Ortronics LM4-LC24J-2A3UN 24-fiber Mpo to Lc Cassette OS2

Product Description

The ORTRONICS LM4-LC24J-2A3UN is an M4-series fiber optic cassette designed to terminate a 24-fiber MPO male trunk cable and break it out to LC duplex connections on the front. Built for OS2 single-mode applications, this cassette provides a clean, organized transition between MPO backbone cabling and LC patch panel ports inside an enclosure or rack-mount housing. Network technicians and low-voltage installers deploy this type of cassette in structured cabling systems where high-density fiber distribution is required. The quick-disconnect (QD) design allows the unit to snap into compatible M4 enclosures without tools, reducing installation time in dense rack environments.

This cassette is suited for single-mode OS2 fiber backbone infrastructure in commercial buildings, data centers, and campus networks. It is installed inside M4-compatible rack-mount or wall-mount fiber enclosures where MPO trunk cables feed from the backbone and LC-terminated patch cords connect to active equipment or distribution panels. The 24-fiber capacity makes it appropriate for high-density panels where consolidating fiber count per rack unit is a priority.

Key Features

• 24-fiber capacity with MPO male to LC duplex breakout configuration
• OS2 single-mode rated for long-distance, low-loss fiber runs
• Quick-disconnect (QD) mounting for tool-free installation in M4 enclosures
• MPO male connector on the rear interfaces directly with MPO trunk cables
• LC duplex ports on the front accept standard LC patch cords
• Sold as a single unit (each)

Compatibility

Designed for use with M4-series fiber enclosures and housings that accept quick-disconnect cassettes with MPO trunk interfaces. Specific enclosure model compatibility should be confirmed against ORTRONICS M4 enclosure documentation.

Installation Notes

Installation is typically performed by a licensed low-voltage or structured cabling technician. Before servicing active fiber links, disable or shutter all optical transmitters connected to the affected fibers to prevent exposure to laser light. The cassette should be inserted into the enclosure chassis until the QD latch engages fully. Follow TIA-568 and applicable local codes for fiber termination, labeling, and bend-radius requirements.
