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

plugs are supplied with the 8 channel connector

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.
