Key Features

Engineered For Performance

Polarity Management

Key-up to key-down (Type A) and key-up to key-up (Type B) options enable correct polarity management across structured cabling systems following TIA-568 guidelines.

SC Footprint Compatibility

MPO adapters fit standard SC adapter panel cutouts, allowing direct installation in existing patch panels and cassettes without hardware modification.

12/24 Fiber Support

Compatible with both 12-fiber and 24-fiber MPO/MTP connectors, supporting parallel optics from 40G (SR4) through 400G (SR8) data center architectures.

Color-Coded Key Orientation

Black housing for standard key-up/key-down and green housing for key-up/key-up configurations enable quick visual identification and prevent polarity errors during installation.

Typical Applications

01

Data Center Spine-Leaf Cabling

MPO adapters in high-density cassettes and panels connecting 40G/100G/400G QSFP and OSFP transceivers in leaf-spine and mesh data center architectures.

02

MPO Patch Panel Systems

Pre-loaded MPO adapter panels for rapid deployment of structured multi-fiber cabling in colocation facilities, cloud data centers, and enterprise server rooms.

03

Network Testing

MPO adapters in test setups for verifying insertion loss, polarity, and continuity of MPO trunk cables and harness assemblies before deployment.
