Currently on the market multi-channel digital videoconverter, involving a wide variety of technical indicators, most engineers and users also lack the appropriate means to determine the reasonableness and authenticity of the technical indicators, so it is easy to lose their way when choosing products.
Here are a fewindicators of theoptical transmitterparameters:
1 . Technical indicators to consider, there is enough video bandwidth, APL range is wide enough, signal-to-noise ratio (SNR), etc..
2 . Reliability considerations. Convenient power supply and wide power range. Power supply is to ensure thereliability of the digital videoconverteris the first element to consider, power supply can not guarantee reliable, reasonable, talk aboutthe reliability ofthe digital videoconverterhas become a moon in the water. Temperature and humidity adaptability. There are grounding considerations,
port protection and so on.
3 . Practicality considerations. Generous appearance, reasonable structure; rich interfaces, reasonable layout; the most important thing is that the meaning of the indicator is clear, easy to open and maintain the project. How to correctly recognizethe optical transceiver, and how to choose theoptical transceiverwe needhas become particularly important. Below we will brieflyfamiliarize ourselves with thenationalstandardsforoptical fiberand theimpact ofthe technical parameters onthe opticalfiber.
