■ Optical Alignment
The technician can continuously monitor the optical signal while making adjustments to the alignment.
The Stabilized Light Source (SLS) platform provides a wide range of configurations and options to meet diverse requirements.
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.
The technician can continuously monitor the optical signal while making adjustments to the alignment.
IL measurements can be automatically recorded and analyzed, further enhancing the real-time monitoring capability.
