Confidential and Proprietary Information of ZTE CORPORATION
Take following steps to make coaxial connector on DDF side.
i.
Strip cable covering about 0.55 inch (14 mm).
ii.
Slip cable connector sheath, heat-shrink tube and crimping tube in
sequence. Open shielding net with a net opening sleeve or by hand.
Strip internal insulation layer to expose 0.11 inch (2.5 mm) of
internal conductor.
iii.
Insert core into plug. Insert core wire into soldering pin at back of
inner conductor and solder it. Trim shielding mesh with 0.23 inch (6
mm) crimping tube.
iv.
Push crimping tube and shielding net into connector tail.
v.
Use crimp pliers to crimp the crimping tube into a regular
hexahedron. Crimp twice in different angles.
vi.
Slip the heat shrink tube onto crimped tube; heat it with an air
blower to make it shrink, and screw the tail cover.
Trunk cable test
Solder, connectors internal conductors at both ends and coaxial
cables inner conductors leaving no dry joint. Ensure not to short
internal and external conductors.
Trunk Cable Conversion
Implement conversion from 75 Ohm to 120 Ohm trunk cable according to
specifications provided by ZTE. One converter serves as one E1 cable. 75
Ohm trunk cable uses BNC connectors and 120 Ohm trunk cable uses
8P8C Ethernet cable sockets.
Impedance converter
