Ciena NTK553MA – Flexible-Grid Wavelength Switching for High-Degree ROADM Nodes
The Ciena NTK553MA is a Wavelength Selective Switch (WSS) with integrated Optical Power Monitor (OPM), Flex C-Band, 20×1 circuit pack designed for the Ciena 6500 Packet-Optical Platform. As part of the photonic (Layer 0) ROADM layer, this card dynamically routes individual wavelengths across up to 20 switch ports, making it a core building block for high-degree, colorless and directionless optical nodes. Its flexible-grid architecture supports variable channel spacing and coherent super-channels, so it’s ideal for carriers, ISPs, and data center interconnect (DCI) operators scaling 100G/200G/400G+ services. This unit is a cost-effective sourcing option for teams maintaining or expanding an existing Ciena 6500 photonic network.
Key Features & Benefits
- Flexible-Grid (Flex) C-Band Switching – Supports variable-width channels and coherent super-channels instead of fixed 50 GHz slots, letting you carry today’s high-baud 100G–400G+ wavelengths efficiently.
- 20×1 Switch Configuration – A 1×20 wavelength selective switch enables construction of high-degree ROADM nodes with dense nodal connectivity for mesh and DCI topologies.
- Integrated Optical Power Monitor (OPM) – Built-in per-channel power monitoring simplifies commissioning, balancing, and fault isolation without external monitoring cards.
- Native Ciena 6500 Compatibility – Drops directly into the 6500 Packet-Optical Platform photonic layer alongside existing amplifier and ROADM cards.
- Layer 0 Automation Ready – Works within Ciena’s ROADM-based reconfigurable line system for automated wavelength turn-up and dynamic service provisioning.
