KMCB Series Unshielded Mobile Couplers 

HCI's KMCB Series coupler boasts a slim profile, designed to be placed seamlessly within horizontal cabling as a junction point between two segments of solid cables or as an extension point after the wall outlet. But not all couplers are up for the job when it comes to bridging patch cords. The reason is simple: when a female RJ-45 meets a male plug, electromagnetic coupling can occur, disrupting signal integrity due to impedance mismatches. And when both sides involve an RJ-45 and a plug, it gets even worse.

Enter HCI's KMCB Series, which features a patented mechanism and a balanced circuit design that effectively keeps crosstalk in check, ensuring everything meets the required standards.

Cut the Crosstalk with Patented Contact Set
While couplers make patching two cords easier than dealing with twisted pair cable punch-downs, the only downside is they often degrade signal integrity in the cabling channel. But HCI’s KMCB Series is something else. Featuring a PCBA with patented impedance-matching technology (U.S. Patent 9391405 B1), it maintains impedance balance to minimize Return Loss and compensates for coupling effects that cause Near End Crosstalk.
Serving as a Junction Point within 90m
Sometimes, you need a longer cable run, but don't have the right length in one piece. In this case, patching two cables together is the solution. HCI’s KMCB mobile-style coupler is designed for just this scenario. All you need to do is terminate the field-terminable plugs on both cables, then connect them with the KMCB coupler. The outcome is virtually no signal loss, making it seem like the coupler isn’t even in the line.
As an Extension at Work Area
After the contractors have completed the permanent link installation, their job is essentially done. Users can simply plug in the specified patch cord to connect their computer or laptop. While patch cords are often kept short for visual appeal, sometimes you need a little extra length to extend your network. The HCI KMCB Series offers the perfect solution, providing the freedom to place the coupler wherever necessary without sacrificing transmission performance.
PoE Type 4 Ready
There are times when you need to patch two patch cords to extend your PoE cabling, and the first thought that comes to mind is, "Will this additional connection weaken the power from the PSE?" With HCI’s KMCB Series mobile-style coupler, that’s never an issue. It’s ETL certified for IEEE 802.3bt PoE Type 4, ensuring up to 90W of power delivery and adhering to IEC 60512-99-002 standards for mating durability, reliably handling 55V and 2.0 amps on each conductor.
Made in Taiwan
Besides the IT room, mobile-style couplers are often positioned to blend into visible spaces within commercial or residential buildings. Designed and made in Taiwan, HCI’s KMCB Series offers a perfect balance of form and function. Its elegant, streamlined look complements your office or home setup, while still delivering superior crosstalk protection. Trust KMCB to extend your connections with style, wherever you place it.
