Application
SM 8F MPO- LC/SC/FC/ST Staggeredharness Cables are optimized for 40G QSFP+ PLR4 to 10G SFP+ LR optics direct connection and high-density data center applications.
OM3/OM4 8F MPO- LC/SC/FC/ST Staggeredharness Cables are optimized for 40G QSFP+ SR4 to 10G SFP+ SR, 100G QSFP SR4 to 25G SFP-25G-SR-S optics direct connection and high-density data center applications.
This 8 Fiber harness cable is used for a direct connection between QSFP+ to (4) SFP+ ports with no patch panels or intermediate trunks in between.
All of OMC’s MPO Connectors are from Senko/Nissin/Sumitomo. MPO Patch cable/trunk cable is a kind of high density cable assemblies which is generally use in three areas.
1, The Data Center application with high dense degree environment
2, The optical fiber to the building
3, The internal connector application in fiber equipment
