The DAS1 board integrates the functions of an optical amplifier unit, an FIU board (used to multiplexes the main optical channel and supervisory channel or demultiplexes the supervisory channel from the main channel signal), and an optical supervisory board. It supports gain adjustment, in-service monitoring of optical performance, gain locking, and transient state control.
For detailed functions and features, refer to Table 1.
| Function and Feature | Description |
|---|---|
| Basic function |
|
| Gain adjustment | The DAS1 board continuously adjusts the gain from 20 dB to 31 dB based on the input optical power. |
| Online optical performance monitoring | Provides the online monitoring interface. A small number of EDFA-amplified optical signals is output through this interface to the optical spectrum analysis board. In this manner, the spectrum and optical performance of the multiplexed signal are monitored without interrupting the services. |
| 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. |
| Alarms and performance events monitoring |
|
| OSC signal regeneration | The DAS1 board transmits signals from section to section. It also has the 3R function. In each regenerating station that has optical amplifiers, information can be correctly received and new supervisory signals are added. |
| Operating wavelength for OSC signals | 1511nm |
| Optical-layer ASON | Supported |
| eSFP | The RX/TX optical port supports pluggable optical modules. |
Specifications include optical specifications, dimensions, weight, and power consumption.

with the gain. The previous table lists the noise figure when the
noise figure uses the typical value. NOTE: The board supports a ±2.5 dB extended gain. The extended gain is only for the temporary use because it affects the gain flatness. | ||||||
