System Components
The Cisco ONS 15530 has a modular architecture that provides the flexibility to expand the system as
the network grows. The Cisco ONS 15530 components are described in the following sections.
Transponder Line Cards
The Cisco ONS 15530 supports two types of transponder line cards: SM (single-mode) and
MM (multimode). You can install the transponder line cards in any line card slot in the shelf (slots 1 to 4
and 7 to 10).
In the transponder line card, the client signal is regenerated, retimed, and retransmitted on an
ITU-compliant wavelength. The ITU laser on each transponder line card is capable of generating one of
two wavelengths on the trunk side. Thus, there are 16 different transponder line cards (for channels 1–2,
3–4,..., 31–32) to support the 32 channels; each module is available in SM and MM versions. The
wavelength generated is configurable from the CLI (command-line interface).
