Cross-connecting box.
Conventional cable cross-connecting box operation principle is as shown in Figure 1, wherein IN optical fiber is fused to IN fusion points, OUT with IN tail optical fibers
Optical fiber is fused to OUT fusion points with OUT tail optical fibers, and jumping fiber both ends are separately connected an adapter, IN tail optical fibers and OUT tail optical fibers respectively
It is connect with adapter, optical circuit；When IN optical cables have remaining optical fiber, OUT optical cables will be directly connected to by directly melting mode.Jumping fiber two
End is adapter, and optical signal is caused significantly to weaken, and is unfavorable for the transmission of optical signal.
Blade inserting without jump optical cable distribution box operation principle as shown in Fig. 2, IN optical fiber and IN tail optical fibers are fused to IN fusion points,
OUT optical fiber is fused to OUT fusion points with OUT tail optical fibers, and IN tail optical fibers are connect by adapter with jumping fiber, the jumping fiber other end and blade inserting
Optical branching device is connected into fine end splitter IN end adapters, the optical fibre output end splitter OUT of OUT tail optical fibers and insert type optical branching device
End adapter connects, and IN end adapters and the OUT terminal adapter of blade inserting splitter pass through splitter IN end tail optical fibers and splitter
OUT terminal tail optical fiber is connected to, conducting light paths.Blade inserting is fitted without there is adapter at three to act on every light-path of jump optical cable distribution box
Orchestration, splitter IN end adapters and splitter OUT terminal adapter, at three adapter connection and the light splitting of splitter effect will compare
Conventional cable cross-connecting box causes optical signal by a larger margin to weaken, and is unfavorable for the transmission of optical signal.
Boxlike is divided into without jump optical cable distribution box as two kinds of transmission modes, and one of which operation principle is as shown in figure 3, boxlike
When the inlet side of optical branching device is tail optical fiber, IN optical fiber is fused to IN fusion points with IN tail optical fibers, and OUT optical fiber is fused to OUT with OUT tail optical fibers
Fusion point, IN tail optical fibers are connected with plug cassette splitter into the fine ends end splitter IN tail optical fiber by adapter and in-out end
It connects, OUT tail optical fibers pass through another adapter and the in-out end optical fibre output end splitter OUT terminal tail optical fiber with plug cassette splitter
Connection, conducting light paths, splitter IN end tail optical fibers and splitter OUT terminal tail optical fiber are separately connected an adapter, two adapters and
The light splitting effect of splitter will cause optical signal significantly to weaken, and be unfavorable for the transmission of optical signal.And another operation principle is such as
Shown in Fig. 4, when the inlet side of cassette splitter is optical fiber, IN optical fiber is with splitter IN end fused fiber splices in IN fusion points, OUT light
Fine to be fused to OUT fusion points with OUT tail optical fibers, OUT tail optical fibers pass through adapter and only fiber of the outlet with plug cassette splitter
Hold the connection of splitter OUT terminal tail optical fiber, conducting light paths, the light splitting of splitter that can weaken the light signal strength of user terminal.
