The M-CB is a compact bias control board designed to maintain the linear operating point of optical intensity modulators. Featuring a compact miniature design for OEM integration, the M-CB allows for a stable Q+, Q-, Min, Max, and Manual operation over long periods of time. With a single 5 VDC power and RS485 multi-addressing control and monitor interface, the M-CB unit is the ideal choice for industrial and OEM applications when paired with any of Newport’s optical modulators.
