Fiber Optic Multi-Channel Connectors
FOMC
ITT Cannon's EOMC Series Fiber Optic connectors
are designed to meet the needs of military and
commercial customers who require a rugged envi-
ronmental multifiber field connector. The FOMC
combines features which provide the user with a
connector that will withstand rough handling and
weather extremes with features of elastomeric
cable and interface sealing, scoop proof interface
to prevent optical contact damage, removable front
insert for easy optical contact cleaning, anodized
shell finish, and
a tough, strong dust cap with
attaching stainless steel strap.
Hermaphroditic design means plugs will mate with
an identical plug as well as receptacles. The remov-
able insert assures correcting mating and alignment. In
the FOMC, ruggedness is combined with good
optical perfomance, rapid coupling and attractive
pricing. Another plus feature for ITT Cannon's
FOMC design is the fiber flexure chamber which
prevents tensile loads from being applied to the
terminated fiber. The chamber provides space for
surplus fiber in a service loop of sufficient lenght to
permit one retemination of one or more fibers in
the plug and cable receptacle without reterminating
the strength member at the same time. This versa-
tility is an ITT Cannon exclusive.
The FOMC 2, 4, and
8 channel connector are
available as a cable plug, and several receptacle
shell configurations. The 8 channel can also be used
with less contacts i.e. 6,4, or 2 channels. Sealing
State-of-the-art ceramic alignment tips on the contact provide maximum coupling performance - less than
plugs are supplied with the
8 channel connector
1.0 dB average coupling less.
when using less than the full complement of con-
tacts. This catalog provides complete ordering in-
formation on available shell types, contact layouts,
fiber and cable dimensional and mechanical param-
eters.
