Product Overview
The Wolontek Custom OM3 MTP-8 to MTP-8 Trunk Cable is the smart, budget-friendly backbone solution for enterprise data centers migrating to 40G high-speed networks. Designed around the ultra-efficient Base-8 architecture, this multimode trunk cable provides a direct, uncompromised pathway for parallel optical networks without the premium price tag of OM4 glass.
For 40GBASE-SR4 applications with link distances under 100 meters, OM3 multimode fiber delivers identical performance to OM4 but at a significantly lower material cost. This makes our custom OM3 trunk cables the ideal choice for Top-of-Rack (ToR) to End-of-Row (EoR) connections within the same data hall. Every assembly is custom-built to your precise length requirements to eliminate airflow-restricting cable slack, and 100% factory-tested to ensure flawless plug-and-play deployment.
Key Features
-
100% Factory Tested: Eliminates the risks and high labor costs of field terminations. Every cable passes strict 3D interferometry and optical performance tests.
-
Bend-Insensitive Fiber (BIMF): Advanced OM3 50/125μm glass allows for tighter routing in congested server cabinets without inducing signal attenuation.
-
Classic Aqua Jacket: Encased in the industry-standard Aqua jacket for rapid visual identification of multimode fiber routes in mixed-cabling environments.
-
Optional Pulling Eyes: For safe and efficient conduit installation, custom pulling eyes can be pre-installed to protect the MTP connectors from pulling strain.
-
Custom Polarity: Available in Type B (standard for parallel optics direct connections), Type A, or Type C to match your specific network polarity design.
