Key Features
- 288 cores on LC duplex — the highest-density drawer panel in the range: 288 fibers in 5U on high-density LC adapter rows.
- Full drawer access — every splice tray slides out for splicing and inspection, even at 288 cores.
- LC for density — duplex LC packing doubles the per-row fiber count of SC at the same rack height.
- Flexible tray loading — 12 or 24 fibers per tray to match cable construction.
- Deep 400 mm chassis — working room for large-count cables and slack.
- Rated −40 °C to +70 °C — covers unheated distribution rooms.
Where the SJ-OTB-M22 Fits
- Central distribution points — 288-fiber LC termination in 5U.
- FTTH central cabinets — maximum feeder-to-drop density with sliding access.
- Data center and PoP rows — high-count patching without a floor-standing frame.

Installation Notes
- Mount the panel in any standard 19-inch rack (5U); leave front clearance for the trays to slide fully out.
- Splice tray by tray: 12 or 24 fibers per tray, sleeves seated, slack coiled with controlled bends.
- Label each tray and port row before patching — at 288 fibers, labeling is the difference between a frame and a trap.
