Final HUAWEI OSN3500 we sold in year 2014

During the year 2014, we sold 6th OSN3500 to Asia countries.

Our team just finished the installation prepare yesterday for the last OSN3000.

It was quite a big cabinet, need at least 4 people to handle it.

Ben, our technical manager was testing the power supply before installation.

We think in year 2015, we may more focus on CISCO optical, DWDM technology.the age of SDH is nearly end.
