RS232 Fiber Modem Single Mode 1310nm

1. Description

This device is ba sed on FPGA which supports asynchronous RS-232 communication interface Fiber Modem. The device is the best choice of connecting to the remote terminal unit (RTU) to a host (HOST) or a distributed data acquisition system (SCADA) controllers with very high performance price ratio. Using ordinary multi-mode fiber effective communication distance is up to 4KM while using ordinary single-mode fiber effective communication distance up to more than 40KM. Serial port communication rate is up to 921.6KBPS. As a result of the fiber as a transmission medium you can completely avoid the threat to communication device under the adverse environment such as lightning surges and electromagnetic interference at the same time it saves investments of the original lightning surge protection devices that using copper .

2. Function and Characteristic

◆ based on self -copyright IC
◆ Have the ability to automatically detect the baud rate of serial port signal

◆ Automatically test the reason of the device matt is that the device is power off or E1 line is broken.

And then indicate on the LED

◆ Serial port interface lightning-protection reached IEC61000-4-5 (8/20μS) DM(Differential Mode): 6KV

Impedance (2 Ohm) CM(Common Mode): 6KV Impedance (2 Ohm) standard

◆ Support SNMP Network Management
◆ Serial channel can transmit adaptable serial data asynchronously 300-921.6Kbps baud rate
