For Nigerian deployments, this product should be evaluated as part of the complete network path, including its connectors, mapping and acceptance values. 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 engineered for channels that specifically require APC at the MMC side and UPC at the MTP side. It cannot be considered interchangeable with the APC-to-APC version, even though the two products share the same fiber count and connector families.

Why the polish combination matters
APC and UPC end faces have different geometry and reflection behavior. They ought to never be forced together in a mating adapter. This jumper deliberately places APC on the MMC connector and UPC on the MTP Elite connector, which means the surrounding channel must present the matching APC and UPC interfaces. Checking the polish at every 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 cords. The two connectors are female and non-pinned, and factory jumper polarity controls the internal assignment. 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 completed product.
Ordering and installing the correct version
Standard choices are 1m (3ft), 2m (7ft) and 3m (10ft), plus customized lengths in feet or meters. Document this APC-to-UPC model distinctly in rack documentation to distinguish it from APC-to-APC cords. When fitting the assembly, inspect the ferrules, comply with the key orientation and keep the 7.5mm minimum optical-fiber bend radius around the MMC and MTP boots.
Ordering and Factory Support
Specify 24FMMCMTPOM4 and explicitly establish 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. For Nigerian orders, our team can check the requirement before coordinating manufacture and international delivery.
