General description
Functional
The 21-180, Fiberoptic G.703 converter is intended to extend distance and galvanic
isolate the teleprotection equipment for substations connection to telecom network.
Fiber Optic G.703 Codirectional
The ITU-standard “G.703 64kbit/s codirectional interface” describes a galvanic
interface. This interface is for example commonly used by teleprotection equipment
for connection to telecom multiplexers.
The codirectional interface is transferred at one balanced pair for each direction.
21-180
The 21-180 converts the codirectional interface signals to a proprietary fiber optic
protocol.
Applications
The fiberoptic port of the ABB REL55x/56x , Line Differential Protection
Terminals, is directly connected to the fiberoptic port of 21-180. The 21-180 Codirport is then connected to a 2048kbps G.703 E1 multiplexer.
