Differences between a network with PID networking using OA boards and a common network

2

For common networking without PID boards, connecting the built-in VOAs on OA boards is not mandatory. For PID board networking, however, the built-in VOAs on OA boards must be connected because PID boards are commissioning-free and the VOAs need to be automatically adjusted to ensure that the output optical power satisfies requirements.

Differences between an ASON network and a common SDH network
Differences between an ASON network and a common SDH network: In an ASON network, services are classified into several protection levels including diamond, gold, silver, copper and iron. The protection level can be enhanced and the service rerouting function is added in an ASON network. As a result, the actual bandwidth utilization of an ASON network is higher than 50%. A common network does not have the rerouting function.

Types and specifications of OA boards for WDM networks
Fiber amplifiers or OA boards amplify optical signal power to extend the signal transmission distance. The product documentation has described the types and specifications for fiber amplifier boards. For details, see the related topics in the product documentation.

What are the differences between network bridge MAC addresses and common MAC addresses
The two types of MAC addresses have the same functions. Packets bridged by network bridges are complete Ethernet Layer 2 packets.

What are the differences between network bridges and VLANs
Network bridges can implement packet forwarding at Layer 2 on the wide area network (WAN) side. Only Layer 2 interfaces can be added to virtual local area networks (VLANs). Only Layer 3 interfaces can be added to network bridges.
