When managing a VSOL OLT (Optical Line Terminal), checking the optical transceiver details is crucial for monitoring the health and performance of your fiber-optic network. The CLI mode (Command Line Interface) provides direct access to the OLT's functionalities and diagnostic tools, allowing network administrators to retrieve and interpret detailed transceiver information. Here's a breakdown of the process:
What are Optical Transceiver Details?
Optical transceivers in an OLT are hardware modules that convert electrical signals to optical signals and vice versa, facilitating data transmission over fiber optics. Key details of these transceivers include:
* Wavelength: The operating wavelength of the transceiver (e.g.,1330 nm, 1270 nm 1310 nm, 1550 nm).
* Tx Power: The optical signal strength sent by the transceiver.
* Rx Power: The optical signal strength received by the transceiver.
* Temperature: The current temperature of the transceiver, which can indicate performance issues.
* Voltage: The operating voltage of the transceiver.
Monitoring these metrics helps ensure optimal network performance and prevents hardware failures.
Accessing the CLI on Vsol OLT:
1. Establish a connection:
* Use SSH, Telnet, or a serial connection (via a console cable) to connect to the OLT.
* Open a terminal emolator Like PuTTY or Tera Term.
2. Login to the OLT:
* Enter the OLT's IP address (if using SSH or telnet) and provide login credentials.
* You will see a command prompt after successful login.
Gigaports SFP Optical Transceiver Details Commands:
Once logged into the CLI, use specific commands to display Gigaports SFP transceiver information. If you want to see the details of the transceiver of the sfp Gigaport, you have to enter the port and then give the command. The commands are given below:
Username:admin
Password: Xpon@Olt9417#
epon-OLT> ena
Password: Xpon@Olt9417#
epon-OLT#configure terminal
epon-OLT(config)# interface gigabitethernet 0/1
epon-OLT(config-if-ge0/1)# show optical transceiver
Temperature: 40.949 C
Voltage: 3.342 V
TxBias: 21.468 mA
TxPower: -6.029 dBm
RxPower: -11.302 dBm
If you do not understand the above commands, then see the image below, I hope you will understand very easily.
PON ports SFP Optical Transceiver Details Commands:
Use specific commands to display Gigaports SFP transceiver information. If you want to see the details of the transceiver of the sfp Gigaport, you have to enter the port and then give the command. The commands are given below:
Username:admin
Password: Xpon@Olt9417#
epon-OLT> ena
Password: Xpon@Olt9417#
epon-OLT#configure terminal
epon-OLT(config)# interface epon 0/1
epon-OLT(config-pon-0/1)# show pon optical transceiver
Tempperature : 44.54 .C
Voltage : 3.27 V
Bias Current : 21.50 mA
Transmit Power : 5638 uW (7.51 dBm)
epon-OLT(config-pon-0/1)#
If you do not understand the above commands, then see the image below, I hope you will understand very easily.
All ONU/ONT Optical Diagnosis Details Commands:
Use specific commands to display onu/ont Optical diagnosis information. If you want to see details of the ONU/ONT Optical diagnosis then follow the commands. The commands are given below:
Username:admin
Password: Xpon@Olt9417#
epon-OLT> ena
Password: Xpon@Olt9417#
epon-OLT#configure terminal
epon-OLT(config)# show onu opm-diag all
epon-OLT(config)#
If you want to see the optical diagnosis details of the ONU of a specific PON port, you can only mention the PON port. If you do not understand the above commands, then see the image below. I hope you will understand very easily.
Interpreting the Output
The CLI will provide data in tabular or structured format, typically including:
Port ID: Identifies the specific EPON/GPON interface.
Tx Power (dBm): Must be within the acceptable range for the specific transceiver type. Low TX power indicates potential transmission issues.
Rx Power (dBm): Must be strong enough to ensure proper signal reception.
Temperature (°C): Abnormal temperatures can signal hardware stress or failure.
Voltage (V): Deviations from the normal operating range can lead to transceiver instability.
By using the CLI effectively, you can maintain the reliability and performance of your Vsol OLT and its connected network
