TN12OBU205 Is Huawei OSN 8800 Optical Amplifier Board
Huawei OSN 8800 Optical Amplifier Board TN12OBU205 Overview
OBU2: optical booster unit
The available functional versions of the OBU2 board are TN11, TN12, TN13 and TN14.
As a type of optical amplifier unit, the OBU1 amplifies optical signals.
The OBU2 is mainly used for online optical performance monitoring, gain lock, and transient control.
The OBU2 board consists of the EDFA optical module, driving and detection module, control and communication module, and power supply module.
The characteristic code for the OBU2 board contains six characters and digits, indicating the gain range and the maximum nominal input optical power of the signals processed by the board.
Functions and features of the TN12OBU205 board
Function and Feature |
Description |
Basic function |
|
Typical gain |
The typical gain of the TN11OBU2/TN12OBU2/TN13OBU2 is 23 dB. The typical gain of the TN14OBU2 is 20 dB. NOTE: OBU2 Specifications only provides the value of nominal gain. Actual gain includes the noise, and the value is bigger than that of nominal gain. |
Online optical performance monitoring |
Provides an in-service monitoring port (MON). This port connects to an optical spectrum analyzer or spectrum analyzer unit to monitor the spectrum and optical performance of the multiplexed signal without affecting traffic. |
Gain lock function |
The EDFA inside the board has the gain lock function. Adding or dropping one or more channels or optical signal fluctuation does not affect the signal gain of other channels. |
Working mode |
Supports the gain locking and power locking modes.
|
Transient control function |
The EDFA inside the board has the transient control function. When channels are added or dropped, the board can suppress the fluctuation of the optical power in the path so as to implement the smooth upgrading and expansion. |
