INFORMATION

Overview

16E1
fiber optical multiplexer can multiplex to 16 E1 and 8Ethernet signals for transmission over an optical fiber,
resulting in reaching a longer distance without a repeaters and superior
performance compared to copper media.

The
16E1 fiber optical multiplexer is the 16E1 point-to-point optical transport
equipment that uses the FPGA chips and it is easy to upgrade. The outer design
use the standard 19 inches rack, so the volume is little, weight is light and
operation is convenient and credit.

The
16E1 fiber multiplexer can support kinds managements (SNMP,CONSOL etc.It is
easy for operation and maintain.

Features

   ●   Provides 16 E1 transparent transmission ;
