Kenyan network installers should begin with the actual mating interfaces and site fiber records before assigning this product to a link. The 24FMMCMTPOM4 jumper combines a 24-fiber MMC APC female interface with a 24-fiber MTP UPC female interface. This mixed-polish OM4 product is developed for channels that specifically require APC at the MMC side and UPC at the MTP side. It is never interchangeable with the APC-to-APC variant, even though the two products share the matching fiber count and connector families.

Why the polish combination matters
APC and UPC end faces have dissimilar geometry and reflection behavior. They should never be forced collectively in a mating adapter. This jumper deliberately places APC on the MMC connector and UPC on the MTP Elite connector; therefore, the surrounding path 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 leads. Both connectors are female and non-pinned, and factory jumper polarity controls the internal layout. The MMC side supplies at least 40dB return loss; the UPC MTP side is rated at 20dB minimum, with 0.35dB maximum insertion loss for the cable assembly.
Ordering and installing the correct version
Standard choices are 1m (3ft), 2m (7ft) and 3m (10ft), plus project-specific lengths in feet or meters. Define this APC-to-UPC variant plainly in rack documentation to distinguish it from APC-to-APC leads. During deployment, check the ferrules, adhere to the key orientation and retain the 7.5mm minimum optical-fiber bend radius around the MMC and MTP boots.
Ordering and Factory Support
Use 24FMMCMTPOM4 and explicitly check 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 variant. Project support for Kenya and East Africa is available to reconcile the ordered configuration with the intended installation.
