IV. Main Technical Route and Key Parameters of Selection

Mainstream technologies:

Thin-film filter: mature and economical, suitable for scenarios with fewer channels.

Arrayed waveguide grating: high integration and dense channels.

Wavelength Selective Switch (Micro WSS): A core component for high-end reconfigurable Optical Add-Drop Multiplexer (OADM).

Key selection parameters:

The size and form are 1U rack type, box type, card type and plugable module type.

Channel capability: Supports band, channel number, and interval.

Insertion loss: The lower the parameter value, the greater the system performance margin.

Reconfigurability: Fixed OADM versus Reconfigurable ROADM.

Power consumption and heat dissipation are crucial in compact designs.
