Optical Modules PCB
Transceiver boards where insertion loss budget and mechanical registration are decided by the laminate and the etch, not by the layout.
What this application demands of the board
TU-872SLK class low-loss material (Dk 3.8, Df 0.008)
Impedance tolerance to ±5%
Line width and space accuracy ±5%
Small format panelisation with tight outline tolerance
