CONNECTORS
MC3 MKII RANGE
The high performance MC3 MkII multiway connectors incorporate individually
insertable/removable optical contacts for easy assembly/maintenance. The
MC3 MkII range has the same removable alignment insert feature as the
MC3 for easy cleaning (which can be specified in either receptacle or plug),
and is suitable for use with most singlemode and multimode optical fibres
with core diameters from 5 to 200µm. 5, 8 and 12 optical channels are
accommodated in the MIL-C-38999 III style connector shells. The MC3
connector range has been tested and approved for use in severe environments.
THE MC3 IS USED ON THE FOLLOWING PROGRAMMES:
