone optical fibers?
After the server receives the DHCP REQUEST packet, if the server cannot allocate an IP address due to certain reasons, the server sends the ( ) packet as a response.
In the Simple Network Management Protocol (SNMP) structure, the Agent is an agent process running on a managed device. After a managed device receives a request from the NMS, the Agent responds to the request. The Agent collects device status information, operates managed devices by executing commands on the NMS, and reports alarms to the NMS.
Which of the following optical modules has the most sufficient optical loss budget?
Which of the following optical modules has the most sufficient optical loss budget?
Generally, which of the following is not a split ratio of an optical splitter in a PON?
In the downstream direction of the GPON, all ONUs receive the same data because the broadcast mode is adopted. In the upstream direction, because the same optical splitter is used, the data of a branch fiber can also be received by another branch fiber.
