If you are searching for a datasheet, you are likely looking for specifications on a visible light communication (VLC) component – probably a high-power LED, photodiode, or transmitter module – with a part number ending in 1600.
Official datasheets may be available through these channels: vlc 1600 datasheet
Dermatology and surgery sometimes use 1600 nm for its high water absorption (though less than 1470 nm or 1940 nm). If you are searching for a datasheet, you
Native Master-Slave/Token-Passing (MS/TP) token architecture. vlc 1600 datasheet
The VLC-1600 functions as a native, master-level BACnet Application Specific Controller (B-ASC). It communicates via an physical interface over a standard twisted shielded-pair (TSP) network cable.
