Project Information

Component code TN11OMCA (specific variants such as TN11OMCA01, etc.)

Ordering instructions: When placing an order, please confirm the channel spacing (50GHz/100GHz), splitting ratio configuration (50:50/90:10/95:5), and whether VOA function is required

On site operation supports hot plugging, and anti-static wrist straps should be worn during operation.Pay attention to cleaning the fiber optic connectors

After testing and verifying installation, insertion loss testing, VOA function testing, and port connectivity testing are required

Spare parts management, as the core board of the optical layer, is recommended to configure spare parts at critical nodes

Software dependency requires support from the host software version (recommended V100R005C00 and above)
