MPO to LC OM4 12-fibers (12fo) fan-out patch cables, often called harness cables, are designed to connect high-density MPO backbone trunks or transceivers (like 40G/100G QSFP+) to standard 10G LC ports. These cables typically feature a single MPO connector on one end that fans out into 12 individual LC connectors (often 6 duplex pairs) on the other. They are frequently installed in MPO MTP high density modules for patch panels.
40G/100G to 10G/25G Migration: Smooth transition paths for network speed upgrades.
Direct Device-to-Switch Connectivity: Secure linkage from transceivers straight to switches.
Backbone-to-Device Routing: High-speed backbone infrastructure connection.
High-Density Patching: Optimized space utilization within server racks.

1. What is the difference between OM4 and OM3 fiber for MPO-LC cables?
OM4 is laser-optimized 50/125μm multimode fiber with higher bandwidth capability than OM3. It supports 100G Ethernet up to 100 meters, making it ideal for high-speed network infrastructures and future-proofing data centers.
2. When should I choose Type B (Crossover) vs. Type A (Straight-Through) polarity?
Type B polarity is the industry standard for 40G/100G direct connectivity between devices (like transceivers). Type A is typically selected when integrating the cabling configuration through structured patch panels.
3. How do I determine if I need Male or Female MPO connectors?
Male connectors feature alignment pins, while Female connectors do not. Most QSFP/QSFP28 transceivers require Female (no-pin) connectors for a safe and correct match.
4. What jacket options are available and which one do I need?
We offer LSZH (Low Smoke Zero Halogen) jackets for safety in areas with low ventilation, and OFNP (Plenum) jackets which offer high flame-resistance for cabling routed through air ducts or plenum spaces.
5. Are these harness cables tested before shipping?
Yes, 100% of these cables are factory terminated and tested before shipping to guarantee optimal performance, low insertion loss, and reliable signal integrity.
