Precautions for Connecting Fiber Bragg Grating Sensors to OFSCN FBG Demodulators

There are two ways to connect fiber Bragg grating sensors to OFSCN fiber Bragg grating demodulators:

1. Direct Insertion

Steps:

Align the FC/APC optical fiber connector of the fiber Bragg grating sensor with the FC/APC optical fiber adapter on the panel of the OFSCN fiber Bragg grating demodulator.
Insert the optical fiber connector into the adapter and tighten the connector nut by hand.
 

Precautions:

Be careful to align the connectors when connecting, otherwise it may cause poor optical fiber connection and affect the measurement accuracy.
Do not overtighten the nut, to avoid damaging the optical fiber connector.
Advantages:

Simple and convenient, no additional tools required.
Disadvantages:

It is not recommended to use it frequently in this way, because repeated plugging and unplugging of optical fiber connectors may cause problems such as dust and wear, which will affect the service life of the equipment interface.

2. Using Optical Fiber Jumper

Steps:

Insert one end of the optical fiber jumper into the FC/APC optical fiber adapter on the panel of the OFSCN fiber Bragg grating demodulator.
Connect the other end of the optical fiber jumper to the FC/APC optical fiber connector of the OFSCN fiber Bragg grating sensor through the optical fiber flange.

 
Precautions:

Be careful to choose an optical fiber jumper that matches the optical fiber connector type of the fiber Bragg grating sensor and the OFSCN fiber Bragg grating demodulator.
Be careful to align the connectors when connecting, otherwise it may cause poor optical fiber connection and affect the measurement accuracy.
When using the optical fiber connection flange, be careful not to overtighten it, to avoid damaging the optical fiber connector.
 

 

Advantages:

Long-term connection is more stable and reliable, which can avoid dust entering the optical fiber connector and prolong the service life of the equipment.
Different lengths of optical fiber jumpers can be used to facilitate the connection of OFSCN fiber Bragg grating sensors at different distances.
Disadvantages:

Compared with direct insertion, the connection steps are slightly complicated.
Additional optical fiber jumpers and optical fiber connection flanges are required.
Recommended Method

According to the comparison of the advantages and disadvantages of the above two connection methods, it is recommended to use optical fiber jumpers to connect fiber Bragg grating sensors and OFSCN fiber Bragg grating demodulators. This connection method is more stable and reliable, can prolong the service life of the equipment, and is convenient for connecting OFSCN fiber Bragg grating sensors at different distances.

Special Reminders:

No matter which connection method is used, the optical fiber connectors should be inspected regularly to ensure that the connection is clean and stable.
No matter which connection method is used, make sure to align the protrusion of the FC/APC optical fiber connector with the notch of the FC/APC optical fiber flange before inserting it.
Before connecting or disconnecting the optical fiber connection, be sure to disconnect the power of the OFSCN fiber Bragg grating demodulator; if it is not turned off, please avoid looking directly at the optical fiber connector to avoid damage to your eyesight.
