The RLH Optimum 4RU fiber patch panel is part of a series of fully integrated fiber distribution systems. The user friendly design makes the Optimum series the superior solution for fiber patching and/or splicing optical fiber in a 19/23” rack. It holds up to 8 fiber adapter plates (up to 192-fibers), 8 splice trays, and is ideal for installation in a wide variety of environments including substations, equipment rooms, central offices, and outdoor enclosures.

Optimum Series patch panels are constructed from powder coated aluminum alloy, and feature a removable hinged powder-coated aluminum door with quarter-turn cam-lock, removable slide out tray, and removable rear access self-sealing entry grommets. Optional strain relief kits featuring Peel n’ Seal technology provide proper routing and securing of fiber optic entrance cables at the rear, from above, the side or below.

Fiber assemblies or pigtails can be custom ordered and pre-terminated into the patch panel for a complete turn-key solution. The patch panels, splice trays and adapter plates may also be ordered separately. The plates are held securely in the housing with push-pull retainers that require no tools.
