Custom OM4 MTP®-8 to 4x LC UPC Uniboot Trunk Cable, Base-8
-
-
The Ultimate Base-8 Efficiency: Designed with 8 fibers to perfectly match QSFP+ and QSFP28 transceivers, ensuring 100% fiber utilization with absolutely zero “dark” (wasted) fibers.
-
50% Space Reduction: Advanced LC Uniboot technology consolidates two OM4 fibers into a single 2.0mm/3.0mm round jacket, drastically cutting rack congestion and optimizing thermal airflow.
-
40G to 10G / 100G to 25G Breakout: Seamlessly splits a single high-speed MTP-8 backbone into four discrete, highly manageable LC duplex channels for Top-of-Rack (ToR) patching.
-
Elite Optical Performance: Outfitted with premium US Conec MTP® connectors and bend-insensitive multimode fiber (BIMF), ensuring a strict Low Insertion Loss (≤0.35dB).
-
Factory Direct Agility: Manufactured in our advanced 400-500 employee facility. We provide exact custom lengths, precise breakout staggers, and rapid bulk fulfillment tailored to your data center’s exact footprint.

Product Overview
The Wolontek Custom OM4 MTP-8 to LC Uniboot Trunk Cable represents the pinnacle of high-density multimode cabling. As hyperscale and enterprise data centers migrate to 40G and 100G parallel optics, traditional Base-12 cabling leaves 33% of the fibers unused. This Base-8 trunk cable solves that inefficiency, providing a direct, 100% utilized pathway from your MTP backbone to four discrete LC duplex ports.
Furthermore, as port densities multiply, standard LC zipcord cables create unmanageable loops that block critical cooling airflow. This assembly eradicates that congestion by utilizing LC Uniboot connectors—housing two multimode fibers within a single, slim round cable. This instantly reduces LC-end cable bulk by exactly 50%. Built to your exact length and breakout specifications, it eliminates unnecessary cable slack, offering a pristine, professional, and thermally optimized installation.
Key Features
-
Uniboot Airflow Optimization: Maximizes patch panel real estate and improves cooling efficiency by allowing significantly more cold air to reach your servers.
-
100% Factory Terminated & Tested: Fully assembled and rigorously tested via 3D interferometry in our facility, eliminating the downtime and unreliability of field splicing.
-
Bend-Insensitive OM4 Fiber: Features high-grade 50/125μm bend-insensitive multimode fiber (BIMF) to maintain pristine optical power even in tight, 7.5mm routing radius scenarios.
-
Optional Pulling Eye: For long-distance trunk routing across facilities, custom pulling eyes can be integrated to absorb tension and protect the delicate MTP and LC end-faces.
-
Custom Breakout Engineering: Tell us your switch layout, and we will stagger the 4x Uniboot LC legs to perfectly cascade across your hardware ports without tangling.
