Fiber Optic Splice Closure, Fiber Optic Closure, Fiber Optic Joint
Box, FOSC,Cables Enclosures
Innovative design is an erect and horizontal type with one hinge in
one side and open in another side. It is the most reliable FOSC
with the simplest installation in the world. The FOSC is suitable
for protecting fiber cable splices in straight-through and
branching applications. Based on an advanced formula, the plastic
parts are made of injection-molded, high-strength engineering
plastic ABS or PC by numerical control equipment; therefore
effectively prevent products from aging caused by coldness, heat,
oxygen and ultraviolet radiation. The strong housing and main
components provide fire resistant, waterproof, and quakeproof while
protecting splices during pulling, compressing, and impacting,
bending, tensioning, axial tensioning.
It ensures long-term reliability and usage under ambient
temperature from -40℃ to +85℃
Purpose: aerial, direct-burying, wall-mounting, Pipeline laying way
external dimensions: 580mm*190mm*140mm （Horizontal type）
Weight: 4.5kg（Horizontal type）
Structure: open structure
Material: ABS/PC
Components: Seal tape, Insulation tape, Nylon tie, optical cable heat
shrinkable sleeve, mental hook, seal fittings, numeral bar,
retaining ring
Environmental temperature: -40℃ to +85℃
Atmospheric pressure: 70∽106KPa
Optic property: The spare fiber coiled in the fiber emplacing device; the fiber
connector won’t attenuate during the FOSC installation operation
period.
Seal Performance: After the closures are sealed, then pressurized up to 100KPa±5KPa
in water, immersed in 15 minutes, there are no air bubbles; Or
observed for 24 hours, there is no change of air pressure.
Re-encapsulation Performance: The closures are pressurized up to
100KPa±5KPa in water, immersed in 15 minutes, there are no air
bubbles; Or observed for 24 hours, there is no change of air
pressure after three times of repeat encapsulation
Voltage-resistance strength: Under the effect of 15kv/DC/1min, non-puncture, and no arc-over.
Insulation resistance2X104M
Maximum capacity: 96cores
Span-life: 30 years.
It is widely used for communication, network system, cabled T.V. of
CATV, the fiber optic cable by network
Uses and properties:
It is belonged to open structure airproof tie-in
system of machine pressure.
It is used for the protective connection between two
or more optical cables
Suitable for single core fiber optic cable and ribbon fiber optic
cable
Main Technical Indexes:
1.Airproof performance: Airing pressure inside box 100Kpa, pointer
immovability after 24 hours or no air bell within 15min when parked
in the common temperature
water.
2. Re-encapsulation performance: no change in the index of
air-proof performance after three times of repeat encapsulation
