With the rapid development of 5G network construction all over the world, the demand for optical modules applied for 5G fronthaul networks has seen explosive growth. As a low-cost, low-power, flexible and expandable technology, CWDM (Coarse Wavelength Division Multiplexing) is able to save abundant optical fibre resources for base stations and is one of the leading solutions for 5G fronthaul. In the first quarter of 2020, ATOP overcame the challenges presented by COVID-19 and successfully shipped 10,000 sets (60,000 pcs) of 25G CWDM (wavelength 1270nm ~ 1370nm) products to our customers. ATOP 25G CWDM (wavelength 1270nm * 1370nm) products currently have a monthly capacity of about 4,000 sets (24000 pieces).

This year, ATOP has invested massive funds on expansion projects for high data rate series products in order to strengthen the mass shipment capacity of these products and to expand our own market territory of 5G series optical modules. We have also completed our bid for production facilities, including oscilloscopes and matching modules, spectrographs, high-low temperature chambers and ageing ovens. Project construction is underway and the capacity of 25G CWDM products is anticipated to achieve 12,000 sets (72,000 units) in May and 30,000 sets (180,000 units) in June.

ATOP’s 25G CWDM (wavelength 1270nm ~ 1370nm) optical modules adopt a standard SFP28 packaging form and the device solution is DFB+PIN. The transmission rate can reach up to 25.78Gbps and the wavelength range is from 1270nm to 1370nm. The operating temperature range can support both industrial and commercial levels. The maximum power consumption of the I-temp product is 1.5w and the C-temp product is 1w. The transmission distance can support 10 kilometres and 20 kilometres. The product can be applied for 5G fronthaul. In parallel, 25G CWDM (wavelength 1470nm ~1570nm), 25G BIDI and 25G LR products have already achieved mass production in 2019.

We take “let’s make it personal” as our company slogan as we strive to meet the demands of our clients and create the perfect solutions for our customers. ATOP will continue to utilise its own technology advantages, improve the supply chain system, and enhance R&D and production to strengthen the core competitiveness of the company. Most importantly, we look forward to collaborating with our customers and taking advantage of the indispensable opportunity for 5G development to ensure success for all interested parties.
