CB-03

Lets you connect coaxial cables with male BNC connectors on screw slides used in standard 10 or 20 modens Telebrás sub-racks. It consists of a cable of 30cm, where on one side there are two open lug type terminals, designed to fit in the screw rails of sub-racks for 10 or 20 modens.

Characteristics

It is used, for example, to connect G.703 interfaces at 2048kbit / s of the DM704S converters.
This adapter does not perform impedance switching and should be used with 75ohms interfaces.
On the other side of the cable, there is a female BNC coaxial connector for panel mounting. The connector body is made of insulation material, so there is no contact between the signals on the BNC and the panel.
DATACOM also offers the RB-01 ruler, which serves as a panel to accommodate up to 40 of these adapters. Thus, Tx and Rx cables can be arranged for the 20 slots of a 20 modens sub-processor.
