The one-way links can be configured in other ways, both of those physically and logically, and also the network topology dictates the method through which one-way links and nodes relate to one another.

A semiconductor laser emits mild through stimulated emission rather than spontaneous emission, which leads to high output electrical power (~one hundred mW) together with other Gains relevant to the character of coherent light. The output of the laser Rungrong is relatively directional, permitting substantial coupling efficiency (~50%) into one-manner fiber.

[one hundred forty four] Even if there are numerous concerns arising from the use of CCTV like involving privacy,[145] more commercial establishments are still setting up CCTV systems in britain.
