PC ABS Material 48 Cores Fiber Optic Enclosure 4 In 4 Out Horizontal Type
A FOSC is a protective, re-enterable housing used in fiber optic networks to provide a safe environment for splicing, branching, storing, and protecting fiber optic cables. Think of it as a rugged, weatherproof junction box for delicate fiber connections. The term "FOSC" is actually a brand name from CommScope (formerly from TE Connectivity / Tyco Electronics), but it has become a genericized term—much like "Kleenex" for tissues—used to describe many similar fiber splice closures from various manufacturers.

Features:
1.1 Protection: Shields fragile fiber splices and excess fiber (slack) from environmental hazards like:
1.1.1 Moisture and Water
1.1.2 Dust and Dirt
1.1.3 Extreme Temperatures
1.1.4 Mechanical Impact and Crushing1.1.5 Rodents and other pests
1.2 Splicing Point: It is the primary location where two fiber optic cables are joined together (spliced), either permanently (fusion splice) or with connectors (mechanical splice).
1.3 Cable Management: Provides an organized way to store and manage splice trays and the excess fiber loop, which is critical for future repairs or re-routing.
1.4 Access and Re-entry: Unlike a simple enclosure, FOSCs are designed to be easily opened and re-sealed, allowing technicians to add, remove, or repair splices throughout the network's lifecycle.
