24cores MPO Female to 12x CS Duplex harness Cables assemblies
The 24-Core MPO to CS Harness Cable is an advanced, high-density fiber optic breakout assembly designed to bridge high-capacity MPO backbone infrastructure with next-generation CS (Converged Standard) transceiver interfaces. By transitioning a single 24-fiber MPO trunk into 12 duplex CS channels, this assembly maximizes port density, optimizes rack space utilization, and ensures seamless migration to 400G and 800G Ethernet architectures.
- Trunk Interface: Terminated with a high-precision 24-fiber MPO/MTP connector (Male or Female), featuring stainless steel guide pins for sub-micron alignment accuracy and low insertion loss.
- Breakout Interface: Fans out into 24 individual CS duplex connectors. The CS form factor delivers a 50% smaller footprint than standard LC duplex connectors, significantly enhancing front-panel port density.
- Cable Architecture: Utilizes robust 2.0mm tight-buffered breakout legs, providing superior tensile strength, crush resistance, and bend performance compared to standard 0.9mm fibers.
- Fiber & Jacket Options: Available in OS2 Single Mode (Yellow), OM3/OM4 Multimode (Aqua), and Wideband OM5 (Lime Green). The outer jacket complies with LSZH or OFNR/OFNP fire safety ratings.
- Strain Relief & Identification: Features a reinforced, molded breakout fan-out kit for optimal strain relief. Each 2.0mm leg is individually laser-printed with sequential numbering for precise traceability.

CS Connector’s Details
CS (Converged Standard) connector is an advanced Very Small Form Factor (VSFF) optical interface designed to overcome the physical limitations of traditional LC connectors in high-density environments. Featuring a compact footprint that is approximately 40% smaller than a standard LC duplex connector, the CS design effectively doubles the port density on front panels and patch panels.
Engineered for modern data centers, the CS connector utilizes a push-pull boot mechanism, which significantly improves usability and accessibility in tightly packed, high-density racks. A key innovation is its polarity reversal feature, allowing for quick and easy polarity switching without the need to re-terminate the fiber or twist the cables.
Delivering optical performance that meets or exceeds IEC and GR-326-CORE standards, the CS connector is the ideal physical layer solution for next-generation 400G and 800G Ethernet networks, AI/HPC clusters, and ultra-dense data center architectures where maximizing space and airflow is critical.
