Sino-Telecom Technology Co., Inc.

Overview

OA1 is a single-stage optical amplifier. it can further extend the transmission distance of signals. Moreover, WDM transmission can be achieved by using DWDM multiplexer/demultiplexer, which is especially suitable for long-distance trunk line network, MAN (metropolitan area network), access network and various SDH/PDH transmission systems.

Features

● Adjustable gain;

● High and flat gain, low noise;

● ACC, APC and AGC are optional;

● Support amplification through two stages. OADM or DCM modules can be accessed in the middle;

● Compact structure and modular design which supports hot plug;

● Parameters can be set and viewed in the graphical interface.
