17 +**Interrogator Unit**
17 17  
18 -The iDAS system consists of the following components:
19 +* The heart of the iDAS system, this unit contains the laser source, a detector for capturing backscattered light, and electronics to process this signal. It's critical for generating and interpreting the data collected by the optical fiber.
19 19  
20 -1. **Interrogator unit:** This unit houses the laser, detector, and electronics for processing the backscattered light signal. It records various settings such as the optical system configurations, spatial sampling rates, and the duration of data acquisition. More than one interrogator may be used in an experiment. Each unit should have a unique identifier and is described in its respective metadata block.
21 -1. **Optical fiber:** The optical fiber is the sensor that is used to measure strain rate.
22 -1. **Data acquisition software**: This software is used to control the interrogator unit and to acquire and process the data. It records various settings such as the optical system configurations, spatial sampling rates, and the duration of data acquisition.
21 +**Optical Fiber**
23 23  
24 -----
23 +* This component acts as a long, distributed sensor. Strain rates along this fiber are what the iDAS system measures and analyzes.
25 25  
25 +**Data Acquisition Software**
26 +
27 +* This software interfaces with the interrogator unit, allowing users to configure acquisition parameters, initiate data capture, and process the collected data.

37 +* **Function:** The interrogator unit is the core component of a DAS system. It sends laser pulses through the optical fiber and measures the backscattered light.
38 +* **Recording Information:** It records various settings such as the optical system configurations, spatial sampling rates, and the duration of data acquisition.
39 +* **Multiple Interrogators:** More than one interrogator may be used in an experiment. Each unit should have a unique identifier and is described in its respective metadata block.
40 +
41 +==== **2. Surface Installation** ====
42 +
30 30  * **Cable Arrangement:** The optical fiber cable can be a single long continuous cable or multiple cables with connectors, used across different installation environments.
31 31  * **Cable Types:** Cables may vary in construction types based on the installation environment.
32 32  * **Geographical Metadata:** Parameters related to geographical location are specified for easy searchability in databases.
33 33  
34 -==== **2. Installation Environments** ====
47 +==== **3. Fiber Optic Cable** ====
35 35  
49 +* **Cable Composition:** Several optical fibers may be enclosed within one cable.
50 +* **Metadata Identification:** The metadata identifies each individual fiber used in the acquisition, including its intrinsic properties.
51 +
52 +==== **4. Installation Environments** ====
53 +
36 36  * **Shallow Burial:** The cable can be shallowly buried.
37 37  * **In-Conduit Installation:** The cable can also be installed within a conduit.
38 38  * **Water Installation:** Suitable for underwater environments.

40 -==== **3. Channels** ====
58 +==== **5. Channels** ====
41 41  
42 42  * **Sensor Distribution:** Channels represent sensors distributed along the fiber array at fixed intervals.
43 43  * **Physical Location Determination:** The physical locations of these channels are ascertainable through methods like tap tests and GPS tracking.
