Super C-band 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.

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.

Has a built-in VOA module to adjust optical power.

Supports Optical-layer ASON.

As a type of optical amplifier unit, the SRAU board integrates a backward Raman unit, an EDFA module and a VOA. Different from an EDFA, the SRAU board is used to improve system performance. It amplifies optical signals at the receive end.

Tech Specs
Function and Feature Description
Gain adjustment Users can separately configure the gain adjustment point for the Raman amplifier and EDFA using the NMS. The SRAU continuously adjusts the gain continuously based on the input optical power:
G.652 fibers: 22 dB to 30 dB
LEAF fibers: 22 dB to 28 dB
G.653 fibers: 22 dB to 28 dB
G.654B fibers: 18 dB to 24 dB
G.656 fibers/TWRS fibers/TWC fibers/TW+ fibers/Teralight fibers/LS fibers/G.654A fibers: 22 dB to 30 dB
G.652 fibers: 27 dB to 38 dB
LEAF fibers: 27 dB to 36 dB
G.653 fibers: 27 dB to 36 dB
G.654B fibers: 23 dB to 32 dB
G.656 fibers/TWRS fibers/TWC fibers/TW+ fibers/Teralight fibers/LS fibers/G.654A fibers: 27 dB to 38 dB
Online optical performance monitoring Provides an in-service monitoring port. This port connects to an optical spectrum analyzer or spectrum analyzer unit to monitor the signal power performance without affecting traffic.
Working mode The Raman amplifier module supports the gain locking, maximum gain, and power locking modes.
The EDFA module 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.
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 supports return loss detection.
Line fiber quality monitoring function The line fiber quality monitoring function can be used on the NMS. Monitoring figures and data are displayed on the NMS.
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.

Q: How many hardware version does SRAU have?

A: SRAU is available in TN11. The mappings between the board and equipment are as below:

Q: Can I return/exchange board if not compatible with my system?

A: Yes, please tell our sales team your system and main control board version, before purchase.

Q: The board is new or refurbished?

A: It is original new, not been used.

Q: What is the lead time for TN11SRAU02 board?

A: In normal condition is 5 days, better to confirm with our sales team before your purchase.
