Black Box Standard LC Duplex Fiber Adapter Panel with Ceramic Sleeves

The Black Box JPM455B-R2 is a fiber adapter panel that holds LC duplex couplers and drops straight into the standard cutout used in Black Box enclosures, cabinets, and most other rack-mount fiber housings. It gives network teams a clean, well-aligned pass through point for multimode links, thanks to ceramic sleeves that keep the fiber cores centered and the loss low.

Installation is simple. The snap in mechanism clicks into place without tools, so a technician can populate an empty enclosure or expand an existing patch field in minutes. Because the panel supports low-density layouts, it is a practical choice when you need just a few LC ports rather than a full bank of high-density adapters.

An IT manager setting up a small server room, a lab engineer building a test bench, or a campus network administrator who needs to extend a backbone run can all use this panel to finish the job quickly and reliably. The ceramic alignment sleeves maintain performance even after repeated mating cycles, which makes the panel well suited for environments where links are reconfigured or tested on a regular basis.

Whether you are adding a new fiber run, re-terminating an existing line, or building out a modular patch system, the JPM455B-R2 delivers the compatibility and durability you expect from Black Box hardware.

Highlights:

• Snap in design lets you install or remove the panel without tools
• LC duplex adapters support two multimode channels per port
• Ceramic sleeves keep the fiber precisely aligned for low signal loss
• Fits Black Box enclosures and most other standard fiber cabinets and patch panels
• Works well in low density networks where only a few LC ports are required
• Economical way to add or expand multimode fiber connectivity
