The year of 1999, baking-free brick have been put forward in the first time, by Shine machinery. People in construction industry all wish to know more about baking-free brick, which is the trend of society development. The reason of the widely use for baking-free brick, is the 3 big difference compared with baked brick, as follow: Baking-Free Brick Making Machine,Environmental Brick Making Machine,Baking-Free Clay Brick Making Equipment,Baking-Free Clay Brick Making Machine Shandong Shenghuai Trading Co., Ltd. , https://www.shinebatchplant.com
1, additional loss optical splitter to the input optical signal in accordance with the predetermined split ratio for each branch is allocated, the optical signal through the optical splitter in addition to splitting loss, there are optical splitter itself to the optical signal The loss is called the optical splitter additional loss.
The additional loss is the most basic technical indicator of the splitter, and it has intrinsic links with other performance indicators. Therefore, the additional loss is not only a measure of the optical performance of the device, but more importantly it is also intrinsically linked to the device's seismic performance, temperature stability, and lifetime. For this reason, when we use optical splitters, we must strictly screen this indicator for manufacturers.
2. Ratio of optical power splitting ratio of optical splitter to each branch optical power is called splitting ratio, which is defined as the ratio of the output optical power of an output end of the optical splitter to the total output optical power of the output end of the optical splitter. .
This indicator is the most important design index parameter of the optical link and is explained in detail later.
3. Deviation of spectroscopic ratio The spectrophotometric deviation refers to the deviation between the actual spectroscopic ratio and the design value when the splitter is manufactured. This deviation makes one light increase and the other light decrease. Essentially it does not affect the total output power.
Because the distances from the transmitter to the optical nodes are different, in order to ensure that the received power of the receiver is consistent, the splitter ratio of the splitter should correspond to the transmission distance. That is, the longer the transmission distance is, the larger the ratio of the splitting light to the optical path is. If there is an error between the actual splitter and the designed split ratio, the received power at the receiving end will be inconsistent. At present, domestic manufacturers are fully capable of controlling the split ratio error of 1Ã—N optical splitter within Â±0.5%.
4. Divided light loss Divided light loss: The loss of the optical signal generated by different splitting ratios is called splitting loss. Its value is -10 lgK (K is the splitting ratio).
5. Insertion Loss The insertion loss includes two parts: the splitting loss and the additional loss, that is, the insertion loss (dBm) = -10 lgk + additional loss.
Baking-free brick(block): Choose the construction waste, stonework waste, fly coal ash, dry slag, boiler slag, etc to make the brick.
Baking-free brick(block): A concrete block making machine cost less investment while maximize the capacity of the brick making mahcine.
3.Influence for environment baking-free brick(block): Use the waste to make the brick, eco-environment. Baked brick(red brick): Use earth, make a sharp drop in farmland, baking will release the CO2, will exacerbate global warming, ozone hole, more and more all humans will expose in ultraviolet ray(UVA), it's no life lives under UVA. The Chinese government have issue the policy to use concrete brick replace the baked brick. Many city forbidden the usage of Baked brick.
