Single-mode optical fiber 20 km ST interface wavelength: 1310 nm for other models to see order information.
RS-232 Interface Optical Fiber MODEM
I. overview
RS-232 interface optical fiber MODEM is a controller connecting remote terminal unit (RTU) to host (HOST) or distributed data acquisition system (SCADA). The product uses optical fiber as transmission medium, which improves the transmission performance of the system and effectively avoids the threat of lightning, surge and electromagnetic interference to communication equipment in harsh environment.
II. Functions and Characteristics
A) Support RS-232 interface, asynchronous transmission, point-to-point application, speed up to 120 Kbps
B) Support 9V-260V AC/DC wide voltage input
C) +/-15KV (Human Model) ESD Protection, +/-8KV Contact Discharge
D) Single-mode MODEL or multi-mode MODEL, (customized according to user)
E) Working wavelength: 1310 nm (multi-mode), 1310 nm (single-mode)
F) Automatic detection of signal rate, zero delay automatic forwarding
