Fiber Splice Closure FOSC-400 A8 is used to connect the distribution cable and the incoming cable, is widely applied in communication, network systems, CATV cable TV and so on. It adopts scientifically formulated engineering plastic and be shaped by injection molding, with anti-aging, anti-corrosion, flame retardant, waterproof, anti-vibration and anti-shock effects. Can effectively prevent the optic fibers from the influence of outdoor environment.
Fiber Splice Closure FOSC-400 A8-with dome-to-base design; up to 6 pieces splice trays, hinge for access of any splice without disturbing others trays; Fast and reliable sealing performance, easy to package multiple times. With lightning protection grounding device, it can be applied in overhead, wall mounting or directly buried.
The Fiber Splice Closure FOSC-400 A4/A8 is the smallest in the FOSC 400 series. It is intended for low fiber-count cable splices and “tap-off” splices. Tap-off splices are those where most of the fibers in a cable are ‘expressed’ uncut through the closure. Only a few fibers are cut and re-spliced to feed a building or Optical Network Unit (ONU). The FOSC 400 A4/A8 closure comes ready to store expressed loose buffer tubes. An optical slack storage basket is available for expressed stranded fiber and ribbon fiber. As with all FOSC 400 closures, the slack storage and splice capacity of the FOSC 400 A4/ A8 depends on factors such as cable construction, splice type and slack fiber lengths. Refer to the Closure Capabilities chart for more details.

The FOSC name is synonymous with excellence in sealing, fiber management, ease of use and design flexibility. The original FOSC 100 was introduced in 1986 and has held a leadership position since that time.
Fiber splice closures FOSC-400 are engineered specially for fiber-optic applications. They are not modified copper closures and the difference shows. FOSC clients ask for and get the highest quality standards. FOSC 400 closures combine proven fiber management hardware from the earlier FOSC 100 closures, with a completely new sealing system. Base-to-dome seals on FOSC 400 are mechanical for ease of installation and re-entry. Cable seals feature a new heatshrink sleeve and hot melt adhesive system that is installed with a hot-air gun. Common materials, accessories and practices are used throughout the product line to simplify training, reduce inventory and enhance productivity. FOSC 400 fiber optic splice closures are available in three sizes: the FOSC 400 A, FOSC 400 B and FOSC 400 D. All sizes are designed for use with any cable construction (loose buffer tube, central core tube, loose fiber, ribbon), in any environment (aerial, pedestal, buried, handhole, manhole) and for numerous splice applications (expressed, tap-off, branch and repair).
