Crimplok™ Connectors
Quick, easy installation and superior
performance
To successfully design, install or operate today’s fiber
optic networks, you need components that offer
speed and reliability – from the fiber itself all the way
down to the connectors. That’s why 3M developed a
connector that combines the speed of non-adhesive
connectors with the performance characteristics
of epoxy and hot melt connectors. 3M™ Crimplok™
Connectors are the ideal solution for quickly making
fiber connections at the desk or for emergency
restoration work.
Crimplok connectors were designed to:
• Save time in installation
• Provide rugged, reliable performance, meeting or
exceeding current EIA/TIA-568B.3 specifications
• Install cleanly and simply with fewer parts and
tools
3M™ Crimplok™ ST Connector Multimode
Saves time
Available in both SC and ST, single-mode and
multimode connector versions, Crimplok connectors
are faster to install than epoxy connectors since
there is no set-up or curing time. Crimplok
connectors do not require special heating tools or
ovens, so time spent searching for electrical outlets
is eliminated. Polishing the connector is also a simple
process that can be performed in seconds.
Provides reliable performance
The Crimplok connector incorporates proven 3M
malleable metal element fiber gripping technology.
There is no fiber splice or second joint inside the
connector, so there is no added attenuation at the
connection.
When the conformable metal element closes, it grips
a length of the fiber, eliminating fiber movement
associated with other crimp-style connectors.
The strength of the metallic element ensures that
Crimplok connectors meet industry standards for
temperature and humidity.
The plastic buffer retention insert also prevents fiber
movement by gripping the buffer without crushing it
when the crimp ring is crimped. On jacketed cable,
the crimp ring also grips the Kevlar® strands and
3M™ Crimplok™ SC Connector Single-mode
cable jacket to prevent the fiber connection from
breaking when the cable is pulled.
The buffer retention insert and the crimp ring
combine to ensure that Crimplok connectors perform
extremely well and meet rigorous tensile strength
requirements in building wiring applications.
Installs cleanly and simply
Preparing and installing Crimplok connectors is as
simple as the concept behind them.
During installation, the fiber passes through the back
end of the connector, through the metallic element
and extends beyond the end of the activation tool.
Pressing the activation tool locking arm closes the
metal element around the fiber. It’s that simple.
The few tools required for installing a Crimplok
connector can be conveniently stored in a small tool
pouch.
