What is the difference between EYDFA and EDFA?
EYDFA and EDFA are both optical fiber amplifier, but they are quite different in structure, performance, and application scenarios. Below let’s expose them one by one. Differences in structure and working principle Characteristic EYDFA EDFA Doped element Er ³ ⁺+Yb ³ ⁺ co doped fiber Single erbium ion (Er ³ ⁺) doping pumping method Double […]
What should do if the attenuation of the fiber optic lines is too large?
Excessive attenuation of fiber optic lines is a common fault in Cable TV networks, and a graded treatment strategy should be adopted based on specific causes. The following is a systematic solution: Quick self inspection and basic processing (user can operate independently) Clean the fiber optic connector Wipe the fiber end face with a 95% alcohol swab […]
How to calculate the attenuation of fiber link in a Cable TV network?
In the Cable TV network, the attenuation of fiber link requires comprehensive calculation of fiber transmission, splitter distribution, and connection point losses. The specific calculation steps are as follows: Formula for Fiber Link Attenuation Composition Total attenuation (dB)=fiber optic transmission loss + splitter loss + active connector loss + fusion point loss Calculation basis for each sub item: Fiber optic transmission loss […]
