On ’the nowaday AI world, Optical transmission traffic is explosively growing. The demands for high-speed and large-capacity optical communication networks are becoming more and more urgent. In the past few years, global Internet traffic increased by more than 30% per year. It presents challenges to optical communication networks and makes network upgrading imperative. Considering the multi-rate coexistence and sustainable upgrading for future, the high-degree WSS plays a prominent part in the network. Its application has extended from the ROADM system to the conventional WDM field. It makes the optical transport layer compatible with multiple generations once deployed. It simplifies the maintenance and reduces the post investment.
In order to meet the market demand, Accelink launches the new Twin 2×20 WSS products based on LCOS technology. The company continuously builds the ability of inhouse LCOS technology platform and constantly update L and C+L band integrated products to meet customers' bandwidth expansion requirement.
·Product Features:?Function port expansion: The basic configuration is Twin 2×20 ports which can be upgraded to Twin 2×21/22 ports to support the ASE incident and OXC loopback. It simplifies the test and maintenance as well as increases the control flexibility.
· C6T operating bandwidth: The product is compatible with extended C band applications and extends additional 25% bandwidth. It provides a cost-effective solution for metro network or DCI network expansion.
· Flex Grid: Supporting minimum6.25GHz grid, flexible bandwidth configuration from 37.5GHz to 400GHz, the product can dynamically adapt to different modulation formats of 400G/800G and different scenarios of metro/backbone applications.
· 0~15dB accurate attenuation: Under the single channel independent control, each wavelength supports 0~15dB attenuation adjustment. The step accuracy is 0.1dB and the power balance of the whole network can reach ±0.5dB. Under the single port multi-dimensional control, the wavelength routing and the attenuation value can be programmed synchronously. It realizes "one-click" optical routing optimization and improves the maintenance efficiency by 70%.
· Low cascaded filtering penalty: For single-wave 400G transmission system, 20-stage WSS cascade, the filtering penalty is lower than 1.0dB.
