Model Number: SJ-L-DSL   

 
 

 

 

 

 

 
 
 
SJ-L-DSL is a network signal extension device, which 
consists of remote unit and local unit. It can transmit 
network signal via two-wire such as 

CAT5, telephone 

or coaxial cable, etc

. The distance can reach 

3,000m 

and max bandwidth can be up to 

148Mbps

Meanwhile, it also can transmit telephone signal 
when transmitting network signal (

adding

 

an

 

additional

 

splitter

). This device can be widely 

applied in network signal extending system, network 
security system, network information distribution 
system, network renovation and expansion systems, 
railway, urban traffic, mining and telecommunication, 
etc.
