Use this procedure to configure optical safety. This task helps you complete the required configuration, verification, or management action in Cisco Optical Site Manager.

Configure optical safety parameters to ensure compliance with laser safety standards. The system can automatically shut down or control laser output power during fault conditions such as fiber breaks or signal loss.

Optical safety provisioning protects optical components and personnel from hazardous laser exposure. This process includes configuring parameters for automatic laser shutdown (ALS) modes, optical safety remote interlock (OSRI), and recovery pulse settings on various optical cards, such as line cards, amplifier cards, and service channel cards.

Before you begin

Follow these steps to configure the optical safety parameters for cards.

Procedure

  1. Click the Maintenance tab.

  2. Click the Optical Safety section to expand it.

  3. Modify required settings as described in the Table 1 table.

  4. Click Apply to save the changes.

The system monitors optical signals. When needed, it automatically activates safety mechanisms, such as ALS, to shut down laser output.

Parameter

Description

Options

Interface

(Display only) Displays the port name, port type, and direction.

—

Supported Safety

(Display only) Displays the supported safety mechanism.

  • ALS for line cards and control cards.

  • ALS-OSRI for amplifier cards.

ALS Mode

Automatic laser shutdown mode. ALS mode is disabled for RX ALS interfaces.

From the drop-down list, choose one of the following:

  • ALS-Disabled—Deactivates ALS.

  • Automatic Restart—(Default) ALS is active. The power is automatically shut down when needed, and it automatically tries to restart using a probe pulse until the cause of the failure is repaired.

  • Manual Restart

OSRI

Optical safety remote interlock. The default value is OSRI-OFF. When set to OSRI-ON, the TX output power is shut down.

Note

OSRI configuration is not supported on the transponder and muxponder cards.

From the drop-down list, choose one of the following:

  • OSRI-OFF

  • OSRI-ON

ALS Status

(Display only) ALS status of the device.

  • Working

  • Shutdown

Recovery Pulse Interval (Sec.)

Displays the interval between two optical power pulses.

60 to 300 seconds.

Recovery Pulse Duration (Sec.)

Displays the duration of the optical power pulse that begins when an amplifier restarts.

2 to 100 seconds

Manual Restart

Triggers manual restart for the ALS interface. Manual restart does not occur if Mode is set to Automatic Restart or Disabled.
