FA-FSC-HO4, Aerial Fiber Optic Splice Closure For Ribbon Optical
Cable Maximum 288 Cores
Sealing of fiber splice joint closure is very important in the
actual project. Because the fiber surface is easy to produce micro
cracks if there is water or moisture in the splice closure and the
fiber will break for a long time, and the fiber splicing closure is
directly buried underground mostly, so excellent sealing is
necessary for the fiber splice joint closure.As for horizontal
type, The sealing of fiber cable joint closure is mainly included
two parts: the sealing between the optical cable and the
closure,sealing between the upper and lower cover plates. Before
sealing, it need to polish the cable outer sheath on the vertical
axial with gauze, so that the cable and the sealing tape can be
closer together and the sealing can be done better. The sealing
between the upper and lower cover plates should pay attention to
the sealing tape, it need to place evenly in the sealing groove and
the screw should be tightly screwed without gap.
Technical parameters of fiber optic splice closure:
1, Aging resistance: have good stability on heat, heat radiation,
air, ozone and so on.
2, Corrosion resistance: with strong resistance to dilute acids,
salts, oxidants, aliphatic hydrocarbons, etc..
3, Sealing technology: use seal components which can be open
repeatedly to ensure good airtight and waterproof performance.
4, Mechanical performance: able to endure harsh conditions such as
vibration, impact, fiber tension, distortion and strong temperature
changes.
5, Locking device: no special tools, easy for installation and
repeated opening.
6, Divergence function: provide various options like 2 inlet 2
outlet, 3 input 3 output, 4 inlet 4 outlet.
7, Splicing function: using stacked clamshell structure,does not
need to remove other fiber cassette during operation.
8, Other performance requirements are compliant with YD/T814.1-2004
standard.
