A Quick Overview of VERSITRON’s RS 232 Fiber Optic Modem


Fiber optic modems act as a bridge between an internet network and electronic devices. Unlike regular DSL modems, they use a fiber optic cable to transmit signals. This is why, these modems are being used in several applications like inter-network communication systems and data communication systems, wherein high speed data transfer and seamless connectivity are crucial. Depending upon the data transmission protocol, fiber optic modems are categorized into different types, and RS 232 is one among them. The RS-232 fiber optic modem is primarily known as EIA-RS-232 and is an integral part of several serial to Ethernet networks. It is a single-mode modem, thus, one transmitter and one receiver is used for data transmission. EIA or Electronic Industries Alliance designs the standards and protocols for data communication to which these modems comply. Since RS-232 modems are gaining immense popularity, it is essential to source them from a reliable industry leader. Today, it is quite easy to find RS-232 fiber optic modems across brands and VERSITRON stands tall among them. VERSITRON guarantees superior quality RS 232 modems that can convert electrical signals into either single-mode or multi-mode fiber optic light signals. Furthermore, the company offers these modems in either a compact MicroModem or circuit card format.

Protection of RS232 Serial Connections

VERSITRON’s RS-232 fiber optic modems are designed to meet high traffic data transmission demands. Like any other electronic device, these modems are also exposed to vulnerabilities and require protection from power issues. If appropriate protection measures are not taken, then the chances of damage from electrical hazards and failure of network is high. This post gives you insights into VERSITRON's RS 232 fiber optic modems and how to protect them in serial to Ethernet networks and electronic devices.

Why are VERSITRON’s RS-232 Modems Popular?

VERSITRON’s RS-232 fiber optic modem is an efficient solution for establishing intranet connectivity with the connected device or computer. The data here is transmitted by converting electrical signals into light signals for transmission over a fiber cable. This advanced feature-rich and robust product can be used across topologies for short data transmission distances. The RS 232 modem not only supports a wide variety of network types and data rates, but also enables Ethernet local area network (LAN) and wide area network (WAN). Owing to the beneficial features, it is used in several applications. One unusual application includes a university research project that utilizes these micro-modems underwater for counting sea plankton. The following beneficial features of this RS-232 fiber optic modem have contributed to their popularity. So, let’s have a look at them.
  • This RS 232 modem is manufactured in compliance with 802.3 IEEE Ethernet Standards.
  • It’s easy plug-and-play design enables a quick installation.
  • They can support data rates to 100 Kbps source timing and data rates to 128 kbps terminal timing.
  • These modems are available in both standalone and rack mount formats.
  • You can choose between the multi-mode or single-mode configurations depending upon the application requirement.
  • This RS 232 modem also supports SFP fiber optic module technology to convert either 100BaseFX fiber or 1000Base Gigabit fiber.
  • This is applicable for a distance of up to 20km.

How to Protect VERSITRON’s RS-232 Modems From Power Issues?

RS-232 is a fiber optic modem, where fiber optics technology offers adequate protection from ground loop noise and data noise. These modems transmit data in optical pulses, which further reduces the chances of electrocution. Being an advanced technology, fiber optics helps prevent device damage through features like transmission authentication. This transmission authentication enables device pairing using a handshake protocol. In this way, the data only be transmitted when the modems permit to send data. This resolves the problem of data leakage and surge. But do you think your modems require extra protection? If yes, the following techniques would be helpful.
  • Use RS-232 Modems As Short Haul Modems: These modems are named so because they are used for short-distance connections. VERSITRON’s RS-232 modems can be connected to the server or CPU of the Serial to Ethernet network. They offer link protection up to an electric surge of 3 to 6 kilovolts.
  • Install a Data Line Protector: A shunt device is integrated between the computer emulating a terminal and the modem. This helps address the electric surges that are automatically generated in serial communication devices. A data line protector can easily withstand such surges and protects the equipment connected to them.
  • Use Isolation Transformers: They protect modems from external noise, whereas they do not protect from ground noise.

A Few Application Areas of VERSITRON’s RS-232 Modems

These compact-sized modems are used across the following industries.
  • Telecommunication
  • Transportation
  • Entertainment
