why ask always for mtp and not "only" mpo connectors
DESCRIPTION
In an increasing market of preterminated fiber optic cables, this presentation warns End-Users to be careful in asking vendors to put MTP/MPO connectors and not only simple MPO connectors (cheapers) in fiber optic trunk cables. MTP is a patent of US Conec consortium, used by best cabling vendors as ORTRONICS-Legrand. For any additional support: [email protected]TRANSCRIPT

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
