Circular MT Optical Cable Assemblies

High-density Circular MT Optical Cable Assemblies are designed for critical, high-reliability applications Circular MT ConnectorCircular MT Connector and Receptacle1-by-3 Circular MT Connector and AdapterCircular MT ReceptacleMolex’s rugged, high-density circular MT cable as-semblies are designed to meet requirements mandated by telecommunication, military, medical and many other industries. Utilizing the lowprofile Circular MT or 1-by-3 circular connectors, these cable assemblies are designed to meet or exceed the mechanical specifica-tions of traditional datacommunication and telecom-munication interchassis 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 MTP* and MPO connectors’ 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 1-by-3 circular MT connector housings utilize three MT ferrules in a nickel- plated, metal-connector shell. Fiber counts range from 36 fibers up to 72 fibers by using either 12 or 24 fiber MT ferrules. The1-by-3 circular MT connector housing uses a stainless-steel, locking mechanism to provide a robust connection. The circular MT receptacle and 1-by-3 circular MT adapter housings feature a deep, polarized mating cavity which will reduce alignment-pin hole damage that may occur during the mating process with traditional MT connector systems. The circular MT receptacle housing uses a jam nut for mounting versus the 1-by-3 circular MT adapter that is flange mount with screws. The shutter designed for the 1-by-3 adapter provides laser eye safety and has passed the TP-91 dust test specification.

Molex’s circular MT cable assemblies offer a more robust MT ferrule-based interface versus ribbon-based optical interfaces, which have traditionally been rectangular. The circular MT and 1-by-3 circular MT products ensure 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.
