The instrument interface is suitable for all standard 2.5mm plugs, and special plug specifications need to be notified in advance.

OP1021 can be equipped with two LED light sources, with wavelengths of 850nm and 1300nm. Built in 105/125 μ m. 0.22NA optical fiber meets most overflow testing applications.

near field

1. Near field (NF) represents the optical power density of the divergent light source end face or fiber tail.

OP1021 meets the requirements of IEC61280-1-4 and uses a pinhole scanning mechanism to obtain near-field distribution. Using a magnifying glass objective, the end face of the fiber is displayed as a plane. One with a diameter of 100 μ The pinhole of m is placed in front of the planar detector, and the projected image is mechanically scanned to obtain near-field distribution data.

3. Equipped with three software controlled positioners, OP1021 can move in three axial directions. One of them is used for image focusing (Z-axis), and the other two are used for center scanning of the projection plane (X-axis, Y-axis), with a scanning stroke of+/-250 μ m. Accuracy 0.1 μ m. This near-field analyzer can analyze the end faces and emission conditions of most optical fibers.

far field

OP1021 meets the testing requirements for far-field distribution numerical aperture within the TIA-455-177-B Technique 1 standard. The far field scanning of this instrument is achieved by moving the core diameter 100 μ Fiber optic implementation of m.

2. The running trajectory of the optical fiber is a semicircular arc along the radial direction from the end face of the incident optical fiber, while rotating the end face of the incident optical fiber in a radial motion. Receiver is 100/250 μ The m fiber is placed 5cm away from the end face of the incident fiber, with a movement range of -0.5 radians to+0.5 radians from the radial center.

3. Far field emission measurement can demonstrate the far-field emission of optical fibers. Using far-field scanning, the numerical aperture of the optical fiber can be measured under overflow emission conditions.

application

1. The OPL-LCA testing software is used in conjunction with OP1021, which controls all requirements for far-field and near-field scanning, and provides templates and annular flux for far-field and near-field emission.

2. Display far-field or near-field distribution curves in a user-friendly manner.

3. The user can set the stride of the far and near field transmission device to further meet the control of scanning accuracy and scanning duration.

4. Export the data to an Excel spreadsheet for further data analysis.

5. Use OPL-LCA software to directly print charts.

6. The circular flux calculation has the function of uploading circular flux templates with different emission conditions.
