MTP Overview

What is an MPO Connector?

The MPO connector family is defined by IEC-61754-7.

The MTP multi-fiber connector is US Conec’s trademarked name for our MPO connector. The MTP connector is fully compliant with IEC-61754-7; therefore it is an MPO connector.

While there are many MPO connectors on the market (Furukawa, Sumitomo, Fujikura), the MTP parts are distinctly different. The MTP connector is a high performance MPO!

MTP Overview

Spring

MTP oval spring provides more ribbon clearance; enhances

mechanical performance.

MPO round spring allows less ribbon clearance;

limits mechanical performance.

MTP Overview

Floating Ferrule

The MT ferrule can move freely inside the MTP housing while mated. This protects it from strain during side load.

SummarySummary

• Color coding by fiber type

• Removable housing for gender change and rework

• Metal pin-clamp to prevent pin transfer

• Recessed pin clamp to prevent spring-ribbon contact

• Oval spring for more ribbon clearance

• Increased ferrule float for improved mechanical performance (US patent # 6085003)

• Elliptical guide pin tip for improved durability via less guide-hole wear (US patent pending)

• Connector kits for jacketed cable, ribbon, and board applications (45% footprint reduction) available
