RS232C signal ⇔ optical conversion for extended transmission distance, lightning protection, and noise reduction!
It is an RS232C signal ⇔ optical converter. By utilizing optical fiber, it enables long-distance transmission. It can be used for noise countermeasures in FA applications and lightning protection in outdoor wiring with optical fiber. <Features> ■ Extension of RS232C signal transmission distance Optical transmission of up to 40 km is possible. Please select the optimal model according to the transmission distance. ■ Wiring using optical fiber ・Noise countermeasures for FA applications ・Lightning protection for outdoor wiring <Applications> ・RS232C signals are affected by noise, causing malfunctions. ・The standard length is insufficient for connecting RS232C ports. ・I want to transmit 232C signals outdoors but am afraid of lightning.

basic information
1. Modulates RS-232c signals to enable long-distance transmission over optical fiber. By utilizing optical fiber, it avoids troubles caused by noise and lightning protection measures. It supports H-PCF, multi-mode fiber, and single-mode fiber products. Optical transmission of up to 30 km is possible. 2. Control signal transmission. Control signals (RTS/CTS signals), ready signals (DTR/DSR), and carrier signals (DCD) are also transmitted transparently. 3. Cross-connection. By setting the switch, control signals can be internally looped back to disable handshaking. This eliminates the need to loop signals within the cable when connecting DTE devices to each other. 4. Connection status monitoring. It monitors the reception status of the RS-232c port and optical port, allowing for display via LEDs and monitoring through rack options. 5. Remote monitoring. By setting the switch, the connection status can be notified to the opposite device. The opposite device can monitor the connection status on the remote side through LED displays or rack mount options.

Company information
Since 1991, our network equipment division has been developing optical-to-metal converters, and since then, we have been engaged in the design, manufacturing, and sales of Ethernet-compliant media converter products. From the beginning, we have maintained a stance of in-house development, prioritizing "high quality," which is a hallmark of domestic manufacturers, as our most important challenge, and we have pursued the enhancement of product value. Finally, in 2010, we became the number one in market share in the domestic media converter market (for businesses and public institutions). We view our market share achievements as a result of our efforts to meet your needs, and we are deeply grateful.
