MMC to MMC 4-Port Fiber Optic Adapter/Coupler without Flange

This four-port MMC-to-MMC adapter places four mating positions in a single reduced-flange green plastic body. Measuring 12.9 x 17.5 x 29.6mm, it is designed for high-density MMC panels where shared mounting blocks save space and reduce the number of individual adapter installations. Fiber capacity depends on the MMC connector type used at each port.

Product Highlights

• Connector Type: MMC-MMC
• Body Style: 4-Port
• Color: Green
• Mounting Type: Reduced Flanged
• Body Material: Plastic
• Dimensions (HxWxD): 12.9x17.5x29.6mm

Four ports in one housing allow a panel to accommodate more MMC interfaces without four separate mounting operations. The 17.5mm body width must be matched to the correct cut-out, and front access should be checked with all four positions populated. MMC-12, MMC-16 and MMC-24 systems have different fiber maps, so port count alone does not define channel capacity.

Each adapter position is a separate mechanical mating point. The block does not join fibers between ports or provide polarity correction. Label the four positions clearly and document which trunk or jumper occupies each one. This is especially important when adjacent ports carry different fiber counts or connect to different destinations.

High density makes finger and boot clearance a practical concern. Confirm that a connector can be removed without disturbing the other three links. Inspect end faces before insertion, cap unused ports and avoid forcing misaligned connectors. The reduced-flange housing should be installed only in a panel designed for its mounting geometry and dimensions.

Quote part number 24245 for the four-port reduced-flange adapter and provide quantity. If these blocks will populate a new enclosure, include the panel cut-out and desired port numbering to verify fit and labeling before ordering.
