Perle PSI-MOS-RS422/FO 850 T Transceiver/Media Converter 27083974
For applications where redundancy is required, the PSI-MOS-RS422/FO 850 T Serial to Fiber Converter transparently connects 4-wire RS422/RS485 and INTERBUS devices to two fiber optic cables. By transmitting serial data over optical fiber, these serial media converters provide an economical path to extend the reach of RS422 and RS485 devices. The serial data input is transmitted out both fiber ports to different locations or back-up systems. Expandable Serial to Fiber Network infrastructuresUp 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 in additional network topology environments:
With the FO 850 T Serial to Fiber Converter you can extend your serial data transmission up to 4.2km (2.6 miles). Therefore, any two pieces of asynchronous serial equipment, located miles apart, can communicate at full duplex over fiber optic cable at rates up to 2 Mbps. EMI, RFI and Transient Surge ImmunityAnother advantage of the FO 850 T 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 RS422 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 ConnectionsThe FO 850 T 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 ConsiderationsCalculating 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. |
