The new Push-Pull FO patch-cords and breakout cable assemblies are now equipped with optical connectors with a Push-Pull-Boot. Insertion and extraction of such connectors occur with a simple push or pull on a flexible and robust strain relief boot providing the highest functional density in the most dense fiber cabling environments. Another feature of these connectors is a polarity reconfiguration in the field while ensuring product integrity and performance. Push-pull system is available for Patchwork patch-cords and assemblies with LC Duplex Uniboot, MDC (VSFF – very small form factor) and MTP PRO optical connectors.
