MMC-24 APC to MTP-24 UPC Jumper, 24 Fibers, OM4

The 24FMMCMTPOM4 jumper combines a 24-fiber MMC APC female interface with a 24-fiber MTP UPC female interface. This mixed-polish OM4 assembly is designed for channels that specifically require APC at the MMC side and UPC at the MTP side. It is not interchangeable with the APC-to-APC version, even though the two products share the same fiber count and connector families.

Product Highlights

• MMC Female to MTP® Female, 24 Fibers
• OM4 50/125µm, bend-insensitive fiber
• MMC insertion loss ≤0.35dB, return loss ≥40/20dB (MMC/MTP®)
• Jumper Polarity wiring scheme
• 2.5mm Plenum (OFNP) cable
• Standard length options: 1m (3ft), 2m (7ft), 3m (10ft)

APC and UPC end faces have different geometry and reflection behavior. They should never be forced together in a mating adapter. This jumper deliberately places APC on the MMC connector and UPC on the MTP Elite connector, so the surrounding channel must present the matching APC and UPC interfaces. Checking the polish at each end is as important as confirming 24-fiber compatibility.

One 2.5mm OFNP jumper carries all 24 fibers, reducing cable bulk compared with twelve duplex cords. Both connectors are female and non-pinned, and factory jumper polarity controls the internal map. The MMC side provides at least 40dB return loss; the UPC MTP side is rated at 20dB minimum, with 0.35dB maximum insertion loss for the assembly.

Standard choices are 1m (3ft), 2m (7ft) and 3m (10ft), plus custom lengths in meters or feet. Identify this APC-to-UPC model clearly in rack documentation to distinguish it from APC-to-APC cords. During installation, inspect the ferrules, follow the key orientation and preserve the 7.5mm minimum optical-fiber bend radius around the MMC and MTP boots.

Quote 24FMMCMTPOM4 and explicitly confirm the APC-to-UPC requirement, length and quantity. A simple port schedule showing the MMC and MTP mating interfaces will help prevent an accidental substitution with the APC-to-APC model.
