Edible
salt, also called Table Salt or just salt, is a mineral, one of a very few mineral substance commonly
eaten by humans.
There are different forms of Edible Salt: unrefined raw salt, refined salt,
table salt or
iodized refined salt. It is a crystalline solid, white or
light grey in colour, obtained from sea water or from
rock
deposits. Sea Salt comes in fine or larger crystals. In nature, it
includes not only Sodium Chloride,
but also other vital trace minerals.
Edible rock salts may be slightly greyish in colour due to this mineral
content.

Purchase video optical transceiver three major points of attention
Digital Video Optical Multiplexer involves a wide range of technical indicators Many people do not know how to choose, do not know to change according to those factors to determine whether the various aspects of digital video optical transceivers are good or bad, then the following is mainly to tell you about our current Optical Products Should choose in accordance with these several aspects - technical indicators, reliability factors and practical considerations, then what are these aspects? Video Optical Terminals technical indicators to consider.
Multiple digital video optical transceivers can have multiple functions, and each type of function has corresponding technical specifications, such as video indicators, audio indicators, asynchronous data indicators, Ethernet indicators, and so on. Here, from the perspective of monitoring engineering, we will focus on the following two video indicators. Is the video bandwidth enough?
Whether the APL range is wide enough for reliability considerations
As a security monitoring project, equipment reliability should be the first consideration. The reliability of the equipment is the equipment manufacturer must consider when designing the product, however, some manufacturers may be unwilling to do or do not know how to do this work for some reasons. The reliability of the product can be roughly examined from the following points. Whether the power supply is convenient or not, the power supply name is not wide enough, and the temperature and humidity adaptability is not enough. Optical port protection measures are in place. Grounding considerations, in the security monitoring project, ensuring the equipment is well grounded is an important part of ensuring equipment reliability. Good grounding will benefit the device against surge surge, anti-static and lightning strikes, which can significantly increase the reliability of the device.
Video optical transceiver is a practical consideration
Each vendor should provide mature products to users and contractors, not research prototypes. Therefore, it must have practical considerations. When selecting a video optical transceiver, users and engineers can consider more from the perspective of the practicality of the device. First, practical issues are easily judged by users and contractors. Second, it is difficult to believe that manufacturers who can't do a good job can do a good job in the reliability and technical indicators of optical transceivers.
Examining the practicality of the product
The appearance is generous and the structure is reasonable. The interface is rich and the layout is reasonable. The meaning of the indicator light is clear, which facilitates the opening and maintenance of the project. Video can be up and down, networking is convenient. In short, the user should consider and compare the video optical transceiver's technical indicators, reliability, practicability and pertinence when selecting the equipment. According to the actual situation of their own projects to do a suitable program, and finally can find a suitable video optical transceiver.
