JTOPTICS® Ultra high density MPO cassette features one rear 12-fiber MPO ports connection and 12 LC ports in front. This MPO fiber cassette is designed to upgrade existing LC links to SR4 parallel optics without wasting any of the fibers inside the cable, and it is ideal to deploy a Base-8 connectivity solution for use in main, horizontal and equipment distribution areas. JTOPTICS MPO Cassette Modules reduce the overall cost and setup time for complex high-density networking used in data center application.Ultra-High density pre-terminated fiber optic systemComplied to ANSI/TIA-568-C.3, IEEE 802.3ba and adheres to ANSI/TIA-942Ultra Low Insertion Loss and high return lossAluminum alloy shell protect the inner fibers effectively.High-quality MPO connectors Universal Polarity design suitable for Type-BPre-terminated Rear 12-Fiber MPO Adapter Pre-Terminated Front Multi-Mode LC AdaptersPre-Installed Multi-Mode MPO-LC Fan-Out CableCompatible with Ultra High Density UHD ODF..
