Ciena 6500 WL5e 800G MOTR Module (NTK540BC)

The Ciena NTK540BC is a 6500 WL5e MOTR module designed for high-capacity coherent optical transport across metro, regional, long-haul, data center interconnect, and packet-optical network environments. Built around Ciena’s WaveLogic 5 Extreme technology, the WL5e MOTR platform supports programmable coherent transmission from 200G to 800G on a single wavelength.

This Ciena 6500 WL5e MOTR module is commonly used by network operators that need to scale existing Ciena 6500 infrastructure while supporting high-bandwidth client services such as 100GbE, 400GbE, and OTU4. The module combines multiple client interfaces with a coherent DWDM line interface, helping providers increase capacity while reducing footprint, power, and cost per bit in supported 6500 shelves.

For organizations upgrading optical transport networks, NTK540BC provides a practical path to add 800G-class wavelength capability into compatible Ciena 6500 packet-optical systems without replacing the entire platform.

Optical Network Benefits & Common Use Cases

• 800G coherent transport: Supports high-capacity wavelength services for networks that need to move more traffic over existing fiber routes.
• 100G and 400G client aggregation: Supports 100GbE, 400GbE, and OTU4 client services for high-bandwidth customer, router, and data center connections.
• Data center interconnect: Helps support DCI environments where large traffic volumes must be transported efficiently between facilities.
• Metro and regional network scaling: Provides programmable capacity options that allow operators to tune wavelength performance to route distance and fiber conditions.
• Long-haul optical transport: WL5e technology is designed for high-performance coherent transmission across demanding network paths.
• 6500 platform modernization: Allows operators to increase capacity within compatible Ciena 6500 D-Series and S-Series shelves.
• Reduced footprint and power per bit: The single-slot MOTR design helps improve capacity density compared with older transport approaches.
