It also helps service providers take advantage of CDC ROADM architectures. This enables super-channel switching at the optical layer, Layer 0, within an optical mesh network, improving overall network switching capability and thus resulting in enhanced network efficiency. Moreover, Instant Bandwidth allows providers to adopt a cashflow-efficient business model in which additional bandwidth can be deployed rapidly with a few mouse clicks when demand increases. There is no need to order, install and deploy additional equipment. New services can be activated remotely in an instant, resulting in faster time to revenue.

The XT Series provides high levels of reliability, low space and power consumption and operational simplicity. It enables network operators to achieve operational scale while reducing the total cost of ownership (TCO) of transport networks in high-capacity point-to-point interconnect and mesh applications across DCI, metro and long-haul networks.

Similar to the XT Series, the XTS Series combines 2.4T super-channels with sliceable photonics and in-flight line-rate Layer 1 encryption in a compact, low-power form factor. In addition, it features subsea-optimized modulation formats such as ME-PSK and 3QAM, as well as Infinera’s Advanced Coherent Toolkit featuring the industry’s first commercially available Nyquist subcarriers to enhance capacity-reach performance.

The XTS Series enables super-channels to be sliced, providing wavelength-level granularity, so each wavelength can be tuned across the C-band, modulated and then routed to the appropriate destination. The XTS Series platforms are the industry’s first subsea transport-optimized meshponders, combining muxponder technology with sliceable photonics in a server-like WDM appliance. The XTS Series features new subsea software tools like dynamic spectral sharing, which enhances Infinera’s open architecture by allowing subsea operators to partition and monetize valuable fiber spectrum, which can be now be safely and securely shared with multiple customer tenants, independent of both cable and submarine line terminal equipment suppliers. Mission-critical subsea link performance data is available in real time on demand via open SDN APIs. Subsea operators can monitor transmission health as well as identify opportunities for capacity adjustments.

The XTS Series includes the following platforms:

  • The XTS-3300 delivers up to 1.2T of line-side capacity in 1RU and provides enhanced capacity and reach for subsea applications in an ultra-compact form factor at 600 mm rack depth, with low power consumption.
