Matters needing attention in the use of optical fiber jumper:
The receiving and decoding wavelengths of the optical modules at both ends of the fiber optic jumper must be identical, that is to say, both ends of the optical fiber must be of the same wavelength as the optical module, and the simple method is to adjust the color of the optical module to be consistent. In general, the short wave optical module uses multimode fiber (orange fiber), and the Naga Namihikaru module uses a single-mode optical fiber (yellow fiber) to ensure the accuracy of data transmission.
Optical fiber in use not excessive bending and winding, this will increase the light attenuation in the transmission process.
After the fiber jumper is used, it is necessary to protect the optical fiber connector with the protective sleeve. Dust and oil stain will damage the coupling of the optical fiber.
If the fiber joint is soiled, you can use a swab dipped in alcohol to clean, otherwise it will affect the quality of communication.
1, before use, the fiber optic jumper, ceramic insert core and plug end face must be wiped with alcohol and absorbent cotton.
2, the use of time fiber, minimum bending radius is not small, 150mm.
3. Protect the core and the end face of the plug to prevent bruising and pollution. Remove the dust cap in time.
4, when the laser signal is transmitted, please don't look directly at the optical fiber end face.
5, the emergence of man-made and other non resistance factors, damage should be promptly replaced damaged optical fiber jumper.
6, should read the instruction manual carefully before installation, and carry on the installation debugging under the guidance of the engineer of the factory or the dealer.
7, optical fiber network or system abnormal situation, can be tested by troubleshooting. Test or exclude fault jumper can make off test, can usually be on the optical fiber link lighting judgment using visible laser pen. Or further use of precision optical fiber insertion loss return instrument, test its various indicators, the target in the qualified range, then the jumper is normal, and otherwise it is not qualified.
