High-Density MT Ferrule Optical Cable Assemblies Extend Space and Cost
Savings Up to 72 Fibers
With the addition of the High Density MT (HDMT) ferrule optical cable assembly line, Molex further strengthens
its position as a leader in optical backplane and front panel interconnect solutions. These cable assemblies offer
multiple space-saving options on the front panel by using the 72-fiber MT ferrule in the industry standard MTP*
connector, as well as high-density panel-mount Array connectors. In addition, by incorporating the HDMT
ferrule in the HBMT™ backplane interconnect, customers can benefit from the highest-density blind-mate
interface in the industry.
These HDMT ferrules extend the capabilities of traditional MT-style connectors beyond 12 and 24 fibers, making
configurations up to 72 fibers possible. Molex has developed termination and polishing capabilities achieving
insertion-loss levels that are comparable to those of 24-fiber terminations.
This significant increase in fibers in a single connector offers considerable space savings, along with reduced
installation time and cost. Molex is developing flexible ruggedized trunk cabling solutions that utilize the HDMT
ferrules, which are designed to reduce fiber installation costs in central offices and data center applications. Low
profile, high fiber count trunk cables streamline the routing of the trunk cables and reduce the number of fiber
pulls.
Features and Benefits
■
Up to 72 fibers in the traditional MT Ferrule
footprint increases density without increasing
front panel real-estate
■
Standard MPO/MTP connector interface ensures
industry compatibility
■
Optical Insertion Loss below 1.0dB across all 72
channels meets industry expectations
Bare ribbon breakouts ensure smooth transition
from 12-fiber transceivers to 72-fiber MTP on the
front panel
Jacketed 72-fiber cable assemblies are capable of
rugged chassis-to-chassis interconnects
