FOSC - Fiber Optic Splice Closures are a family of fiber optic splice closures utilizing heat shrink and mechanical cable sealing, for use in all fiber splicing applications in outside plant fiber networks. FOSC closures use mass fibre splicing and are normally only installed where future access to the fibers is not planned.
FOSC 400 closures are designed for “butt splices” of fiber cable. i.e. all cables enter one end of the closure and is thus suitable for splicing away from the manhole pit typically in a van. FOSC 400 B4 continues to be the most popular closure in the Irish market with over 3000 pces providing reliable service since it's introduction in 1999.
FOSC closures can be used with any type of cable for aerial, direct buried or manhole applications.
The main FOSC 400 family consists of three closures:
FOSC 400 D5- Up to 288F ( or 1728F if using Ribbon)
FOSC 400 B4- Up to 144F
FOSC 400 A4- Up to 48F
• How many cables will enter the closure?
• How many splices splices do you wish to store per tray? Trays have a capacity for 24 splices however some operators prefer to only store 12 splices per tray
• What size are the cables? (Diameter and number of fibers?)
• How many fibers will be spliced and how many expressed (uncut) through the closure?
