SLS-100 is the most common configuration type. This configuration has discrete sources for each output channel. Each channel can have a single wavelength source or combined output consisting of two or more wavelengths. The most common configurations consist of:

Banks of single wavelength sources: These can consist of multiple channels with a single wavelength light source on each. One can also choose multiple clusters of channels with the same wavelength. Common systems include 24ch 1310 nm FP lasers, where all ports have a discrete laser for each channel or the system can be split into multiple clusters, like having ports 1 to 6 at 1310, 7 to 12 at 1490 nm, 13 to 18 at 1550 nm, and 19 to 24 at 1625 nm.

Banks of dual wavelength sources: This system might consist of 24 channels with 850 nm and 1300 nm LEDs coupled into each channel. In this case, one wavelength is active on each port at a time and the user can toggle between 850 or 1300 nm for each channel.

Source with coupler or splitter option: These systems can have couplers internally to split source power across multiple ports.

SLS-110 is the internally switched configuration. This configuration allows for one set of sources that get switched into multiple output channels. The most common configurations include:

Switched set of sources: One example is a set of 1310 nm FP and 1550 nm FP lasers combined and switched to 24 outputs. This provides 1310/1550 across 24 channels. For the SLS-110 light is only present on one port at a time.

SLS-120 is a CWDM configuration. This configuration allows for all CWDM wavelengths (1270nm to 1610nm with 20nm spacing) using DFB sources ± 5nm from nominal. Some common configurations are:

CWDM4: This is a system with 4 outputs consisting of DFB lasers at 1270, 1290, 1310, 1330nm.
