Recent Project Highlights

Representative projects demonstrating our connector capabilities across different applications.

Data Center Migration — MPO/MTP Trunk Deployment

A North American colocation provider required 2,400+ MPO-12 trunk assemblies for a spine-leaf upgrade across three facilities. Molex supplied pre-terminated Base-12 trunks tested to IEC 61300-3-35, achieving average insertion loss of 0.12 dB per connection. The pre-terminated approach reduced on-site installation time by approximately 65% compared to field termination, and the provider reported zero link failures during the first 6 months of operation.

5G Small Cell Rollout — RF Connector Supply

A Southeast Asian carrier deploying 800+ small cells across urban areas needed N-type and 4.3-10 connectors rated for outdoor environments. Molex delivered IP67-rated connectors with measured VSWR of 1.12:1 at 3.5 GHz, validated through PIM testing at -153 dBc. The project required custom cable assemblies with lengths ranging from 0.5 m to 3 m, delivered within 12 business days from order confirmation.

Industrial Automation — Harsh-Environment Connectivity

A European process control integrator needed M12 X-coded connectors for Ethernet-based sensors operating in chemical plant environments at temperatures from -25 to +70 degrees C. Molex supplied IP68-rated connectors with gold-plated contacts, tested per MIL-STD-810H Method 509.7 for salt fog resistance. Production batch acceptance testing showed return loss exceeding 26 dB at 100 MHz across 100% of units.
