Fiber Optical Modem/Optical Transceiver, RS232/RS485/RS422 to Fiber Optic Single Mode

RS - 232 / RS - 485 / RS - 422 serial fiber optic MODEM
 

Products overview: 

RS - 232 / RS - 485 / RS - 422 serial fiber MODEM, USES the industry standard design, the wall exterior design support - rail DIN standards guide installation, installation is simple. SC168 can provide the user with the RS - 232 / RS - 485 / RS - 422 serial port end-to-end transparent transmission. As a result of optical fiber transmission, the optical fiber transmission of optical signals, there is no electrical conductivity, and thus has a strong anti-interference ability, will not be affected by high voltage and lightning. 

Product features: 

Low automatic detection rate of serial port, discrimination and control data transmission direction; 

Low data transmission rate of 0 to 115.2 Kbps adaptive; 

Low adoption of advanced communication code clock recovery technique to realize in time, ensure signal integrity; 
Integrated optical transceiver module, the output optical power is stable and reliable; 

Transparent communication, users do not need any debugging, plug and play; 

Adaptive low specific interface technology, without having to switch Settings, arbitrary switching RS - 485 / RS - 422 interface; 

Where has the function of automatically detects the signal rate; 

Low RS - 485 signal zero delay automatic forwarding; 

Single-ended 9 v power supply, the other end of the 5 VDC -
DC power isolation 3000 v, without a serial port for electricity; 

Low signal transmission using 3000 v high speed optical isolation and pre-emphasis technology; 

Low communication distance is 3000 meters (9600 BPS); 

Low support 32 points polling environment (customizable 128 points); 

Interface with 1500 w surge protection, 15 kv esd protection; 

And 485/422 USES RJ45 interface forms, the COM to choose five terminal; 

Low installed support DIN - Rail guideway and plate.
