SFP Status Information (Port ▶SFP ▶Status ▶[connector])
SFP or Fiber Information
| Parameter | Description |
|---|---|
| Connector Type | The external cable connector provided as the media interface. |
| Vendor | The manufacturer name. This is a 16-character field that contains ASCII characters, padded on the right with ASCII spaces (20h). |
| Wave Length | Indicates the nominal transmitter wavelength at room temperature, expressed in nanometers. |
| Part Number | The manufacturer part number or product name. This is a 16-byte field that contains ASCII characters, padded on the right with ASCII spaces (20h). |
| Serial Number | The manufacturer serial number for the transceiver. This is a 16-character field that contains ASCII characters, padded on the right with ASCII spaces (20h). |
| Revision | The manufacturer’s product revision This is a 16-character field that contains ASCII characters, padded on the right with ASCII spaces (20h). |
| SFP Present | Indicates the presence of a recognized SFP. |
| Diagnostics | Supported or unsupported . A value of supported indicates that diagnostic information is provided in the SFP memory section. |
| Calibration |
|
| Thresholds | Indicates whether alarm and warning thresholds are supported. |
| Speed | The speed supported by the SFP, such as 1 Gbps . Two values are displayed:
|
Monitoring Information
| Parameter | Description |
|---|---|
| Temperature | Transceiver temperature, measured internally. Temperature accuracy is manufacturer-specific, but must be higher than 3 degrees Celsius for the specified operating temperature and voltage. |
| Laser Bias Current | Coupled TX output power, measured internally. Accuracy is manufacturer-specific but must be better than 3 dB for the specified operating temperature and voltage. Data is assumed to be based on measurement of a laser monitor photodiode current. Data is not valid when the transmitter is disabled. |
| Transmit Power | Coupled TX output power, measured internally. Accuracy is manufacturer-specific but must be better than 3 dB for the specified operating temperature and voltage. Data is assumed to be based on measurement of a laser monitor photodiode current. Data is not valid when the transmitter is disabled. |
| Receive Power | Received optical power, measured internally. Accuracy depends on the exact optical wavelength. For the manufacturer’s specified wavelength, accuracy should be better than 3 dB for the specified temperature and voltage. This accuracy should be maintained for input power levels up to the lesser of maximum transmitted or maximum received optical power per the appropriate standard. It should be maintained down to the minimum transmitted power minus cable plant loss (insertion loss or passive loss) per the appropriate standard. Accuracy beyond this minimum required received input optical power range is manufacturer specific. |
| Supply Voltage | Transceiver supply voltage, measured internally. Note: Transmitter supply voltage and receiver supply voltage are isolated in some transceivers. In that case, only one supply is monitored. Refer to the device specifications for details. |
SFP Thresholds
| Parameter | Description |
|---|---|
| Temperature | High Alarm: High-temperature alarm for the transceiver Low Alarm: Low-temperature alarm for the transceiver High Warning: High-temperature warning for the transceiver Low Warning: Low-temperature warning for the transceiver |
| Vcc | High Alarm: High-supply voltage alarm for the transceiver Low Alarm: Low-supply voltage alarm for the transceiver High Warning: High-supply voltage warning for the transceiver Low Warning: Low-supply voltage warning for the transceiver |
| Laser Bias Current | High Alarm: High-laser bias current alarm for the TX, expressed in microamperes Low Alarm: Low-laser bias current alarm for the TX, expressed in microamperes High Warning: High-laser bias current warning for the TX, expressed in microamperes Low Warning: Low-laser bias current warning for the TX, expressed in microamperes |
| Tx Power | High Alarm: High-output power alarm for the TX (~ -40 dBm to +8.2 dBm) Low Alarm: Low-output power alarm for the TX (~ -40 dBm to +8.2 dBm) High Warning: High-output power warning for the TX (~ -40 dBm to +8.2 dBm) Low Warning: Low-output power warning for the TX (~ -40 dBm to +8.2 dBm) |
| Rx Power | High Alarm: High-input power alarm for the RX (~ -40 dBm to +8.2 dBm) Low Alarm: Low-input power alarm for the RX (~ -40 dBm to +8.2 dBm) High Warning: High-input power warning for the RX (~ -40 dBm to +8.2 dBm) Low Warning: Low-input power warning for the RX (~ -40 dBm to +8.2 dBm) |
