High Quality T1 Cable Assemblies

T1 Cable Assemblies

T1 cables allow you to connect DSU/CSU to DDS lines.

Cablek's standard T1 cables are built with 22 AWG solid 100 Ohm oval T1 cable and are RoHS compliant.

These are custom made cables. Cablek stocks the necessary components to manufacture all configurations and lengths. Email us with your requirements.

 T1 cable is used with RJ-48 male connectors. The RJ-48 connector may look very similar to an RJ-45 connector found on a typical CAT-5 cable, but don't be fooled, they are very different in many ways. An RJ-48 connecter is fastened on to an STP (Shielded Twisted Pair) cable, not the standard UTP (Unshielded Twisted Pair) CAT 3,5 or 6 cable. An RJ-48 also uses a different pin out arrangement, voltage level, and line capacitance than an RJ-45.

• RJ48 Patch Cable with two shielded pairs for T-1 applications
• Unique, two-layer insulation system provides electrical performance required for T-1 pulse rates
• Shielding protects against EMI/RFI interference
• Premium RJ48 style plugs with 50-micro inches gold plating for maximum performance
