FlexCore™ Front Access Fiber Optic Cassettes offer a wide range of deployment options for the
FlexCore™ Optical Distribution and Splice Frame. Cassettes are available with front MPO and
LC connectivity, with MPO connectors positioned on the right side or left side of the cassette
to simplify and optimize cable management within the frame. Splice cassettes with front LC
connectivity are available with bare 250 m or 12-ber ribbon pigtails. Cable entry points are
located on both sides of the cassettes to provide convenient cable routing options. Pre-terminated
tethered cassettes are available with 24-ber loose tube (non-ribbon) plenum or Euroclass B2ca/
LSZH cable pigtails of congurable lengths. A splice-only cassette with no front connectivity is
also available for direct cable-to-cable splicing within the frame.

FlexCore™ Front Access Fiber Optic Cassettes are used within the FlexCore™ Optical Distribution and Splice Frame to provide numerous options
for breaking out high ber count cables into smaller units for distribution throughout the datacenter.
