Your Professional Manufacturer of Fiber Optic Patch Cord Cables since 2000

It has 4 types, APC, PC, UPC & SPC.

Generally, APC & UPC are the most common used in different field. APC models are widely used in radio and television and early CATV system. The pigtail head adopts an end face with an inclination (8 degrees), which is generally invisible, and can improve the quality of TV signal. The main reason is that the TV signal is modulated by analog light. When the joint coupling surface is vertical, the reflected light returns along the original path. Because the uneven distribution of the optical fiber refractive index will return to the coupling surface again, at this time, although the energy is very small, the analog signal cannot completely eliminate the noise, so it is equivalent to adding a weak signal with time delay on the original clear signal. It is shown in the picture as ghost. The inclination angle of the pigtail ribbon can make the reflected light not return along the original path. This problem does not exist in general digital signals.

UPC, Its attenuation is smaller than that of PC. Generally, the flange of equipment with special needs is FC/UPC. FC/UPC is used for fiber hopping in ODF frame and to improve the index of ODF equipment itself.

The receiving and transmitting wavelengths of optical modules at both ends of fiber optic patch cord cable must be the same, that is to say, both ends of the fiber must be optical modules with the same wavelength. Generally, the short-wave optical module uses multimode optical fiber (in orange color), and the long-wave optical module uses single-mode optical fiber (in yellow color ) to ensure the accuracy of data transmission.

Do not bend and wrap the optical fiber excessively in use, which will increase the attenuation of light in the transmission process.

After using each fiber optic patch cord cable, the connector must be protected with a protective sleeve. Dust and oil will damage the coupling of the fiber optic patch cord cable.

If the connector is dirty, it can be cleaned with a cotton swab dipped in alcohol, otherwise the communication quality will be affected.

1. Before use, the ceramic plug and the end face of the plug must be wiped clean with alcohol and absorbent cotton.

2. The minimum bending radius of optical fiber shall not be less than 150mm.

3. Protect the insert and the end face of the insert to prevent bruise and pollution, and timely wear the dust cap after disassembly.

4. Do not look directly at the end face of the optical fiber when the laser signal is transmitted.

5. In case of man-made and other irresistible factors damage, replace the fiber optic patch cord cable in time.

6. If the optical fiber network or system is abnormal, the troubleshooting method can be used to test one by one. When testing or removing jumper faults, you can do the on-off test first. Usually, you can use a visible laser pen to light the entire optical fiber link for judgment. Or further use the precision optical fiber insertion loss return instrument to test its various indicators. If the indicators are within the acceptable range, the jumper indication is normal, otherwise, it is unqualified
