Cabling Connection Types

The CDM-625A Advanced Satellite Modem uses a number of different cables. Each cable type is
typically dedicated to a specific mode of operation types – see Section 3.2.
1) Not all of these operational interface types may be available.
2) The European EMC Directive (EN55022, EN50082-1) requires using properly
shielded cables for DATA I/O. These cables must be double-shielded from end-to-
end, ensuring a continuous ground shield.

3.1.1 Coaxial Cable Connections

Coupling Type
Bayonet
(Type 'BNC' shown)
Threaded
(Type 'N' shown)
The types of coaxial cables used by Comtech EF Data are 'BNC', 'TNC', 'N', 'F', and 'SMA'. Coaxial
cables (plugs) and their mating connectors (jacks/sockets) are available in two coupling styles:
Bayonet or Threaded.
•
Bayonet Coupling Style: The jack has a pair of guideposts that accommodate the plug's
lockdown slots. This lockdown design provides secure assembly without over-tightening the
connection.
