Optipack harness system (LC-LC)
Optipack harness systems (LC-LC) are used as pre-connectorised backbone links between cabinets in the data center. Generally, trunk harnesses will be connected to the rear side of patching modules and LC jumpers will be used as equipment cords to servers and switches. Backbones are generally deployed with singlemode fiber because only this fiber offers a future-proofed infrastructure for higher data rates. Multimode LC trunk harnesses are not recommended because LC multimode connectors do not offer an upgrade to 40G or 100G over parallel optics.
