The FOSC name has been synonymous with excellence in sealing, fiber management, ease of use, and design flexibility since the FOSC 100 closure was first introduced in 1986. FOSC closures have always been engineered specifically for fiber optic applications; they are not modified copper closures.

The CommScope FOSC 450 products are fully mechanical butt-type closures used in the outside plant network when mass splice storage is the main requirement. They are available in 4 different sizes and are typically used as track joints.

CommScope's FOSC 450 gel drop seal solution provides an improved level of efficiency for adding flat drop fiber cables to a FOSC 450 B, B-Short (BS), C or D sized closure.

The in-line closure FOSC-500B is the environmentally sealed enclosure for fiber management in the outside plant network.

CommScope's FOSC sealing kits are used inall outside plant FOSC closures, sealing between multiple cables entering a single cable entry port.

The FOSC OPGW, part of the FOSC 400 closure family, is a single-ended closure system specially developed for use on the optical grounding wires of overhead electrical power lines. The closure is suitable for use above ground; it can be attached to high voltage towers, poles, walls or other support structures.

FOSC splicing trays are designed to store fibers and splices in a controlled way. The same proven fiber routing procedures can be used in all the network elements that accept FOSC trays.

Known as the FOSC 450 family of closures, this product line can be used in any environment and for numerous splicing applications.

Designed for fiber-to-the-home applications, the FOSC 450 A combines the features and benefits of the larger FOSC 450 closure into a smaller, more efficient footprint FTTH requires. Measuring just 8 inches diameter by 19 inches long, and with a capacity of 96 single splices, the 450 A is designed for use in any outside plant environment (direct buried, below grade, above grade, and aerial) and numerous splice applications (expressed, tap-off, branch and repair).
