RS-485 to Fiber Optic Converter

Point to point/Multi-drop Bus/Self-healing Ring Fiber Links

The RS-485/422 Fiber Optic Converter data series uses the most advanced digital technologies to provide excellent repeatable performance for today's data systems. It supports transmission of one bi-directional data channel over one multimode or singlemode optical fiber. RS232, RS422 and RS485 (2 wire & 4 wire) standards are fully supported. The plug-and-play design ensures ease of installation with no electrical or optical adjustment needed. LED indicators are provided to show the operational status of the unit clearly.
The series is available in compact wall mount or 3U chassis card.

The RS-485/422 Series converter is equipped with a multiple interface circuit that can handle RS-485/422 serial interfaces and multi-mode or single- mode fiber. RS-485/422 converters are used to extend serial transmission distance up to 2 km (multi-mode fiber) or up to 20-100km (single- mode fiber)...Auto Baud Rate DetectionThe RS-485/422 Series incorporates a method for automatically detecting the serial signal baud rate by hardware. This is an extremely convenient feature for the user. Even if a device's baud rate is changed, the signal will still be transmitted through the RS-485/422 to fiber converter without any problem.

RS-232 Multi-Drop Self-Healing Ring Fiber Optic Converter

The Multi-Drop Self-Healing Ring Transmission series products provide an optical self-healing ring network for RS232, RS422 /RS485 data interfaces over two multimode or singlemode optical fibers. The system offers maximum reliability as it can recover simultaneous faults or failures in two different locations and has contact closure outputs on each module to clearly indicate any fault location. The self-healing ring consists of two opposing data paths, ring A and ring B. Under normal operation only the primary path (ring A) is used for data transfer. If a fault is detected, the data is transferred to the secondary path (ring B) without interruption to the communications network.
The series is available in wall mount, DIN rail or 3U chassis card.

Are you planning to install a network transceiver for the internet connection in your system? Do you have the basic knowledge on how the network transceivers work? Here's is a brief discussion on network transceivers which will guide you about its basic functionalities.

The term network is the modified name for transmitter-receiver, which are essentially the devices used for transmitting and receiving the analog and digital signals. Network transceivers are also used as the term, which is common for local-area network (LAN) connection and significantly detects digital signals coming to the network wire as well as transmitting the signals through the same network wire. In most of the modern LANs, the network transceivers are integrated into the network interface card (NIC), whereas, in many other networks, they function as external transmitter-receiver. Therefore, you need to check out what kind of transceivers will function for your network, and based on the criteria, you need to buy appropriate transceivers. In plain terms, a transmitter-receiver is an electronic device and this electronic device plays takes charge of global communication. The efficiency of transmitter -receiver depends on the how compatible it is over the network. Transceivers are known by other names also. For example, in case of Ether networks, transceiver is known for the Medium Access Unit (MAU). Likewise, in case of the radio communications, transmitter-receiver functions as a two way radio where a compatible combination occurs in the form or radio, transmitter and the receiver. Inside a radio unit, the transmitter -receiver exchanges information in half-duplex mode.

Network transceivers come in three configurations, namely chip, board, or module style. The size as well as the process of installation of all three transmitter-receivers is quite different. Chip style network transceiver is the smallest in size and a classic example of nano technology. Chip style network transceiver can be easily installed and removed from the network. Since these types of network are small in size, they are also very easy to handle. Board style transceivers are built or rather integrated directly into a network board or card. These types of transmitter-receiver form the part of motherboard and cannot be easily removed like the Chip style network. Module network transmitter-receivers are exclusively designed to work in the external networks and their installation and function is similar to the many other computer peripheral devices. There are many other designs of module type transmitter-receivers which ideally function as the stand-alone devices.

Transceivers are uniquely designed, and as the result of their uniqueness, they function within the circumference of specifically designed network protocols. The most common and advanced network protocols include AppleTalk®, CANbus, ControlNet, DeviceNet, Ethernet, Fibre Channel, FDDI, Fieldbus, Frame Relay, INTERBUS, PROFIBUS, and xDSL. It is important to know here that when you install the network on to the digital system, you should be aware about its compatibility with the other hardware characteristics. These network protocols are compatible with a particular genre of transmitter-receiver. Some of the quick run through specifications which you need to consider when buying transceivers includes compatibility with the peripherals, do they come with or without full duplex capabilities, different types of connection ports and many more. The full duplex ability of transceivers allows the transmission of data simultaneously to and fro in the network wire
