MMC-24 APC to MTP-24 UPC Jumper, 24 Fibers, OM4
For Tanzanian site work, correct product selection should be followed by careful transport, connector inspection and retention of the fiber records. The 24FMMCMTPOM4 jumper combines a 24-fiber MMC APC female interface with a 24-fiber MTP UPC female interface. This mixed-polish OM4 unit is intended to serve channels that specifically require APC at the MMC side and UPC at the MTP side. It cannot be regarded as interchangeable with the APC-to-APC model, even though the two products share the identical fiber count and connector families.

Why the polish combination matters
APC and UPC end faces have distinct geometry and reflection behavior. They should never be forced jointly in a mating adapter. This jumper deliberately places APC on the MMC connector and UPC on the MTP Elite connector; thus, the surrounding link must present the matching APC and UPC interfaces. Checking the polish at each end is as important as confirming 24-fiber compatibility.
Twenty-four fibers in a compact route
One 2.5mm OFNP jumper carries all 24 fibers, reducing cable bulk compared with twelve duplex patch cords. Both connectors are female and non-pinned, and factory jumper polarity controls the internal map. The MMC side offers at least 40dB return loss; the UPC MTP side is rated at 20dB minimum, with 0.35dB maximum insertion loss for the supplied assembly.
Ordering and installing the correct version
Standard choices are 1m (3ft), 2m (7ft) and 3m (10ft), plus bespoke lengths in feet or meters. Identify this APC-to-UPC version visibly in rack documentation to distinguish it from APC-to-APC patch cords. When deploying the product, examine the ferrules, observe the key orientation and preserve the 7.5mm minimum optical-fiber bend radius around the MMC and MTP boots.
Ordering and Factory Support
Quote 24FMMCMTPOM4 and explicitly ensure the APC-to-UPC specification, length and number of units. A simple port layout showing the MMC and MTP mating interfaces will help prevent an accidental substitution with the APC-to-APC version. For Tanzanian deliveries, the order details should include any site identification needed by the installation team.
