MMC-24 APC to MTP-24 UPC Jumper, 24MMC-24 APC to MTP-24 UPC Jumper, 24 Fibers, OM4
Singapore high-density designs should assess this item together with panel access, cable routing and the complete optical loss allowance. 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 optimized for channels that specifically require APC at the MMC side and UPC at the MTP side. It must not be treated as interchangeable with the APC-to-APC variant, even though the two products share the corresponding fiber count and connector families.

Why the polish combination matters
APC and UPC end faces have differing 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; consequently, 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 mapping. The MMC side features at least 40dB return loss; the UPC MTP side is rated at 20dB minimum, with 0.35dB maximum insertion loss for this optical assembly.
Ordering and installing the correct version
Standard choices are 1m (3ft), 2m (7ft) and 3m (10ft), plus lengths built to order in feet or meters. Specify this APC-to-UPC variant in a clear manner in rack documentation to distinguish it from APC-to-APC leads. While the work is carried out, 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 review 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 variant. Singapore and regional project orders can be reviewed for interface compatibility, packing details and delivery coordination.
