Looking for This Equipment?

The Ciena NTK553LB (HECI/CLEI: WOWUBD0EAC) is a Wavelength Selective Switch (WSS) Flex C-Band with OPM, 9×1, for the Ciena 6500 Packet-Optical Platform. Specifically, the NTK553LB gives operators per-wavelength control over which DWDM channels they add, drop, pass through, or switch at a node. As a result, it forms the core of a flexible, multi-degree 6500 ROADM.

NTK553LB 9×1 Switching for Multi-Degree ROADMs

In addition, the NTK553LB’s nine input ports support multi-degree configurations for ring and mesh networks. Consequently, carriers can route wavelengths remotely, without truck rolls or manual fiber changes. Moreover, the card occupies two slots in the 6500 shelf.

Flexible Grid Ready

Furthermore, the NTK553LB supports 50 GHz channel spacing today. Unlike the NTK553LA, it also supports flexible grid applications with traffic channels wider than 500 GHz. Therefore, it gives operators a path to future high-baud-rate coherent wavelengths without replacing the WSS.

Built-In Optical Power Monitoring (OPM)

The integrated OPM measures the power of each wavelength passing through the switch. For this reason, operators can balance channel power and spot problems without separate test equipment. Likewise, the 6500 uses this data to automate power control across the line.

Where the NTK553LB Fits

For these reasons, the NTK553LB suits metro and long-haul 6500 networks that need dynamic, multi-degree wavelength routing, as well as spares for deployed 6500 ROADM fleets. By comparison, the Fujitsu FC9565W8C1 9×1 WSS serves the same role on FLASHWAVE 9500 networks. For more on the platform, see Ciena’s 6500 Packet-Optical Platform overview.
