Fiber Optic
MT and MTP / MPO Cable Assemblies
Features & Benefits
Applications
• Provides connectorized
interface for ribbon or
ribbonized fiber
• High density interconnects for:
- Telephony central office
and local loop
- Data communications
• Connector alignment is made
with precision alignment pins
• Fanouts to simplex fiber
connectors available
• Provides interconnect for
parallel optical transmitters
and receivers
• Low loss interconnect
• Push-pull mating of MTP* for
quick connections
• NTT compatible
• Consistent and repeatable
performance
Molex MT and MTP connectorized ribbon fiber cable assemblies provide reliable high performance interconnects of up to
12 fibers in a minimum footprint. The MT connectors utilize the precision molded NTT compatible ferrule that connects 4 to
12 fibers using bare ribbon or ruggedized ribbon cable. Alignment between mating ferrules is accomplished using 2
precision guide pins that are pre-installed in a designated male connector. Two holes in the female connector locate the pins
providing repeatable core to core alignment of the fibers. The MT ferrules are kept in the mated condition with the aid of a
spring clip.
The MTP assemblies utilize the same MT ferrules and package them in a push-pull keyed connector housing for quick and
easy connection using the MTP adapter. Guide pins in the male connector maintain alignment with holes in the female
connector while the adapter retains the connectors in the mated position.
Back reflection for singlemode assemblies is controlled by using an 8 degree angle polishing process. Fanouts to single
fiber leads connectorized with Molex industry standard SC, FC, and ST† connectors are available to interconnect with the
current installed base of transmitters, receivers and patch panels.
An "enhanced" version of the multifiber connector has been developed to provide a quick and reliable connection for multiple
optical fibers. The "enhanced" connector is a more precise NTT compatible ferrule, connecting the fibers using bare ribbon or
ruggedized ribbon cable. The "enhanced" version will incorporate the same footprint and alignment as the standard
MT/MTP.
This "enhanced" connector will solve customers needs for a high density solution with minimal insertion loss. The
"enhanced" MTP housing is yellow and the MT ferrule is keyed with a yellow line.
