Balun
ITT’s telecom baluns, for use in ITU G.703 applications, converts
between a 120 ohm twisted pair and a 75 ohm coaxial
transmission line.
These balun connectors have the transformer built into the body,
and can be quickly connected to screened or unscreened twisted
pair cables through IDC terminations, using a simple assembly
tool. The small size allows these connectors to be mounted on a
pitch of 10mm.
The balun is ideal for use where it is necessary to interconnect
equipment with 75 ohm coaxial outputs to a 120 ohm cable
distribution system. The balun is only a little larger than the
connector that it would replace.
