Viewing and Editing Card Information

Perform the steps given below to view and edit the Optical Fiber Amplifier (OFA) card details.

  1. On Optical Fiber Amplifier Card preview pane, click on Card Info link. The Card Info of the OFA card is displayed.

    Card Info- OFA Card

  2. To enable or disable OSC filter association on OFA card, select OSC Filter Association as 'Yes' or 'No' respectively.

    The OSC filter is a passive module plugged into an OFA card and has single or dual add and drop ports. It supports add and drop of supervisory channel wavelength, primarily at intermediate line amplifier (ILA) sites.

  3. To enable or disable OPM association on OFA card, select OPM Association as 'Yes' or 'No' respectively.

    The Optical Power Monitoring card is connected through the monitoring port on OFA card for optical power read out of up to 80 Channels at 50GHz intervals.

  4. Click Submit. A confirmation message is displayed.
  5. Click Accept Valid Modifications. A "Successfully Modified" message is displayed under the Warnings field.

    A click on Back link will direct you to the Card Info of the OFA card.

Viewing and Editing Amplifier Port Details

The number of amplifier ports on an OFA card depends on its version. For example, OFA-C-S17-FG (single version) has one Amplifier port while OFA-C-D17-FG (dual version) has two Amplifier ports on the front panel of the card.

Perform the steps given below to view and edit the amplifier port details on an OFA card.

  1. On Optical Fiber Amplifier Card preview pane, click on Amplifier Ports link. The Amplifier Ports preview pane is displayed.

Input Monitoring Mode

This parameter is applicable for HG and LG variant of OFA.

  • Low Power: Select when the input power is less. This is default selection with pre-configured value of 0 to -35 dBm.
  • High Power: Select when the input power is high, in case of booster amplifier. The pre-configured value is 10 to -25 dBm.

Low Power

  • Low Power
  • High Power

Automatic power shutdown

Select the desired option from the drop down menu.

  • Enable: Amplifier is turned off automatically in absence of input power.
  • Disable: Amplifier is not turned off in absence of input power.

Enable

  • Enable
  • Disable

Port Associated Degree

Allows you to enter an identifier for the amplifier port.

1 to 8

Operational Mode

Allows you to select the operational mode of the amplifier.

  • Automatic Gain Control (AGC): Automatically adjusts the gain of the amplifier irrespective of input power.
  • Automatic Power Control (APC): Automatically adjusts the power (or attenuation) of the amplifier to maintain constant average output level for wavelength stream in an fiber optic fiber.

It is recommended to select the 'Operational Mode' as 'Automatic Gain Control'.

Automatic Gain Control

  • Automatic Gain Control
  • Automatic Power Control

Set Amplifier Power (-5 to 20 dBm)

This parameter is editable only when the Operational Mode is selected as APC. Enter the input power threshold for the amplifier.

0

-5 to 20 dBm

Set Amplifier Tilt (dB)

This parameter is applicable only for variable gain amplifiers.

It is calculated by LMS (tilt of the least mean squares fitted line) of the gain spectrum; considering all channels' gain. Negative tilt means that longer wavelengths have Lower gain whereas a positive tilt means longer wavelengths have higher gain values.

0

+2 to -2

Mid Stage Access Loss(dB)

This parameter is applicable only for mid stage access type of amplifiers.

Displays the loss or attenuation introduced in the signal after dispersion compensation. The value should be less than 8 dBm.
