First, use 

 Boshi invented and pioneered electronic Ethernet / serial optical converters, but also the world's only Ethernet / serial fiber optic converter. Boshi electronic OPET232L1 Ethernet / Serial converter with common fiber optic network communications for Ethernet fiber converters are not the same. Boshi OPET232L1 can become a local Ethernet port virtual COM port (COM1-COM256), rate of 2400,4800,9600, ... ..., 115200bps. Common Ethernet fiber optic converter transmission is TCP / IP protocol of the signals, their rate is 10M/100M/1000M. The TCP / IP communication protocol data every frame is too long, relatively speaking, the key is real poor. Boshi Electronics Ethernet / fiber optic converter serial RS-232 serial port thanks to the communication protocol so more suitable for industrial measurement and control of optical fiber communication. 

 Boshi electronic OPET232L1 is the latest generation of Ethernet fiber optic communication products, directly from the Ethernet port, a pair of fiber optic transceivers convert the first serial signal for transmission, your serial devices via Ethernet and fiber access INTERNET! And power from the USB port. Boshi OPET232L1 Micro Ethernet / Serial converter with ultra-small optical form (74 * 23 * 47mm), can become a local Ethernet port virtual COM port (COM1-COM256) after transmission through the fiber, no need to change existing serial communication software. Drivers with Boshi ETH232GL1 Series Ethernet / Serial converter. As OPET232L1 or serial signal transmission, it must be in pairs or with Boshi the OPT series serial / fiber optic converter pair used. As a result of optical fiber as a communication transmission medium, with isolated high voltage, electromagnetic interference, transmission distance and so on. OPET232SL1 single-mode fiber transmission medium, OPET232L1 the transmission medium for the multi-mode fiber, but the shape and the drivers are exactly the same.
