Serial to Fiber Converters

Fiber Data and Voice Link
Serial to fiber converters are used in industrial and commercial applications to connect RS232, RS485, and RS422 serial devices to fiber optic cables. At VERSITRON, we provide serial to fiber optic converters that ensure reliable communications over single-mode and multimode fiber optic cables. Our selections feature various types of serial to fiber converters including the smaller compact Micromodems or the FOM II circuit card fiber optic serial data modem format. These serial to fiber optic converters are designed to work in harsh working environments.

Beneficial Features of Serial to Fiber Converters

Electromagnetic interference (EMI) is known to impact the performance of traditional copper links. This EMI has been a matter of concern for industrial facilities. Knowing this, we have developed serial to fiber converters that assure excellent EMI/RFI immunity, data security, and great bandwidth. These serial to fiber converters assure good quality long-distance signals with low attenuation. Unlike other devices, the signal quality remains consistent throughout the transmission distance. This makes them popular with our customers. We believe the following beneficial features have contributed to their easy acceptance among our client base.
  • Both of Our FOM II series modems and Micromodems feature SFP Ports, which enable easy data transfer between the networking equipment and fiber optic cable. All our modems are equipped with LC connectors.
  • FOM II series products are also compatible with our Micromodem products, and they assure excellent flexibility. Featuring multiple connection options, they assure seamless connectivity when connected to other devices.
  • Our FOM II fiber optic serial data modems are compatible with RS-232, RS-422, RS-449, RS-485, and V.35 converters.
  • VERSITRON’s FOM II high-speed fiber optic modems are widely used in military applications, as they support the conversion of MIL-STD-188-114A (balanced) and MIL-STD-188-114A (unbalanced) signals.
  • Our fiber optic serial data converter modems are compatible with point-to-point link, redundant ring, or multidrop networks.
  • Our fiber optic Micromodems are compact sized, and their small footprint has proven to be an advantage for applications facing space constraints.
  • In applications demanding small equipment, you can easily mix and match these modems, and also utilize the compatibility between MicroModem devices and FOM II modems to your advantage.
  • The Micromodems are used in various challenging applications such as underwater applications and airport applications to ensure long-distance signal transmission and safe operation. 
  • These fiber optic Micromodems feature multiple connections, and they can be easily connected to the data terminals or other communication equipment.
  • We also provide various accessories with Micromodems such as serial connectors and power jumpers.
  • You can easily choose between different chasses such as HF-20A (20-slot chassis), HF1 (one slot chassis) and HF-2SS (side by side chassis).
  • The MRR-16 Micromodem chassis can house up to 16 “Micros”.
  • All our modems support synchronous, asynchronous, and isochronous data transmission.
  • They assure transparent operations in all conditions.

Applications of Serial to Fiber Optic Converters

Our serial to fiber optic converter are used in serial networks, long-distance networks, and high EMI environments. These are widely used for data control and communication in various applications such as
  • Traffic monitoring
  • Manufacturing/assembly platforms
  • Underwater data communication for submerged equipment
  • Airports

How to Use Serial to Fiber Media Converters

At VERSITRON, we have been designing and developing serial to fiber converters for over six decades. They have been an integral part of several traditional transmission networks. Today, they are a part of hybrid copper and fiber optic networks too. How do these serial to fiber converters work? How do they support electrical to optical signal conversion? The following pointers will help you understand the working of these devices better.
  • The serial media converters support RS-232 and RS-485 connectors. Of these, the RS-485 are suited for multiple inputs, as well as multiple or single output type connections. However, RS-232 is suited for single input and multiple output signal conversions.
  • The serial data modem is connected to the input system where it takes the electrical signal as an input. This modem is connected to another data modem, which is further connected to the output controlling system.
  • This connectivity helps ensure consistent signal conversion and fiber optic cables are used for connecting two serial data converters.
  • The fiber optic cables support electrical to optical signal conversion. However, this signal conversion can be reversed through the modem.

Working Principle of Serial to Fiber Optic Converters

Like any other networking device, the working principle of the serial to fiber media converter also depends on the topology it is integrated into. Electrical to optical signal conversion and optical to electrical conversion are performed in a similar way across these devices. The working principle of serial to fiber converter will differ as per the input, output, and transmission requirements of the network. The following are two popular topologies, which are widely adopted by industrial networks across the globe. Gaining an understanding of these topologies will help you understand the workings of these devices as well.
  • Ring Mode/Topology: This topology features a loop of serial media converters that are interconnected to each other. A converter may be connected to two other media converters, and the signal conversion from electrical to optical or vice versa takes place between these alternating converters. Ring topology is usually employed for long-distance transmissions. It supports up to 100km transmission. High dependability is touted as one of the main drawbacks of this topology. If one converter fails to perform, it may affect the performance of the entire loop. Ring topology is also suited for managed serial media converters. When connected in a ring mode, the features of managed switches are put best to use and they assure optimized performance and better data conversion.
  • Pair Connection Mode/Topology: As the name suggests, in this topology, two serial media converters are connected to a serial device in series. This assures quick point-to-point data conversion. Although effective, this topology is best suited for short distances such as 20 km networks and so on. The inputs and outputs will vary as per the connections of the output/input signal controlling unit and media converters.
