Description

Perle PSI-MOS-RS485W2/FO 850 E Transceiver/Media Converter – 1 x ST Ports – DuplexST Port – Multi-mode – 2.61 Mile – Power Supply – Rail-mountable

The PSI-MOS-RS485W2/FO 850 E can be used to convert RS485 2-wire devices to fiber optics. By transmitting serial data over optical fiber, these serial to fiber converters provide an economical path to extend the reach of RS485 devices. All protocols with 10/11-bit UART data format and NRZ data coding are supported. This includes popular protocols such as:

  • Modbus ASCII / MODBUS RTU
  • SUCONET K
  • S-BUS
  • DH-485, and more…

Long Distance Serial Data Transmission over Fiber

RS485 Serial transmission is commonly limited to 100 kbps over a distance of only 1200 meters (4000 feet). Using the FO 850 E Serial to Fiber Converter you can extend your serial data transmission up to 4.2km (2.6 miles). The result is that any two pieces of asynchronous serial equipment, located miles apart, can communicate at half duplex over fiber optic cable at rates up to 500 kbps.

EMI, RFI and Transient Surge Immunity

Another advantage of the FO 850 E fiber optic transmission system is the electrically isolated connection of devices. Electromagnetic interference (EMI) is a common phenomenon in typical environments like industrial plants, warehouses and factory floors. This interference can cause corruption of data over RS485 or copper-based Ethernet links. Data transmitted over fiber optic cable however is completely immune to this type of noise, thus preventing the negative effects of voltage equalization currents and electromagnetic interference on the data cables. A Serial to Fiber Media Converter therefore enables you to inter-connect your serial devices over fiber ensuring optimal data transmission, increased availability of the system, and improved network design flexibility for point-to-point connections and star structures.

Flexible Fiber Optic Connections

The FO 850 E operates at 850 nm wavelength, using a separate LED emitter and photo-detector on ST type connectors. Almost any multimode glass fiber size can be used including 50/125 m, 62.5/125 m, and 200/230 m.

Power Budget Considerations

Calculating the power budget is critically important with planning the fiber optic link. The optical power budget is the amount of light required to transmit data successfully over distance through a fiber-optic connection. The amount of light energy available within the setup will dictate the length of the fiber optic cable run between serial media converters within the network. Optical power budgets are critical to help businesses avoid signal distortion. To learn how to calculate optical power budget read our technical note. Transmit and receive dBm can be found in the Hardware specifications.

Transmit each serial signal out over 10 fiber optic lines

Up to ten (10) Serial to Fiber Converters can be grouped together using the TBUS DIN Rail bus system for voltage and data. This allows the serial converter to operate as a star coupler, taking the serial data input signal and distributing it to all Fiber optic output ports.
