gasket provide environmental seals that isolate
dust, moisture and EMI
■ Designed for round, multi-fiber jackets providing
improved fiber management
■ Standard MT ferrules which provide an industry-
standard interface with high density and reliable
performance
■ 19.05mm (.750") diameter receptacle features a
small footprint and similar size to industry standard
MPO connector
Features and Benefits
High-density Circular MT Cable Assemblies are
designed for critical, high-reliability applications
Molex’s rugged, high-density circular MT cable
assemblies are designed to meet requirements
mandated by telecommunication, military, medical and
many other industries. Utilizing the low-profile Circular
MT connector, these cable assemblies are designed
to meet or exceed the mechanical specifications of
traditional datacommunication and telecommunication
inter-chassis connections.
The Circular MT assemblies use a single MT ferrule
housed in a nickel-plated, metal-connector shell. Fiber
counts range from 12 to 72 fibers. The metal housing
and stainless steel push-pull locking ring provide a
more robust design than the current industry standard
MPO connector polymer housings and latches. The
MT ferrule is recessed in both the circular connector
and receptacle housings, providing an additional
improvement over traditional MT connectors. Recessing
the ferrule ensures it is scoop-proof, preventing
damage to the precise MT alignment pins and ferrule
endface during handling and mating of the connector.
The circular MT receptacle housing features a deep,
polarized mating cavity which will reduce alignment-
pin hole damage that may occur during the mating
process with traditional MT connector systems.
Molex’s circular MT cable assemblies offer a more
robust MT ferrule-based interface versus ribbon-
based optical interfaces, which have traditionally
been rectangular. This new design ensures improved
alignment benefits, increased pull strength and the
use of new round, ribbon-cable constructions. Circular
MT connectors will be sold only as terminated cable
assemblies.
Circular MT Cable Assemblies complement Molex’s
existing line of MT products. For more information on
