RS485/RS422/RS232 Data fiber modem

Introduction

     Fiber modem implements advanced optic transmission technology to extend signal transmission distance up to 120km on single-core fiber. It can convert data type among RS232, RS422 and RS485 by one circuit or multi-circuit. With features of HV-free，electromagnetic-free and thunder-lightning protection, fiber modem is widely used in industrial control, automatic electricity system, and traffic control etc.

Features   

* Comply with EIA RS-232/485/422 standard.

* Industrial-grade design, SMT arts and crafts.

* Self- negotiate without delayed

* Asynchronous transmission, In point-to-point mode, RS422 connector convert with fiber optic.

* Self-detect the rate of serial port, distinguish and control direction of data transmission.

* The largest communication rate:120Kbps

* External power supply 5V DC or 220V AC, dispense with steeling electricity of serial port, high adaptability.

* Single or multimode optional, FC/SC/ST optional.

* Operating Wavelength:1310nm/1550nm(single mode), 1310nm, 1550nm

* Supply 1500W surge protection, 15KV static protection, with thunder and lightning protection.

* Multimode communication reach 2 km, single mode reaches 120 km.

* Power and video status indicators LED can monitor the system operating conditions

* Plug and play , Hot-swap function

* Supports for centralized management 19" 2U 16 rack-mount chassis
