Black Box Low-Density Singlemode ST Duplex Fiber Adapter Panel

The Black Box JPM450C is an adapter panel that lets you bring single mode fiber connections into any standard fiber enclosure without wasting rack space. It arrives with three ST duplex couplings already fitted, each lined with ceramic sleeves that protect the fiber and keep insertion loss low over time.

Because the panel follows a low-density layout, it is a smart choice when you need just a handful of ports in a telecom room, a lab bench, or a campus cabinet. Technicians can install it in seconds by snapping it into Black Box enclosures as well as most industry-standard patch panels, so it supports quick moves, adds, and changes without special tools.

Use the JPM450C to extend backbone runs, set up test circuits, or create a tidy cross-connect area where reliability matters more than port count. If your network later grows, you can mix this panel with higher-density options in the same rack, keeping the door open for future expansion while protecting the fibers you already have in place.

Highlights:

• Low-density panel that holds three ST duplex couplings
• Ceramic sleeves preserve signal integrity in single mode links
• Snaps into Black Box enclosures and most standard fiber cabinets
• Ideal for small builds or segmented work areas where space is limited
