Product Overview  Serial optical transceiver is also known as optical data transceiver. Serial optical transceiver (optical data transceiver) can help transmit RS232 signal, RS422 signal or RS485 signal in an optical fiber by converting it into optical signal, and the optical interface is an FC screw interface, which can simultaneously support 2-channel RS-485 data or 1-channel RS-422 data, for zero-latency automatic forwarding, asynchronous transmission, and point-to-multipoint application. RS-485/422 interface is converted with optical fiber, and the maximum communication rate >500Kbps. The interface provides 1500W surge protection and 15KV electrostatic protection. Serial optical transceiver is usually used in pairs, with optical fiber used for long-distance transmission of serial data. It is extensively applied to such systems as industrial automatic control, access control, all-purpose card and parking lot,etc.  Product Features  *Simultaneously support 2-channel RS-485 data or 1-channel RS-422 data *Self-adapt to mono/multi-mode optical fibers *Zero-latency automatic forwarding *Asynchronous transmission, point-to-multipoint application, and RS-485/422 interface conversion with optical fiber *Maximum communication rate>500Kbps *Optical Fiber Interface: FC Screw Base *The interface provides 1500W surge protection and 15KV electrostatic protection *Multi-mode communication reaches 2 kilometers, and mono-mode reaches 20-120 kilometers *Scope of Application: such systems as industrial automatic control, access control, all-purpose card and parking lot, etc.  Communication Indicators  *Standard: meet EIA RS-485 and RS-422 standards *RS-485 signal     A+, B-, GND *RS-422 signal      R+, R-, T+, T-, GND *Optical Fiber Signal: IN, OUT *Working Mode: asynchronous working and point-to-point *Directional Control: automatic data direction control technology is used to automatically distinguish and control data transfer direction *Baud Rate: 0-500Kbps, automatic signal rate detection *Optical Fiber Wavelength: 1310nm/1550nm *Electrical Interface Transmission Range: RS-485/422 interface 1000 meters *Optical Interface Transmission Range: multi-mode 2 kilometers, mono-mode 20-120 kilometers *Interface Protection: 600W surge protection, 1500V electrostatic protection *Load Capacity: RS-485/422 interface supports 32 nodes (128 nodes are customizable) *Electrical Interface Type: 5-bit block terminal  General Indicators  *Input Power: AC220V~12V1A DC power input *Product Size:9.5(cm)*9.2(cm)*2.6(cm) *Package Size:30(cm)*20(cm)*8(cm)
