Optical Round Ribbon Cable Assemblies Offer Greater Flexibility in Interconnecting
Optical Network Systems
Molex's MTP round jacketed ribbon cable assemblies
provide easier installation than traditional flat ribbon
cables in optical networks. System designers and
installers have found it difficult to route flat ribbon
cable in complex networks. The use of round ribbon
cables allows the installer greater flexibility when
routing multiple jacketed cables in dense system
networks.
Molex developed a patent pending transition sleeve
which maintains the routing features of the round
cable while allowing the cable to be secured to the
MTP connector. The primary benefit of the round
Features and Benefits
I
Round outer jacket is easily installed by end user
I
Flexible PVC outer jacket is able to bend easily
I
Plenum-rated meets system flammability
I
Ribbons encased in solid buffer core ensures
ribbon cable is realized with the use of multiple
ribbons within a single jacket. Stacked ribbons in
traditional flat jacketed ribbon cables are prone to
piston in relation to each other, causing attenuation in
longer cable assemblies. The round ribbon cable
prevents the “pistoning” effect by encasing the ribbons
in a solid buffer core, preventing them from moving.
Fiber counts up to 24 fibers are currently available
while development continues on the 48 and 72 fiber
versions.
