| # TRANSCEIVER-1: Telemetry: 400ZR_PLUS Chromatic Dispersion(CD) telemetry values streaming | ||
|
|
||
| ## Summary | ||
|
|
||
| Validate 400ZR_PLUS optics module reports accurate CD telemetry values. | ||
|
|
||
| Chromatic Dispersion is frequency dependent change in signal phase velocity due | ||
| to fiber measured in ps/nm | ||
|
|
||
| The test must be repeated for each supported operational-mode or as agreed between the vendor and customer. | ||
|
|
||
| ## Procedure | ||
|
|
||
| * Connect two ZR_PLUS interfaces using a duplex LC fiber jumper such that TX | ||
| output power of one is the RX input power of the other module. Connection | ||
| between the modules should pass through an optical switch that can be | ||
| controlled through automation to simulate a fiber cut. | ||
| * To establish a point to point ZR_PLUS link ensure the following: | ||
| * Both transceivers states are enabled | ||
| * Both transceivers are set to a valid target TX output power | ||
| example -3 dBm | ||
| * Both transceivers are tuned to a valid centre frequency | ||
| example 193.1 THz | ||
| * With the ZR_PLUS link is established as explained above, verify that the | ||
| following ZR_PLUS transceiver telemetry paths exist and are streamed for both | ||
| the ZR_PLUS optics | ||
| * /platform/components/component/optical-channel/state/chromatic-dispersion/instant | ||
| * /platform/components/component/optical-channel/state/chromatic-dispersion/avg | ||
| * /platform/components/component/optical-channel/state/chromatic-dispersion/min | ||
| * /platform/components/component/optical-channel/state/chromatic-dispersion/max | ||
|
|
||
| * When the modules or the devices are still in a boot stage, they must not | ||
| stream any invalid string values like "nil" or "-inf" until valid values | ||
| are available for streaming. | ||
|
|
||
| * CD streamed values must always be of type Decimal64. | ||
| When link interfaces are in down state 0 must be reported as a valid | ||
| value. | ||
|
|
||
| **Note:** For min, max, and avg values, 10 second sampling is preferred. If | ||
| 10 seconds is not supported, the sampling interval used must be | ||
| communicated. | ||
|
|
||
|
|
||
| * Verify that the optics CD is updated after the interface flaps. | ||
|
|
||
| * Enable a pair of ZR_PLUS interfaces on the DUT as explained above. | ||
| * Verify the ZR_PLUS optics CD telemetry values are in the normal range. | ||
| * Disable or shut down the interface on the DUT. | ||
| * Verify with interfaces in down state both optics are streaming Decimal64 0 | ||
| value for CD. | ||
| * Re-enable the interfaces on the DUT. | ||
| * Verify the ZR_PLUS optics CD telemetry values are updated to the | ||
| value in the normal range again. | ||
| * Typical CD expected value range is 0 to 2400 ps/nm. | ||
|
|
||
| * Verify that the optics CD is updated after a fiber cut. | ||
|
|
||
| * Enable a pair of ZR_PLUS interfaces on the DUT as explained above. | ||
| * Verify the ZR_PLUS optics CD telemetry values are in the normal | ||
| range. | ||
| * Simulate a fiber cut using the optical switch that sits in-between the | ||
| DUT ports. | ||
| * Verify with link in down state due to fiber cut both optics are streaming | ||
| Decimal64 0 value for CD. | ||
| * Re-enable the optical switch connection to clear the fiber cut fault. | ||
| * Verify the ZR_PLUS optics CD telemetry values are updated to the value in the normal | ||
| range again. | ||
| * Typical CD expected value range is 0 to 2400 ps/nm. | ||

| # TRANSCEIVER-10: Telemetry: 400ZR_PLUS Optics FEC(Forward Error Correction) Uncorrectable Frames Streaming. | ||
|
|
||
| ## Summary | ||
|
|
||
| Validate 400ZR_PLUS optics module reports uncorrectable FEC frames count. | ||
|
|
||
| This observable represents the number of uncorrectable FEC frames, | ||
| measured as RS(544,514) equivalent frames, in a short interval. | ||
| This is a post-FEC decoder error metric. | ||
|
|
||
| ## Procedure | ||
|
|
||
| * Connect two ZR_PLUS interfaces using a duplex LC fiber jumper such that TX | ||
| output power of one is the RX input power of the other module. | ||
| * To establish a point to point ZR_PLUS link ensure the following: | ||
| * Both transceivers state is enabled | ||
| * Both transceivers are set to a valid target TX output power | ||
| example -3 dBm | ||
| * Both transceivers are tuned to a valid centre frequency | ||
| example 193.1 THz | ||
| * With the ZR_PLUS link established as explained above, verify that the | ||
| following ZR_PLUS transceiver telemetry path exist and is streamed for both | ||
| the ZR_PLUS optics. | ||
| * /terminal-device/logical-channels/channel/otn/state/fec-uncorrectable-blocks | ||
| * Verify that the reported data should be of type yang:counter64. | ||
| * When the modules or the devices are still in a boot stage, they must not | ||
| stream any invalid string values like "nil" or "-inf". | ||
| * Toggle the interface state using /interfaces/interface/config/enabled and | ||
| verify relevant FEC uncorrectable frame count is streamed. If there are no | ||
| errors a value of 0 should be streamed for no FEC uncorrectable frames. | ||

| # TRANSCEIVER-3: Telemetry: 400ZR_PLUS Optics firmware version streaming | ||
|
|
||
| ## Summary | ||
|

||
| Validate 400ZR_PLUS optics module reports correct firmware version. | ||
|
|
||
| ## Procedure | ||
|
|
||
| * Plug in the ZR_PLUS module in the host port and make sure the transceiver | ||
| state is enabled and host is able to detect the module. | ||
| * With the module correctly recognized verify it reports correct firmware | ||
| version through the following telemetry path | ||
| * /platform/components/component/state/firmware-version | ||
|
|
||
| * Verify that the modules firmware version is reported correctly after a | ||
| optic software reset. | ||
|
|
||
| * With ZR_PLUS module plugged in the host and properly recognized | ||
| * Verify the ZR_PLUS optics firmware version is correctly reported via the | ||
| streaming telemetry path above. | ||
| * Reset the optic through software | ||
| * Verify the ZR_PLUS optics still reports correct firmware version. | ||
