-
High-Density Backbone: Engineered to interconnect cassettes, panels, or ruggedized MTP fanouts, rapidly deploying high-density backbone links in data centers.
-
Tailored to Your Facility: Fully customizable. Choose your exact length, polarity (Type B standard), and jacket rating (LSZH, OFNP, OFNR) to meet your structural blueprint.
-
Factory Direct Quality: Manufactured and tested in our advanced facility of 400-500 skilled professionals, ensuring massive capacity, rigorous 3D interferometry testing, and rapid global fulfillment.
Product Overview
The Wolontek Custom OM4 MTP-8 to MTP-8 Trunk Cable is the definitive backbone solution for next-generation data centers. Designed around the highly efficient Base-8 architecture, this multimode trunk cable provides a direct, uncompromised pathway for 40G, 100G, and 400G high-speed parallel optical networks.
Unlike traditional Base-12 cables that leave 33% of the fibers unused when connected to QSFP+ or QSFP28 transceivers, our Base-8 trunk cables ensure every single fiber is utilized, maximizing your infrastructure ROI. Whether you are patching between high-density MTP fiber adapter panels or creating a direct link between core switches, this custom trunk cable delivers carrier-grade reliability. Each assembly is factory-terminated, heavily tested, and built to your exact length specifications to eliminate airflow-restricting cable slack.
Key Features
-
100% Factory Tested: Every trunk cable undergoes rigorous 3D interferometer inspection and insertion loss/return loss testing to guarantee pristine signal integrity.
-
Bend-Insensitive Multimode Fiber (BIMF): Advanced OM4 50/125μm glass allows for tighter cable routing without inducing attenuation (7.5mm minimum bend radius).
-
Optional Pulling Eyes: For longer runs, we offer customized pulling eyes to protect the MTP connectors from strain and damage during conduit installation.
-
Rapid Deployment: Factory-terminated trunks dramatically reduce field installation time and labor costs compared to traditional field splicing.
-
Custom Polarity Options: Available in Type B (standard for 40G/100G parallel optics), Type A, or Type C to match your specific network polarity design.
