Overview

MXT-OTP3000 is a kind of wideband opto-electricity transmission platform, which is characterized by good generality, high installation density, powerful function, flexible combination and various telecommunication management modes. The platform basic configurations are fan cooling configuration, status display and monitor unit, and single power supply module. There are several application modules optional, including forward optical transmission, forward optical receiving, reverse optical receiving, EDFA, optical switch, RF switch,, forward driving amplifying and power supply module.  


Features

● 19” (3RU) standard chassis, it can save space and be easy to install.

● Each chassis has 12 slots with completely same function and shape, and each application module can be installed randomly.  

● Open-rack design and the overall duct-type design of application module can be easy to dissipate

heat in maximum, to improve the unit’s reliability.

● Post-cooling fan can be no stopping to exchange in the scene so as to repair and maintain.

● Intelligent status focuses on monitoring units, real-timely monitors each module’s operation

parameter inside the rack, and realizes automatic sound and light alarm in sudden fault.

● Standard RJ45 network management telecommunication interface, which can be easy to realize

remote central monitor.


1.PS250 power supply module

Features

PS250 series power supply is a high-reliability power supply system of latest switch power structure, which has small volume, high efficiency energy conversion, small interference harmonic and large output power characteristics. The input power can be converted into +24DC, +5DC and -5DC and provide to a system rack application module for use. It can be configured two PS250 power supply modules at most inside the rack to operate in the mode of online hot backup.
