Description

TN11RAU1 Overview

TN11RAU1 backward raman and erbium doped fiber hybrid optical amplifier unit applied to OptiX OSN 8800.

The OptiX OSN 8800 Intelligent Optical Transport Platform (OptiX OSN 8800 for short) is a new generation of intelligent MS-OTN product. The OptiX OSN 8800 can interconnect with any product from the OptiX OSN product series, such as the OptiX OSN 1800, to form an end-to-end OTN network. The OptiX OSN 8800 T32/T16 supports unified switching and control based on ODUk, VC, and packets, achieving unified switching and transmission for multiple services on a single multi-service optical transport network (MS-OTN). The OptiX OSN 6800 Intelligent Optical Transport Platform (OptiX OSN 6800 for short) is referred to as Huawei next generation intelligent optical transport platform. The OptiX OSN 6800 is for area backbones, local networks, metropolitan convergence layers and metropolitan core layers. It may also work with other WDM, SDH/SONET equipment to offer a complete Metro WDM solution.

Item TN11RAU1
Basic function
  • 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.
  • The TN12RAU1 board supports the interlock switch. The interlock switch of a LINE port on the panel controls the power-on and power-off of the board and prevents eyes from being injured by laser when an optical fiber is inserted into or removed from the LINE port.
  • The TN12RAU1 board has a built-in VOA module to adjust optical power.
Gain adjustment
The RAU1 continuously adjusts the gain continuously based on the input optical power:
  • G.652 fibers: 19dB to 33dB
  • LEAF fibers: 19dB to 35dB
  • G.653 fibers: 19dB to 35dB
  • TWRS fibers: 19dB to 35dB
  • TW-C fibers: 19dB to 35dB
  • TWPLUS fibers: 19dB to 35dB
  • SMFLS fibers: 19dB to 35dB
  • G.656 fibers: 19dB to 35dB
  • G.654A fibers: 19dB to 33dB
  • TERA_LIGHT fibers: 19dB to 35dB
  • G.654B fibers: 19dB to 29dB
NOTE:
Users can separately configure the gain adjustment point for the Raman amplifier and EDFA using the NMS.
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.
Working mode
The Raman amplifier module supports the gain locking, maximum gain, and power locking modes.
  • In gain locking mode. This mode applies to multi-span or single-short-span systems that use G.652/G.653/LEAF/TWRS/TW-C/TWPLUS/SMFLS/G.656/G.654A/TERA_LIGHT/G.654B fibers. In addition, the gain of the Raman unit is tunable and users can query the actual gain of the Raman unit.
  • The maximum gain mode applies to single-UL-span systems that use G.652/G.653/LEAF/TWRS/TW-C/TWPLUS/SMFLS/G.656/G.654A/TERA_LIGHT/G.654B fibers. In this mode, the Raman amplifier module automatically adjusts its pump power to ensure that its gain reaches the maximum value. In addition, users can query the actual gain of the Raman amplifier module.
  • In the pump power mode, users can set the pump power for the Raman amplifier module. This mode applies to systems that use any fibers but the G.652/G.653/LEAF/TWRS/TW-C/TWPLUS/SMFLS/G.656/G.654A/TERA_LIGHT/G.654B fibers or to situations in which the pump power of the Raman amplifier module must be adjusted manually.
The EDFA module supports the gain locking and power locking modes.
  • In the gain locking mode, the gain of the EDFA module is tunable and users can query the actual gain of the EDFA module. The gain locking mode is enabled by default.
  • The power locking mode is used for the commissioning and fault location purposes.
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.
Alarms and performance events monitoring
  • 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 module of the RAU1 board supports return loss detection.
Line fiber quality monitoring function The line fiber quality monitoring 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.
FCD function The FCD button and indicator are provided. You can press the FCD button on the front panel to trigger FCD. The detection process and results can be identified by the FCD indicator blinking frequency and indicator status. For details, see Front Panel.
Safe turn-on of the Raman laser When the Raman laser is turned on, the OTDR meter function is automatically enabled to detect fiber connections and therefore ensure that the laser is properly started, avoiding fiber burning due to inappropriate fiber connections. If the Raman laser fails to be turned on, the line fiber quality monitoring function can be used to further identify fault points.
Quick shutdown of the Raman laser The quick shutdown of the Raman laser is supported. When fiber removal, fiber cut, or serious fiber bend occurs within 500 m around the site where the board housing the Raman laser is located, this function ensures that the pump light of the Raman laser is shut down within 100 ms. When a fiber removal or fiber cut occurs beyond 500 m around the site, the implementation of this function is related to the actual fiber line quality.
Optical-layer ASON Supported
