Fiber Data and Voice Links

Fiber Data and Voice Link

Serial-to-fiber media converters, also known as fiber optic modems (FOM), are widely used in industrial systems and commercial applications for the conversion of data signals and electronic communication. The converted signals are transmitted using fiber optic cable assemblies. At Versitron, we provide fiber data and voice links that ensure reliable communications over single-mode, as well as multimode fiber optic cables. We provide the Micromodem style or the FOM II circuit card with chassis fiber optic serial data modems. These fiber serial data modems can easily withstand harsh working environments and conditions. 

Beneficial Features of Fiber Optic Serial Data Modems

Over the years, we have developed fiber optic data and voice links that assure security, greater bandwidth, and EMI/RFI immunity. They can provide uninterrupted signals over large distances while assuring low signal attenuation. In addition to these, the following beneficial features of these fiber optic serial data modems have contributed to their immense popularity and acceptance in the market.

An Overview of Serial to Fiber Converters

Serial to fiber converters are the devices that offer electrical to optical signal conversion for electronic and data signal communication via fiber optic transmission media. These serial to fiber media converters are also known as fiber optic modems or serial data modems. It basically performs full-duplex signal conversion from electric signal to optical signal and vice versa. These serial to fiber optic converters are available in single and multi-channel configurations and are suitable for point-to-point and multi-point transmission. VERSITRON offers high- quality serial to fiber optic converts.


What Are Managed Serial Media Converters Vs Unmanaged Serial Media Converters?

VERSITRON’s serial to fiber data media converters are utilized in copper to fiber-optic communication networks. Our serial media converters are used to connect copper cable and fiber optic data links for electrical and optical data transmission.

According to functionality, our serial media converters are categorized into two types - serial media converters and unmanaged serial media converters.

Let us discuss the difference between managed and unmanaged media converters.

  • Managed Serial Media Converters: The managed serial media converters are serial to fiber converters that allow highly controlled signal conversion. These serial data modems are used in the managed copper to fiber-optic networks. These managed serial media converters offer remote data configuration over large networks, critical monitoring, fault/error detection, etc.  These media converters are used for mission-critical, complex networks. A few prominent features of our managed serial media converters are listed below.
    • Managed serial media converters offer negligible delay over SNMP and VLAN networks.
    • It offers transparent signal conversion as it can be easily controlled.
    • These serial media converters possess advanced monitoring and error detection properties.
    • It offers data protection over data plane, control plane, and network management plane. Therefore, security over complex networks is assured by managed serial media converters.
  • Unmanaged Serial Media Converters: Unmanaged serial media converters are plug and play type of serial to fiber media converters. These types of serial media converters are only sufficient for converting electric data to optical signals from a copper cable to a fiber optic cable. Being the unmanaged type of serial media converters, these converters do not allow control over signal conversion. Therefore, are only used for predetermined output networks. Despite having less control over signal conversion, our unmanaged serial media converts offer the following features.
    • These media converters come as DIP (Dual In-Line Package, which means these converters offer full-duplex switch functions.
    • Our unmanaged serial media converters are equipped with features such as over the duplex mode, auto-negotiation, and signal crossover.
    • Being plug and play types of devices, these converters enable QoS setting, UTP port support over 10/100/1000M cabling, and VLAN network.

Guide to Using Serial Media Converters

VERSITRON, being a prominent supplier of serial data modems or serial media converters, is also promoting the proper use of serial media converters. Read the following information to understand how to use serial media converters.

  • Serial media converters are available in two configurations, namely, RS232 and RS-485. Before using, it is important to understand that RS232 is useful for single inputs and multiple output signal conversion. Whereas, RS485 is suitable for multiple inputs and single or multiple output type connections. Now let us discuss how to use these serial media converters.
  • Irrespective of the configuration, the first serial data modem is to be attached to the input control system from where the electric signal is taken as input. Further, the operator needs to connect the first serial data modem to another serial data modem which connects to the output signal controlling system. The connecting media between two serial to fiber data converters or modems is fiber optic cable. The electronic to optical signal conversion can be reversed via the modem functionality itself.

This is the regular process of integrating serial data modem within a copper to fiber conversion network.

Gain an Understanding on the Workings of Serial to Fiber Optic Converters

The working principle of serial to fiber media converter depends upon the type of topology it is integrated into. The main function of electric to optical signal conversion and reverse conversion remains the same. However, the working principle differs based on the input and output requirements of a copper-fiber optic network. Let us discuss two different typologies of serial media converters in order to establish a fiber-optic data link.

  • Pair Connection Topology/Mode: In the pair topology, two serial media converters are connected in series with a serial device. This enables point-to-point data conversion. This topology is suitable for a 20 km distance of data conversion. However, the number of input and output can be varied depending on the configuration of the media converter and input/output signal controlling unit.
  • Ring Topology/Mode: In the ring topology, multiple serial media converters are interconnected to form a loop that enables fiber optic data link. Each converter is connected to two neighboring media converters and the signal is alternately converted from electric to optical and vice versa via alternating converters. This type of topology allows 100 km of transmission. The only drawback is if one converter fails to convert, the entire network fails. This still can be used over managed serial media converters in order to ensure controlled and optimized performance and data conversion.
