Outside plant

For the application of fiber optic technology in the OutSide Plant sector (OSP) R&M offers a wide range of solutions to protect installed components against adverse environmental conditions. The modular concept even allows hybrid solutions for copper and fiber optic media.

Cross-connection cabinets
CCCs provide the outer casing for R&M components. Their housing is made of fiber-glass reinforced polycarbonate manufactured under the structural foam molding process. This guarantees outstanding mechanical strength for a low weight. The mounting frame is made of stainless steel. A solid door lock and high-quality locking systems protect the sensitive components against unauthorized access.

Fiber optic modules for CCCs
With its FiberCurb II product line R&M offers a solution for the low-attenuation connection and distribution of main and branch cables in traditional point-to-point or point-to-multipoint fiber optic network topologies in CCCs. The FiberCurb II module is designed for up to twelve fiber terminations which, depending on requirements, can be spliced onto the connector outlets or directly onto the patch cords. The modules can also be equipped with optical splitters. The handling of the cable management is uniquely safe and user-friendly. The module also guarantees minimum bending radii of 40 mm. The result: maximum operational reliability.

Splice closures
R&M’s FTTx splice closures for fine distribution in outdoor use – either above or below ground – accommodate up to 144 splice connections in a very confined space. Other features include: tool-free installation, gradual switch-on of connection cables and a closure system with long-term stability and reusable seals, complying with the requirements of protection index IP68. If necessary, the closure system can be sealed or fitted with a lock. Protecting cables against mechanical loads is particularly important when working outdoors. For this reason the FTTx splice closures are fitted with a special access ring that guarantees a neat tension relief. In spite of their compact design, the splice closures provide space for PLC splitters. Through the use of high-quality polyethylene the closure system is particularly resistant to alkaline earths, salt water, and fungal and putrid bacteria.

Small distributors
Venus Boxes are used in Fiber To The Building (FTTB) and Fiber To The Home (FTTH) architectures. They protect the network transitions against environmental effects and also constitute the handover point to the in-house cabling. The Venus Box was developed to withstand the toughest climatic conditions such as rain, splash water (IP54), heat and strong UV radiation. The boxes can also be equipped with splitters. What’s more, the Venus Box is suitable for hybrid applications.
