The first website in North Korea, the web portal, was made in 1996. Efforts to establish the Kwangmyong network on a national scale began as early as 1997, with some development of intranet services in the as early as 1995. The intranet was originally developed by the Central Scientific and Technological Information Agency. The national Kwangmyong intranet was first in service during the early 2000s. North Korea's first email provider was, est.

Choose a distribution box when you need a compact enclosure for local wiring, equipment connections, or temporary power access. When setting up a power distribution system, many clients face a common dilemma: should they choose a distribution box or a distribution cabinet? The basic function of both is the same—to distribute power safely—but they are designed to suit different power demands and project complexities. You can simply understand them as follows: a "cabinet" is large and freestanding; a "box" is small and mounted on or embedded in a wall. The safest way to choose is not by product name alone. Despite this, it often ekes out an inconspicuous existence in the basement or utility room until something stops working properly or an extension becomes.

The dBm scale is logarithmic, meaning a small numerical change represents a large change in actual light power. This allows engineers to express a huge range of power levels, from microwatts to hundreds of milliwatts, using manageable numbers. Whenever tests are performed on fiber optic networks, the results are displayed on a power meter, OLTS or OTDR readout in units of “dB. ” Optical loss is measured in “dB” which is a relative measurement, while absolute optical power is measured in “dBm,” which is dB relative to 1mw optical power. Thus 1 mW = 0 dBm, 1 uW = -30 dBm, 1 nW = -60 dBm and two equal powers compared are 0dB (eg. power being the same, there is no loss. dB does not indicate how much power exists. At its core, the device consists of: The power meter does not evaluate. That is a measurement of absolute power, generally expressed in decibels referenced to a milliwatt of optical power (dBm).
