ATOP 25G DWDM Transceivers Realized Overseas Batch Delivery

According to the latest GSMA report, 42 countries and regions have launched 81 commercial 5G networks all over the world by the end of May 2020. 386 telecom operators from 97 countries and regions have announced their investment in 5G construction. 

As an international transceiver manufacturer, ATOP is deepening its domestic 5G business and is closely cooperating with major domestic operators to conduct in-depth exchanges. At the same time, we intend to stay focused on overseas 5G market trends and actively respond to our customers’ requirements for 5G products. Through these efforts, ATOP’s independently developed and produced 25G DWDM transceiver series has successfully achieved mass supply to many major overseas operators. Moreover, the products have also passed the verification test conducted by a well-known manufacturer of domestic equipment.

ATOP’s 25G DWDM transceivers adopt a standard SFP28 package form with the EML PIN/APD solution. The transmission rate can reach up to 25.78Gbps and the channel supports 21~60. The maximum power of the transceiver is 2.3W with a transmission distance that reaches 10/15 kilometres. With a flexible operating temperature, it is able to support commercial, extended and industrial grade environments.

By applying the transceiver to the fronthaul of 5G network architecture, massive optical fibre resources can be saved while keeping operation and maintenance costs low. However, due to the influence of dispersion, it is difficult for 25G DWDM transceivers to ensure that the transmission distance supports over 15km. To overcome this issue, ATOP is cooperating with chip manufacturers to redress the dispersion problem so that optical modules can transmit data up to 30km. The product is currently in its R&D stage.

ATOP has always been committed to the development and design of DWDM series products. Through years of technology and production experience, great industry chain vertical integration, as well as optical device packaging, ATOP has created a DWDM product chain that is mature and stable. In particular, our 1.25G/2.5G/10G series products have shipped over 100k pcs in the past two years, and its sales records are constantly refreshing.

In the future, ATOP will continue working with customers – both locally and internationally – to seize new market opportunities and write a new chapter of global 5G construction.
