Huawei OptiX OSN 9800 Reconfigurable Optical Add/Drop Multiplexer Boards TN12TD2001 03030PGE

Basic function

Broadcasts a multi-wavelength signal that contains up to 20 optical signals for local dropping (colorless application).

WDM specification

Supports the DWDM specification.

Compensation for broadcast loss

Uses the built-in EDFA module to compensate for broadcast loss.

• The EDFA module works in gain-locking mode.

Adding or dropping one or more channels does not affect the signal gain of other channels

The signal power jitter on some channels does not affect the signal gain of other channels.

• The EDFA module has the transient state control function. When channels are added or dropped, the OptiX OSN 9800 Universal Platform Subrack can be upgraded or expanded without interrupting services because this function can suppress channel optical power jitter.

NOTE:

The TN97TD20 board does not support the function.

In-service optical performance monitoring

Provides an in-service monitoring port. Through this optical port, a small number of optical signals can be output to an optical spectrum analyzer or an optical spectrum analyzer board. In this manner, the spectrum and optical performance of the multiplexed optical signals can be monitored without interrupting services.

NOTE:

The TN97TD20 board does not support the function.

Alarm and performance event monitoring

• Monitors and reports the optical power of the built-in EDFA module.
• Monitors the temperature of the pump laser.
• Detects the drive current, back facet current, pump cooling current, and temperature of the pump laser and the ambient temperature of the board.

NOTE:

The TN97TD20 board does not support the function.

Optical-layer ASON

Supported

Spectrum application

Only the TN97TD20 board supports extended C-band wavelengths
