![]() It features 12 user-selectable data rates from 300 bps up to 460.8 kbps. Using optical fiber to generate a two-micron laser: Lasers with a wavelength of two microns could move the boundaries of surgery and molecule detection. You get the speed with the RS-422 and RS-485 Optical Isolator/Repeater too. By connecting one side of the unit as a 2-wire device and one side as a 4-wire device equipment meant for a point-to-point RS-422 interface can be connected directly to an RS-485 2-wire multidrop system. The RS-422 and RS-485 Optical Isolator/ Repeater operate in either 2-wire half-duplex systems or in 4-wire half-duplex or full-duplex systems. It supports Transmit Data A and B Receive Data A and B Protective Ground and Signal Ground. The RS-422 and RS-485 Optical Isolator/Repeater use terminal blocks on each side of the device. All data lines as well as power and ground are isolated from one side of the unit to the other. It can be used to optically isolate one piece of RS-485 equipment from the rest of an RS-485 system or one local group of RS-485 equipment from another or it can be used as a repeater to expand an existing RS-485 system beyond the standard's 32-node limitation. Optical Isolators Thorlabs manufactures a wide selection of narrowband and broadband free-space optical isolators (Faraday isolators) that operate in spectral ranges from 365 nm to 4.55 m, including high-power options, as well as fiber isolators designed for wavelength ranges from 650 to 2010 nm for polarization-independent versions and 770 nm to 2010 nm for polarization-dependent versions. The unique manufacturing process and optical path. The BLACK BOX(r) RS-422 and RS-485 Optical Isolator/Repeater enable you to connect equipment meant for a point-to-point RS-422 4-wire interface to an RS-485 2-wire multidrop system. The 2 m Polarization Insensitive Isolator is designed and manufactured according to Telcordia standard. This compact device links RS-422 4-wire and RS-485 2-wire systems while using optical isolation to protect equipment and lines from damaging ground loops. Features 12 user-selectable data rates up to 460.8 kbps. Operates 2-wire half-duplex or 4-wire half- or full-duplex. It can be used as a repeater to expand an RS-485 system beyond 32 nodes. Connects point-to-point RS-422 4-wire equipment to an RS-485 2-wire multidrop system. Isolates one RS-485 device from the rest of an RS-485 system or one local group of RS-485 equipment from another. The potential of single-crystal silicon as a magneto-optical material for Faraday isolators operating at room as well as at cryogenic temperature in a high-power laser radiation was considered. The optical repeaters/isolators add 4,000 feet (1.2 km) and another 32 nodes to an RS485 data circuit. material allowed developing an Faraday isolator with compensation of thermally induced depolarization without reciprocal rotator with estimated maxP180 W. ![]()
