Industrial Bidirectional RS232 Optical MODEM Serial to Fiber Converter MM ST 2KM

2 km ST interface wavelength of mode optical fiber: 1310 nm

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
