Star Network 8 Channel Date Fiber Hub

Type:FCVH8-VD8 Message

Description:8 channel Aggregation optical transceiver , 8 light direction , With 8*single RS485 fiber modem，1 channel Aggregation equipment replace 8*single RS485 fiber modem

Product Description
                The fiber optic hub for star formation fiber network, RS-232/485/422 transparent transmission on fiber optic star network. Fully adaptive user agreement without changes. As a result of the fiber as a transmission medium, you can completely avoid the threat of harsh environments lightning, surges, electromagnetic interference and other communication devices while eliminating the investment surge lightning protection devices when the original use of copper, greatly improved data communication reliability, security and confidentiality.
Functional Properties
? have the ability to automatically detect the serial signal baud rate
? can automatically detect, RS-485 data flow control, unnecessary use handshake signals to control the flow of data
? Support RS232 / 422/485 interface, RS232 baud rate support 300-256K, RS485 / 422 baud 300-921K
? with eight distal RS232 / 422/485 serial ports Modem consisting Star Network

? automatically detect whether each optical serial data port normal, automatic shield unusual optical interface

      (such as where the fiber optic modem serial bash receive all 0s or short circuit), it does not affect the entire network, and there

       are lights instruction

? There are card-4U chassis support eight fiber hubs, a total of 64 light direction can SNMP network management

? serial port interface lightning reach IEC61000-4-5 (8 / 20μS) differential mode: 6KV, impedance (2Ω);

       Common mode: 6KV, impedance (2Ω) standard
