TN11RAU201 Overview:

a Backward raman and erbium doped Fiber hybrid optical amplifier Unit.

Integrates a backward Raman unit and an EDFA unit and amplifies the input optical signals in C band. The total wavelengths range from 1529 nm to 1561 nm.

Supports the system to transmit services over different fiber spans without electrical regeneration.

Generates multi-channel pump light of high power, providing energy for the amplification of signals in the fiber.

Users can separately configure the gain adjustment point for the Raman amplifier and EDFA using the NMS.

Provides an in-service monitoring port (MON).

The Raman amplifier optical module supports the gain locking, maximum gain, and power locking modes.

EDFA optical module supports the gain locking and power locking modes.

Detects the pump driving current, back facet current, pump cooling current, temperature of the pump laser and the ambient temperature of the board.

The EDFA optical module can detect and report optical power.

The Raman amplifier optical module of the RAU2 board supports return loss detection.

The OTDR function can be used on the U2000. Monitoring figures and data are displayed on the U2000.

The Fiber Doctor Management System Software Fee License needs to be purchased for this function.

Supports Optical-layer ASON.


TN11RAU201 is a Backward Raman and erbium doped Fiber hybrid optical amplifier board, PN 03030PBW, apply to Huawei OSN8800 OSN6800 and OSN3800. RAU has two versions TNTN11 and TN12, TN12RAU2 can replace TN11RAU2.

Additional information



Q: How many hardware version does RAU have?

A: RAU is available in TN11 and TN12,  The mappings between the board and equipment are as below:

Board General 8800 T64 Subrack Enhanced 8800 T64 Subrack General 8800 T32 Subrack Enhanced 8800 T32 Subrack 8800 T16 Subrack 8800 Universal Platform Subrack 6800 Subrack 3800 Chassis
When the RAU2 board is used in the OptiX OSN 3800 chassis, the TN23SCC board must be used.

Q: What are the difference between TN11RAU2 and TN12RAU2?



TN12RAU2 board supports the line fiber quality monitoring function, fiber connection detect (FCD), quick shutdown of the Raman laser, and safe turn-on of the Raman laser while the TN11RAU2 board does not.


The front panels of TN11RAU2 and TN12RAU2 boards are different. On the front panel of  TN12RAU2, there are the FCD button and indicator, interlock switch. There is no such button, indicator, or switch on the front panel of TN11RAU2.
