Industrial RS485/422 Digital Optical MODEM Serial to Fiber Converter MM SC 2KM

Description:

Multimode Optical Fiber 2 km SC Interface Wavelength: 1310 nm

RS-485/RS-422 Interface Optical Fiber MODEM

I. Overview

RS-485/RS-422 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-485/RS-422 interface, asynchronous transmission, point-to-point application, speed up to 120 kbps

B) Support 9V-260V AC/DC power input

C) RS-485/422 supports 32 nodes (128 customizable nodes)

D) +/-15KV (Human Model) ESD Protection, +/-8KV Contact Discharge

E) Single-mode or multi-mode MODEL (user-customized)

F) Working wavelength: 1310 nm (multimode), 1310 nm (single mode)

G) Automatic detection of signal rate, zero delay automatic forwarding
